Research and Development of 20% Nicosulfuron·Atrazine Oil Miscible Flowable Concentrate

It was results show that nicosulfuron and Atrazine with the different ratio have the synergized action to plants of the monocotyledon and double seed leaf weed by the indoor bioassay of crabgrass (Digitaria ciliaris) and purslane. When Atrazine: nicosulfuron = 17:3 ratio of compatibility, the co-toxicity coefficient is the largest and showing an enhancement effect of the most significant. The 20% nicosulfuron and Atrazine of Oil Miscible Flowable Concentrate was processed by ultrafine grinding in the wetting emulsifier, dispersant, thickener, solvent, were screened test to decide the best formula. This preparation showed after (0±1)°C low temperature and (54±2)°C thermostble experiment's result the outward appearance not obvious lamination, in the water the dispersivity is good, each target conforms to the Oil-based Suspension related standard.
