Diphenyl ether herbicides

from Wikipedia, the free encyclopedia

The diphenyl ether herbicides , also phenol ether herbicides , are a group of herbicides that are chemically derived from diphenyl ether . Most of them inhibit protoporphyrinogen oxidase , which causes peroxide radicals to accumulate in the cell under the influence of light .
