Abstract
Four herbicides were evaluated as surface pre-emergence treatments in a glasshouse pot experiment on 28 warm-climate crop and weed species. Maize and sorghum were each included in two sets, with and without seed dressings of safeners, 1,8-naphthalic anhydride (NA) on maize, and CGA 92194 on sorghum. Metazachlor was very much more active than RST 20024H but both showed the effects and selectively typical of the anilide herbicide group with excellent selectivity against Amaranthus retroflexus and a range of annual grasses in large-seeded legume crops. Maize and sorghum showed moderate tolerance which was markedly increased by the respective safeners. Cyperus esculentus, commelina diffusa and Rottboellia cochinchinensis were only controlled at the higher doses of each compound and advantages over the established members of this herbicide group are not clear
