Application of Trichoderma Hz36 and Hk37 as Biocontrol Agents against Clubroot Caused by Plasmodiophora brassicae.

ABSTRACT: Clubroot, a soil-infective disease caused by Plasmodiophora brassicae, is a serious disease affecting cruciferous plants around the world. There is no effective control measure to completely remove this pathogen from fields after infection. Here, we screened and identified two strains (Hz36, Trichoderma guizhouense; Hk37, Trichoderma koningiopsis) of Trichoderma from the gall of clubroot in rapeseed fields with biocontrol potential for clubroot. The fermentation broth of Hz36 could significantly inhibit the germination of resting spores of P. brassicae, and promote the seed germination and root growth of rapeseed. The biocontrol efficiency of Hz36 strain on clubroot for rapeseed and Arabidopsis thaliana was 44.29% and 52.18%, respectively. The qPCR results revealed that strain Hz36 treatme
