BIO-MANAGEMENT OF FUNGAL LEAF SPOT OF TOMATO (SOLANUM LYCOPERSICUM L.) USING INDIGENOUS TRICHODERMA ISOLATES

One of the main obstacles to feeding world is fungal leaf spot disease, which has a negative impact on plants' photosynthetic areas and significantly lowers crop quality output. To manage fungi that pose serious hazard both humans environment, various chemical fungicides are utilized. The goal current study was determine whether local isolates three Trichoderma spp. (Trichoderma viride, harzianum, asperellum) had any antagonistic effects in vitro against pathogenic Alternaria alternata, Fusarium solani, oxysporum, Aspergillus flavus, sydowii, sp. viride showed greatest growth inhibition all tested fungi, followed by harzianum asperellum. It shown species strongly inhibited mycelial pathogens. Compared other isolated alternata more, whereas oxysporum least amount observed. These findings imply can function as an effective biocontrol agent responsible for tomato disease.
