Strengthening the key points for farmers to use pesticides at low temperatures

Today, with the type of pesticide continues to increase, more and more users one-sided awareness and safe use of pesticides, enhance the user is very important for the proper use of pesticides. Pesticides play an important role in agricultural production. However, the unreasonable and rational use of pesticides often leads to a series of phenomena such as pesticide poisoning, excessive pesticide residues, and crop phytotoxicity. The rational use of pesticides is very necessary. The weather conditions of pesticides are also an important factor affecting the efficacy of pesticides. The following four aspects should be noted when using pesticides at low temperatures:
1. Select the time when the weather is fine or the temperature is high. When the application temperature is high during the high temperature period, the activity range and respiratory intensity of the pest increase, and the feeding amount increases. At this time, the application is beneficial to improve the control effect.
2, appropriate increase in the amount of drugs appropriate to increase the amount of drugs in the low-temperature season application of pesticides, under the guidance of professional agricultural materials users to increase the amount of drugs, increase the concentration of liquid, but not exceed the "safe high concentration" (ie, the highest level of no phytotoxicity Allowed dose).
3, continuous improvement of the application of methods to improve the application of pesticides in winter and spring to prevent greenhouse crop pests and diseases, try to use the smoke method or dust method; if spray application, reduce the number of prevention and discharge, the amount of spray, prevent sheds humidity.
4. Prolong the safety interval of pesticides and prolong the safe interval. In the low temperature season, the degradation rate of pesticides is slow, and the residual time in crops is relatively long. It is necessary to appropriately extend the number of days (ie, the safety interval) of the last application of crops. Make sure you eat safely.
