【摘要】 研究选用了6种常用杀线剂对胡椒根结线虫病进行了田间药效试验。结果表明各供试药剂对胡椒根结线虫病均有防效,其中以10%噻唑磷GR表现最佳,药后30、60d10%噻唑磷GR30kg/hm2对幼虫的防效分别为83.68%和89.15%,10%噻唑磷GR22.5kg/hm2处理次之。试验结果表明,10%噻唑磷GR对胡椒根结线虫病不但防效高,且持效期长,是理想的杀线剂。更多还原

【Abstract】 Field experiments were conducted with 6 selected nematicides for pepper root-knot nematode. Fosthiazate 10% GR shows the greatest control efficacy among the tested nematicides. Fosthiazate 10% GR 30 kg/ha provided 83.68% and 89.15% control efficacy respectively at 30, 60 d after application,and fosthiazate 10% GR 22.5 kg/ha follows it. Fosthiazate 10% GR shows high-efficiency and persistent against pepper root-knot nematode and it is worth to be recommended.更多还原
