茶麸对菜心和小白菜细钻螺的田间防效研究

Research on Field Control Effect of Tea Bran Against Opeas gracile in Brassica campestris L. ssp. Chinensis var. paachinensis and Brassica campestris L. ssp. Chinensis

基于细钻螺的习性和茶麸的药性作用,并结合民间防治方法,本文以茶麸为试材,研究了其不同浓度和不同施用方式对菜心和小白菜细钻螺的防治效果。结果表明,蔬菜定植后根部撒施茶麸45 kg/hm^(2)的防治效果与常规化学药剂相当。说明茶麸是一种非常理想的化学杀螺剂替代物,其在蔬菜上的应用有助于农药“减药”目标实施,也大大提高了农产品的食用安全性。

Based on the habits of Opeas gracile and the medicinal effect of tea bran, comb ined with folk control methods, this paper studied the control effects of tea bran against Opeas gracile in Brassica campestris L. ssp. Chinensis var. paachinensis and Brassica campestris L. ssp. Chinensis with different concentrations and application methods. The results showed that the control effect of spreading tea bran 45 kg/hm2in the root of vegetables after transplanting was equivalent to that of conventional chemical molluscicide. It shows that tea bran is a very ideal substitute for chemical molluscicide. Its application in vegetables not only contributes to the implementation of the "drug reduction" goal of pesticide, but also greatly improves the edible safety of agricultural products.
