Sooty stripe is a serious disease of sorghum. Caused by a fungus called Ramulispora sorghi, it is particularly severe in areas with 500-1000 mm average annual rainfall. Recent studies indicate that sooty stripe can cause grain losses of nearly 50%. Scientists from several West African countries have joined forces with researchers from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) to find ways to halt the advance of the fungus. The work began in 1990 in Mali where ICRISAT's research team, the West Africa Sorghum Improvement Programme (WASIP) deliberately infected young sorghum plants with sooty stripe in order to detect resistance to the disease. This was done by spraying them with a suspension containing sooty stripe spores obtained from lesions of infected plants. In 1992 the effectiveness of the technique was confirmed by researchers from Burkina Faso's national programme, who modified the procedure by placing the fungal suspension in the whorls of leaves. This simple and cost-effective disease screening procedure is a practical option for research programmes lacking sophisticated laboratory equipment. In 1993, scientists from Burkina Faso, Mali and Niger, in collaboration with WASIP, intend to further refine the screening technique in their fight against the disease.
