  1. Echinochloa

    Echinochloa is a grass genus, some of whose members are millets grown as cereal or fodder crops. The most notable of these are Japanese millet in East Asia, Indian barnyard millet in South Asia, and burgu millet in West Africa. Collectively, the members of this genus are called barnyard grasses, barnyard millets or billion-dollar grasses. When not grown on purpose, these grasses may become a nuisance to farmers. In particular, common barnyard grass is notorious as a weed. It is not easily suppressed with living mulches such as velvet bean. Early barnyard grass is a well-known example of Vavilovian mimicry: the plants have evolved to resemble rice, enabling them to escape weeding more easily. Among the plant pathogens that affect this genus are the sac fungus Cochliobolus sativus, which has been noted on common barnyard grass, and rice hoja blanca virus. Both affect many other grass species, in particular most important cereals, and Echinochloa weeds may serve as a reservoir. The fungi Drechslera monoceras and Exserohilum monoceras have been evaluated with some success as potential biocontrol agents of common barnyard grass in rice fields. More research is necessary, however, because they may not be host-specific enough to be of practical use.
