The Synergistic Activity of Combination of Different Pesticides against Meloidogyne incognita (Root-Knot Nematode)
[Aims] The study aims to screen out the optimal pesticide agianst Meloidogyne incognita with high efficacy and low poison.[Methods] Dipping method was conducted to test the toxicity of 9 pesticides,after the screening,high active pesticides were mixed to test the joint toxicity.[Results] Emamecdn· benzoate had the highest toxicity against the second-stage juveniles (J2) and eggs with LC50 of 2.51,10.50 mg/L,respectively.The co-toxicity coefficient of emamectin·benzoate mixed with fosthiazate was 141.59,the cotoxicity coefficient of avermectin mixed with fosthiazate was 159.37.[Conclusions] The activity of emamectin· benzoate is the highest among the nine tested pesticides,the activity of fosthiazate mixed with avermectin or with emamectin benzoate are the best among all the mixtures.
