strumarium, which is animal dispersed and the stolon-owning species Cyperus rotondus and Cynodon dactylon are important finger millet weeds. Measures to control weeds include cultural, physical, and chemical methods. Cultural methods could be sowing in rows instead of broadcast sowing to make distinction between finger millet seedlings and E. indica easier when hand weeding. ICRISAT promotes cover crops and crop rotations to disrupt the growing cycle of the weeds. Physical weed control in financial resource-limited communities growing finger millet are mainly hand weeding or weeding with a hand hoe. Diseases and pests Finger millet is generally seen as not very prone to diseases and pests. Nonetheless, finger millet blast, caused by the fungal pathogen Magnaporthe grisea (anamorph Pyricularia grisea), can locally cause severe damages, especially when untreated. In Uganda, yield losses up to 80% were reported in bad years. The pathogen leads to drying out of leaves, neck rots, and ear rots. These symptoms can drastically impair photosynthesis, translocation of photosynthetic assimilates, and grain filling, so reduce yield and grain quality. Finger millet blast can also infest finger millet weeds such as the closely related E. indica, E. africana, Digitaria spp., Setaria spp., and Doctylocterium spp. Finger millet blast can be controlled with cultural measures, chemical treatments, and the use of resistant varieties. Researchers in Kenya have screened wild relatives of finger millet and landraces for resistance to blast. Cultural measures to control finger millet blast suggested by ICRISAT for Eastern Africa include crop rotations with nonhost crops such as legumes, deep ploughing under of finger millet straw on infected fields, washing of field tools after use to prevent dissemination of the pathogen to uninfected fields, weed control to reduce infections by weed hosts, and avoiding of high plant densities to impede the pathogen dispersal from plant to plant. Chemical measures can be direct spraying of systemic fungicides, such as the active ingredients pyroquilon or tricyclazone or seed dressings with fungicides such as trycyclozole. Striga, a parasitic weed which occurs naturally in parts of Africa, Asia, and Australia, can severely affect the crop and yield losses in finger millet and other cereals by 20 to 80%. Striga can be controlled with limited success by hand weeding, herbicide application, crop rotations, improved soil fertility, intercropping and biological control. The most economically feasible and environmentally friendly control measure would be to develop and use Striga-resistant cultivars. Striga resistant genes have not been
