Analysis of the use points of environmentally friendly pesticides and biological pesticides

Biological pesticides are usually safe, effective, and non-polluting, and are harmless to the ecological environment. Because of this, the status and role of integrated pest management is becoming increasingly apparent. Properly mastering the knowledge of biopesticide use can effectively improve the control effect of pests and diseases. The following are the basic points when using it for your reference:
1, the use of medicine to master the temperature of the application temperature should be around 20-30 °C. The active ingredient of the biological pesticide consists of protein crystals and living spores. Once sprayed below the above temperature, the spores propagate slowly in the body of the pest, the protein crystals are difficult to function, and the control effect is poor.
2, medication time In general, the spray is best carried out in the morning and evening, especially the powder pesticides are more effective. Due to the dew in the morning and evening, the agent adheres well to the stems and leaves, and the spores multiply quickly. After the pests eat the stems and leaves, they will die soon. Spraying at high temperature at noon, the ultraviolet light in the strong light will kill the spores and reduce the control effect.
3, grasp the weather changes sunny, cloudy or rain after the best to spray the fine, try to avoid heavy rain, rain will wash away the bacteria, lose the lethality. If it is light rain 5-6 hours after application, it will not reduce the efficacy, but will improve the control effect, because light rain is conducive to spore germination.
4, reasonable mixing can not be mixed with insecticides and fungicides to prevent killing spores. Do not mix with ferromagnetic agents. Please read the instructions carefully when mixing.
5, the application of pesticides should be technically applied on dryland crops, it is necessary to spray the liquid as much as possible, so that each part of the plant is sprayed and sprayed, so as to achieve the purpose of prevention and control.
The China Pesticide Network reminds everyone that in the prevention and treatment of diseases, they should not be blindly mixed. It is necessary to understand the characteristics of pesticides and then rationally mix them to improve the efficacy.
