Farmers can not do without planting, farming inseparable from pesticides. A variety of pesticides, herbicides, fungicides, foliar fertilizer, in the end how to fight drugs, in order to improve the use of pesticides effect? Why the same pesticides, and some people used the effect is very good, some people use no effect?

Wang Xiuyun teacher planted 20 years of vegetable sheds, but also throughout the country for eight years of agricultural technicians. Many peasants said that the same medicine, Wang is the effect of distribution is good, is it what Wang dispensed trick? Xiao Bian made a special trip to find Wang Xiuyun teacher asked what pesticides to use "Cheats," Wang laughed, what cheats, the role of pesticides are similar, the key is to see the following points, remember, with the pesticide effect with less !

The first is the right medicine, according to the prevention and treatment of pesticides to choose the corresponding product. Such as pesticides, it is sucking insect pests or chewing? Fungicide It is fungal or bacterial control, is protective or therapeutic? According to the characteristics of the control object, select the corresponding pesticide products.

Second, medication temperature options. When playing the temperature of the appropriate number of drugs? The best wheat herbicides above 10 degrees, the best corn herbicides within 30 degrees, different pesticides need different temperatures, to understand and comply.

Third, medication time. Is the morning of the evening medication, or noon medication, which is also argument. Such as planthoppers, aphids these migratory pests, according to its schedule. It had poor flight ability in the early evening. Morning medication. Corn herbicides in the morning and evening medication, you can use dew to disperse the agent, the effect is better.

Fourth, the way of medication. The same composition of pesticides, the use of different ways, the effect of a lot of gaps. Spraying, spreading, points Shi effect is not the same. For example, a few years ago a difficult way corn two members of the night worm, in fact, the main method is not medication, chlorpyrifos, phoxim, wheat bran sprinkle applied to the roots of corn, the effect is very good. The spraying effect is poor, because the pests are from the soil at night out of crops, the general effect of the fight is not good.

Fifth, the rational use of pesticide additives. Such as silicone penetrants and extenders, most of the pesticide can be used to join the organic silicon-based penetrants and extenders to increase efficacy, pay attention to herbicides can not be added, pyraclostrobin can not add, cream formulations can not plus. There are insecticides add lure agents, such as sugar, you can lure aphids, planthoppers and other aggregation, improve insecticidal effect.

Sixth, choose the right seven pharmaceutical methods and order. Any pesticide should be used after the second dilution. That is, first with 1000 grams of water to pesticides formulated as liquid medicine, added to the container in a second dilution to a suitable multiple use. Pharmaceutical order basically follow the guidelines for the first bactericidal worm, foliar - powder - SC - insecticide - acaricide, or foliar fertilizer, WP, SC, water, EC Followed by adding, each adding a full mixing, then add the next one.

Seven is the way of dispensing and order. Any pesticide should be used after the second dilution. That is, first with 1000 grams of water to pesticides formulated as liquid medicine, added to the container in a second dilution to a suitable multiple use. Pharmaceutical order basically follow the guidelines for the first bactericidal worm, foliar - powder - SC - insecticide - acaricide, or foliar fertilizer, WP, SC, water, EC Followed by adding, each adding a full mixing, then add the next one.

Listened to the senior agronomist Wang Xiuyun pesticide pharmaceutical "Cheats", farmers friends learn how to improve pesticide efficacy? Formulation. In general, emulsifiable pesticide penetration, suspension more stable, microcapsule suspension pesticide longer duration. According to the use of the object to choose the appropriate pesticide formulations.
