Physiology and Biochemistry Effects of Herbicides Sekator and Zoom on Two Varieties of Wheat (Waha and HD) in Semi-Arid Region

Aims: Herbicides are the most effective tool against the major weeds of cultivated plants, and are necessary in maintaining or increasing crop yields. However, most of these molecules are highly toxic for crop. Their massive and repeatly use can cause adverse effects on all components of the environment. The purpose of this study was to test the toxicity of two herbicides (Sekator and Zoom) on the physiology and biochemistry of hard wheat: Triticum durum Desf and common wheat: Triticum aestivum L in Tebessa. Both of the areas are considered as semi-arid zone of eastern Algeria.
