Abstract:

In case of fungicidal trails all the treatments reduced the disease severity in comparison to unsprayed plots. The severity of disease after eight spray of Mancozeb @ 0.2 % was found minimum disease severity (5.0 %) followed by seven spray (6.0 %) and six spray (10.33 %), respectively. Maximum seed yield of 2000kg/ha was recorded with eight spray of Mancozeb @ 0.2% followed by seven spray (1922.22 kg/ha), and six spray (1902.77 kg/ha), respectively. Similar trend was recorded in case of test weight also. All the treatments avoided test weight loss of 5.70 to 21.81 %. Maximum being with eight and seven spray of Mancozeb @ 0.2 % (21.81 %) followed by six spray (21.67 %) and five spray (20.81 %).Maximum yield loss of 48.61 per cent was also avoided with eight spray of Mancozeb @ 0.2 % followed by seven sprays (46.53 %) and five spray (45.94 %).The maximum benefit cost ratio of 1:7.94 and 1:7.18 were obtained with four and three spray of Mancozeb @ 0.2 % followed by five sprays (1:6.82) and two spray (1:6.11).
