| dc.description | Tomato (Lycopersicon esculentum) is one of the most popular and widely grown
vegetables in Bangladesh. It is the third most important vegetable crop of
Bangladesh in term of area (15788.47ha) and production (137 thousand ton), but
seven in position in. respect of production, where as potato is the highest
(Anonymous, 2007). The average yield of tomato is 7.9mt/ha which is far as
compared to the average yield of tomato in other countries. | en_US |
| dc.description.abstract | A study was carried out in the laboratory and under field condition to find out the
effectiveness of Trichoderma harzianum as a boiagent for controlling collar rot
(Sclerotium rolfsii) of tomato. The pathogen was collected from naturally infected
tomato plant and isolated by tissue planting method. Fomulated Trichoderma
harzianum was collected from IPM Laboratory, Department of Plant Pathology,
Bangladesh Agricultural University, Mymensingh. The 7richoderma harzianum
showed excellent effect in controlling collar rot disease of tomato in field
experiment. The maximum emergence of lesion size (9.003 mm) was observed in
tomato plants inoculated with only S. ro/fsii. The minimum emergence of lesion
size (2.900 mm) was observed in bio-fungicide treated plots. The highest total
mortality (61.11%) was recorded in S. rolfsii inoculated plots and the lowest
(24.07%) was in bio-fungicide treated plot. The plant height, number of
inflorescence, number of branches and number of fruits per plant were the highest
in bio-fungicide treated plots, while the minimum in S. rolfsii inoculated plots.
Trichoderma harzianum treated plots resulted the highest yield performance
(27.23ton/ha) as compare to Sclerotium rolfsii inoculated plots (10.28 ton/ha). | en_US |
