Preparation And Application Technology Of Nicosulfuron Oil Miscible Flowable Concentrate In Maize Field

Based on expounding present applying situation of herbicides in maize fields,the research is to study and develop new stem and leaf treatment herbicide-4% nicosulfuron which has high efficiency, low residue and amity to environment and concern with some research on preparation directions as well as technics conditions. The research testifies the activity of nicosulfuron and the safety to crops by potted methods in Greenhouse and trials in field. It has been tested and applied widely in the fields.The results of the thesis are as follows:1.Effect-improved trials in greenhouse using potted methods: esterificated soybean oil as a dispersed medium is selected among 32# diesel oil, soybean oil and esterificated soybean oil. Esterificated soybean oil has obvious effect-improved on Nicosulfuron.2.Surfactant and densification used to process oil suspension concentrate were selected by optimization and combination. Surfactant monomer NPEPO4 and OP-6 were mixed into compound surfactant by a proportion of 4 to 1.The final selected direction...
