Influence of Application Time of Fungicide on the Control Effect of Mulberry Sclerotium Disease in the Southwest of Zhejiang Province
摘要
Abstract
[Objective]Explore the optimal prevention and control time for mulberry sclerotiniosis in the southwest of Zhe-jiang Province.[Methods]Using the'Yueshen Dashi'('Yuesulda Ten')fruit mulberry cultivar as test material,this study investigated the effects of different initial application times and different application intervals of pesticides on the control efficacy against mulberry fruit sclerotiniosis and the diseased fruit rate in 11-year-old mulberry trees in a plastic greenhouse fruit mul-berry base in southwestern Zhejiang.[Results]The results showed that the first application at the beginning of flowering(March 10),with an interval of 7 days and continuous spraying for 3 times,had the best effect,the prevention efficiency was up to 85.22%,and the rate of disease fruit was about 3.12%.The first application at the beginning of flowering(March 10),with an interval of 10 days and continuous spraying for 3 times,had the second effect,the prevention efficiency was up to 65.35%,and the disease rate was about 7.31%.The worst case was the first application at the early stage of germination(February 10),with an interval of 15 days and continuous spraying for 4 times,the prevention efficiency was less than 50%,and the disease rate was up to 11%.[Conclusion]The method of spraying three times continuously from March 10 at the early flowering stage of mulberry trees with an interval of 7 days is worthy of popularization and application in the prevention and control of mulberry sclerotiosis in southwest Zhejiang.关键词
