Differences in sensitivity to glyphosate among weed species ? implication for weed control in HT maize

Original language description

A small plot field trial with Roundup Ready maize was carried out in the central part of Bohemia to a) compare the efficacy of various glyphosate treatments with conventional herbicides, b) describe the sensitivity of selected weeds to glyphosate, and c)evaluate the differences in weed biomass production under various herbicide treatments. Best herbicide efficacy was provided by a split application of glyphosate (1080 + 1080 g a.i ha-1.) and a tank-mix combination of glyphosate + acetochlor (1080 + 2100 g a.i. ha-1). However, obtained efficacy did not differ significantly from the efficacy of pre-mergence herbicides in most species. The most sensitive species to glyphosate was Amaranthus retroflexus L. (ED90 = 412 g a.i. ha-1) followed by Solanum physalifolium Rusby (475 g a.i. ha-1), Chenopodium album L. (677 g a.i. ha-1), Mercurialis annua L. (685 g a.i. ha-1), and Echinochloa crus-galli (L.) P.B. (1335 g a.i. ha-1). The highest suppression of the weed biomass (98.6 % and 99.4 % of
