摘要: 【目的】 明确41.7%路富达SC不同施药方式对设施番茄根结线虫的防治效果。【方法】 设41.7%路富达SC 用药量0.030 mL/株,分别进行灌根、垄面喷雾、畦面撒施,对照药剂为20%噻唑膦FW灌根、10%噻唑膦GR 30 kg/hm2地面撒施及清水处理,调查不同处理对根结线虫防治效果。【结果】 41.7%路富达SC灌根、垄面喷雾、畦面撒施3个处理的虫口减退率校正防效分别为46.39%、23.21%、22.95%,防效分别达64.19%、59.74%、50.22%;对照药剂20%噻唑膦FW、10%噻唑膦GR的虫口减退率校正防效分别为42.67%、29.89%,防效分别为62.21%、48.46%。与清水处理相比,41.7%路富达SC灌根增产幅度达27.07%。【结论】 41.7%路富达SC灌根处理对设施番茄根结线虫的防治效果显著优于垄面喷雾、畦面撒施和对照药剂处理,增产效果显著。

Abstract: 【Objective】To determine the control effect of 41.7% Lufuda SC different application methods on root-knot nematode of tomatoes.【Methods】41.7% Lufuda SC at a dosage of 0.030 mL/plant was used to irrigate the root,spray on ridge surface,and broadcast on strip surface. 20% fosthiazate FW for root irrigation,10% fosthiazate GR at 30 kg/hm2 soil spraying and water were used as controls. The effect of different treatments on root-knot nematode control was recorded.【Results】The population declining rates of root-knot nematode by 41.7% Lufuda SC treatments to irrigate the root,spraying on ridge surface and broadcasting on strip surface were 46.39%,23.21%,and 22.95% respectively. The control effects were 64.19%,59.74% and 50.22% respectively. The population declining rates for 20% fosthiazate FW and 10% fosthiazate GR were 42.67% and 29.89%,the control effects were 62.21% and 48.46% respectively. 41.7% Lufuda SC on root irrigation enhanced yield by 27.07% compared to water treatment.【Conclusion】For 41.7% Lufada SC,irrigation on roots method had much better effect in tomato root-knot nematode control than spraying on ridge surface,broadcasting on strip suface and all controls,increased yield significantly as well.
