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.
