Abstract:
Survey was conducted for two consecutive years of kharif 2019 and 2020 in northern Karnataka to determine the severity of turcicum leaf blight of maize and pesticides usage by the farmer for the management of turcicum leaf blight. TLB is widely distributed in northern Karnataka in moderate to severe form. Five districts namely Belagavi, Dharwad, Haveri, Davangere and Uttar Kannada have recorded more than 40 per cent disease severity. The irrigated condition, black soil and dough stage of crop influences the disease severity. Few farmers used (Azoxystrobin 18.2% + Difenoconazole 11.4% SC) and emamectin benzoate 5 SG for the management of turricum leaf blight and fall armyworm respectively.
