Mary Ann Hansen, Virginia Polytechnic Institute and State University. Should I Buy (or Retain) Stockers to Graze Wheat Pasture? 139 Agricultural Hall Bacterial wilt resistance was not associated with resistance to bacterial root invasion but with the capability of the plant to limit P. solanacearum colonization in the stem. the soil soon after harvest is complete to hasten decomposition of the debris.
