摘要
为了筛选防治山药短体线虫病的高效、低毒杀线虫剂,在山药品种棒药上,以不施药为对照(CK),选用10.5%阿维·噻唑膦颗粒剂(播种沟撒施)、42%威百亩水剂(随水浇灌)和99.5%氯化苦液剂(土壤注射)3种杀线虫剂进行了田间药效试验。结果表明:3种杀线虫剂均对山药短体线虫有一定的防治效果,且可以明显提高商品山药率和商品山药产量,其中,42%威百亩水剂和99.5%氯化苦液剂处理效果较好,对山药短体线虫病的防治效果分别为95.10%和93.35%,增产率分别为546.10%和472.37%。42%威百亩水剂施用效果最好,且施药方法简单、方便,更具推广应用的潜力。
In order to screen the medicine for controlling Pratylenchus coffeae disease of Chinese yam,the field efficacy test was carried out by three pesticides of 10.5%avifosthiazate granules,42%granville acres of water and 99.5%chloropicrin solution.Avifosthiazate granules used sowing ditch applicator,granville a cresusing water with irrigation method and chloropicrin solution using mechanical soil injection method respectively.The results showed that the efficacy of the three agents was 45.33%,95.10%and 93.35%respectively.The percentage increase in production was 546.10%and 472.37%by granville acres of water and chloropicrin solution.42%granville acres of water have the potential to promote the application because it has not only the best prevention and treatment results,but also simple and convenient application.The test results provide theoretical basis for the control of Pratylenchus coffeae disease in Chinese yam field.
