几种杀线剂对番木瓜根结线虫病的防效

Controlling papaya root knot nematode with several nematicides

研究选用了7种药剂对番木瓜根结线虫进行大田防效试验,结果表明:所有参试药剂的各参试浓度对番木瓜根结线虫的防效均极显著高于空白对照,其中10%噻唑磷GR、5%丁硫克百威GR、1.5%二硫氰基甲烷WP对番木瓜根结线虫的防治效果显著高于其它药剂,且持效性较好。

Field experiments were conducted with 7 selected nematicides for control of papaya root knot nematode. All nematicides at all concentrations showed highly significant efficacy against papaya root knot nematode. Among the tested nematicides, fosthiazate 10% EC, carbosulfan 5% GR, and dithiocyanomethane 1.5% WP provided the greatest control and showed good residual control.
