When autumn is over, the weather is getting colder and the temperature is lower. So for farmers friends, what issues need to be considered when using pesticides in the low temperature season? Today, China's pesticide network Xiaobian will share the experience of many years to share with you as follows:
The low temperature weather pests and diseases are mostly in static dynamics, and the following points should be paid attention to when using pesticides in low temperature seasons:
First, rational selection of pesticides 2. Select pesticides for high temperature and high temperature. Higher temperatures are due to the effectiveness of pesticides.
Third, extend the safe interval of crops The degradation rate of pesticides is slow, and the residual time in crops is relatively long. It is necessary to extend the number of days (ie, the safety interval) of the last application of crops to ensure the safety of food.
4. Appropriate multi-application of soil pesticides In the fruit trees entering the hibernation period, soil pesticides with strong resistance to pesticides can be applied. For example, pesticides such as Bordeaux mixture and stone sulfur mixture are used to control pests, which is economical and effective.
5. Appropriate increase in the amount of pesticides The lower the temperature, the lower the lethality of pesticides. Therefore, the amount of pesticides can be appropriately increased at this time.
Finally, the Chinese pesticide net Xiaobian warm reminder: pesticide pesticides are fully dissolved and diluted, add adhesives when mixing with pharmaceutical liquids, and fully stir to dissolve pesticides. Note that vegetable oil can not be added with vegetable oil or the like as an adhesive.
