摘要

Strawberry (Fragaria ananassa) is an important fruit crop that grows well in temperate and tropical climates. Fusarium wilt is one of the major soil borne diseases of strawberry plants resulting in significant yield losses. Due to the high residual effect of chemical fungicides and direct consumption of fruits, disease management through fungal and bacterial biocontrol agents paves the way for sustainable, eco-friendly and effective plant disease management. Therefore, the present work was undertaken to test different species of indigenously isolated and characterized Trichoderma spp. and plant growth-promoting microorganisms (PGPM) against Fusarium oxysporum f. sp. fragariae in vitro and in vivo. All the microbial antagonists tested were able to inhibit the growth of F. oxysporum f. sp. fragariae. Therefore, the best bioagents were tested in vivo. In the present study, Trichoderma harzianum and the Bacillus subtilis + Pseudomonas chlororaphis consortium inhibited the growth of F. oxysporum f. sp. fragariae. A combination of P. chlororaphis and T. harzianum was significantly superior at managing wilt in vivo, and it also enhanced the plant growth parameters. Therefore, based on these findings, it was concluded that a consortium of biocontrol agents was effective against wilt pathogen of strawberry and could be utilized for chemical-free sustainable farming.
