WebTherefore, cyfluthrin is 42% active isomers when compared to beta-cyfluthrin (41/97 = 42). Therefore, the assumption is that the toxicity endpoints for beta-cyfluthrin should be 42% of the cyfluthrin endpoints (e.g., if the cyfluthrin endpoint is 1 mg a.i./L, than the estimated beta-cyfluthrin endpoint would be 0.42 mg a.i./L). WebThe sorption and desorption of cyfluthrin mixture isomers were determined using batch equilibration method and mobility was studied under laboratory conditions, using packed soil column. The soil types used in the study were clayey, clay loam and sandy clay loam obtained from three tomato farms in Cameron Highlands.
