【摘要】 为减少蔬菜根结线虫病防治药剂的使用量,提高防治效果,选取不同施用量的41.7%氟吡菌酰胺悬浮剂防治秋茬设施黄瓜根结线虫病,与10%噻唑膦颗粒剂进行防效对比。结果表明:2种药剂均可以抑制土壤线虫量的增加,同期内土壤线虫量的增加较空白对照小,且对黄瓜生长的安全性没有影响。通过对比防治效果和效益,推荐667 m~2使用41.7%氟吡菌酰胺悬浮剂143 mL,667 m~2可增加效益4 163元。更多还原

【Abstract】 In order to reduce the amount of insecticides used for control of vegetable root-knot nematode disease and improve the control effect,41.7% flurpyram suspension concentrate was selected to control root-knot nematode disease of cucumber in autumn stub facilities,and the control effect was compared with 10% fosthiazate granule.The results showed that both of the two insecticides could inhibit the increase of soil nematode content,and the increase of soil nematode content in the same period was less than that in the blank control,and safe for cucumber growth.By comparing the control effect and benefit,it was recommended to use 41.7% flurpyram suspension concentrate 143 mL per 667 m~2,and the benefit could be increased by 4 163 yuan per 667 m~2.更多还原
