摘要:

为筛选防治烟草根结线虫病的有效药剂,本试验将25%阿维·丁硫水乳剂、11%阿维·噻唑膦颗粒剂、10亿孢子·g-1枯草芽孢杆菌·淡紫紫孢菌粉剂、25亿孢子·g-1厚孢轮枝菌微粒剂、100亿芽孢·g-1坚强芽孢杆菌可湿性粉剂等5种药剂施用于根结线虫病发病严重的地块,并开展田间药效试验。结果显示,11%阿维·噻唑膦颗粒剂处理45和90 d后,烟株根际土壤中的线虫减退率最高(54.80%和49.95%),发病率最低(2.41%和6.11%),防治效果最显著(84.14%和82.31%),且烟株农艺性状和根际土壤的理化性质几乎未受影响。此外,25亿孢子·g-1厚孢轮枝菌微粒剂处理后,烟株根际土壤的线虫减退率、烟株发病率和防治效果仅次于11%阿维·噻唑膦颗粒剂。综上,5种药剂中,11%阿维·噻唑膦颗粒剂和25亿孢子·g-1厚孢轮枝菌微粒剂对根结线虫病的防治效果最佳,且其对烟株生长和根际土壤理化性质的影响较小,可作为根结线虫病的防治药剂。

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-1Bacillus subtilis·Purpureocillium lilacinum powder,2.5 billion spores·g-1Verticillium chlamydosporiun,and 10 billion spores·g-1Bacillus 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-1Verticillium 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-1Verticillium 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.
