CARAH预警模型在马铃薯晚疫病防治药剂减量增效中的应用
|
摘要
为明确CARAH预警模型对四川马铃薯晚疫病防治药剂减量增效技术的指导效果,针对马铃薯晚疫病感病品种兴佳2号和中薯2号,利用CARAH预警模型监测马铃薯晚疫病的发生和流行。结果表明,中心病株主要在马铃薯晚疫病第3代侵染循环出现,其中秋马铃薯晚疫病发生程度较春马铃薯晚疫病重,且流行速度快。据此,在马铃薯晚疫病第2代第1次侵染循环5分值时减量使用防治药剂,减量处理均表现出较高的防治效果。其中,一个常规用量减量33%的处理(即10%氟噻唑吡乙酮OD 225 mL/hm~2施用2次、间隔14 d)经济效益增幅最高。
To clarify the applicability of CARAH warning model to reduce fungicide dose and increase benefit in control of potato late blight, CARAH warning model was used to determine application timing of fungicide in spring and autumn.Primary infected focus of potato late blight appeared on susceptible variety Favorita and Xinjia NO. 2 when CARAH warning model displayed the 3 rdinfection cycle, where more serious and quickly infection occurred in autumn than in spring. When fungicides were applied at first infection time in the 2 ndcycle with a score of five, reduced dose(by 33%)and excellent control effects were attained. The treatment that reduced by 33% of normal dosage Zorvec 225 mL/hm~2 in autumn showed the highest benefit amplification, which was used 2 times at an interval of 14 days.
