How can pesticide auxiliaries improve the biological activity and utilization of pesticides?

1. Reduce surface tension

Surfactants in pesticide additives can significantly reduce the surface tension of pesticide solutions, making pesticides more easily dispersed and suspended in solutions. This effect of reducing surface tension helps the pesticide to better contact with the target organism and improve the biological activity of the pesticide. At the same time, the pesticide solution with low surface tension can better cover the crop surface, reduce the loss and waste of the liquid medicine, and improve the utilization rate of pesticides.

2. Promote osmosis and absorption

The penetrant in pesticide additives can promote the penetration of pesticide molecules into plants or pests, so that pesticides can reach the site of action faster, and play the role of insecticide and sterilization. This effect of promoting osmosis and absorption can improve the biological activity of pesticides, so that it can obtain better control effect under the same dosage. In addition, penetrants can also enhance the conductivity of pesticides in the plant body, so that the distribution of pesticides in the plant body is more uniform, and further improve the utilization rate of pesticides.

3. Save dispensing water

The suspension agent, dispersant and other components of pesticide additives can make the pesticide form a stable suspension or dispersion system in water, and reduce the precipitation and agglomeration phenomenon of pesticides in water. This stable suspension or dispersion system can save dispensing water and reduce the dilution ratio of pesticides, thereby increasing the concentration and activity of pesticides without increasing the dosage of pesticides. At the same time, a stable suspension or dispersion system can also reduce the loss and waste of pharmaceutical liquid and improve the utilization rate of pesticides.

4. Improve adhesion

The adhesive in the pesticide additive can enhance the adhesion of the pesticide on the crop surface, so that the pesticide is more closely attached to the crop surface, and is not easy to be washed by rain or blown away by the wind. The effect of improving adhesion can extend the holding period of pesticides and improve the utilization rate of pesticides. Under the same control effect, the use of adhesive pesticide additives can reduce the application times and doses of pesticides, and reduce the negative impact on the environment.

5. Avoid waste of liquid medicine

The anti-erosion agent and humectant in pesticide additives can reduce the influence of rain erosion and evaporation on the liquid medicine, so that the liquid medicine can maintain longer adhesion and durability on the crop surface. This effect of avoiding the waste of liquid medicine can reduce the loss and waste of pesticides and improve the utilization rate of pesticides. At the same time, anti-erosion agents and humectants can also make pesticides form protective films in the plant body, further improving the durability and control effect of pesticides.

6. Reduce the amount of pesticides

Through the role of the above several aspects, pesticide additives can significantly improve the biological activity and utilization of pesticides, so as to reduce the amount of pesticides under the same control effect. This not only helps to reduce the cost of agricultural production, but also reduces the pressure of pesticide pollution on the environment and promotes the sustainable development of agricultural production.
