Biocontrol of Fusarium Wilt in Tomato Plants using Bacillus subtilis S37-2 and Pseudomonas sp. GHR1-1

Abstract

The control effect of tomato wilt disease was investigated using the strain developed by Rural Development Administration. As a result, Bacillus subtilis S37-2 and Pseudomonas sp. GHR1-1 showed an inhibitory effect on mycelial growth and spore germination of Fusarium oxysporum f sp. lycopersici. The control effects of wilt disease in tomato seedlings showed that the disease severity was lower when the strains were treated in the sowing stage than in the two-leaf stage. In the sowing stage, the control effect of the tomato wilt disease was 94.6% when GHR1-1 was treated, and 87.1% when the GHR1-1 and S37-2 were mixed. These results suggest that the two strains may be used as environmentally friendly microbial agents.
