摘要
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。
Used chemical pesticides 75% chlorothalonil WP and 40% carbendazim·thiram WP,biological pesticides Bacillus subtilis EW to control pakchoi clubroot in Linzhi area.The 3 pesticides applying methods were pharmaceutical irrigating,seed dressing and seed dressing+irrigating.The results indicated that 75% chlorothalonil WP seed dressing+irrigating had the most notable control effect,which could be high up to 95.6%.The control effect of biological pesticide Bacillus subtilis EW seed dressing + irrigating were 89.5%,there was no significant difference in control effect with 40% carbendazim·thiram WP seed dressing + irrigating(90.1%).
