采用灌根、拌种、拌种+灌根的方法,研究了化学农药75%百菌清可湿性粉剂(WP)、40%多菌灵·福美双(烂根愈)WP及生物农药枯草芽孢杆菌(根肿灭)水乳剂(EW)对西藏林芝地区普通白菜(小白菜)根肿病的防治效果。结果表明:拌种+灌根复合处理比单一处理效果好,其中,75%百菌清WP拌种+灌根的防治效果最为显著,防效高达95.6%;生物农药枯草芽孢杆菌EW拌种+灌根的防治效果为89.5%,与同样处理的40%多菌灵·福美双WP防效(90.1%)差异不显著。
The effects of chemical pesticide 75% chlorothalonil WP, 40% carbendazim, thiram (Radix Rehmanniae) WP, and the biopesticide Bacillus subtilis Bacillus (Edema) Water Emulsion (EW) for Prevention and Cure Effects on Clubroot Disease of Common Chinese Cabbage (Brassica chinensis) in Linzhi Prefecture of. The results showed that seed dressing + irrigation and root combination treatment had a better effect than single treatment. Among them, 75% chlorothalonil WP seedling and irrigation root were the most effective, the control efficiency was as high as 95.6%; the biological pesticide Bacillus subtilis EW seed dressing + The control effect of irrigation was 89.5%, which was not significantly different from that of 40% carbendazim and thiram (90.1%) treated with the same treatment.
