Abstract
High performance liquid chromatography was used to assess concentrations of hydroxamic acids in maize root extracts of 18 greenhouse-grown hybrids recommended in Ontario. On the basis of hydroxamic acid concentrations, low-level antibiosis against the western corn rootworm, Diabrotica virgifera virgifera LeConte was predicted for the majority of these (1990) hybrids, when grown under field conditions. Key words: Antibiosis, Chrysomelidae, Diabrotica, DIMBOA, hydroxamic acids, maize hybridsKeywords
