First, the rational use of pesticides. 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.
Second, appropriate increase in the amount of medication. In the low temperature season, pesticides should be properly increased under the guidance of professionals to increase the concentration of the liquid, but not to exceed the "safe high concentration" (ie, the maximum allowable dose of no phytotoxicity).
Third, choose a sunny day to apply at high temperatures. When the temperature is high, the activity range and respiratory intensity of the pest increase, and the feeding amount increases. At this time, the application of the medicine is beneficial to improve the control effect.
Fourth, improve the application method. In the winter and spring season, the pests and diseases of greenhouse crops should be controlled by the smoke method or the dust method. If the spray method is applied, the number of prevention and the amount of liquid spray should be appropriately reduced to prevent the humidity in the shed.
5. 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.
Engineered wood flooring trends include the following:
1. Environmental protection materials: With the improvement of people's awareness of environmental protection, more and more consumers choose to use environmental protection materials.
