摘要: 对采自四川省泸州市烟区的病原菌进行分离鉴定、致病性及菌丝融合群测定,并选用几种生物农药进行田间防治试验。结果表明,泸州市烟区烟草靶斑病是由瓜亡革菌[Thanatephorus cucumeris(Frank) Donk]、无性世代为立枯丝核菌(Rhizoctonia solani Kühn)的病原物引起,融合群鉴定表明该病原菌归入AG-3融合群。10%井冈霉素水剂、10亿CFU/g海洋芽孢杆菌可湿性粉剂和105亿CFU/g多粘·枯草芽孢杆菌可湿性粉剂对烟草靶斑病的防效较高,分别为77.08%、69.40%和63.75%。

Abstract: Isolation, identification, pathogenicity and mycelial fusion group determination of pathogenic bacteria collected from tobacco area of Luzhou, Sichuan province were carried out, and several biological pesticides were selected for field control experiments. The results showed that the pathogen was identified as Thanatephorus cucumeris (Frank) Donk, and its anamorph was Rhizoctonia solani Kühn. Observation for the mycelium fusion showed that all the isolates belonged to the anastomosis group 3 (AG-3). The control effect of Jinggang mycin 10% AS, Bacillus marinus WP and 10.5 billion CFU/g of mixture for Paenibacillus polymyxa and Bacillus subtilis WP were 77.08%, 69.40% and 63.75%,respectively.

Key words: tobacco target spot disease, pathogen identification, biological control
