摘要
二化螟是为害水稻最严重的常发性害虫之一。在水稻秧苗期和本田期,使用氯虫苯甲酰胺进行防治水稻二化螟试验。结果表明,在水稻秧苗移栽前5 d施用1次20%氯虫苯甲酰胺悬浮剂(带药移栽),对水稻生长和非靶标生物安全,秧苗素质指标提升,可有效控制和延迟本田期1代二化螟为害,应用效果优于对照药剂阿维菌素。其中,制剂用量100 mL/667m^2和150 mL/667m^2两处理对二化螟的防效达100%,并可持续45 d,药后60 d防效仍在93%以上。在本田期水稻破口前,再次施用该药,可有效防治2代二化螟,并具保穗效果。
Chilo suppressalis(Walker)is one of the most serious pests of rice.In this study,rice C.suppressalis control experiments were carried out with chlorantraniliprole SC application at the seedling and paddy field stage.The results showed that applying 20%chlorantraniliprole SC 5 days before transplanting was safe to rice growth and non-target organisms,and could enhance the quality of the rice seedlings.In this way,the damage of the first generation of rice C.suppressalis in the paddy field could be effectively controlled.The treatments with dosages of 100 m L/667 m^2 and 150 m L/667 m^2 could manage C.suppressalis for 45 days with a control efficiency of 100%,and it can still be more than 93.21%on the 60 thday after the application.An additional application of 200 g/L chlorantraniliprole SC before the rice break stage could effectively control the second generation of rice Chilo suppressalis(Walker)and protect the panicle.
