To de-worming medication flowers counterpart
In actual production , flowers , like other crops are also vulnerable to a variety of pest infestation . Flowers in the fight against pests , such as insects according to different mouthparts symptomatic spraying , to improve the control effect will be of great benefit.
Chewing mouthparts of insects , such as yellow slug , the day suddenly caterpillars, beetle daisy , leaf miner , grubs , black cutworm , mole crickets, flies and other species , damage flowers , fruit tree sprayer the principal cause floral tissue mechanical damage. Leaf feeding pests such as flowers , leaves often cause defects , and even leaves eaten ; eats flowers, stems , fruits and seeds of pest infestation drill into its internal organization , often caused by holes in the surface , the formation of worms in the internal tract ( such as chrysanthemum beetles, bees , etc. rose stems ) ; lurking in leaf epidermal between feeding pests leaves left in the serpentine road insects , often the leaves wither , caducous ; feeding after sowing seed , seedling roots , corms , bulbs and tubers and other flowers underground pests , often caused Deficiency or seedling lodging, and even whole dead . Flowers in the fight against chewing insects , the stomach may be the preferred toxic pesticides , the most commonly used agents have trichlorfon , sodium fluoride , etc. The absorption of chemical agents such as monocrotophos, omethoate and other chewing mouthparts and has a good killing effect .
For sucking mouthparts , which feeding method is to use the mouth needle into flower leaves, flowers, shoots , stems and other tissues , drawing juice. Flower shape suffer no mechanical damage , only parts of the formation in the victim faded spots, or cause tissue malformations ( such as wrinkled leaves , leaf , galls , etc. ) , common pests sucking mouthparts scale insects, aphids, thrips , whiteflies , mites and other insects. In the fight against sucking mouthparts damage , the drug of choice is a systemic insecticide , such as omethoate , monocrotophos , carbofuran and so on.manual sprayer Contact toxicity of insecticides such as malathion , phoxim , cypermethrin , deltamethrin and other pests on flowers and has a good control effect. It should be noted that the prevention of gastric toxicity of pesticides on flower sucking mouthparts pests largely ineffective .

Precautions to improve herbicide efficacy
Note that the right choice according to crop and weed herbicide right choice herbicides. If Tribenuron for wheat in the northern broadleaf weeds , grass weeds good effect on wheat relatively safe , but if it will be used on crops such as rapeseed fields produce injury , and even death rapeseed .
Note that the selected medication suitable period of nature according to herbicides , weeds occurred during the selected medication timing. Soil treatment medication, such as acetochlor in crops after sowing , pre-emergence weed medication, can increase efficacy ; seedling foliar treatment medication should be in before the 2-leaf stage of weeds and crop 2 leaf stage after medication. In addition, some will be affected by the level of herbicide efficacy light , temperature, soil moisture effects, such as glyphosate and other high efficacy in the sun is strong , it should choose a sunny spraying ; Chlortoluron , dicamba , etc. at 5 ℃ the following herbicidal effect is poor, it should be avoided before and after cold medication ;perfume sprayer acetochlor herbicide in the soil humidity, good effect, if the drought, irrigation or rainfall should be after the spraying.
Note pharmaceutical formulation and application techniques to improve WP watered administered , can be washed with a small amount of water to preweighed medicament into a paste, then pour the sprayer , then add the right amount of water to mix. Special small amount ( about 1 gram per acre ) , plus a small amount of water should be first dubbed Pharmacy liquor , into sprayer , add water and mix thoroughly diluted to the desired concentration . Liquid herbicides should first spray by adding a certain amount of water, then add the additional dose, and then injected into the water to be added and stirring plus side . Use clean water liquid preparation, such as glyphosate added easily mud muddy water adsorption passivation agents , reduce the efficacy. Mu water generally 30 to 45 kg is appropriate . When spraying should also pay attention to the frequency of the hand pressure sprayer , human walking speed , nozzle height remained the same ,portable sprayers and each spray pattern width to be the same , to avoid re-spray , leak spray , spraying should be careful not to let drugs fog drift to other neighboring crops .
Note mix , alternating the use of herbicides with herbicides used continuously for many years , easily lead to resistant weeds , so herbicides only mixed-use and inter-annual used interchangeably in order to achieve the purpose of long-term control of weeds .

How to avoid injury occurred flowers
Although you can control the use of chemical pesticides flower pests, but improper use can easily cause flower injury, injury can generally be divided into acute injury and chronic injury. The main symptoms of leaf spots appear uniform , leaf edges curl scorch , plant growth is slow , serious and even lead to death. So be sure to strictly control the use of pesticides concentrations and doses , as found using standard doses and concentrations of pesticides can not achieve the desired results , you should replace pesticides . Not at liberty to mix pesticides in order to avoid injury.
First, the random mix pesticides : When flowers diseases, pests occur simultaneously, people usually will insecticide, fungicide mix , took two of three insecticides , and some even joined the foliage . If the same performance between several pesticides , pH value close to the chemical reaction does not occur , there is no effect on the efficacy , otherwise it will affect the efficacy of play , but also produce injury. Such as Bordeaux mixture is to use copper sulfate , lime and water prepared from suspensions, which can control a variety of fungal diseases which have an alkaline liquid , which are not commonly used pesticides , nor with lime sulfur , turpentine agent mix , otherwise it will reduce the efficacy , resulting in injury. Therefore pesticides , we must first understand their pharmacological properties , can mix the mix , then you must not mix the used alone .
Second, the spraying time , inappropriate methods : water power sprayer spraying cycle is too short in the different stages of pests and diseases , pesticide spraying the cycle length is different, generally in early stage two weeks time, the peak once a week. In fact, many difficult to kill pests , bacteria difficult to eradicate , and some growers to frequent drug use , some three days with a single , or even one day be used once , the results did not kill insects , disease did not eradicate , flowers, seedlings , it was an injury. In this case, we must strictly control the spraying cycle , otherwise injury also intractable than the pest . Should pay attention to the prevention and control of pesticides used alternately to prevent resistance to pests and pathogens , causing frequent spraying , eventually leading to injury ; Some florists in spraying pesticides , no spray to the key parts of the drug , sometimes in a a part of the residence time is too long, so a lot of syrup stranded in the leaf surface , causing injury flowers , old leaves and large this phenomenon is particularly evident on the leaves .
Third, the dispensing process is not standardized : chemical formulations are many, wettable powder, emulsion , tablets , granules , solutions, etc. , some of them can be dissolved directly forms , some can not completely dissolved. Undissolved particles suspended in solution, easy to clog the nozzles when garden pressure sprayer spraying , even smaller particles ejected from the nozzle , also remain in the leaf surface , resulting in localized plant phytotoxicity . Therefore, in dispensing , pay attention to strict accordance with procedures , different formulations of pesticides first dissolved in a small container and then transferred to a large container until completely dissolved or melted evenly and then transferred to the sprayer .

Catfish fish rice farming pesticide use matters
Fish in paddy fields , although the fish can eat some insects, but in order to ensure high and stable yield of rice , but also requires the use of pesticides to control rice pests . Application of pesticides in fish in rice fields , it is necessary to be effective in the control of rice pests and diseases, but also to ensure the safety of fish and reduce the pollution of the water environment . Therefore, you must do the following.
1 , the choice of high efficiency, low toxicity and residue , broad-spectrum pesticides, prohibit the use of highly toxic pesticides on fish species ; aqueous or oil should be more choice , sprayer less or no powder pesticides.
Try different kinds of pesticides used interchangeably, both preventable and resistant to pests and diseases , but also can reduce the pesticide in rice , fish residues .
Common efficiency and low toxicity pesticide residue are: trichlorfon , dimethoate , Bisultap , leafhoppers scattered Jinggangmycin , leaf blight net and so on. Toxaphene , Phenthoate , pyrethrum , rotenone , Bordeaux mixture toxicity, prohibited. Overall, the general toxicity of organophosphorus pesticides is relatively low , may be appropriate to use ; organochlorine pesticide toxicity is relatively high, as little as possible with or without .
2, according to the occurrence of rice pests and timely use of pesticides , the correct calculation of the dosage, dosage and frequency of strictly controlled .
3 , adopt comprehensive prevention and control measures , in addition to the use of chemical pesticides to control , shall promote biological and microbiological pesticides to control , in order to help protect the rice ecosystem environment, protect natural enemies of pests ,plastic sprayer reduce chemical pesticide use and residue caused by pollution. To properly grasp both the normal usage of pesticides and safe concentration for fish , so as to ensure the application of pesticides when the safety of fish .

The use of bio- pesticides technical points
Pollution-free agricultural production has become the development direction of agricultural production . Agricultural products in the production process, the use of biological pesticides to control pests and diseases have attracted worldwide attention. Currently , bio-pesticides in food, vegetables, fruit trees, flowers , widely used . However,backpack garden sprayers due to the effect of biological pesticide use is affected by many factors. In practical applications, there are a series of problems . The scientific use of biological pesticides should make maximum use of favorable factors, to overcome and avoid disadvantages. In use should pay attention to the following points.
First, choose a different control objects according to different varieties of pesticides currently producing bio-pesticides are insecticides, fungicides and use of microbial products made on behalf } antibiotic insecticides, fungicides and other types. In the practical application of biological pesticides . Many people on the nature of biological pesticides are not completely understood, mistaken biological insecticide, fungicide can prevent all diseases , pests , rather than indiscriminate widespread use , it will not only not receive the desired effects , but also delays Prevention period. Highly selective biological drugs , such as Bacillus thuringiensis (Bt) effective prevention and treatment of Lepidoptera larvae , but not leafhopper Homoptera pathogenicity , and different varieties of Bacillus thuringiensis based on several important pests effect there are differences . Further , according to the characteristics of different types of pest feeding biological pesticides, such as insects of Lepidoptera Bt good results, will be distributed in plants after spraying the surface , or touch the feeding insects dead bacteria , but the sap sucking insects ( such as aphids , mites ) invalid, and avermectin mites killing effect is very good. Therefore, for different types of pests targeted selection of suitable varieties of bio-pesticides .
Two , according to the control object and conditions of the appropriate choice of bio- pesticide formulations of biological control effects often associated with pesticide formulations and is closely related to the use of technology , when used according to the control object , meteorological conditions and the use of time, the right to select the appropriate dosage forms , in order to achieve the best control effect. Such as powders can make use of air buoyancy and wind dispersed in a wider range , hand sprayers and thus have a greater exposure and pests ; For a large amount of leaf-eating pests such as Pieris water can be dubbed the WP suspension spray method was better than well, while the use of dusting method less effective. Capsules release the result is not only longer . Pathogens but also to protect them from environmental factors. Applicator can be used in greenhouses .
Third, based on different control objects determine the appropriate period of pest control is the role of biological pesticides object , for different types and characteristics of pests, biological pesticide use different methods. There are several different insect life, developmental stages , various developmental stages of different resistance to biocides . Therefore, understanding the developmental stage in which the pests , prevention and treatment is essential . For example, Pieris life can be divided into egg, larva, pupa and adult four developmental stages , egg in egg shells to protect , there pupa pupal stage protection, old larvae has a thick waxy layer of protection , while adults can winged flying. Therefore, only select young larvae make medicine. To give full play to the effect of biological pesticides .

Nicosulfuron injury remedies
Generally , the corn itself is strong resistance , nicosulfuron a slight phytotoxicity , without treatment, only temporarily inhibited growth of corn , can be restored after a period of time , does not affect the production.
If severe injury , need to be addressed , we can use the following measures:
Even detox in a smoke -ethyl injury has occurred or will occur , to take early measures to detox . On the initial injury on corn plants that can be used 3-5 times spray equipment wash water spray pesticide residues on plants .
2 strengthen field management ( 1 ) pouring enough water , prompting a lot of corn roots absorb water to reduce the concentration of the herbicide plant body , relieve injury.
( 2 ) appropriate to increase the depth and frequency of hoeing , enhance soil aeration , and promote beneficial soil microbial activity , accelerate the decomposition of soil nutrients , enhance maize root under water and nutrient absorption capacity, so as soon as possible to restore normal maize plants growth and development.
( 3 ) spraying large cloud -120 ( natural brassinolide ) diluted 1500 -fold or GA plus 1 % urea aqueous solution or spiritual harm , leaf treasure diluted 500 times in the morning or evening dew dry with low pressure sprayer to spray both sides of the blade , and promote normal growth of plants , in order to effectively reduce injury .
( 4 ) the injury occurred corn plots should be combined with water , increasing livestock manure composting facilities , ammonium bicarbonate , ammonium nitrate, urea and other fast-acting fertilizer to promote root development and regeneration , restoring victims corn physiology to reduce tobacco ethyl phytotoxicity to corn damage. But also foliar hand pump sprayers of 1% -2 % urea or 0.2 % -0.3 % potassium dihydrogen phosphate solution or Huimanfeng 60-800 times, resume normal growth favorable for corn .
Should also actively controlling other corn pests, in order to improve the ability of maize to resist injury . However, if the injury caused by the cornfields too heavy , these measures can not relieve victims extent, you can only take one or switching to other crops destroyed to avoid greater losses. Seven days before and after use can not be used organophosphate pesticides , dry weather , be sure to increase the amount of use , increased amount of detergent , washing powder is a good adhesion agent. First watering after application .

Paddy herbicide injury causes and treatment
The whole rice growth period , would suffer a variety of grass pest hazards, in order to reduce production losses , had to use pesticides to control pests , but in the course of medication , due to improper use , often resulting in injury , affecting the normal growth of rice , light who retired green leaves yellow , brown spots , banana leaf ; severe slow growth, plant death , causing output to fall. Injury caused yield losses sometimes more than the losses caused by pests is also large, and too much pesticide residue will affect human health.
In recent years, paddy herbicide injury caused by improper use of more and more , threatening the growth of rice , rice and even lead to death . According to recent years of field observations and refer to relevant reports and literature on paddy herbicide injury causes, diagnosis, prevention and remedial analyzed and discussed in order to provide the basis for the control of herbicide injury .
A herbicide injury causes
1.1 pesticides
1.1.1
Physical and chemical properties of pesticides . In general, the pesticide on crops have certain physiological effects , such as oil , powders and the like to plug the pores and cause leaf injury ; copper preparations , preparations such as arsenic , copper sulfate, calcium arsenate , sprayed on plant leaves , so that the agents penetrate the plant tissue and produce injury.
1.1.2
Pesticide quality . Use of poor quality, impurities or deterioration of pesticides , easy to cause injury, such as rice seedling Butachlor used as mixed with more impurities such as alachlor , rice seedlings can cause serious injury. Some improper storage of pesticides , storage for a long time , causing the EC layered , liquid precipitation, powder, wettable powder deliquescence caking , not only directly affect the efficacy , can lead to injury produce .
1.1.3
Mixture. Between pesticide mix properly, can also cause injury. Such as rice administered propanil control barnyardgrass not to hurt rice , because rice contains amide hydrolase biodegradable propanil , but propanil and dimethoate, carbaryl and other pesticides , the rice plants by the amide hydrolase inhibition , causing phytotoxicity to paddy rice .
1.1.4 solution concentration . Dose and the use of pesticides sprayed plants withstand concentrations exceed the standard , will hinder plant growth , resulting in injury and even kill the plant .
1.1.5 spraying times. Re-spray and even spray can also cause injury.
1.1.6 application methods . Application methods have a certain relationship with the injury , hand held sprayer such as rice using Butachlor when foliage spray applicator than the toxic soil mix prone to injury.
1.2 crops

According to recent years of field observations and refer to relevant reports and literature on paddy herbicide injury causes, diagnosis, prevention and remedial analyzed and discussed in order to provide the basis for the control of herbicide injury .
A herbicide injury causes
1.1 pesticides
1.1.1
Physical and chemical properties of pesticides . In general, the pesticide on crops have certain physiological effects , such as oil , powders and the like to plug the pores and cause leaf injury ; copper preparations , preparations such as arsenic , copper sulfate, calcium arsenate , sprayed on plant leaves , so that the agents penetrate the plant tissue and produce injury.
1.1.2
Pesticide quality . Use of poor quality, impurities or deterioration of pesticides , easy to cause injury, such as rice seedling Butachlor used as mixed with more impurities such as alachlor , rice seedlings can cause serious injury. Some improper storage of pesticides , storage for a long time , causing the EC layered , liquid precipitation, powder, wettable powder deliquescence caking , not only directly affect the efficacy , can lead to injury produce .
1.1.3
Mixture. Between pesticide mix properly, can also cause injury. Such as rice administered propanil control barnyardgrass not to hurt rice , because rice contains amide hydrolase biodegradable propanil , but propanil and dimethoate, carbaryl and other pesticides , the rice plants by the amide hydrolase inhibition , causing phytotoxicity to paddy rice .
1.1.4 solution concentration . Dose and the use of pesticides sprayed plants withstand concentrations exceed the standard , will hinder plant growth , resulting in injury and even kill the plant .
1.1.5 spraying times. Re-spray and even spray can also cause injury.
1.1.6 application methods . Application methods have a certain relationship with the injury , hand held sprayer such as rice using Butachlor when foliage spray applicator than the toxic soil mix prone to injury.
1.2 crops

How the injury occurred
Some friends of farmers in the field after the injury occurs first thought is whether the use of substandard counterfeit pesticides. Indeed, pharmaceutical chemical control is the foundation . To this end, we carefully select the purchase of medicines channels to promote and improve the ability to identify counterfeit pesticides . Actually, it 's the other reason phytotoxicity may be more important reason is the use of the problem . Whatever pesticides, has duality , like human medicine called " three-drug ." In pest control there is also the possibility of crop damage . After several experiments , as long as strict compliance , that is, to achieve symptomatic , timely and appropriate use will not appear on the injury . Generally herbicides, plant growth regulators less secure , must be extremely careful when using .
Summary In the course of medication often make mistakes , to the following few:
Bought the wrong the wrong agents, such as mistakenly MCPA sodium salt when nitrofen use , that they are common herbicides can ; worry ineffective, arbitrarily increase the dose ; dilution bad or knapsack sprayer spray evenly, resulting in local drug excessive ; improper use of , such as copper ion -sensitive peach, plum, apricot, persimmon , pear , cabbage using Bordeaux mixture ; or the use of herbicides in paddy water leakage sandy closed treatment ; or in windy day use of 2,4 - butylate , although in a wheat field spraying , but the wind drift into the adjacent liquid melon , soybean fields or forests , or on weak resistant flowering of spraying Pharmacy ; spraying equipment cleaning is not well, pharmaceutical residues cause injury , such as sprayed 2,4 - butylate no serious cleaning home garden sprayer spray , and then for melons, vegetables , bean fields.
In addition, special weather , soil , cultivation environment may lead to injury, should be avoided. Such as high temperature volatile trifluralin and EPTC and other agents for soil treatment ; when the soil temperature is below 15 ℃, use on soybean Acifluorfen . In addition , rainfall may be leached into the lower surface of Pharmacy crop roots and is absorbed deep irrigation or drought resistant crops may also reduce and increase the likelihood of occurrence of injury .

With a reasonable power to buy farm machinery
Power matching the power machine mainly refers to power and speed to meet the needs of mechanical support . Power is to describe how much mechanical work done per unit of time , expressed by kw ; speed is the rotational speed of the power machine shaft , commonly r / min expressed .knapsack power sprayer The size selection is based on the power machine power production machinery needs identified . If the power machine rated power selected too large, will increase investment costs , big horse cart wasting energy ; rated power if the power machine choose small, appeared with fixed or overloaded , damaged power machine , shortened life expectancy and even damage the power machine . Therefore, according to the actual needs of production machinery and working methods , through scientific calculations, in order to select the appropriate power machine power . For the province , generally small-scale farmers to choose the power machine , the selection according to the following criteria : If agricultural production machinery and the motor is a direct drive , the selected motor power should be dragged mechanical power of 1.0 to 1.1 times ; if agriculture machinery and motor is the result of belt drive , the selected motor power should be dragged mechanical power of 1.05 to 1.30 times ; engine supporting agricultural machinery should be equal to the power required 1.3 to 1.5 times. Optional powered farm machinery required speed as much as possible with the speed of the same or close , because it can be installed directly used agricultural machinery , because speed is inconsistent, in order to meet the requirements , you must refit the transmission equipment, fruit tree sprayers increase the number of charges .
If there are some agricultural households power equipment in advance , it should give full play to the role of existing power machine , in the purchase of new agricultural machinery , we should try to consider power machine capable of matching the original , except for special needs , in general, do not each machine is individually furnished one kind of power machine , so that it costs too much, management is not easy .

Particle size droplets of water mist fire-fighting capability and the relationship
A water mist extinguishing function is more complex, it is with the type of fuel, fuel quantity and the combustion speed and mist particle size and so on. Particle size droplets and mist extinguishing the relationship between the ability is quite complex, the general said,water power sprayer Ⅰ and Ⅱ mist liquid oil tanks used to fight the fire better, and do not stir the oil tanks liquid level.
2, under normal circumstances, it is difficult class Ⅰ Class A combustible mist off because class Ⅰ mist can not penetrate carbonized layer soaked burning material. However, if the spray rate is high, the surface combustion, or the closure has a greater degree of reduction in the case of oxygen, A class of fire was put out can Ⅰ type mist. This phenomenon shows that drop size distribution can not be determined only by water mist fire exterminate a given capacity. Can the fire was extinguished, depending on characteristics such as fuel, confined space effect, mist intensity and mist velocity (momentum) and other factors.
3, for a given protected object, the size of the droplet mist ability and suitability determination is not the sole basis, it also has a relationship with the flame garden sprayer backpack spray direction, mist intensity and speed of the jet

Weeds cause of relapse and Countermeasures
In the actual process of chemical weed control, there is a part of the plots is not completely dead grass, weeds recurrence. If the area is small, less weed, it can be considered a normal phenomenon. Because the weeding process will inevitably occur leak spray, light spray of the phenomenon, while in the weed communities will inevitably be part of the emergence of resistant weeds, chemical weed control is not 100 percent results. But if there is a large area of recurrence, they should pay attention to it. After years of observation the author concluded that the presence of weeds recurrence following reasons:
1, herbicides too quick result, only wheat as an example: if one is leaf tag azole grass herbicide, weed fast when weed is only slightly above the ground to kill the majority of blades, and miscellaneous dead grass and roots growing point, easy to relapse.
2, herbicide solution concentration is too high, also caused rapid killing blades, undead roots phenomenon.
3, too little water spraying, back pack sprayers uneven. Based on the investigation, at the same herbicide doses acres sprayed a bucket of water (about 15 kg), the recurrence rate than acres sprayed three buckets of water 20% higher.
Responses: 1, quick and slow-acting herbicide solution reasonable ratio problem. Such as: Tribenuron + Fluoroglycofen ether formulations, if Fluoroglycofen ether the amount of acres more than 20 ml (10% EC), the speed of 3-5 days dead grass, weeds on tribenuron absorption and conduction decline, weeds easy to relapse.
Therefore, we can control the dead grass in 7-10 days time, thus reducing the recurrence of weeds, proved tribenuron + Fluoroglycofen ether formulations to 10% tribenuron 12-15 g +10% Fluoroglycofen ether 8 ml is appropriate.
2, improve the quality of spraying, and strive to have, thoroughly. Spraying directly affects the quality of the herbicidal effect, require the use of manual manual sprayer spraying, mu liquid volume of not less than 30 kg, to ensure that no re-spray, spray does not leak.
