【摘要】 通过田间试验调查,研究了7种化学药剂对马铃薯植株和薯块晚疫病的防治效果。结果表明:7种药剂对马铃薯晚疫病均可达到显著防治效果。防治效果最好的4种药剂为25%瑞凡、50%福帅得、0.5%苦参碱和30%甲霜.嘧菌酯,防治效果均达到80%以上;其次为45%三苯乙酸锡和68.75%银法利,防治效果达到70%以上;较差为52.5%抑快净,防治效果达到65%。建议在生产上交替使用,避免产生抗药性。更多还原

【Abstract】 Control efficacy of seven fungicides onA potato late blight was determined in field experiment.The Seven fungicides had obvious control efficacies on potato late blight.The best four fungicides were 25% Mandipropamid,50% Fluazinam,0.5% Matrine and 30% Azoxystrobin,and control efficacies of these fungicides were more than 80%.Followed fungicide is 45% triphenyltinacetate,68.75% Fluopicolide,and control efficacy was more than 70%.The worse fungicide was 52.5% Famoxadone + Cymoxanilm,and control efficacy was 65%.These fungicides should be recommended for use alternatively in potato production to avoid resistance.The results provided scientific references to the exploration of new method on potato late blight prevention and yield saving.更多还原
