The use of pesticides in low temperature seasons requires attention to four aspects

Today's pesticide market, the variety of species, so that farmers can not distinguish between true and false, and the wrong, unreasonable use of pesticides often lead to a number of pesticide poisoning, pesticide residues exceeding the standard, crop phytotoxicity and other phenomena. Therefore, the rational use of pesticides is very necessary. The weather conditions of pesticides are also an important factor affecting the efficacy of pesticides. What should be paid attention to when using pesticides at low temperature? The following small series will introduce the precautions for using pesticides at low temperature.

What problems should be paid attention to when using pesticides at low temperature?

1. Select a time zone with good weather or high temperature

When the application temperature is high during high temperature and high temperature, the activity range and respiratory intensity of the pest increase, and the feeding amount increases. At this time, the application is beneficial to improve the control effect.

2, appropriate increase in dose

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

3. Continuously improve the application method

Improve the application method in the winter and spring season 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 prevent the humidity inside the shed.

4. Extend the safety interval of pesticides

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.

Here, Xiao Bian warmly reminds everyone that pesticides play an important role in agricultural production. However, the use of pesticides is not scientific and reasonable, and many pesticide poisonings often occur. Therefore, rational application of drugs is very important. I hope everyone can remember.

LSAW pipe machine

LSAW pipe mill, also known as JCOE steel pipe, it has one welding seam and uses the submerged arc welding process. The specification range is from 325mm to 1420mm. When the diameter of the straight seam submerged arc welding pipe is greater than 914.4 mm, the standard stipulates that steel pipes is allowed to have two straight welding seams.
