The horticulture department and Krishi Vignana Kendra had organised a demonstration of spraying pesticides in Narasipura in the wake of spread of blight disease for potato crop under Salagame hobli in the taluk recently.
At the demonstration aimed at preparing the farmers to check the disease, deputy director for horticulture Sakheel Ahmed said cloudy climate over the past week and increase in humidity has caused the disease. He said the disease, which spreads in the air up to 10 km a day, would only aggravate if the same climate continues.
