Pesticide additives know more about the choice

Usually, the pesticide adjuvant itself has no biological activity, but whether the auxiliary agent is properly selected has a great influence on the efficacy of the pesticide preparation. The details are as follows:
For example, a blended emulsifiable concentrate containing 10% of propanil and 30% diesel has a similar herbicidal effect to 20% of the enemy's emulsifiable concentrate without diesel fuel, while the amount of enemy scorpion is one time difference; if Bordeaux mixture is used, Add 0.2%~0.3% bone glue, which can resist rain washing and improve the disease prevention effect. The rational use of pesticide additives can often improve the safety of the pesticides on plants and reduce the toxicity to humans and animals. Filler: Filler can be used to dilute the original drug, reduce the original dose, make the original drug easy to mechanically pulverize, increase the dispersion of the original drug, is a filler for the manufacture of powder or wettable powder, such as clay, talcum powder; wet exhibitant : It can reduce the surface tension of water, making it easy for water to wet the additives on the solid surface. When the liquid is sprayed onto the surface of the drug, it is easy to spread on the surface of the drug, and the control effect is enhanced, such as tea dryness.
According to the Chinese Pesticide Network , dispersants are divided into two types: one is a pesticide stock dispersion, which is a substance with high viscosity properties. By mechanical action, the molten pesticide can be dispersed into colloidal granules, such as waste sticky honey. The concentrate, the pulp waste concentrate; the other is a dispersant of the pesticide preparation, which can prevent the powder from flocculation, so that the powdered pesticide can be well dispersed when sprayed. Synergist: It has no insecticidal or bactericidal effect, but it can improve the insecticide and bactericidal effect of the original drug.
The above is a brief introduction to the scientific selection of pesticide additives. I think everyone knows it. The pesticide network reminds everyone that it is king to carry out scientific understanding of pesticides before using them.
