The researchers are assessing some promising microbial strains in greenhouse experiments for their ability to control a range of diseases. When wheat heads were treated with bioprotectant bacteria before they were sprayed with Fusarium spores the plants showed fewer diseased grains with significantly lower levels of contamination by vomitoxin than did nonprotected plants. Application of the bio-protectant strains to cereal crop seeds promoted the germination of seeds in soil to the same extent as treatment with chemical fungicides. Initial tests in Brazil indicate that the biocontrol strains are also effective in controlling disease under field conditions. Friedlander, B. P. 1997.
