四唑虫酰胺对水稻稻纵卷叶螟的防治效果

Control Effect of Tetraniliprole on Cnaphalocrocis medinalis

以本地常用的5%阿维菌素EC和200 g/L氯虫苯甲酰胺SC作为对照药剂,研究了拜耳公司生产的200 g/L四唑虫酰胺SC 8、10 mL/667 m^(2)对稻纵卷叶螟的田间防效。结果表明,施药后7 d,四唑虫酰胺SC 10 mL/667 m^(2)对稻纵卷叶螟的杀虫效果最好,速效性显著优于对照药剂氯虫苯甲酰胺和阿维菌素,药后14 d其杀虫效果达100%,保叶效果达92.18%,均显著高于阿维菌素,杀虫效果与氯虫苯甲酰胺相当,保叶效果比氯虫苯甲酰胺略优,并且对水稻安全。

Avermectins 5% EC and chlorantraniliprole 200 g/L SC that are commonly used locally were applied as the control agents.This paper studied the field control effects of the 200 g/L tetraniliprole SC produced by Bayer company on Cnaphalocrocis medinalis at the dosages of 8,10 m L/667 m^(2).The results showed that after the 7 d application,tetraniliprole SC 10 m L/667 m^(2)had the best insecticidal effect against C.medinalis,and its quick-acting effect was significantly better than the control agents.The insecticidal effect was 100% and the leaf-preserving effect was 92.18%after 14 d application.The both of the effects were significantly higher than avermectins,and the insecticidal effect of tetraniliprolewas similar to that of chlorantraniliprole,while the leaf-preserving effect was slightly better than chlorantraniliprole,which it was safe to rice.
