The Effect of Dehydration and Shefaleer Herbicide Spraying Date to Control Some Weeds

Abstract

The study conducted to know the effect of dehydration on Raphanusrapnanistrumgrowth as broad leaf weed and wild barely as leaf weed addition to study the effect of Shefaleer herbicide as integrated with three dehydration periods which included 3,6 and 9 days besides control treatment and two stages of spraying herbicide. The results showed that the Shefaleer herbicide had highefficiency in Raphanusrapnaistm-n control but this herbicide didn’t show any effect on wild barely. The results also indicated that the plant exo exposures to dehydration periods caused significantly in creates of amine acid content and cytoplasmic membrane signal damage so the results also showed significantly in creases of propene amino acid content and cytoplasmic membrane signal damage so the results also showed significantly decreases in chlorophyll total content according that in treatment control.
