As temperatures steady rise, wheat variety of pests, especially to accelerate the development of stripe rust, heavier, prevention and control work has entered a critical period. According to the site and local surveys, wheat stripe rust in mid-December last year, has begun to see in late disease, see the disease early time, degree of emphasis are no past two decades; currently Shen Tan Tan Xiang Zhang Wan Fang The earliest point Kawamura see disease has spread to the whole field and the surrounding fields, more than 60% disease Tian, ill fields diseased leaves rate of 7 - 24%, the local strain rate of 100% (see below photo); recent The temperature and humidity are on stripe rust expansion and spread very favorable, and has begun to enter Sheng epidemic; back sprayers Part Catcher spider, sheath blight, powdery mildew, also has heavier occurred among the one hundred local spider insects of up to 6,000 or more, the amount of 50 single leaf insects more than the amount of 120 insects per plant or more. Therefore, improving the current wheat pest control work is to ensure that the harvest of wheat yield important part localities must seize, grasp, prevention and treatment. Now the main pest control techniques as outlined below:
A, control time
1, wheat stripe rust, powdery mildew: In late March, the first pass drug must be administered, the incidence of heavy plots, in April, the middle and then spraying 1 - 2 times.
2, wheat sheath blight: strain rate of more than 10% of the plots should be timely drug prevention and treatment, the incidence of severe plots interval 7-10 days and then spraying 1 - 2 times.
3, wheat spider: the amount of one hundred insects over 500 plots to drug prevention and treatment.
Second, the control methods
1, wheat stripe rust, powdery mildew: mu 15% triadimefon WP 100 g (2 2), or 20% triadimefon EC 60 ml, 12.5% diniconazole (Wo fruit Lee) 60-80 g , manual sprayers watered 60 kg, 15 kg watered motorized sprayer spray.
2, wheat sheath blight: mu 5,000,000 units Jinggangmycin 50 grams, manual sprayers watered 50 kg, 15 kg watered motorized farm sprayer spray.

Catfish fish rice farming pesticide application methods to properly
Depending on the circumstances , selective spraying using the following method .
( 1 ) Sham spraying method
In the fish before the first application of pesticides in paddy field water deepened, flooded field surface 7 to 10 cm , such as a larger concentration of pesticides can be further deepened some of the fields of water , diluting the concentration of the liquid in the water , reducing or avoiding fish hazards. With a pore size bottle sprayer, sprinklers should upward sweep of rice stems and leaves, try spraying the drug in the rice leaf surface , reducing pesticide falling into the water field .
( 2 ) Drainage spraying method
Water off the field before treatment , exposing the soil surface , so that the fish concentrated in fish ditch, the fish slipped , and then spraying pesticides attention can not be applied into the ditch fish , the fish slipped in . Tanaka toxicity of pesticides to be degraded , and then further to the normal water depth of field .
( 3 ) The next sub- spraying method
First half a field or fields in a certain part to fight drugs , fish can not escape to another part of Tanaka fight drugs , the next day and then in another part of the Tanaka spraying.
( 4 ) water spraying method
Pesticides can also be applied to the inlet and outlet open, so that the water flow field , starting with the outlet of a pesticide , applied to the fields intermediate pause, to make contaminated water out of the field , and then applied to the intake from the middle at the end .
( 5 ) timing spraying method
Use powder pesticide manual sprayer spraying in the morning , because the morning Inaba , rice straw on the dew, most adherent powder , thereby reducing pesticide into the water . Use liquid, emulsion pesticides should be applied after the 16:00 ; summer temperatures should be in the 17 o'clock after spraying, reduce pesticide toxicity to fish . Do not raining or rain before spraying pesticides or pesticide will be washed into the water field , easily lead to fish poisoning.
Pay close attention to fish after spraying activities , such as found with symptoms of poisoning , you must immediately add new water , the best part of the discharge side of infusion of new waterside field water dilution water concentration to avoid fish poisoning .

When using herbicides influence of temperature on the efficacy of
When using herbicides influence of temperature on efficacy , generally only postpone or advance the efficacy of play time . If the temperature is low , due to the physiological activity of weeds is also relatively slow , and thus the conductivity also slow the absorption of herbicides , such as winter or spring, and thus the efficacy of performance when backpack weed sprayers spraying time , and compared to the hot summer months , generally extending 5 10 days or even longer. This is why the temperature is low more than 10 days after the use of herbicides , the weeds are not symptoms of poisoning. Currently on the influence of temperature on herbicide roughly as follows: the temperature is below 10 degrees Celsius, most of the herbicide efficacy is difficult to play, as the temperature gradually increased gradually shown efficacy, if prolonged continuous low temperature , herbicides lose part of the effect will be weathered ; 10 degrees Celsius, most of the herbicide can show herbicidal effect , but higher than under normal circumstances, be delayed 5-10 or so ; 15 degrees Celsius, herbicide efficacy normal play ; 15-35 degrees Celsius between efficacy with increasing temperature performance faster. But not the higher the temperature the better.
And herbicides for families and genera close to target plants lawn grass, under any circumstances do not arbitrarily increase the dosage , or carried out under the guidance of technicians spraying . Grasses such as Kentucky bluegrass lawns in using consumer bluegrass, miscellaneous consumer controlling crabgrass, goose grass and other weeds ; using clover in clover music broadleaf weeds ; lawn in Golden Horseshoe Horseshoe Net Control in use broadleaf weeds , etc., are not arbitrarily increase the dosage.
For more emaciated weeds , leaves small, upright weeds , control method can be used when spraying twice . As used in bluegrass lawns eliminate Wo controlling weeds crabgrass, the dosage is 90 ml per acre , you need to be watered 25-30 kg evenly spraying . We can eliminate the first use of 45 ml Wo watered 25-30 kg spraying a mu of land, the next day using 45 ml elimination Wo watered 25-30 kg spraying a mu of land, is better than a sufficient amount of perfume sprayer spraying the herbicidal effect .

Three Principles of the winter mixed pesticide
Winter indoor studio disease -prone , spraying more often, many farmers to reduce the frequency of spraying , reduce labor intensity , each spraying pesticides are mixed . Pesticide many species prone to problems when mixed , require special attention.
First, in order to accurately mixed pesticides . Fertilizer and pesticide mixtures in order: fertilizer, wettable powders, suspensions , liquid , cream then added , each adding a stir that mix, then add the next .
Two is to add water after dosing, the secondary dilution. Mixed , you can add the first half bucket of water in the v , add after the first pesticide mix. Then, the rest of the pesticide by a plastic bottle be diluted , diluted and poured into a sprayer , mix , and so on.
Third, use spray immediately after dispensing . In many cases, farmers generally will be at home with a good agent , and then transported to shed trigger sprayers spraying, when many agents have prepared several hours . Although just with the liquid does not respond when it does not mean you can be set free for a long time , or prone to react slowly , gradually reduce the efficacy .
In addition , farmers do not know when the pesticide can not be mixed , best first test a small area . Not only depends on the preparation when there is no response , but also to spend will not cause injury.

Greenhouse vegetable pesticide application to be especially careful
Application of pesticides talk about science, especially in winter greenhouse vegetable pesticide application especially. Otherwise, not only fail to control effect, but also prone to injury. Therefore, the application of pesticides to pay attention to ten bogey.
A pesticide preparation hanged because running water running water impurities, with its easy to plug the low pressure sprayer dispensing nozzle, while also undermine the liquid suspension to produce precipitation.
Two hanged formulated pesticides because well water well water contains minerals more, especially calcium, magnesium and more. These minerals are mixed with the liquid chemical is easy to produce, reduce the efficacy precipitate formed.
Three bogey any excess water will increase the amount of water to reduce the concentration of pesticides. Sprayed on crops, leaving only a very small amount of pesticides, not enough to kill pests, and some pesticides even completely ineffective. Excess water can also cause loss of pesticides, resulting in environmental pollution. Thus,water sprayer in the preparation of pesticides, their use according to the concentration range, strict control of the amount of water.
Four bogey free to increase the amount of pesticide production and sales of pesticides before being allowed to go through rigorous field trials, and then determine dosage, administration time, frequency of administration, the actual use of the data. Therefore, in accordance with instructions on the required amount of pesticide that can achieve the control effect, and increase the dosage not only increased investment, but also to make crops produce injury, increase the amount of pesticide residues in agricultural products, increasing environmental pollution.
Five Note unreasonable application of pesticides can increase some pesticide mixing control effect, reduce the dosage, or reach Cordyceps rid of pests or effect, and mixed use more labor. However, some pesticides can not be mixed use, such as organophosphorus pesticides in most varieties of pesticides encountered alkaline or alkaline medium will quickly decompose and failure. Mix pesticides in need, we must understand the nature of various pesticides, characteristics, to ascertain whether it can be mixed, the best guide for technicians and then mix.

Pesticide use process issues that need attention
Pesticide mixture
Tobacco production, some farmers in order to save time and reduce labor intensity, mixed together using several pesticide spraying method. The right mix might improve efficiency and efficacy of pesticides, but confusing mix of pesticides. To rid of pests and mixing several different spraying must take into account the occurrence of each pest and pesticide suitable period of time as well as the persistence of each drug, and only in the event period, spraying suitable period and persistence can be a good match and ensure good medical case mix is reasonably practicable. Otherwise, it will lead to at least a potion mixed useless, in fact, unnecessary wastage, increasing farmers unnecessary financial burden and environmental pressures. Generally, Bordeaux mixture and other alkaline pesticides and biological pesticides bt emulsions should be used alone; conventional organic phosphorus, pyrethroid insecticides, and fungicides can mix conventional; acaricide can include alkaline pesticides, including almost All pesticides.
The use of pesticides and fogging effect dose
The main producing areas of tobacco leaf samples pesticide residue analysis results show that the amount of pesticide residues in tobacco generally higher. Mainly because farmers pressure sprayers spraying unreasonable, arbitrary increases pesticide concentration, increasing the dose, do not use the meter, often with a random amount of caps, resulting in higher levels of pesticide residues in tobacco and environmental pollution and pesticide waste, and Shi easily lead to injury dose increases, the use of highly toxic pesticides greatly increases the risk of poisoning.
Currently spraying machine quality is generally not high, especially sprayer exist "leaking" a serious problem. For decades farmers have been using the traditional manual compression sprayers, garden water sprayer spray large droplets, the loss of a large amount of liquid. And the existence of errors in understanding that only sprayed on tobacco plants dripping liquid in order to obtain the best control effect. Not really need to quit spraying plants thoroughly wet the whole plant, as long as the distribution of pharmaceutical active ingredients uniform deposition, will be able to play a good efficacy. Promoting tobacco production of large purchase knapsack sprayer (such as Tarzan -18), using a fine mist blower spraying technologies to improve control effect and reduce pesticide use.
