The use of pressure sprayer

1 to the correct installation of spray parts. Check the connection leaks, when in use, first install the water pressure sprayers  test, then pack medicament. 2 using the official, must first add agent after the water, liquid level can not exceed the safe water line. Pressure sprayer first before spraying, pulling the rocker of more than 10 times, make the barrel pressure increased to the working pressure. Pulling the rocker can not excessive force, so as to avoid the gas chamber explosion. 3 the first fill the liquid, due to the gas chamber and a spray rod containing water, backpack pressure sprayer  in the first 2 to 3 minutes of the ejected liquid concentration is low, so attention should be paid to fill spray, so as not to affect the pest control effect. The 4 work is completed, should be timely medicine is poured out residue pressure sprayer barrel, and washed with water down the stem, at the same time, check the gas chamber without water, such as water, to remove the water joint discharging water. 5 if a short Trigger Sprayer  of time without the use of a spray device, main parts should be clean, dry packed, stored in a cool and dry place. If it is not a long time, will all metal parts coated with butter, to prevent rust.

Pressure sprayer after cleaning and careless

Pressure sprayer should be cleaned immediately in the spray treatment, especially the use of highly toxic pesticides and herbicides, it will immediately machine barrel clean, otherwise produce pressure sprayers  to crops or vegetables will. Herbicide treatment long leaf plants, have treat leaved plants, and in the use process such as do not clean, alternative easily hurt by different types of plants. Therefore, pressure sprayer after cleaning and careless. The cleaning method: 1, herbicide 1 Shimizu Shirai. Herbicides such as star (tribenuron methyl), maize herbicide acetochlor and atrazine mixture, such as soybean, peanut, herbicides such as haloxyfop, paddy herbicides as hoe, Bentazon, in after, immediately wash with water bucket and parts for several times, and then the water filled with pressure sprayer for 2 - in 24 hours, then washed 2 - 3 times, can be assured use. (2) the mud cleaning: The G Wang Zong (commonly known as sweep away the light) in soil can be passivated, lose principle herbicidal activity, therefore after herbicide g without a trace, if immediately with water spray cleaning several times, then rinse. (3) the ferrous sulfate: Herbicide, only 2, 4 - D the most difficult cleaning. In spray the herbicide, need 0.5 ferrous sulphate solution fully wash. 2, pesticide (1) general pesticide use, repeated washing with water, upside down to dry. (2) for pesticide toxicity, with available water repeated washing, inverted.

Rational use of pesticides and precautions

Rational use of pesticides should be safe, effective, economical , namely pesticides in mastering performance , based on the scientific use , give full play to its efficacy, it is both effective insect pest control , but also ensure to livestock , crops and other beneficial organisms security . Rational use of pesticides , should pay attention to grasp the following principles :

1 , the right medicine , a clear control object . Select pesticides , to clarify the physiological mechanism of control object characteristics and hazards , as well as varieties of crops , such as reproductive period , field varied kinds of pests that occur every kind of different agents reactions are different, even the same different types of populations are very different . After the control object in the clear , and then select the appropriate pesticides . For example , control borer , available Bataan , pyrantel pamoate , furosemide feeding Dan .

2 , improve pest surveys , grasp the key period of bottle sprayer spraying. Carefully before applying for pest surveys , master control period , the best control during spraying. Otherwise spraying prematurely , efficacy period does not coincide with pest control , would not achieve the role of damage control . Spraying late effect is poor, not only would not achieve the control effect and cause pesticide waste. Therefore , spraying should take a good "heat ", select pests weaknesses or sensitive period of pesticides , insecticides should have in general to 3rd instar larvae hatching before fungicides currently in use , mostly to protect nature, the treatment less effective. Therefore, disease prevention and control , should be before the onset or early onset of drug use, if you wait until then hand sprayers spraying disease has been popular , it is difficult to achieve good control effect.

3, can not arbitrarily increase the dosage or an increase in drug concentration . Many farmers mistakenly believe that increasing the dosage or an increase in drug concentration control efficiency will increase , therefore, does not follow the instructions above to increase the dosage requirement is widespread . In addition, farmers in the dispensary is not measuring, only random amount of the cap , the lack of numerical concepts , resulting in greatly excessive use of drugs , do not only wasteful , but also prone to injury. Environment has been seriously polluted , endangering human and animal safety .

Castor in organic vegetable production application

Castor plant organs contain ricinine . There ricinine paralytic poisoning the insects produce pharmacological effects .low pressure sprayer Tanabe farm in northern China , often planted around their houses to a large number of castor lightly .

Castor leaves : castor leaf water ( leaf water ratio : 1:8 fresh leaves , dry leaves 1:50 ) and cook for 1 hour, filtered to the residue , add a small amount of soap, can Pensha caterpillar and so on.

Castor Seeds : Castor seed pounded with water ( kind of water ratio of 1:1 ) stir well , then pour a small amount of soapy water , and diluted with water to 100-150 times, can Pensha gold shells and a variety of vegetables aphids.

Castor oil cakes : castor oil cakes plus water plus soap ( ratio of 1:5:0.1 ) , impregnated , soap to the open,chemical sprayer filtered to the residue , can Pensha chafers and various vegetables aphids.

Castor Straw : The castor leaves, stalks , roots and dried crushed to 50kg per acre amount into the soil , you can control grubs hazards.

To de-worming medication safety counterpart flowers

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 , 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 ) ; farm sprayer 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. Contact toxicity of insecticides such as malathion , phoxim , cypermethrin ,home garden sprayer 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 .

Water mist application conditions and requirements

A water mist extinguishing system should be refillable water containers clean and fresh water. (Commonly used industrial distilled or treated potable water)

2, the protection zone structure and the doors and windows of the fire resistance of not less than 0.50h, the ceiling of the fire resistance of not less than 0.25h. (This is to prevent the spread of fire outside the protection zone into the protection zone, thus requiring the protection zone of the wall and the doors and windows should have some fire resistance. While requiring the issuance of extinguishing fire to a period of time, building components will not be damage to ensure airtight protection zone, does not cause loss of extinguishing agent, affecting fire effect.)

3, before the start of water mist fire suppression system and the set fan, smoke machines, blowers and pipeline fire damper, smoke damper should be closed automatically. Staff confirmed after the fire should start the smoke machine smoke. (This is because to a protected area being ventilated water mist extinguishing agent release, fire extinguishing agent as soon exhaust air outflow protection zone, the protection zone to reach the design requirements of fire extinguishing agent, seriously affecting the extinguishing effect; another , fire protection zone may also spread through the air duct.)

4, water sprayer mist extinguishing system, you must cut off the fuel, combustion gases of the gas source. (This is to prevent fire expand, to prevent dilution agent discharge strength, impact extinguishing effect.)

5, the nozzle head and nozzle bottle plastic sprayer spray angle between the object of protection should not be within the scope of obstructions. (This is because the memory in the range of the jet nozzle obstruction, will seriously affect the jet effect, which affects the extinguishing effect.)

6, the protection zone should be used doors fire doors open in the direction to evacuate, and can automatically shut down. (This is to prevent the door open in case of emergency, the impact of evacuation. While requiring evacuation door can be automatically shut down, in order to facilitate the protection zone of water mist fire extinguishing water to maintain a certain strength to prevent the loss of extinguishing agent, impact extinguishing effect can be avoided for some reason the person trapped in the protection zone, from the protection zone to open the door smoothly evacuated. protection zone automatic closing doors design, emphasizing when the door is closed, on how circumstances can open from inside the protection zone.)

7, water mist fire extinguishing system equipment should be set at an ambient temperature 4-50 ℃ dedicated equipment room. (This is because the temperature is too low, the water will freeze, the temperature is too high in the tank water temperature, resulting in vaporization and heat exchange, and may have a scale affect water quality. Settings in a dedicated room is to make the fire-extinguishing system equipment to avoid being the impact of adverse weather conditions or subjected to other mechanical damage. while allowing staff to manage and maintain.)

Door routine maintenance tips

A protective film removed, the door being in an outdoor environment, dust, oil and other pollutants as attached to the door, so that the door fresh fade lose brightness, the user is cleaned once every certain period, cleaning methods, with the 70% water 30% of the cleaning fluid mixed into the garden sprayers, spray evenly on the surface of the door, gently wipe with a soft cloth.

1, when the door switch with metal friction sound, the door hinge on a few drops of oil or directly to find a professional repairman.

2, when the door is closed when the resistance is too large, you can place the active tongue coated with a little oil.

3, when faced with a key to open the door can not be fully inserted into the keyhole, the winter, first check whether the icing keyhole, keyhole other seasons check whether there are other foreign matter. And timely notice to us.

Second, security door care and maintenance

Security doors as daily necessities,manual sprayer maintenance and maintenance is very important.

One should seriously filling cement. On the one hand the effective combination of the frame and the wall; the other hand, the door and the door frame to maintain a reasonable fit, long-term use of the same type.

2, the alpine region in the country before the coming winter, winter preparation is very important.

a, large indoor and outdoor temperature, hot or cold air convection, makes the cylinder damp. Therefore may be appropriate before the winter frost drops on oil, then drops some past winter gasoline cleaning. Avoid not use vegetable oil as a lubricant.

b, in the normal state, the discovery is not flexible cylinder open, the end of a small amount of a pencil into the drinking straw, the alignment of the lock cylinder, the lock cylinder gently blown, so that lubrication can be maintained.

c, if found closed strenuous, generally is a small bolt with a beveled moisture, resulting in a rust easy to see with the naked eye, you can fine-Shabu Sha look, or put a little pencil at the end can be easily solved.

Tobacco scientific use of pesticides

Pesticides on the development of human civilization, agriculture has played an important role, especially in controlling risk, when the outbreak of pests and diseases, pesticides also show an irreplaceable role. However, in the course of pesticides on the air, soil and water will cause a certain degree of pollution, which requires scientific use of pesticides, with the least amount of the most effective pest control for maximum economic, social, ecological and environmental benefits.

In view of the status of tobacco production, the State Tobacco Monopoly Bureau, Science and Technology Education proposed the development of "pollution-free tobacco" new ideas, backpack weed sprayers relying on science and technology can make use of the use of pesticides near or at the effects of pollution. Despite the development of biological pesticides now in full swing, but it is widely used in the tobacco need to take time.
LD50 (ld50)

LD50 is the result of a biological experiment death of the individual populations of 50% of the dose. According to China Pesticide Toxicology grading standards, rat oral: ld50 <5mg/kg are highly toxic pesticides, such as "aldicarb" original drug ld50 of 1.0mg / kg; ld50 is 5 ~ 50mg/kg is a highly toxic pesticides such as "omethoate" original drug ld50 is 47mg/kg; ld50 of 50 ~ 500mg/kg belong moderately toxic pesticides, such as "fenvalerate" original drug ld50 is 451mg/kg; ld50> 500mg/kg belong toxicity pesticides, such as "In addition to bud through" the original drug ld50 of 1250mg / kg; ld50> 2000mg/kg are practically non toxic pesticides, such as pest control tobacco warehouse "insurable special" original drug ld50 is 34600mg/kg. ld50 reflect pesticides on the environment or the degree of harm to humans and animals by improving the formulation processing technology, can achieve low toxicity of highly toxic pesticides, toxic pesticide poisoning micro. Such as "decis" the active ingredient is "deltamethrin", "deltamethrin" original drug ld50 is 138.7mg/kg, belonging to moderately toxic, processed into 2.5% EC ("decis") After, ld50 is 535mg/kg, belonging to low toxicity pesticides. "Aldicarb" original drug is very poisonous, but commonly used to control aphids Tobacco 15% "iron aldicarb" granules (ld50 is 10.6mg/kg) is highly toxic.

Half-life (dt1 / 2)

Pesticide degradation half-life is a measure of the degree of difficulty of the targets. It reflects the pesticide sustained effect on pest control and pesticide residues levels. agricultural sprayer Long half-life of the pesticide persistence length to pests and diseases, can in a very long time to maintain the role of harmful organisms performance, but it is also the source of pesticide residue formation. dt1 / 2 <3 months of easily degradable pesticides; dt1 / 2 of 3 to 12 months for the middle of pesticide residues; dt1 / 2> 12 months for the long pesticide residues. Early use of arsenic, lead and mercury preparations half-life of 10 to 30 years; half-life of organochlorine pesticides in 2 to 4 years, the half-life of organophosphorus pesticides are generally a few weeks to a few months ("phoxim" The half-life in soil is 34d), carbamate pesticides generally only a half-life of ~ 4 weeks ("aldicarb" In the half-life of fresh tobacco 14.4d), pyrethroids, sprouting products and herbicides half-life of a few days ("deltamethrin" In the half-life of fresh tobacco 2.1 ~ 4.2d; "In addition to bud through" in the half-life of fresh tobacco 2 ~ 4d; Napropamide in the half-life of fresh tobacco 3 ~ 4d).

Three whisk microemulsion Applied Technology

Leafroller is the province most important pest of rice every year from June to August of rice caused great harm; common efficient, highly toxic pesticide methamidophos, has recently been a nationwide ban on the sale and use of select efficient, low-cost pesticides is a priority. Fipronil (fipronil) is replaced by the ideal pesticide methamidophos control leaf roller one, but higher prices alone, long-term high-dose continuous use, easy to produce pest resistant. Three whisk microemulsion is a low content of fipronil and triazophos complex products, the two drugs after complex, with significant synergies and fipronil than single low cost. The relevant application technology are described below:

First, the product features. 31% three whisk microemulsion in Zhejiang, Anhui, Jiangxi, Jiangsu, Hunan, Hubei, Shanghai and other places large scale applications. Leaf Roller prevention trials, demonstration that not only young leaffolder have a good effect, but also serious damage roll bud 3-4 age leafroller control effect prominent, anti-efficiency of up to 90 % or more. The product is microemulsion, it also has strong adhesion, can firmly adhered to the blade solution, can greatly improve the utilization rate of pesticide active ingredients, to reduce the impact of pesticides on the environment.

Second, the use. 1, leaf roller is migratory pests, master control period is the key. Young larvae should generally be in the peak of the volume beginning bud worm medication. 2 per acre with 50-60 ml water 30-50 kg, with mist sprayer or motorized machine Rice Leaf fine backpack weed sprayers spray, the better.

Third, pay attention: 1, not with alkaline pesticides, fertilizer mix. 2, highly toxic to bees, do not close beekeeping honey paddy fields, orchards, vegetable and non-registered use on nectar plants. 3, the product of shrimp, crabs and some fish, highly toxic, non-field water discharged into the rivers, lakes, canals and ponds and other water sources. Sugar cane, corn, sorghum sensitive strictly prohibited. 4, the product is organic phosphorus compound preparations. If ingested poisoning should be immediately sent to hospital for medical treatment, gastric lavage can also be inserted into the tube, there can be symptoms of organophosphate poisoning antidote atropine, phenobarbital, drugs can relieve symptoms of Fipronil.

Anti-pest sprayer usually ground maintenance more convenient emergency

Every spring is a variety of crop pests and diseases and prevention peak, also spray application equipment such as periods of high frequency of use. pressure sprayers its structure is simple, easy to use, inexpensive, is widely used in many rural farmers, an important plant protection equipment. At a time when wheat, spring oilseed rape pest control supplies and equipment preparation stage, but some friends of farmers usually focus only on equipment use, pay attention to maintenance, to use the time often confused, resulting in the use of the actual operation generated a lot of inconvenience. Now use the sprayer maintenance and troubleshooting methods outlined below:

First, the use of maintenance

1, using the sprayer should be checked for leaks at the connections, first install water spray test and then install agents for spray.

2, add the liquid, the liquid can not exceed safe water line. Rocker panels before spraying move more than 10 times, so that the barrel pressure up to operating pressure. Note plates move joystick can not be too hard to avoid the gas chamber explosion.

3, the fruit tree sprayers job is completed, should be promptly poured barrel residual liquid, then rinse upside down to dry; also check the gas chamber without water, if water, remove the water outlet connector release.

4, the short term is no longer used, should the main components of clean, dry bottles in a cool dry place; when unused for long periods, pay attention to the various metal parts coated with grease to prevent rust.

The principle and construction of electric sprayer

How to make electric pressure sprayers  operating principles and structure by which parts components has been a part of people's questions concern the electric sprayer. This article briefly discusses electric sprayer under the working principle and structure.
Electric liquid sprayer  liquid from the storage barrels through the filter, coupling head, suction, connecting tubes, nozzles, nozzle connected in turn communicates composition, suction is a small electric pump which is electrically via electrical connection with the battery and switch, battery box mounted on top of the liquid storage drum, liquid sink barrel can be formed with the loading of the battery recess, of lines of the electric point of blooming due to the cancellation of the suction suction tube, thus effectively eliminating the pesticide outside the filter Damage operator's ills, and effort, and the electric pump pressure than people manually suction tube pressure, increasing the spray distance and range.

How Andrew jet efficacious

Electric sprayer injection drugs in order to give full play to the efficiency of Bian Jing, injection techniques must be mastered. Be careful when playing in the jet, although alive, so that all crops can be sprayed into the syrup evenly, not missing a crop, nor make potions eight crop leaf upper Bian. Root crops must bear up different height, different scales using the spraying method.
Low crop also can use the following method: single jet Cup chaos immediately when the spray jet spray America apartment l crop leaves 8 a 12 inch, uniformly along _L guess crop spraying. _L Lost slightly to the jet slowly turned from the dorsal leaf and spray, so can be sprayed onto the foliage dorsal.
2 cups suspended suspended spray lance (Figure 7) is to reflect a greater number of bites in a paper mounted t long spray lance, 'put it hanging on the rack _I:, get bigger jet while, Mara jet nebulizer is this line, because when the wind force fog! not be evenly spraying on crops, rain and dew did not dry mist sprayed on plants _L fish easily fall, carved by water to dilute drugs, reducing insecticidal efficiency. The most appropriate time should be in the morning dew has dried and evening, the sun at noon mountain strong; jet imitation burn easily after the crop from injury. backpack chemical sprayers
Second, when the rose flower, not suitable for post shot, to avoid harm imitation flowers; or miscellaneous insects that spread pollen poisoning deaths, crop IMPACT Fun and junction with the grant.
Third, pest medicine Jing, in general toxicity, especially organophosphate poisoning, such as 1605 and 1059 the maximum twist, be especially careful, when used, should wear a mask to the sleeve, tie the legs should, wear ear sets. United States Department of wrap, wear goggles. After spraying drug use It}! Wash hands.
Fourth, the application of new drugs Jing organophosphorus Ift fruit shoot when the ban. LL overhaul work in some hair spray America 'I state tendons failure. Will head cleaning spray America and then the United States, must be one of the pump without Wang Shito fl: a "before repair, Wang Li keep accurate gauge, always careful to check. How troubleshooting · Xiang
Failure to timely public health sprayer repair, J always finished to ensure a female J. account shall be opened up). Then loaded onto tubes and dusting of powder. Such as spray two rows on the ash dusting lost, then put braces back, with his left hand holding his right hand cranks powder tube to breathe once again cranking speed, crank shake the handle, VN wind forward spray, spray speed, depending on the crop situation to mention how Cheung, long tall crops will be slower; dwarf would be faster. To make the leaves evenly on both powder stains.
Use dry powder, the powder tide N, not spray evenly. In the early morning dew dusting at around 5 pm or conduct, then, easy meal powder kept in crops. In windy or raining, do not spray. Avoid being washed clean. When spraying, to wear masks and goggles, wash with soap after spraying and hand. Duster used up inside of blood carefully remove the remnants of the powder, and the powder tube, powder and other losses and straps removed, along with parts mounted on the box, so lost. Duster stand placed in dry place to prevent the sharp broken or chipped. professional backpack sprayer
