Four herbicide (topik, puma super, granstar and derby) treatments at the recommended field dose (RFD) were applied for 5 weeks on wheat (Triticum sativum L. cv. Giza 168) crop. These selected herbicides are recommended to control two types (narrow and broad) of weeds in this crop. The growth parameter, oxidative stress defence system, nitrate reduction, proline level and protein contents were used to evaluate the toxic effect of these herbicides on wheat crop. The toxicity of herbicides used on this crop was as follows: puma super > topik > derby > granstar. The correlation between the herbicide concentrations and the activities of the antioxidant enzymes was monitored.
