41.7%氟吡菌酰胺悬浮液不同施药方式对番茄根结线虫的防治效果

Control Effect of Different Application Methods of 41.7% Fluopyram Suspension on Tomato Root Knot Nematode

为比较41.7%氟吡菌酰胺悬浮液灌根法、药土穴施法和滴灌法3种施药方式对田间番茄根结线虫的防治效果,以10%噻唑膦颗粒剂处理为药剂对照,以清水为空白对照,在田间开展了41.7%氟吡菌酰胺悬浮液不同施药方式的效果评价试验。结果显示:灌根和药土穴施2种施药方法对番茄根结线虫有较好的防效,分别达到70.4%和66.2%,与10%噻唑膦颗粒剂处理均无显著差异;滴灌方式处理对番茄根结线虫防效仅达到41.8%,显著低于灌根和药土穴施2种处理方式,防治效果较差;因此,建议在田间使用41.7%氟吡菌酰胺悬浮液防治番茄根结线虫时,推荐采用灌根和药土穴施2种施药方式,不建议采用滴灌施药。

In order to compare the field control effects of three application methods of 41.7%fluopyram suspension(root irrigation,hole application of medicated soil and drip irrigation)on tomato root knot nematode,a field evaluation experiment was conducted by taking 10%thiazophos granules as medicament control and clear water as blank control.The results showed that the control effects of root irrigation and hole application of medicated soil on tomato root knot nematode were 70.4%and 66.2%,respectively,and they had no significant difference with 10%thiazophos granules.The control effect of drip irrigation on tomato root knot nematode was only 41.8%,which was significantly lower than that of root irrigation and hole application of medicated soil,and the control effect was poor.Therefore,it was recommended to use root irrigation and hole application of medicated soil at the time of using 41.7%fluopyram suspension to control tomato root knot nematode,but not drip irrigation.
