摘要

Heterocyclic changes in the chemical structure of existing herbicides may provide new options for weed management. Pyridine and pyrimidine analogues of dichlobenil were evaluated for weed control in ornamental production. All compounds were preemergently applied at 1, 5, and 10 kg/ha to large crabgrass (Digitaria sanguinalis), common purslane (Por-tulaca oleracea), and Japanese holly (Ilex crenata). The pyrimidine analogue, 4,6-dichloropyrimidine-5-carbonitrile, controlled large crabgrass and common purslane similar to the active ingredient in dichlobenil at 10kg/ha.
