Abstract
Castor is an important non-edible oilseed crop with diverse industrial value. India is a major producer of castor in the world. However, the productivity is low especially in the rainfed regions due to the incidence of pests and diseases. Fusarium wilt is the most destructive seed and soil borne disease in castor. The disease is seen in all the major castor growing states in India and can cause yield losses up to 80%. Though several management methods are available, host plant resistance is the most effective approach to manage the disease. Significant progress in identification of resistant sources and development of wilt resistant cultivars has been made in the past three decades. However, breakdown of resistance to wilt has been observed necessitating the development of durable resistance. In this article, the problems with castor production, incidence of wilt, management strategies and future outlook have been discussed.
