Abstract: Coriander (Coriandrum sativum L.) is an important spices crop, grown in a wide range of weather conditions. Coriander suffers from various abiotic and biotic diseases. Among the biotic diseases, stem gall caused by Protomyces macrosporus is a major disease, which causes yield loss up to 33-36%. The experiments were conducted during 2016-17 at Vegetable Farm, Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) with eleven treatments viz., cow urine, cow dung slurry @ 10, 20 and 30% concentration of panchagavya, thiram @ 0.25%, carbendazim @ 0.2%, propiconazole @ 0.2% concentration and control. The effectiveness of organic treatments @ 30% concentration was significantly reducing the disease intensity. The maximum reduction was found 49.60% and 49.57% in panchagavya @ 30% concentration and minimum 17.61%, 26.88% in cow dung slurry @ 10% concentration during flowering and maturity stage respectively. In case of fungicides, the maximum disease control was recorded 51.70% at flowering stage and 49.71% at maturity stage treated with propiconazole @ 0.2% concentration. The maximum average numbers of chlamydospores were found at soil surface (198.80 g soil-1) and minimum in 2 inch depth (42.20 g soil-1) around the plant.
