Objectives:

  • Examine pathogenic and beneficial microbial populations, as well as insect injury, associated with roots in historically lower-yielding sweet corn fields and compare to "new" corn plantings in close vicinity.
  • Examine abiotic factors in addition to pathogenic and beneficial microbial populations, as well as insect injury, associated with roots in sweet corn plantings exhibiting leaf-firing and those that have no evidence of leaf-firing, especially "new" corn plantings.
  • In greenhouse studies, examine soil from fields exhibiting leaf-firing and those that have no evidence of leaf-firing for soil microbial factors coupled with water stress to observe effects on root health and leaf-firing.
