摘要

[目的]评价5％香芹酚水剂对韭菜迟眼蕈蚊(Bradysia odoripahaga)田间防效,以及对韭菜生长安全性影响.[方法]以0.3％苦参碱水剂作为对照药剂,通过灌根方式考察5％香芹酚水剂对韭菜迟眼蕈蚊防治效果,并通过增产率和品质感官评价评估其对韭菜生产安全性.[结果]田间试验表明,在韭菜迟眼蕈蚊发生初期施药1次,药后3～14d,5％香芹酚水剂450.00 g(a.i.)/hm2、600.00 g(a.i.)/hm2处理对韭菜保株效果维持在49.10％～85.60％,药后21 d韭蛆虫口减退率和防治效果最高达76.26％和84.32％,对韭菜增产率达14.59％.[结论]5％香芹酚水剂对韭菜迟眼蕈蚊具有较好防治效果,对韭菜生长安全,可作为防治韭菜迟眼蕈蚊的绿色杀虫剂推广应用.

Abstract

[Objective]To evaluate the field control effect of 5％carvacrol AS on the chive maggot(Bradysia odoripahaga)and its impact on the growth safety of Chinese leek.[Methods]Using 0.3％matrine AS as control agent,the control effect of 5％carvacrol AS on B.odoripahaga was investigated through root irrigation,and its safety in Chinese leek production was evalua-ted through yield increase rate and sensory evaluation of quality.[Results]Field experiments showed that when applied once in the early stage of B.odoripahaga infestation,3-14 days after treatment,the protective effect on Chinese leek of 5％carvacrol AS at 450.00g(a.i.)/hm 2,600.00g(a.i.)/hm 2 was 49.10％-85.60％.After 21 d of treatment,the reduction rate and control effect of B.odoripahaga can reach 76.26％and 84.32％,and the yield increase rate of Chinese leek can reach 14.59％.[Con-clusion]5％carvacrol AS has good control effect on B.odoripahaga,and is safe for leek growth.It can be promoted and applied as a green insecticide for the prevention and control of B.odoripahaga.
