胡萝卜软腐病和黑腐病的病情相关性及协同防治研究
The studies on the correlation analysis of disease development and collaborative prevention of both car-rot soft rot and black rot
摘要
Abstract
[Objective]The project was aimed to explore the correlation of disease development between carrot soft rot and black rot,and to screen out the best control methods for both diseases.[Methods]The studies were conducted in the farm fields with higher disease level during past three years.The efficacy of two pesticides was determined with six different application methods.[Results]By three times application of the fungicides which was targeted to carrot black rot,not only the rate of diseased plants with black rot,but also plants with soft rot were reduced significantly,.Appli-cation of chlorothalonil for two times and followed by once spray of streptomycin produced the control effect of black rot and soft rot at 92.18% and 86.61%,respectively,and the marketable rate was reached up to 96.17%,which was 64.86% higher than the control treatment.[Conclusion]The incidence of carrot black rot was positively co -related to the severity of carrot soft rot.The control of carrot black rot prior to the soft rot can effectively prevent the develop-ment of two diseases,which will reduce pesticide pollution and increase pesticide efficacy.关键词
