摘要
采用灌根的方法,以白菜鲜重、防效为评价指标,进行了化学农药60%百菌清可湿性粉剂(WP)和土黄金可湿性粉剂(WP)与生物农药枯草芽孢杆菌(根肿灭)水乳剂(EW)和解淀粉芽孢杆菌(苗根健)水乳剂(EW)对西藏林芝地区大白菜根肿病防治效果的对比性研究。结果表明:土黄金可湿性粉剂(WP)灌根处理效果最好,平均防效达85.15%,每10株白菜鲜重为7.65 kg;60%百菌清可湿性粉剂(WP)与对照无显著性差异;枯草芽孢杆菌(根肿灭)田间防效为58.20%、解淀粉芽孢杆菌(苗根健)为58.55%。
Used chemical pesticides 60%chlorothalonil WP,Terra-Gold WP,biological pesticides Bacillus subtilis EW and Bacillus amyloliquefaciens EW to control Cabbage Clubroot Disease in Linzhi area.The 4 pesticides applying methods were pharmaceutical irrigating.The results showed that Tuhuangjin WP pharmaceutical irrigating had the most notable control effeet,which could be high up to 85.15%.The average fresh weight for ten individuals Chinese cabbage of Terra-Gold WP was 7.65 kg.significantly higher than other treatments,chemical pesticides 60%chlorothalonil WP,there was no significant difference in control effect.The control effect of biological pesticides Bacillus subtilis and Bacillus amyloliquefaciens EW was 58.20%and 58.55%respectively.
