辣椒疫病药剂防治效果及对产量和农艺性状的影响
|
摘要
为筛选出防治辣椒疫病的高效低毒新药剂,以遵辣6号为供试品种,选择68.75%银法利、58%甲霜灵猛锌、69%烯酰吗啉·锰锌、72%霜霉疫净及70%安泰生5种药剂进行防效试验,并对施药后辣椒的农艺性状和产量进行调查。结果表明,68.75%银法利、58%甲霜灵锰锌、69%烯酰吗啉·锰锌、72%霜霉疫净及70%安泰生对辣椒疫病的防治效果分别为80.12%、73.2%、59.84%、40.05%和19.88%,用药后辣椒产量分别比对照增产18.39%、15.33%、13.8%、8.05%和6.51%。这5种药剂的综合表现依次为68.75%银法利>58%甲霜灵锰锌>69%烯酰吗啉·锰锌>72%霜霉疫净>70%安泰生。
In order to select new fungicides from 5 fungicides such as 68.75% Farley infinito,58% Metalaxylmancozeb, 69% Dimethomorph-mancozeb, 72% Propamcarb and 70% Antracol for hot pepper phytophthora blight control, Zunla 6 was used as a tested hot pepper variety to investigate its agronomic traits and yield after application of the above fungicides in this study. The results show that the control efficacy of the 68.75% infinito,58% Metalaxyl-mancozeb, 69% Dimethomorph-mancozeb, 72% propamcarb and 70% Antracol on the blight was80.12%, 73.2%, 59.84%, 40.05% and 19.88%, respectively; and the application of the above fungicides increased the fruit yield by 18.39%, 15.33%, 13.8%, 8.05% and 6.51%, compared with the CK, respectively.And the fungicides comprehensively performed as the 68.75% infinito's efficacy > 58% Metalaxyl-mancozeb's >69% Dimethomorph-mancozeb's > 72% propamcarb's > 70% Antracol's in the test.
