A Security Analysis of Different Herbicides against Japonica Rice Weeds and Control Strategies
摘要
Abstract
Based on different herbicidal agents applied to different japonica rice variety and planting mode field, through 5 stages of preemergence after sowing, seedling after sowing, late tillering after transplanting 6 d, and booting stage, field weeding effects were conducted and safety demonstration tests were observed. Results showed that:40%bensulfuron∙metolachlor WP was used in the live japonica rice field during preemergence after sowing, with ideal weed controlling effects and good security; oxazole acid 10% metolachlor EC, 2.5%pentafluoro alachlor oF, 10%fluorine cyanide mexyl EW, 50%quinclorac WP and other agents were used in the live japonica rice field during the rice seedling after sowing, with good weeding security, but the controlling <br> effects of pentafluoro alachlor and quinclorac against barnyard grass were not so good in the drug resistance fields; during the seedling after sowing, live japonica rice got injury from the herbicides, so its submergence tolerance was weaker than that of indica rice, and so was that of japonica than that of partial indica japonica;30% bensulfuron propisochlor WP, 37.5% bensulfuron butachlor WP, 25% WP bensulfuron acetochlor and other agents were used in the japonica rice transplanting fields, with more ideal weed controlling effect and good security; 46% 2 A bentazone SL and 9% ethyl oxime cyhalofop ME were used at the end of tillering japonica administration, with better security; bispyribacsodium and its compound preparation could only be used at the end of tillering to live japonica with 4 leaves, with poor security; different types of japonica rice (partial indica, partial japonica), when used the same kind of herbicide with poor security, their sensitivity was different;the herbicide resistant force of conventional japonica rice or japonica was weaker than that of indica japonica. So, here the paper proposed the integrated weed control strategies.关键词
