Abstract: | AbstractField surveys were conducted in 2014 and 2015 to determine the distribution and association of wilt incidence with biophysical factors. Spatio-temporal analysis of wilt epidemics in the farms revealed a wide distribution of the disease. Cropping year, district, cultivar, crop density, planting date, weeding, sucker and bud management, source of moisture and planting materials, presence/absence of wilt in neighboring farms, disease management practices, farmers awareness towards wilt diseases, planting date and cropping system were significantly associated with disease incidence in a multiple-variable model. A wilt incidence of ≤30% had high probability of association to good weed, sucker and male bud management practices, high level of farmers awareness towards wilt, low population density, disease-free suckers, rainfed production, absence of wilt in neighboring farms and good disease management schemes. Findings of this study showed Fusarium wilt is a major constraint and need for on-farm trainings to concerned bodies about wilt management schemes. |
