Additive effects of Trichoderma isolates for enhancing growth, suppressing southern blight and modulating plant defense enzymes in tomato.

ABSTRACT: Southern blight, caused by Sclerotium rolfsii, poses a significant economic threat to tomato cultivation. This study involved the isolation, characterization, and evaluation of three selected Trichoderma isolates (Tri2, Tri3, and Tri6), applied individually and in combination, for their potential to promote plant growth and suppress southern blight under both in vitro and in vivo conditions. These isolates exhibited multiple plant growth-promoting traits, including cellulase, protease, amylase, lipase, catalase, and phosphate-solubilizing activities. Furthermore, they performed as efficient antagonists, inhibiting the mycelial growth by up to 88.8% and the oxalic acid production of S. rolfsii by up to 81.9%. The Trichoderma isolates significantly enhanced tomato seed germination and seedli
