绿僵菌生物菌剂对萝卜种蝇的田间防治效果评价
Field Evaluation of the Entomopathogenic Fungus Metarhizium anisopliae for Controlling the Radish Maggot(Delia floralis)
摘要
Abstract
To explore green control technologies against the Delia floralis on radish,a field experiment was conducted in a continuous radish cropping area in Hunan province using the'Baiyuchun'radish variety.The study investigated the control efficacy of Metarhizium anisopliae against D.floralis,focusing on its application dosage,application methods and its combination with chemical pesticides.The results indicated thatM.anisopliae had significant control efficacy against the incidence of D.floralis.In terms of application methods,the control efficacy of hole application and irrigation demonstrated extremely significantly better root formation rate(4.44%and 2.22%,respectively)than foliar spraying(44.44%).When application dosages of 100 mg or 150 mg per 667 m2 via hole application,the incidence were controlled at 6.67%and 4.44%,respectively,which were extremely significantly lower than those in the water control(41.11%)and the trichlorfon control of trichlorfon(30.00%).Furthermore,the combined application of M.anisopliae with chemical pesticides did not result in a significant improvement in root formation rate(5.56%)compared to M.anisopliae applied alone via hole application(3.33%).Therefore,considering cost-effectiveness,it is recommended to apply M.anisopliae with 100 mg per 667 m2 via hole application or irrigation for effective control of the D.floralis in practical production.关键词
