摘要:
为高效、低残留地防治马铃薯晚疫病，进行了9种药剂组配防治马铃薯晚疫病的药效试验。结果表明：处理B[80%乙蒜素EC+80%代森锰锌WP+（80%乙蒜素EC+80%代森锰锌WP混配）]对马铃薯晚疫病的防治效果最好，其次是C[80%乙蒜素EC+80%代森锰锌WP+（80%乙蒜素EC+50%多菌灵WP混配）]和K[58%甲霜灵·锰锌WP+58%甲霜灵?锰锌WP+58%甲霜灵?锰锌WP]，防治效果分别为81.54%、74.66%、71.27%。折合单产最高的是处理B，为31 303.95 kg·hm-2，其次是处理C和K，为24 363.60 kg·hm-2、23 525.25 kg·hm-2。1%水平上，处理B表现极显著。马铃薯晚疫病常发区要防治3次以上，前期使用保护剂，后期用治疗剂，效果较为理想。
Abstract:
In order to prevent potato late blight with high efficiency and low residue,field experiments for nine kinds of fungicide combinations against potato late blight were conducted.The results showed that the control effect of the treatment B[80% Ethylicin EC+80% Mancozeb WP+ (80% Ethylicin EC+80% Mancozeb WP mixture)] against potato late blight was the best,followed by the treatment C[80% Ethylicin EC+80% Mancozeb WP+ (80% Ethylicin EC+50% Carbendazim WP mixture)] and the treatment K[58% Maganese Zinc WP +58% Maganese Zinc WP+58% Maganese Zinc WP].The control effects were 81.54%，74.66% and 71.27% respectively.The yield of B was the highest,31 303.95 kg·hm-2,followed by C and K,24 363.60 kg·hm-2,23 525.25 kg·hm-2.At 1% level,there was significant difference between B and CK.Potato late blight should be prevented more than thrice where the disease often occurred.In the early part of the disease,protective agent was used,and in the late part of the disease,therapeutic agent was used,the effect of which was more ideal.
