The effect of spraying of wheat straw extracts and some herbicides on controlling some weed species

الملخص EN

This study was designed to investigate the effect of spraying wheat straw aqueous extracts with two common used herbicides for controling broad and narrow leaf weed plants in wheat fields in the region.

The study consisted of five treatments; wheat straw aqueous extract; grass weeds herbicide clodinafop-propargyl (Topik); broad leaf herbicide tribenuron-methyl (Granstar); zero control (no herbicides were applied) and zero – weed ( Wheat pure stand) treatments, chlorophyll a, b and total chlorophyll were indicated for all treatments after 48 hours from herbicide application.

Results illustrated significant differences between all treatments, minimum wheat yield was recorded in zero control plots then plots that was treated with wheat straw aqueous extracts, Broad leaf weed herbicide (Granstar), narrow leaf weeds herbicide (Topic) and maximum yield was recorded with zero weed treatments.

This study elucidate the potentiality of using wheat aqueous extracts for controlling some weed plants due to its obvious effect on reducing the weed plants height and the levels of chlorophyll a, b and total chlorophyll in treated wheat plants
