Objectives:

  1. Evaluate ascospore detection of S. sclerotiorum using multiple Rotorod spore traps and monitor environmental conditions within snap bean fields to begin model development of ascospore absence or detection events.
  2. Evaluate the effects of several biofungicides on snap bean stand establishment and root rot severity.
