| 摘 要： | 对9种不同作用机理的杀线虫制剂进行了田间防效评价试验。结果表明，10%噻唑磷颗粒剂、35%威百亩水剂和98%棉隆微粒剂对根结线虫具有良好的防效，不仅能控制土壤中2龄幼虫数量，而且能非常有效地抑制根结的形成，同时具有速效性好、持效期长、残留毒性低等优点，可作为根结线虫防治的首选药剂；5%丁硫克百威颗粒剂和0.5%阿维菌素颗粒剂具有较好的防效，对土壤中2龄幼虫数量和作物根结的形成具有中等水平的控制能力，速效性好、同时具有一定的持效性；生防制剂5亿活孢子/g淡紫拟青霉颗粒剂和2.5亿孢子/g厚孢轮枝菌微粒剂在香蕉生长前期防效较差，而在生长中期的防效逐渐上升并保持稳定；2.5%二硫氰基甲烷可湿性粉剂的表现一般，但可在生长季节多次灌根使用，同时具有毒性低、使用方便的优点，是当前为数不多的、能在作物生长季节里施用的广谱型杀线虫制剂；50%氰氨化钙颗粒剂的表现最差，仅能一定程度地控制根结线虫数量，未能有效地抑制病害的发展，对2龄幼虫的控制能力不超过60 d，生长中后期的2龄幼虫数量和根结指数增长较快。

| Abstract: | Field trials were conducted to validate the efficacy of 9 nematicides in controlling root knot nematodes. The results indicated that fosthiazate 10% GR, metham sodium 35% AS and dazomet 98% MG showed the best effects on nematode larvae and formation of root knots, followed by carbosulfan 5% GR and abamectin 0.5% GR, which had good effects on J2 and production of tumours. 5×108 living conidia /g Paecilomyces lilacinus GR and 2.55×108 living conidia /g Verticillium chlamydosporium MG had bad effects during growth prophase, but their effects increased gradually during growth midphase. Methylene dithiocyanate 2.5% WP had marginal effects, but could be used during the whole growth season. Calcium cyanamide 50% GR showed the worst effect and could not control J2 over 60 d after treatment. |
