Proceedings of the Consultative Group Discussion on Research Needs and Strategies for Control of Sorghum Root and Stalk Rot Diseases (Bellagio, Italy 27 Nov - 2 Dec 1983). — ICRISAT (International Crops Research Institute for the Semi-Arid Tropics), 1984. — 267 pp. Despite several decades of research, diseases remain a major constraint to sorghum production throughout the world. That was the reason ICRISAT and Texas A&M University cosponsored the first international workshop on sorghum diseases, hosted by ICRISAT at Hyderabad, India, in December 1978. It was also the reason for a second major international effort exactly 5 years later, by INTSORMIL and ICRISAT, to gain more understanding for better control of these diseases. This took the form of a highly specialized consultants' group meeting to make recommendations on the research needs and strategies for control of sorghum root and stalk rots.
Root and stalk rots are a group of diseases that reduce crop stands in the emergence and seedling stages, or most commonly cause stalk lodging in the postflowering and grain-filling stages of plant development. The improved high-yield potential varieties and hybrids under good management tend to be particularly susceptible to lodging induced by root and stalk rot. Although good progress has been made against other diseases of sorghum, research for control of root and stalk rots has been painfully slow. This is due to the complexity of the diseases themselves and the paucity of intensive interdisciplinary research on them.
