Management of wilt disease caused by Fusarium oxysporum f.sp. ciceri in chickpea

摘要

Field experiment as well as lab experiment were conducted for two years to find out effective fungicides for control of wilt disease in chickpea. Carbendazim+ thiram (1:2) and carbendazim proved to be most effective in inhibiting cent per cent growthof the test fungus at the concentrations of 250 and 500 ppm, respectively followed by thiram (500 ppm) and carboxin + thiram (500 ppm). Next effective fungicides in order were tabuconazole (500 ppm), carboxin + thiram (250 ppm), thiram (500 ppm). In field experiment, all the fungicides as seed treatments reduced the wilt disease incidence significantly over untreated check during both the years. In different treatments, disease incidence varied from 11.00 to 19.67 and 10.63 to 16.70 as against 45.67 and42.17 percent in check in 2014-15 and 2015-16, respectively. However, seed treatment with carbendazim+ thiram (1:2) @ 2g/kg seed provided the maximum seed germination (82.33 and 80.00 per cent), minimum disease incidence (11.00 and 10.63 per cent) and maximum grain yield (1366.67 and 1366.67 kg/ha) closely followed by carbendazim and thiram during both the years.
