摘要
评价不同杀菌剂添加助剂3%卵磷脂·维生素E后减量用药对黄瓜霜霉病和番茄晚疫病的防治效果。采用茎叶喷雾法进行田间药效试验。与杀菌剂全量施用相比,助剂3%卵磷脂·维生素E 5000倍稀释液与全量或减量20%的杀菌剂687.5 g/L氟吡菌胺·霜霉威盐酸盐SC、10%氟噻唑吡乙酮OD+80%代森锰锌WP桶混,可提高杀菌剂对黄瓜霜霉病的防治效果0.8%~5.23%,提高黄瓜产量0~5.5%;提高杀菌剂对番茄叶部和果实晚疫病的防治效果0.94%~5.3%和0.9%~6.0%,提高番茄的产量0.8%~5.8%。防治黄瓜霜霉病和番茄晚疫病效果相当情况下,加入助剂3%卵磷脂·维生素E,可使不同杀菌剂分别减量20%。
To evaluate the control effect of different fungicides added with 3%lecithin·vitamin E on cucumber downy mildew and tomato late blight,field trials was conducted by spray method.Compared with the whole amount of fungicides,the auxiliary 3%lecithin·vitamin E 5000 times diluent mixed with the whole amount or 20%reduced fungicides fluoropyramide·fluoropyramide hydrochloride 687.5 g/L SC,fluoropyridoacetone 10%OD+mancozeb 80%WP could improve the control effect of fungicide on cucumber downy mildew by 0.8%-5.23%,cucumber yield by 0-5.5%,tomato late blight(leaf)by 0.94%-5.3%,tomato late blight(fruit)by 0.9%-6.0%and tomato yield by 0.8%-5.8%.Under the same control effect of cucumber downy mildew and tomato late blight,adding 3%lecithin·vitamin E can reduce the amount of different fungicides by 20%.
