5种不同药剂对烟草根结线虫病的防治效果评价
Evaluation of the control effect of 5 different pesticides on tobacco Meloidogyne disease
摘要
Abstract
To screen effective pesticides for controlling tobacco Meloidogyne disease,in this experiment,five varieties of pesticides,namely 25%abamectin·carbosulfan emulsion,11%abamectin·thiazole granule,1 billion spores·g-1 Bacillus subtilis·Purpureocillium lilacinum powder,2.5 billion spores·g-1 Verticillium chlamydosporiun,and 10 billion spores·g-1 Bacillus firmus wettable powder,were applied to plots with severe Meloidogyne disease,and the field efficacy trials were carried out.The results showed that after treatment with 11%abamectin·thiazole granule for 45 and 90 days,the reduction rate of nematodes in the rhizosphere soil of tobacco plants was the highest(54.80%and 49.95%),the incidence rate was the lowest(2.41%and 6.11%),and the control effect was the most significant(84.14%and 82.31%).Moreover,the agronomic traits of tobacco plants and the physical and chemical properties of rhizosphere soil were almost unaffected.Besides,the nematode reduction rate,incidence rate and control effect of tobacco rhizosphere soil treated with 2.5 billion spores·g-1 Verticillium chlamydosporiun were only inferior to 11%abamectin·thiazole granule.In summary,among the five varieties of pesticides,11%abamectin·thiazole granule and 2.5 billion spores·g-1 Verticillium chlamydosporiun had the best control effect on Meloidogyne disease,and the dosage does not affect the growth of tobacco plants and the physicochemical properties of rhizosphere soil,which can be used as insecticides for the prevention and control of Meloidogyne disease.关键词
