Use of Atoxigenic Strains of A. Flavus to Manage Aflatoxin Contamination of Corn in Texas

Institutions
USDA - Agricultural Research Service
Start date
2007
End date
2010
Objective
  1. Follow Experimental Use Program for Corn once approved by U.S. Environmental Protection Agency.
  2. Experimental course initiated in 2006 will continue.
  3. The natural distribution of the atoxigenic strain within each treatment area in Texas will be determined as well as incidence of the high aflatoxin producing S strain.
  4. In new treatment areas, the behavior of soil applied wheat seed colonized by an atoxigenic strain of A. flavus will be determined.
More information
Approach: 1) Follow Experimental Use Program for Corn once approved by U.S. Environmental Protection Agency. 2) Treatment of cotton in several Texas areas and monitoring fungal communities on the treated cotton crop as well as on corn rotated to the cotton. 3) The potential importance of the S strain to aflatoxin contamination of corn in Texas will be assessed. 4) Influences of timing of application on efficacy of treatments will be sought. Producers will be asked about preferred application methods and timing and the practicality of atoxigenic strain use in the test areas will be assessed.
