Winter temperatures are relatively low, and pesticides may be taken care of. If some pesticides are used at low temperatures, the efficacy will decrease with the lower temperature, so it is not suitable for winter use. Therefore, there are still some aspects that need attention in winter. What are the pesticides suitable for winter use?
Pesticide suitable for winter use
Some pesticides (such as dimethoate) are more affected by temperature, and their efficacy is significantly reduced with decreasing temperature, while some pesticides (such as omethoate) are less affected by temperature, even at lower temperatures. (Under 15 °C), it can also exert its normal insecticidal effect. Omethoate and other similar well fenvalerate, insecticide toxic effects at a low temperature (15 ℃) but higher than the temperature at (25 ℃). 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.
There are three aspects to be aware of when using pesticides in winter:
1. Appropriately increase the dosage. In the low temperature season, the pesticide should be properly increased under the guidance of a professional to increase the concentration of the liquid, but not to exceed the "safe high concentration" (ie, the maximum allowable dose without phytotoxicity).
2. Improve the application method. In the winter and spring season, the crop pests and diseases in the greenhouse are controlled. The method of spraying by the smoke method or the dust method should be applied as much as possible. If the spraying method is applied, the number of prevention and the amount of liquid spray should be appropriately reduced to prevent the humidity in the shed from being too large.
3. Properly extend the security interval. In the low temperature season, the degradation rate of pesticides is slow, and the time remaining 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 safe food.
