One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 4971-56-6, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4971-56-6, Name is Furan-2,4(3H,5H)-dione, molecular formula is C4H4O3
Laboratory bioassays were conducted to determine the toxicity of spiromesifen, a tetronic acid insecticide to eggs, nymphs, and adults of the sweetpotato whitefly, Bemisia tabaci (Gennadius) biotype “B”, on melon and collard. Two field trails we also conducted to determine the efficacies of spiromesifen at four different rates (96, 112, 114, and/or 149g [AI]/ha) against B. tabaci on melon and collards. Foliar sprays of thiamethoxam and/or buprofezin were used for comparisons. In laboratory bioassays, spiromesifen was highly toxic to nymphs of B. tabaci on both melon and collard, causing ?100% mortality to young nymphs (first and second instars). Spiromesifen was moderately toxic to old nymphs (third and fourth instars), but not toxic to eggs (2.8-6.3% on melon and 2.9-6.4% on collard and slightly toxic to adults 4.5-15.1% on melon and 25.1-37.0% on collard). Spiromesifen was also highly toxic to the early first instars or crawlers that hatched from the survived spiromesifen-treated eggs, and they died shortly after they became sessile on treated leaf surfaces. Field efficacy trials indicate that spiromesifen showed excellent promise as a foliar spray. One application of spiromesifen at a rate of 149g [AI]/ha or two applications at 122 and 149g [AI]/ha were as effective as two applications of thiamethoxam and buprofezin on melons. On collards, three rates of spiromesifen (96, 114 and 149g [AI]/ha) provided similar control to buprofezin. Because of its unique mode of action and chemistry, spiromesifen might have potential in integrated whitefly management programs and insecticide resistance management on vegetables and other field crops.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Product Details of 4971-56-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4971-56-6, in my other articles.
