文摘

Four fluorine-containing cyclophosphonates derivatives and twenty eight fluorine-containing alkylphosphonates were synthesized. Further study the relationship of structure-herbicidal activity. Some target compounds exhibited high herbicidal activity at 75 g ai/ha. Compounds III-3, III-4 and III-8 were selected for a broad spectrum test. Compounds III-4 and III-8 were comparable with glyphosate against all of the tested weeds at a rate of 75 g ai/ha.
