According to a recent study carried out by the International Institute of Tropical Agriculture (IITA) station in Benin, farmers consider cogon grass
According to a recent study carried out by the International Institute of Tropical Agriculture (IITA) station in Benin, farmers consider cogon grass (Imperata cylindrica) to be the most damaging weed for their crops. In places where it thrives, yields are reduced by up to 80% for all food and forage crops and even for trees such as palms. Cogon grass deprives vegetables of light and nutrients and damages tubers by piercing them with its rhizomes. It spreads very quickly in some cases, it can grow up to 40 t/ha. Simple hoeing is an ineffective approach to eradication of this weed which can grow back from a fragment of just 2 mm. In a bid to tackle this invasive species, the IITA is planning to use biological control and has selected six species of pathogenic fungi which are natural enemies of the Imperata.
