摘  要：
[目的]筛选防治马铃薯早疫病的有效药剂,明确供试药剂对早疫病的防治效果。[方法]通过马铃薯早疫病田间防治效果试验,对比早疫病发病情况、药剂的安全性及产量等,综合评价药剂的防治效果。[结果]各药剂对马铃薯植株生长是安全的;第3次施药后7d,40%甲硫·氟啶胺SC、50%咪鲜胺铜盐SC、36%硝苯菌酯EC、22.5%啶氧菌酯SC、50%异菌脲WP、50%啶酰菌胺WG、40%腈菌唑WP以及70%丙森锌WP等对早疫病的防效分别为85.94%、91.73%、84.20%、91.19%、82.91%、89.93%、91.79%和89.49%,分别增产4.49%、20.61%、8.15%、18.50%、5.64%、8.07%、17.95%和8.46%。[结论]依据冀东地区马铃薯种植和杀菌剂使用现状,推荐使用50%咪鲜胺铜盐SC、22.5%啶氧菌酯SC及40%腈菌唑WP防治马铃薯早疫病。

摘  要：
[Aims ] The paper aims to screen out the effective fungicides for control of potato early blight, so as to clarify the control effect of the tested fungicides on the potato early blight in field. [Me thods ] By comparing the incidence of early blight in the field, the safety of fungicides and the yield of plots, the field control effect of the tested fungicides was evaluated comprehensively on potato early blight. [Re s ults ] The tested fungicides were safe to growth of potato. The results showed that the control effect of the tested fungicides(thiophante-methy·fluazinam 40% SC,prochloraz copper 50% SC, meptyldinocap 36% EC, picoxystrobin 22.5% SC, iprodione 50% WP, boscalid 50% WG,myclobutanil 40% WP and propineb 70% WP) on the potato early blight were 85.94, 91.73, 84.20, 91.19, 82.91, 89.93,91.79 and 89.49% respectively. The yied increased by 4.49, 20.61, 8.15, 18.50, 5.64, 8.07, 17.95 and 8.46%respectively. [Conclus ions ] According to the local potato cultivation and fungicides in the eastern of Hebei province,prochloraz copper 50% SC, picoxystrobin 22.5% SC and myclobutanil 40% WP could be recommended to use extensively to control potato early blight in field.
