N2 - The herbicide ethofumesate is commonly used in onion fields in Israel. Experiments with four onion cultivars have shown the combination of a pre‐emergence treatment with ethofumesate and foliar application of a variety of herbicides to cause a marked decrease in plant fresh weight. This effect of ethofumesate was still evident when post‐emergence herbicides were applied as late as the third leaf stage of development. Significantly lower amounts of waxes were extracted with chloroform from the leaves of onion plants treated pre‐emergence with ethofumesate, at the rates of 0.2–0.8 kg/ha. SEM micrographs showed considerable changes in the onion epicuticular fine structure following these ethofumesate treatments. Furthermore, a significant increase in the penetration of 14C‐labelled compounds into the onion leaves was measured. The possible implications of ethofumesate effects on onion leaf surface fine structure, are discussed.
