摘 要: | [目的]探讨川西高原苹果早期落叶病发生规律及药剂防治效果。[方法]于2009~2011年对川西高原苹果早期落叶病进行了系统调查,并对其进行了不同药剂、不同施药时期的防治效果研究。[结果]病原种类以褐斑病为主,占32.5%;灰斑病占29.9%;轮斑病占25.7%。田间消长规律:一般从5月中旬发生为害至10月上中旬结束,但终年只有1个发病为害高峰,且其消长与雨量呈正相关(R2=0.891 8**)。药剂防治试验表明40%福星防效最好(86.5%),且花后施药1次为佳。[结论]为苹果早期落叶病的有效防治提供了理论依据。

Abstract: | [Objective] The research aimed to discuss the occurrence regularity of apple early defoliation disease and its control by fungicide in West Sichuan plateau.[Method] Apple early defoliation disease in West Sichuan plateau was systematically investigated during 2009-2011,and the control effects of different fungicides during different spraying periods were studied.[Result] The species of pathogen mainly was Marssonina mali(P.Henn),accounting for 32.5%,Phyllosticta Pirina Sa accounted for 29.9%,and Alternaria mali Roberts accounted for 25.7%.The field fluctuation rule was as follows: the disease generally began in the mid-may and ended in early and middle October with only one damage peak during the whole year,the fluctuation had positive correlation with rainfall(R2=0.891 8**).Control test showed that 40% flusilazole had the best control effect(86.5%),which was best to apply after anthesis.[Conclusion] The paper provided theoretical basis for the effective control against apple early defoliation disease. |
