Field Experiment on the Efficacy of 30%Cinerea·Viagra SC Against Sclerotinia Fuckeliana of Cucumber
The field efficacy,safety and practical promotion value of 30% cinerea·Viagra SC in the control of Sclerotinia fuckeliana of cucumber were analyzed by comparing the field efficacy of different concentrations of the agent,as well as the 25% ridoxazole emulsion and 65% vanmalin wettable powder.The results show that:1)30% cinerea·Viagra SC is effective in the control of Sclerotinia fuckeliana of cucumber.The average prevention effect was 70.16%,and the recommended usage is from 22.2 to 88.8 g.mL/667 m2.And the prevention effect increases with the increase of the dosage;2)The dosage of 30% cinerea·Viagra SC was reasonable,safe to cucumber,and no harm was found;3)In the last investigation,the control efficiency of 25% ridoxazole emulsifiable oil and 65% vanomycin wet-able powder against Sclerotinia fuckeliana of cucumber was 76.40% and 73.41%,and the control efficiency was higher,the yield increase was 17.12% and 15.31%,and the yield increase effect was more obvious,and the variance analysis showed that there is no significant difference between 25% dioxazole emulsion and 65% vanmelin wettable powder and 30% cinerea·Viagra SC,so it can be considered to be combined with 30% cinerea·Viagra SC or alternate use to enhance drug efficacy and reduce drug resistance.
