Integrated management of corn diseases using biological and natural products
2020
Haggag, W. M.
The problems of corn production caused severe losses of foliar diseases eg. streak, leaf blight, gray leaf spot and rust. The study was done to reduce disease incidence and increase the productivity of corn grown in the new reclaimed region. The application of biocontrol agents (Rhodotorula glutnis, Paenibacillus polymyxa, Bacillus subtilis, Pseudomonas putida, Trichoderma harzianum and Marin actimycete) and natural products (potassium silicate and amino acids eg. L-arginine-L-methionine, L-ornithine were clearly investigated. All biological products were actively antagonized the tested fungal pathogens which isolated from corn. Biological and natural products application are improved disease management, yield and quality. P. polymyxa and P. putida are significantly promoted the growth of corn. P. putida, P. polymyxa and natural compounds were proved to be effectively increased total phenols, total soluble protein, chitinase and peroxidase. The protection level of biological treatments in combination with application of natural products was as effective as the application of biological agents alone.
