6 errors out of pesticide use

There are six misunderstandings in the use of pesticides in agricultural production:
Use high-toxicity pesticides for low-volume spraying When high-toxicity pesticides are used for ultra-low-volume spraying, the concentration of the sprayed liquid is higher than that of conventional drugs in order to maintain the efficacy. Low-volume sprays are limited to spraying less toxic pesticides such as horses. Lauryl phosphorus, safrole, dimethoate and pyrethroid pesticides, etc., and require the use of personnel must always stand in the wind of the drug-free walk. 1605. Highly toxic pesticides such as methamidophos are forbidden to be used for ultra-low-level sprays to avoid causing productive poisoning.
The use of granules pesticides soaked in water spray granules pesticides, specifications, composition, etc., are mostly based on the biological characteristics of its control objects and protected objects and the environmental conditions of the drug site development and production, and thus have a strong special, special effects And targeted delivery. Currently used primarily for ground and underground medications. Control weeds or pests, no water spray. In addition, the granules of the original drug are mostly highly toxic pesticides, after the reduction of toxicity after granulation, can increase the safety of use, flooding spray will make its toxicity recovery, easy to use pesticide poisoning.
Wettable powder sprayed with a wettable powdered pesticide is a powder obtained by adding a certain amount of a wetting agent and a filler to the original medicine and powdered by mechanical milling or a divided powder. Compared with a general powder, the active ingredient has a high content and flows. Poor sex. Therefore, it can only be used as a suspension after dissolution, and it cannot be directly sprayed as a powder.
High temperature, strong winds, cloudy and rainy days The suitable temperature for pesticide spraying is 20°C~30°C. If the temperature is too high, the chemicals will be easily decomposed and volatile, which will affect the control effect. It will also easily cause pesticide poisoning. The application of pesticides in windy weather, the pharmacy is easy to drift with the wind, it is difficult to reach the target part, not only can not receive the effect of application, but also seriously pollute the environment. Therefore, it is stipulated that the wind speed during spraying should not exceed 1 m/s. In addition, most pharmaceutical agents are not resistant to rain and rain, and are sprayed in rainy weather. They are easily scattered, making it difficult to achieve the desired results and polluting the environment.
Emulsifying and suspending pesticide well water with well water contains a large amount of calcium and magnesium substances. Dilution with well water will destroy the emulsifying and suspending properties of the pesticide, so that the efficacy will be reduced or even completely lost. This will not only affect the control effect, but also cause phytotoxicity.
Randomly expand the scope of medication mainly refers to agricultural herbicides, such as: grass Gan Ning mainly used in orchards, woodlands and other gardens, nursery herbicides, herbicide because of different drug properties, can not be used for field crops; grams can be used for corn, mulberry Park weeding, but the use of protective cover should be used to prevent accidental spray, causing phytotoxicity.
