通过1987~1989年的研究,肯定以化学防治为主的综合防治,在生产中应用收到显著效果。使用含药介质法和纸碟抑菌法室内筛选,结合田间试验测定速克灵、甲基托布津、多菌灵、退菌特等18种不同有效成份和剂型的杀菌剂,证明有效成份1000ppm的速克灵抑菌效果最好,室内抑菌效果86.11%,田间喷雾预防防效88.89%,治疗防效100%;甲基托布津室内抑菌效果64.44%;田间预防防效75.0%,治疗防效73.68%;多菌灵室内抑菌效果65.56%;田间预防防效77.78%,治疗防效50%。生产中使用50%速克灵wp.1000倍,重病棚在子囊盘出土后3d喷打第1次药,间隔10d喷第2次药,防效93.06%;70%甲基托布津wp.500倍,防效90.61%;50%多菌灵wp.500倍,防效77.55%;50%速克灵wp.和40%超微多菌灵wp.1:1混合剂,比单用多菌灵提高防效。发病初期或轻病大棚,用50%五氯硝基苯wp.50倍的0.2%琼脂胶悬液,涂抹病株的病班有94.23~100%治疗效果。
Through the research from 1987 to 1989, it is affirmed that the comprehensive prevention and control based on chemical prevention and treatment has received significant effects in the application of production. Using drug-containing medium method and paper dish antibacterial method indoor screening, combined with field tests to determine the speed Ke Ling, thiophanate methyl, carbendazim, detoxification 18 kinds of different active ingredients and formulations of fungicides to prove that the active ingredient 1000ppm The antibacterial effect of Klinking is the best, indoor antibacterial effect of 86.11%, field spray prevention and control efficiency of 88.89%, 100% therapeutic effect; methyl thiophanate antibacterial effect of 64.44%; field prevention and control of 75.0% Effective 73.68%; carbendazim indoor antibacterial effect of 65.56%; field prevention and control of anti-effect 77.78%, 50% of treatment control. 50% of the production in the production of grams of speed wp.1000 times, severe disease shed in the first three days after the capsule unearthed blasting the first drug, spraying the second drug interval 10d, control efficiency of 93.06%; 70% thiophanate-methyl wp.500 Times, control effect 90.61%; 50% carbendazim wp.500 times, control effect 77.55%; 50% speed kelp wp. And 40% supermicrobial carbendazim wp.1: 1 mixture, Spirit to improve control efficiency. Early onset or mild disease shed, with 50% pentachloronitrobenzene wp.50 times 0.2% agar gel suspension, smear sick disease class 94.23 to 100% treatment.
