摘要
丹参根腐病是由腐皮镰刀菌侵染引起的一种土传病害,近年来在四川的田间发病株率平均为10%～30%,严重影响到丹参的产量和品质。采集不同生态环境的丹参根际土样进行分离,获得对腐皮镰刀菌有明显拮抗作用的哈茨木霉T23、桔绿木霉T56等一批菌株。田间试验表明,T23、T56对丹参根腐病的防效分别为52 3%和55 7%,与多菌灵的防效相当。
Danshen root rot is one of the soilborne diseases caused by Fusarium solani. In recent years, the average disease incidence varies from 10% to 30% in Sichuan province. It results in the yield reduction and the quality decline. In order to control this disease, many isolates of Trichoderma spp, which is effective to control Fusarium solani were selected from soils around danshen roots. Of these isolates, T.harzianum T23, T.citrinoriride T56 are more effective. The control effects of T23 and T56 to danshen root rot disease in field are 523% and 557%, respectively, and they are both equivalent to Carbendazol.
