Use of neem cake at 1kg + 100 gm of Trichoderma harzianum in 3kg FYM mixed for 7 days applied to soil before planting and watering regularly gave maximum yield (13.45t ha-1) and minimum disease incidence (5.5%), next best treatment was seed treatment with hot water 51°C + 100gm T. harzianum + 1Kg neem cake at sowing time gave disease incidence (6.75%) and yield (12.03t ha-1) both of treatments are statistically at par as regards in disease incidence and yield. The results showed that these safer management tools against diseases in ginger crop gave better protection and pesticide residue free rhizome because of its use as direct consumption without any processing.
