Record low growing degree days and suboptimal growing conditions for corn in 2009 significantly delayed corn dry down and harvest in much of Wisconsin. As a result, near optimal environmental conditions (frost before full maturity) were present in the fall of 2009 for field mold growth. Field molds indentified on corn in the fall of 2009 by the University of Wisconsin Department of Plant Pathol...

Fifty 12,13-epoxytrichothecenes have been reported in the literature; of these diacetoxyscirpenol, T-2 toxin, nivalenol and vomitoxin have been naturally occurring in cereal grains throughout the world. Vomitoxin is produced in ears of corn prior to harvest when wet, cool weather precedes which favours Gibberella zeae growth. This type of infected corn, which often contains vomitoxin, is associ...

The biosynthesis of pyrrocidines, fungal PK-NRP compounds featuring a strained [9]paracyclophane, was investigated in Acremonium zeae. We used a synthetic L-tyrosine probe, labelled with oxygen 18 as a reporter of phenol reactivity and carbon 13 as a tracer of incorporation of this exogenous precursor. The ((18)O)phenolic oxygen was incorporated, suggesting that phenol behaves as a nucleophile ...
