Reasonable selection of pesticides Some pesticides are greatly affected by temperature, and their efficacy decreases significantly with decreasing temperature. While some pesticides are less affected by temperature, they can exert their normal insecticidal action even at lower temperatures. Therefore, in the cold season to prevent crop diseases and insect pests, we should pay attention to pesticides that are less affected by temperature. In addition, in the prevention of diseases and pests in the dormant period of fruit trees, the use of mineral oil emulsions, pine ester mixture, lime sulfur and other soil pesticides, both economic and effective.

Appropriate increase in the amount of pesticides used in the low-temperature season, under the guidance of professionals to increase the dosage, increase the concentration of the liquid, but not more than "safe high concentration", neither the maximum allowable dosage of phytotoxicity.

When the application temperature is high during sunny high-temperature period, the range and respiratory intensity of pests increase, and the amount of food intake increases. At this time, the application of pesticides will improve the control effect.

Improve the application of pesticides to control greenhouse pests and diseases, as far as possible the use of smog or dust method of spraying, if the spray method of spraying, to reduce the number of control and the amount of liquid spray to prevent excessive humidity inside the greenhouse.

Properly extended safety intervals During the cold season, the degradation rate of pesticides is slow, and the time left in the crops is relatively long, and the number of days from the last application of crops to harvest must be properly extended to ensure the safety of food consumption.

Pharmaceutical Intermediate

Pharmaceutical intermediates refer to high-level intermediate products used for the synthesis of chemical drugs, and are "semi-finished products" in the process of chemical drug synthesis. The pharmaceutical intermediates industry is an important link in the pharmaceutical industry chain. Since pharmaceutical intermediates are mainly used in the production of pharmaceutical raw materials, the pharmaceutical intermediates industry is directly related to the pharmaceutical industry.
