Brachiaria distachya may be used as soil-binder in erosion control and as a trap crop in sorghum ecosystems where it reduces population densities of shoot fly (Atherigona soccata) (FAO, 2010). It is considered as a weed in upland rice cultivations where it hosts several diseases, pests, parasites and viruses (Galinato et al., 1999). In Thailand, armgrass millet can be a reservoir for phytoplasma bacteria, the pathogen responsible for the white leaf disease in sugarcane (Wongkaew et al., 1997).
