Corn seeds coating by copper sulfate and sodium silicate salts exhibited non phytotoxic and led to reduce late wilt disease infection percentage under field nursery conditions during two tested seasons of 2017 and 2018 compared to control treatment. A fertilizer by 5-25 gm. of these salts added with first and second irrigates separately to corn seedlings led to retarding of late wilt disease in the field and caused reduction of infection percentage with the most salts tested cons. Reduction of the disease as salts application resulted in enhancement of yield especially with high cons .Increasing of salts cons led to increase the retarding of late wilt disease and reduction of infection percentage. Generally, Copper sulfate was more effective against late wilt disease than sodium silicate and recorded high retarding of disease and the highest enhancement of the yield in comparison of control and other treatments. Induction of peroxidase and polyphenol oxidase enzymes synthase by salts application may be have role in retarding late wilt disease followed by increasing of chemical compounds of fat, ash and carbohydrates contents while antioxidant and total phenols did not effected .
