The effects of methionine treatment on damping-off caused by A. cochlioides in greenhouses, and the growth of hyphae and germ tubes in culture were studied. Application of 420-600 ppm methionine to seedlings 7 days after sowing resulted in significant reduction of infestation of sugarbeet plants by A. cochlioides in an artificially inoculated soil test. In zoospore inoculation tests, application of 200-600 ppm methionine one day before inoculation reduced the severity of damping-off.
