摘要/Abstract

摘要： 通过田间调查,梳理牛大力病虫害种类及流行规律。采取随机区组设计,比较不同药剂对牛大力的防治效果,探索最佳的绿色防控技术。结果表明,牛大力病虫害发生较少,但其在幼苗时期容易感染病害及虫害,主要包括了根腐病、锈病、白粉病、炭疽病、霜霉病、叶枯病、根结线虫病及蚜虫等;5种药剂对牛大力白粉病的防治均有效果,其中,25%三唑酮的防治效果为98.0%,42%寡糖·硫磺的为89.0%,1%蛇床子素的为76.8%,0.5%大黄素甲醚的为27.6%,哈茨木霉菌的为13.8%。25%三唑酮、42%寡糖·硫磺、1%蛇床子素3种药剂的防治效果最好,且三者间无显著差异;牛大力白粉病的最佳绿色防治技术为42%寡糖·硫磺与1%蛇床子素交错使用。

Abstract: The pest species and epidemic regularity of Callerya speciosa were studied through field investigation. A randomized block design was used to compare the control effects of different pesticides on powdery mildew of Callerya speciosa and explore the best green control technology. The results showed that there were few diseases and insect pests in Callerya speciosa, but it was easy to infect diseases and insect pests in seedling stage, mainly including root rot, rust, powdery mildew, anthracnose, downy mildew, leaf blight, root knot nematode and aphid. Five fungicides were effective in controlling the powdery mildew of Callerya speciosa. The control effect of 25% triadimefon was 98.0%, 42% oligosaccharides · sulfur was 89.0%, 1% osthole was 76.8%, 0.5% physcion was 27.6%, Trichoderma harzianum was 13.8%. 25% triadimefon, 42% oligosaccharides · sulfur and 1% osthole had the best control effect, and there was no significant difference among them. The best green control technology for powdery mildew of Callerya speciosa is intermingled use of 42% oligosaccharides · sulfur and 1% osthole.
