Cowpea and sunnhemp are the two potential cover crops to reduce #fallarmyworm population in maize field.
Two potential cover crops such as cowpea and sunnhemp have the potential to reduce the larval population of #fallarmyworm by lengthening the developmental time and increasing larval mortality. The other cover crops such as either corn or sorghum-sudangrass are two more preferred crops for the fall armyworm. Hence there is a potential to design a ‘push-pull’ strategy of FAW management by planting cowpea or sunnhemp inside the maize field as a ‘push’ crop, and ‘sorghum’ in the perimeter of maize field as a ‘pull’ crop. However, substantial additional research is needed to determine the influence of these crops on the population dynamics of fall armyworm in the maize field.
