Abstract:
The study is aimed at determining the efficacy of fungicides and bioagents on management of S. rolfsii under field condition. In these studies, six different fungicides viz., mancozeb 75 WP, thiram 75 WP, tebuconazole 25.9 EC, carboxin 75 WP, carboxin (37.5%) + thiram (37.5%) WP, tebuconazole (50%) + trifloxystrobin (25%) WG and two bioagents (Trichoderma harzianum and Trichoderma viride) were tested against stem rot in field condition. Among the different treatments drenching with carboxin (37.5%) + thiram (37.5%) at 0.1 per cent at time of disease initiation was found most effective with lowest disease incidence (2.38%, 4.37% and 5.16%) at 60, 75 and 90 days after transplanting, respectively with maximum fruit yield (36.55 t/ha). Significantly followed by carboxin (75 WP) at 0.1 per cent and tebuconazole (50%) + trifloxystrobin (25%) at 0.1 per cent. While bioagents was found less effective as compared to fungicides treatments for management of stem rot of tomato.
