摘　　要：【目的】筛选低毒高效的杀线剂,为半穿刺线虫的防治提供科学依据。【方法】进行10%噻唑膦颗粒剂、2.5亿个孢子/g厚孢轮枝菌微粒剂、0.5%阿维菌素颗粒剂、24.5%阿维菌素乳油、10%丙线磷颗粒剂、2亿/g盐生菌及2亿/g盐生菌+0.5%阿维菌素颗粒剂对柑橘半穿刺线虫田间防治效果试验,药后30d统计不同药剂对柑橘半穿刺线虫的防治效果。【结果】供试的6种药剂对半穿刺线虫均有较好的防效,对土壤中和根上线虫的防效均在50%以上,其中10%噻唑膦颗粒剂的防效最好,对土壤中和根上线虫的防效达80%以上;其次为24.5%阿维菌素乳油和2.5亿个孢子/g厚孢轮枝菌微粒剂,两种药剂对土壤中和根上线虫的防效为70%～75%。【结论】10%噻唑膦颗粒剂、2.5亿个孢子/g厚孢轮枝菌微粒剂和24.5%阿维菌素乳油对柑橘半穿刺线虫有较好的防治效果,且对柑橘生长无不良影响,可作为柑橘半穿刺线虫的防治药剂在柑橘生产上推广应用。[ Objective ]The trial was conducted to screen out high-efficient and low-toxic nematicide to provide scientific references for Tylenchulus semipenetrans control. [Method]Six nematicides vfz., fosthiazate 10%GR, 2.5x10s living conidia/g Vertlcillium chlamydosporium MG, avermectin 0.5%GR, avermectiu 24.5%EC, ethoprophos IO%GR, and 2x l0s salt bacteria/g ＋0.5% avermectin GR were experimented to compare their control efficacy on citrus Tylenchulus semipenetrans in the field after 30 days of spray treatment. [Result]The result showed that the six tested nematicides were highly efficient to Tylenchulus semipenetrans in soil and root with over 50% control efficacy, among which the control efficacy of fosthiazate I O%GR was the highest （80%）, followed by avermectin 24.5%EC and 2.5x I0s living eonidia/g Verticil- lium chlamydospoHum MG （70-75%）. [ Conclusion ]Fosthiazate 10%GR, avermectin 24.5%EC and 2.5x 10s living conidia/g Verticillium chlamydospoHum MG had good control effect on citrus Tylenchulus semipenetrans with no detrimental effect on citrus growth, therefore they can be extendedly applied in citrus production.
