Biological Control of some Weeds with Aqueous Extract of Wheat (Triticum aestivum L.)

Allelopathic effects of wheat aqueous extract were studied on seeds germination and seedling growth of four weeds Canary grass (Phalaris minor L.), Mallow (Malva rotundifolia L.), Sweet clover (Mililotus indica Mill), and Wild oats (Avena fatua), that shown seeds germination and seedlings growth of all weed species were inhibited with in all treatment of Wheat (Triticum aestivum L.) residues at concentration 5, 10, 15% on germination and early seedling growth of weeds, results showed the inhibitory effect of aqueous extract of wheat was hat higher 5% of EWC (%). from results that Mallow was more sensitive for treatments, While the less sensitive was Canary.
