How to rationally apply pesticides in low temperature season

The temperature in winter and early spring is low. When controlling crop pests and diseases, we must pay attention to the rational application of pesticides.

Reasonable selection of pesticides Some pesticides (such as dimethoate) are greatly affected by temperature, and their efficacy is significantly weakened with the decrease of temperature, while some pesticides (such as omethoate) are less affected by temperature, even in comparison. At low temperatures (below 15 ° C), it also exerts its normal insecticidal action. Similar to omethoate, there is also a pyrethroid, which is more toxic at low temperatures (15 ° C) than at high temperatures (25 ° C). Therefore, in winter and spring low temperature seasons to control crop pests and diseases, we must pay attention to the use of pesticides with less temperature impact.

Properly increase the dosage of pesticides in the low-temperature season. Under the guidance of professionals, increase the dosage and increase the concentration of the liquid, but not exceed the “safe high concentration” (ie, the maximum allowable dose without phytotoxicity).

Improve the application method 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 and the amount of liquid spray to prevent excessive humidity in the shed.

Appropriately extend the safe interval. In the low temperature season, the degradation rate of pesticides is slow, and the residual time in the crops is relatively long. It is necessary to appropriately extend the number of days (ie, the safety interval) of the last application of the crops to ensure food safety.
