Control Effect of Abamectin Combined with Fluopyram on Meloidogyne incognita Chitwood in Cucumber Production
A field experiment was conducted to evaluate the control effect of abamectin combined with fluopyram on the cucumber root-knot nematode Meloidogyne incognita Chitwood and determine the appropriate application amount.Six treatments were designed,including abamectin·fluopyram 60%water dispersible granules with different doses,abamectin 0.5%granules,fluopyram 41.7%suspension concentrate,and water control.The control effects and cucumber yields were compared between different treatments.The results showed that the root irrigation with abamectin·fluopyram 60%water dispersible granules for transplanted cucumber seedlings after field adaptation had a good control effect on the cucumber root-knot nematode disease.Specifically,the control effect was 79.26%-82.66%75 days after application and 75.36%-78.47%at the harvest stage.The combined agents were safe for cucumbers,and the yield in this treatment was significantly higher than that of the control.The recommended application amount of abamectin·fluopyram 60%water dispersible granules was 540.0-720.0 g.a.i./hm2.
