| Abstract:
Soil solarization with transparent polyethylene mulch (25 µm) for 40 days during June-July was found effective for the control of collar and root rot of strawberry caused by Sclerotium rolfsii. Mulching of the irrigated plots with the polyethylene sheet resulted in 10.6°C (2001) and 10.0°C (2002) higher temperature at 7 cm soil depth with an average maximum temperature of 39.6 and 40.9°C, respectively. Soil solarization for 40 days completely inhibited the germination of sclerotia of the fungus buried before solarization at 7 cm soil depth. Three set of treatments i.e. drenching, root dip + drenching with different fungicides and root dip of strawberry runners in different fungicides followed by their plantation in solarized plots, were tested for the management of the disease. Among different treatments of the three sets, root dip of strawberry runners in combination fungicides containing carbendazim 12 % + mancozeb 63% (0.2 %) or thiophanate methyl (0.1 %) followed by their plantation in solarized plots was found most effective with the plants recording no incidence of the disease. | |
