dc.descriptionRadish (Raphanus sativus L., n=9), belongs to the family Cruciferae, is a popular and widely grown vegetable in Bangladesh as well as in the world and has multidimensional use. Radish is the third most important vegetable crop next to potato and eggplant, fifth most important vegetable seed crop next to onion, amaranth, eggplant and chili in respect of total acreage (44,000 ha) and first most important seed crop in respect of actual consumption (577 ton annually) of Bangladesh (Anon. 1997). At present 445 tons of radish seed are produced in 44 thousand hectors of land in the country. Total requirement of radish seed in Bangladesh is above 700 tons for vegetable purposes (Anon. 1997b). 48% locally produced and rest 52% imported from abroad (Rashid, personal interview, 2005). The cultivation of radish as seed crop has been becoming popular in the northern region of Bangladesh. Now a day this crop is cultivating year round.
dc.description.abstractIn the field experiment with the radish (cultivar Rocki), seed plants were sprayed with Rovral 50 W. P. (50 % iprodione) @ 0.2%, Dithane M-45 (80% mancozeb) @ 0.3% and Shincar 50 W. P. (50% carbendazim) @ 0.1% to control the Alternaria leaf blight of radish. Two sprays of each fungicide were done at 7-days interval starting from 24 days after transplanting of 40 days old stickling. Among the fungicides sprayed, Rovral was the most effective in controlling the disease and significantly reduced the leaf area infection (76%), number of spot per leaf (76.81%) and number of infected leaf per plant (62.97%) over the control followed by Dithane M-45 and Shincar. The fungicide Rovral 50 W. P. also increased the seed yield (48.42%), yield per plant (59.55%) and 1000 seed weight (23.50%) over control.
