LIQUID COATING FORMULATION CONTAINING SOLID PARTICULATE MATERIALS TO INCREASE EFFICACY OF BIOLOGICAL TREATMENTS WITH BENEFICIAL MICROORGANISMS

摘要

Seeds having a continuous, adhered coating comprising in combination a microorganism for biological control of plant pathogens and a carbonaceous particulate solid matter including soft coal, lignateous shales, sphagnum moss, muck soil, activated charcoal or mixtures protect the seed and plant from soil-borne pathogens including Pythium spp. Bioprotective compositions comprising Trichoderma strain 22 (ATCC No. 20847) are particularly effective in protecting a variety of crops including tomato, cucumber, cabbage, sugar beets, table beets, field corn, sweet corn, cotton, dry bean, snap bean and soybean.
