摘要
【目的】田间调查、摸清巴旦杏果树腐烂病发病规律,进行田间不同药剂的药效试验,为科学有效防治巴旦杏果树腐烂病提供依据。【方法】在4月9、10、12日病菌活动及病斑扩展盛期开展不同药剂防治小区试验。【结果】发病规律:早春树液流动时开始传播危害,在4～9月分生孢子器成熟,空气湿度大时,陆续长出分生孢子角,产生大量的分生孢子,进行多次侵染危害,直至越冬前停止侵染。尤以春季为重。植物源杀菌剂、疮流孔绝、长效康复灵防治效果分别为80%、90%、100%,不同药剂对巴旦杏果树腐烂病的防治效果存在差异,但防治效果均在80%以上。【结论】供试的几种药剂对果树巴旦杏腐烂病均有较好的防治效果。
[ Objective] The purpose of this study was to discover the occurrence regularity of almond canker by using different pesticides in the field experiments, thus providing the basis for the scientific and effective prevention of the disease. [ Method ] Occurrence regularity ： the disease begins to spread hazard in early Spring. From April to September pycnidium gets mature with ample moisture stored in the air, conidiophores mature one after another, resulting in a large number of conidia, which cause repetitious harm until Winter. The hazard is especially severe in Spring. We carry out different chemical control experiment when pathogen becomes active and lesion begins to extend on April 9, 10, 12, 2009. [ Result] The control effect of agricultural chemicals such as botanical fungicide, Chuangliukongjue, long -acting kangfuling were 80%, 90% , 100%. Different pesticides used on almond canker produce different effects, but their control effects are all more than 80%. [ Conclusion] The tested pesticides used on almond canker have revealed good control effect.
