Evaluation Of Rhizoctonia Zeae As A Potential Biological Control Option For Fungal Root Diseases Of Sugar Beet, K M. Webb, R. M. Harveson, M S. West

Panhandle Research and Extension Center

Several common root diseases routinely damage sugar beet in Nebraska and other production areas of the Central High Plains, and it is becoming more common to find fields infested simultaneously with multiple pathogens. Owing to the shortage of available fungicides for economic management of soilborne diseases, alternative techniques such as biological control are increasingly being sought for disease management. Over the last several years, unidentified, sterile fungi have been isolated in conjunction with pathogens from infected sugar beet roots and seedlings. At least two promising isolates have been identified from in vitro assays that inhibit the radial growth of multiple …
