摘　　要：[目的]筛选防治黄瓜枯萎病的药剂。[方法]对安徽省合肥市三十岗乡黄瓜枯萎病进行防治药剂筛选试验。试验中,每7-10 d调查1次。调查采用5点取样,每点调查4株,共20株,记载每小区内发病株数及严重度。[结果]结果表明：1.5%菌线威可湿性粉剂防治效果最好,防效为81.6%;其次为36%粉霉灵悬浮剂,防效76.8%;美洲星液肥亦可有效地减轻黄瓜枯萎病发病程度。对小区产量进行测定发现,1.5%菌线威可湿性粉剂增产率最高,平均增产72.2%;其次为36%粉霉灵悬浮剂增产57.7%;第3位为36%抗萎灵可湿性粉剂,增产率为49.3%;最后为美洲星液肥增产43.7%。[结论]筛选出了防治黄瓜枯萎病的适宜药剂,其中,1.5%菌线威可湿性粉剂最好,36%粉霉灵悬浮剂、36%抗萎灵可湿性粉剂、美洲星液肥依次次之。[Objective] The research aimed to screen the fungicide of controlling cucumber fusarium wilt. [Method] The fungicide screening experiment of controlling cucumber fusarium wilt of Sanshigang county, Hefei city, Anhui province was made. Five sampling points was used to record the number of disease plant and the disease degree, and one time was investigated every 7 - 10 days. [Result] The results showed that the effect of 1.5% Junxianwei WP was the best with control effect of 81.6%. The next was 36% Fenmeiling SC with control effect of 76.8%. Meizhouxing liquid fertilizer also could alleviate effectively the disease degree of cucumber fusarium wilt. The results of yield investigation showed that yield increasing rote of 1.5% Junxianwei WP was the best, and its average increasing rote was 72.2%. The next was 36% Fenmeiling SC, and its average increasing rote was 57.7%. The yield of 36% Kangjunling WP and Meizhouxing liquid fertilizer reduced in turn, and their average increasing rates were 49.3 % and 43.7 % respectively. [ Conclusion] The study screen the suitable fungicide for controlling cucumber fusafium wilt. 1.5% Junxianwei WP was the best, 36% Fenmeiling SC was the second, 36% Kangjunling WP was the third and Meizhouxing liquid fertilizer was the fourth.
