Fall armyworm status and distribution: "Up to early June 2017, In Kenya, the pest has been reported in 27 of the 47 counties threatening more than 200,000 ha of maize crops. Ground control operations continued in all affected areas by farmers with assistance and coordination from the Ministry of Agriculture (MoA). It is worth noting that most of the infestations in Kenya were reported in the western and Rift Valley parts of the country which suggests that the pest might have migrated from Uganda." (USDA Foreign Agriculture Service, 2017). The forecast predicts that it will likely continue spreading further north into the western and the Rift Valley.
