Control Efficiency of Clethodim(Selectone) 240g/L EC to the gramineous Weeds in Sunflower Field
摘要
Abstract
For the purpose of enhancing the selectivity of herbicides in controlling gramineous weeds in sunflower fields, delay the development of resistance in weeds and prolong the action time of herbicides, field trial was conducted to investigate the control efficiencies of clethodim(Selectone) 240g/L EC 45-100ml/667m 2 and with anequivalent dose of Amigo adjuvantin 2012. Results showed that the tested single herbicide has good field performance in terms of readily availability, persistence and control efficiency in controlling annual gramineous weeds,the control efficiencies in 15d and 35d after treated are both above 94.3%, similar to the controlagents Haloxyfop-p-methyl 10.8%EC and Quizalofop-p-ethyl 10%EC.In case of perennial reed, the fresh weight control efficiencies of clethodim 35d after treatedare from 56.9%to 76.5%, not as good as the control agents Haloxyfop-p-methyl 10.8%EC and Quizalofop-p-ethyl 10%EC,88.9%and 91.6%respectively. However, after the addition of adjuvant, the fresh weight control efficiencies of clethodim at different dosage levels are significantly increased, which are from 56.9%to 76.5%35d after treated. Especially at the dosage of 80ml/667m2 and 100ml/667m2 and, both control efficiencies were above 93.1%,better than the control agents and safely to sunflower.关键词
