摘要
以常规药剂70%烯酰·嘧菌酯水分散粒剂为对照,比较了生物农药几丁聚糖防治莴笋霜霉病的效果。试验结果表明,单一施用几丁聚糖防治效果不明显,建议与常规药剂烯酰·嘧菌酯混用,不仅防效增加,且可使莴笋增产。
This research compared the effects of biopesticide chitosan and enoyl -azoxystrobin water dispersible granule on lettuce downy mildew. The results showed that applying chitosan had no obvious control effect. Chitosan should be applied with enoyl-azoxystrobin, not only heightened the control effect, but also increased the lettuce yield.
