AI Technical Summary

Technical Problem

There is a lack of research on the preparation of suspension agents for the combination of dicetamide and cyanothazole in the prior art, especially in terms of the prevention and treatment effect of late potato disease.

Method used

By screening various additive components, suspension agents containing dicetamide and cyanothazole were prepared. Specific ingredients include dicetamide 10%, cyanothazole 10%, Tersperse 2510 2%, Morwet D-390 2%, Agrlian-755 3%, magnesium aluminum silicate 1%, organic bentonite 0.5%, propylene glycol 4%, sodium chloride 1%, SAG 1522 0.2%, and 100% replenishment for deionized water. The suspension agent improves suspension rate, thermal storage stability and low temperature stability by selecting suitable wetting dispersants, thickening agents and antifreeze agents.

Benefits of technology

It significantly improves the field prevention and treatment effect of the agent, reduces the dosage, and improves the prevention effect of late potato epidemics.
