M. College of Agriculture, NAU, Navsari in 2004 to find out suitable management strategies. It is difficult to control F. solani as it is having soil inhabiting nature. This led to trials on the use of organics to control the pathogen. The extracts of different organics of neem cake, mustard cake, FYM, groundnut cake, poultry manure, press mud, castor cake and coconut cake were tested against F. solani by poisoned food technique in in vitro. Least growth of the pathogen was recorded in the extracts of neem cake showing excellent inhibitory effect i.e 59.8 % against F. solani. Next best in order of merit was mustard cake (52.61 %) followed by FYM (49.40 %), groundnut cake (44.80 %), poultry manure (42.29 %), and least by other cakes.  Chilli, Fusarium solani,organic extract, Wilt.  Chilli (Capsicum frutescens L.) is one of the most important vegetable crop grown in India for the value of its fruits in making spice and condiments. India is one of the major chilli growing countries, producing 9.21 lakh tonnes of ripe dry chillies with an area of 8.92 lakh hectares 1 .In Gujarat, the area under chilli crop is about 27,110 hectares with an annual production of about 24,570 metric tonnes of red dry chillies 2 . The area is mostly distributed in Anand, Kheda, Himmatnagar, Surat, Navsari and Valsad districts. In south Gujarat the crop is grown in an area of 2200 hectares mainly for green chillies during post rainy seasons.Chilli is attacked by several fungal diseases. During the survey, chilli crop was found severely affected by wilt at Navsari and surrounding villages. It was also found at vegetatable research farm Looking to the seriousness of the disease present investigation was undertaken to manage the disease by use of organics due to soil borne nature of the pathogen.    The aqueous extracts of different organic materials viz., neem cake, mustard cake, FYM, groundnut cake, poultry manure, press mud, castor cake and coconut cake were prepared by suspending 30 g of each organic material in 150 ml
