Abstract

Greenhouse trials were conducted to safe com (Zea mays) and reduce injuries effect of imazamethabenz-methyl, EPTC and metolachlor at three different field rates using potassium salt of Naphthalic Anhydride (NA) at four concentrations (0.3, 3, 15 and 30 mM) as new method of seed application in sandy soil. NA succeeds to protect com seedlings from herbicide injury even at 5 or 10 fold of the field rates of the herbicides. NA caused enhancement in both shoots and root length and fresh and dry weight. On the Other hand, the use of NA as safener in sandy soil protects the corn seedling from herbicides injuries by reducing peroxidase and increasing polyphenol oxidase activities.
