Evaluation of Difenoconazole along with Macronutrients Spray for the Control of Brown Leaf Spot (Bipolaris oryzae) Disease in Rice (Oryza sativa) Crop

The study pertaining to the control of brown leaf spot (BLS) disease on rice crop by using different combinations of fungicide (difenoconazole) with various concentrations of sprayable formulations of macronutrients (NPK) was conducted during Kharif 2012 to 14 at Adaptive Research Farm, Gujranwala, Pakistan. The experiment was conducted on a promising basmati rice cultivars Super basmati in RCBD with three repeats. The spray of difenoconazole at rate of 315 mlha^-1 + 500gha^-1 of NPK (20:20:20) significantly decreased incidence of BLS per leaf (9.31) and resulted in significant increase in 1000 grain weight (22.54 g) and yield (3.57 tha^-1) and gave an additional income of Rs.26305 ha^-1 with benefit cost ratio of 11.31 compared with control. It is suggested that spray of difenoconazole and macro nutrients (NPK) at appropriate concentrations are handy to minimize incidence of BLS disease in rice crop.
