  1. Evaluate ascospore detection of S. sclerotiorum using multiple Rotorod spore traps and monitor environmental conditions within snap bean fields for model development of ascospore absence events.
  2. Evaluate biofungicide effects on snap bean stand establishment, root rot severity, and subsequent pod yields.
  3. Compare the efficacy of fungicides registered for white mold in snap bean.
