5种阿维菌素·氟吡菌酰胺复配制剂对温室黄瓜根结线虫防效研究

Study on the Control Effect of Five Compound Formulations of Abamectin and Fluopyram against Green-House Cucumber Root-Knot Nematodes

为明确5种阿维菌素·氟吡菌酰胺复配制剂以及2种单剂阿维菌素和氟吡菌酰胺对温室黄瓜根结线虫的防治潜力,本文采用春季温室黄瓜灌根方式施用7种杀线虫剂单因素随机区组试验,研究了施药后30 d和60 d的黄瓜根结线虫发病株率、病情指数、防效以及收获的黄瓜总产量。结果表明:与空白对照相比,7种杀线虫剂对黄瓜根结线虫均有较好的防效,药后30 d的防效为67.00%~81.08%,药后60 d的防效为70.94%~88.66%,增产率为29.42%~54.68%。本试验为5种阿维菌素·氟吡菌酰胺复配制剂在施药时间、施药方式、剂型等方面防控根结线虫提供了理论支撑。In order to determine the control potential of five compound formulations of abamectin and fluopyram and two single nematicides of abamectin and fluopyram against green-house cucumber root-knot nematodes, this paper used a single-factor randomized block experiment to study the diseased plant rate, disease index and control effect, as well as the harvested total cucumber yield of seven nematicides on the green-house cucumbers after the root irrigation of 30 d and 60 d in spring. The results showed that compared with the blank control, seven nematicides had a good control effect on cucumber root-knot nematode and the control effects of the root irrigation of 30 d and 60 d were 67.00%~81.08% and 70.94%~88.66%, respectively. And the total yield increase rate was 29.42%~54.68%. This study provides atheoretical support for five compound formulations of abamectin and fluopyram to control root-knot nematode in terms of application time, application method and dosage form.
