摘　　要：本文以蒸馏水作对照,比较了5种化学药剂对红颜草莓红中柱根腐病的田间药效。根据5种药剂的推荐使用浓度对红颜草莓苗进行浸根处理,分别在浸根处理后9、12、15、18 d,调查统计不同处理的病情指数、防治效果。结果表明,在草莓感病期间,72%农用链霉素1 000倍液的防效为65.97%,99%噁霉灵4 000倍液的防效为59.07%,二者无显著差异,防效较好,防效高于其他3种药剂。In this paper,the field efficacy test of five chemical agents against Hongyan strawberry red stele root rot was compared with distilled water.According to the recommended concentration of the five pesticides,Hongyan strawberry seedlings were subjected to root immersion treatment,and the disease index and control effect of different treatments were investigated at 9 days,12 days,15 days and 18 days after the root immersion treatment.The results showed that during the susceptible disease of strawberry,the control effect of 72% agricultural streptomycin 1 000 times solution was 65.97%,and the control effect of 99% carbendazim 4 000 times solution was 59.07%.There was no significant difference between the two treatments,and the control effect was better,which was higher than the other three drugs.
