Effects of root diffusates of some weeds associated with corn plantations on the hatchability of the corn cyst nematode,Heterodera zeae

Abstract

Twenty two summer weeds belonging to fifteen plant families and twelve winter weeds from eight plant families were tested to compare the effects of their root diffusates with the corn root diffusates (CRD) of cv. Giza 2 on the hatchability of the corn cyst nematode (CCN),Heterodera zeae.
