Note the use of pesticides during the rainy season
In agricultural production, often encounter spring rains, autumn constantly and the rainy season, to prevent and pest control work inconvenience. Often hear some farmers reflect poor rainy season spraying pest prevention. The rainy season is the high incidence of pests and diseases, pesticide control must master the technology in order to improve the control effect. To enhance the effect of pesticides during the rainy season, the farmers when hand pump sprayers spraying friends 5:00 to note the following:
First, pay attention to watch the weather, timing clever spraying. In general, the rain is better than spraying spraying spraying after rain or side edge rain. Therefore, we should pay attention to weather conditions, make choice of a good weather periods spraying in order to improve control effect. In addition, the law should be based on the activities of pest spraying clever selection of time, such as some of the nocturnal pests such as leaf roller should be sprayed in the evening.
Second, select the appropriate drug. The absorption of the rainy season use, fast-acting, anti-rain and microbial pesticide effect.
Fast-acting pesticides. Such as insecticides dichlorvos speed kill small, monocrotophos, fenitrothion, decis, Kuaishaling, metolcarb, deltamethrin and other pesticides, which has strong contact and fumigation, Shi 1 to 2 hours after drug or 4 to 5 hours after that they can kill the pests.
The absorption of pesticides. The absorption of pesticides by crop roots, stems, leaves and other parts of the body into the plant and transported to other parts of the work in a shorter period of time. Such as carbendazim, triadimefon, leaf blight net, triadimefon, thiophanate, hand held sprayer Miebing Granville, monocrotophos, carbofuran, methamidophos, dimethoate, omethoate, phosphorus amine sterilization insecticides, after application 4 to 5 hours will have 80% of the active ingredient to be absorbed by crops within the organization, and less leaching and loss of potency due to rain.
Microbial activity pesticides. Commonly used BT-781, caterpillar fungus, Beauveria bassiana and other microbial pesticides, in high humidity conditions more favorable to its spores germination and reproduction, rainy day application of these pesticides, pest control more fully play its role.
Rinse pesticide resistance. Fungicides and Miebing Jinggangmycin Granville, procymidone, etc. has good resistance to rain resistance, pesticide 1-5 hours after the showers even in the face, it will not affect the efficacy of the brush being poured.

Glyphosate and sethoxydim phytotoxicity pyridine
Glyphosate ( Roundup )
( A ) the cause of the injury . With herbicides stem, leaf processing , corn sensitive to glyphosate , facilities or liquid fall into the mistake of corn plants will produce injury.
( Two ) phytotoxicity symptoms. With herbicides stems, leaves treatment , injury symptoms appear slowly, the drug leaves first appear water-soaked , leaf curl inward , growth was seriously inhibited. Tip , leaf margin wilting , and some plant whole plant slowly withered.
( Three ) injury prevention and mitigation measures . Facilities and to avoid misuse of liquid falling into cornfield. Since the injury develops slowly , need tens of days to be observed Simiao . Therefore , the occurrence of the injury as soon as possible under the circumstances may a drug measures . If the amount of pesticide per hectare more than 600 grams , garden hand sprayers you should consider destroying species .
Sethoxydim pyridine ( Arrest net )
( A ) the cause of the injury . With herbicides stem, leaf processing , corn sethoxydim pyridine sensitive , mistakenly applied or adjacent land administration sethoxydim pyridine , droplet falling into corn plants can produce injury.
( Two ) phytotoxicity symptoms. With herbicides stems, leaves treatment, contact with the liquid leaves produce chlorotic spots, chlorotic new leaves start from the base , and gradually extended to the entire leaf , leaves become yellow , brown or purple , and gradually dry up . Severe growth point wither , whole plant death , inhibited the growth of light .
( Three ) injury prevention and mitigation measures . Sethoxydim pyridine can not be used cornfield. Neighboring plots applied sethoxydim pyridine should allow sufficient isolation belt, pay attention to wind direction and speed when spraying , to prevent the liquid float moves cornfield. Once mistakenly water power sprayer sprayed serious harm , or damage should be promptly replant seed .

Alachlor and acetochlor cause injury case
Alachlor
And Ming Lasuo in acid and alkaline hydrolysis conditions . Allow corn residues
0.05%. The eyes and skin have a strong stimulating effect. Commercially available 43% and 48% EC and 10%, 15 % of the granules. Alachlor is a selective preemergence herbicide use may control annual grass weeds and certain broadleaf weeds. Cornfield after sowing or planting weeds sprout after premedication , 43% EC 175 to 300 grams per acre , watered 50 to 60 kg , evenly backpack garden sprayers spray in topsoil ( arid regions after drug shallow soil mixing 2 to 4 cm ) . If splashed into the eyes and skin , rinse immediately with water and seek medical advice as soon as possible , if swallowed, should be immediately sent to hospital , induce vomiting or gastric lavage with 5% sodium bicarbonate solution .
Acetochlor
Acetochlor and alachlor belong acid herbicides , mild eye and skin irritation . Preparations are 43% and
50% of the EC. Is a selective preemergence herbicide acetochlor dry land , in the soil and lasts eight weeks or more, a pesticide can control the entire growth period without weeds . Can control annual grassy weeds, but perennial weeds invalid. Weeds on the main absorption site is acetochlor coleoptile must therefore be applied in pre-emergence weed . Per acre with 50 % of the EC 50 to 70 g of soil humidity of the southern upland acre with 30 to 60 grams per acre upland Northeast
130 grams , add water, 40 to 60 kg , in after sowing before tree sprayer spraying. Cucumber , rice, spinach , wheat, leek , millet, sorghum and other crops on acetochlor sensitive and should not be used .

Poor ten reasons pesticide efficacy
Medication timing allowed to grasp . Be sure to seize the opportunity to fight drugs , only to understand what happened pests law , timely medication, order Qin effect.
Improper application methods . Field occurrence of pests , hazards, and perched on crops have a hazard area, this particular site is that pesticides should hit the target . Not hit the target , pesticide control effect backward .
Increased resistance to pests . Pathogen and pest resistance to pesticides is today hampered play its control effect of pesticides and the potential effectiveness of reality.
Do not understand technology , control object is not clear. When the insects to fight disease , when the disease to kill insects , grass and insects in addition to do , this is primarily diagnostic error , discriminant unclear , leading to medication errors , prevent the poor and even injury.
Spraying liquid wastage . Currently widely used in rural spraying equipment, labor intensive , waste, coarse grain fog , anti- poor efficiency . This sprayers mist particles , poor adhesion , deposition rate, liquid dripping in the soil , the loss in the waters , not only wasted a liquid, but also seriously pollute the environment.
Control effect of pesticides own limitations . Some pesticides on some pest has good control effect, but for others powerless pest control effect is poor.
Application time is not a good grasp . Insect activity dominated by the law of alternating day and night , but also has its own " biological clock ." Therefore, we should grasp the pest activity patterns , in the day , respectively, at different times , targeted sprayer spraying on time in order to achieve the best results.
Weather conditions set . Different meteorological conditions are closely related with the control effects of pesticides . Different temperature , humidity, light , wind , Teenage etc. on pest occurrence , activity patterns and control effect has an impact. Large liquid wind drift , disperse , affecting control effect. Applying EC formulations of pesticides , spraying requires no rain within 24 hours .
Predators reduced. Since a large number of successive application of highly toxic , high residue pesticides, natural enemies of pests were greatly killing , the destruction of the ecological balance , portable power sprayer resulting in pest resurgence , forming a vicious cycle.
Water quality against the drug causes. Water has hard and soft water of the points. Well water , mine water, some mountain springs are mostly hard water , dilute pesticide poor results, due to contain minerals that will decompose pesticide active ingredients ; while ponds , rivers , streams , mostly water softener , mineral content, dilution effect of pesticides , but these ponds , rivers such as very muddy , will also affect the efficacy of the play .

Spraying pesticides job the right way
Significantly increased over recent years, crop pests , pesticide use increased , many farmers in field operations has formed a fixed manner . But from a scientific point of view, farmers knapsack power sprayer spraying pesticides , there are still some errors:
First, the front of the body , " the" word swinging spray. Disadvantage is that the front spraying , people in the drug environment sprayed forward , likely to cause pesticide poisoning. Further , when spraying herbicide closed , easy uniform spray , artificial membrane damage after treading to reduce the control effect . Sprayer should be changed right in front of " the" word of swing sideways " s" word swing. Motorized spraying and spraying herbicides should be taken parallel advance spray.
Second, the large droplet spray. Make spray uneven , particularly those affecting tag insecticide control effect. Large liquid droplet spray is also easy to cause the loss of plants low , the waste is more serious , you should try to use a good spray atomization performance , the use of spray holes tablets , a small droplet spray evenly .
Third, the jet " target " crops. Direct spray sprayer can be used generally , and motorized sprayer to mist type , direct spray will greatly reduce the work efficiency, can not be fully motorized sprayer good atomization characteristics of high efficiency . Sprayer job the right way should be 20 cm above the crop , spray drift downwind implementation .
Fourth, the liquid bottle sprayer sprayed from dripping on the extent of the blade . According to scientific determination of liquid drops on the leaves , the liquid precipitation was only 50% of the maximum amount of precipitation can not maximize the efficacy and caused a lot of pesticide waste. It should be evenly sprayed , try not to have liquid dripping .

Security is very important spraying of pesticides
Application personnel should be physically healthy , trained , with a certain plant protection knowledge . Elderly, infirm people, children and pregnant and lactating women can not spraying. Spraying must note the following:
To check whether a pesticide Yaoxie intact . Do not spray the liquid overfill to prevent liquid spills, contaminated skin and protective clothing ; spraying spaces shall be provided with sufficient water , cleaning agents, first aid kit , repair tools.
Second, we must wear protective equipment . Such as gloves , masks and protective clothing to prevent pesticide into the eyes , on skin or suck the human body. After spraying , you should immediately take off protective equipment , load pre-prepared plastic bag. Back immediately after washing 2 to 3 times , dry storage.
Third, we must pay attention to safety when irrigation sprayer spraying . Rain, windy weather , with temperatures not spraying ; should always upwind spraying, do not wind spraying ; spraying will be prohibited eating, drinking , smoking ; Do not mouth to blow clogged nozzles , application toothpick , straw or water to clear .
Annual herbicide 2-4D butyl drift caused huge losses to agriculture and forestry , according to the survey , hundreds of acres of forest acreage , especially victims of the most serious locust street , there are a few acres of fruit loss , mainly on the grape the greatest impact .
Fourth, we should grasp the poisoning first aid knowledge . Such as pesticides splashed into the eyes or on the skin , promptly flush with water ; such as headache, nausea , vomiting and other symptoms , should immediately stop work , take off contaminated clothing , carrying pesticide labels to the nearest hospital.
Fifth, we must correct cleaning application equipment . Equipments spraying should be washed after each use , not in rivers, streams ,garden sprayer backpack flush the well to prevent water pollution . Pesticide packaging waste is strictly prohibited as it used to, can not throw , to concentrate stored , handled properly. After spraying herbicide particular attention must be cleaned to avoid injury. Best to have a dedicated spray herbicides .
