Effects of root diffusates of some weeds associated with corn plantations on the hatchability of the corn cyst nematode, Heterodera zeae
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 68 (6), 135-136
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.
All tested weed root diffusates (WRD) successfully stimulated the hatchability of the cysts, but less than CRD did except the root diffusates (RD) of Rumex dentatus which failed to stimulate the nematode cysts.
As for the summer weeds, RD of Echinochloa colonum was the most effective treatment, followed by Chenopodium album, Malva parviflora and Portulaca oleracea. While, RD of Beta vulgaris, Convolvulus arvensis and Solanum nigrum had the lowest effect.
As to the winter weeds, RD of Melilotus indica was the most effective treatment followed by Lolium multiflorum and Brassica kaber; whereas, RD of Rumex dentatus failed to stimulate the hatchability of the nematode cysts.
