There are many growers, for convenience, corn post-seedling herbicides can be mixed with pesticides, but the effect is often not good. Can corn post-seedling herbicides be mixed with pesticides?

Can corn post-seedling herbicides be mixed with pesticides?

The two are not suitable for mixed use, the composition of insecticide and post-seedling herbicide is different, and the place is not the same, so it is not suitable for mixed use. Drug damage may occur after mixed use, and it is best to use it separately.

What kind of pesticides can be mixed?

1.1. There is no adverse chemical reaction (such as hydrolysis, alkaline hydrolysis, acidolysis or redox reaction, etc.) between the mixed varieties, which ensures normal efficacy or synergism, and does not affect the physical properties of the agent (such as emulsification, suspension rate reduction, etc.). For example, most organophosphorus pesticides cannot be mixed with Bordeaux solution, stone sulfur mixture, etc., and powders cannot be mixed with wettable powder and soluble powder.

two。 The mixed use of different varieties can not cause drug damage to crops. For example, the mixture of organophosphorus insecticides and paspalum will cause drug damage to rice, and the mixture of Bordeaux solution and stone sulfur mixture can easily cause drug damage to crops.

3. After the pesticide is mixed, it does not increase the toxicity and ensures the safety to people and animals.

4. The mixed use should be reasonable. Including the reasonable collocation of this species, such as the control of Gramineae weeds in soybean field, it can be controlled only by catching and covering grass, and then the mixture of the two can be used, although it is feasible in terms of chemical stability, it is unreasonable, it does not increase efficiency and does not expand the scope of control. Stick is not necessary. The purpose of mixed use of pesticides is to save labor and time and improve economic benefits. for example, after making the mixture, the additional cost is very large and can not be allowed.

5. Pay attention to the antagonistic effect of pesticide varieties to ensure the effect of mixed use, such as bentazone and nachujing reduce the control effect of Gramineae weeds due to antagonistic effect.

Corn post-seedling herbicides and pesticides had better not be mixed to avoid drug damage, it is best to use separately.
