Abstract

Four herbicides were evaluated in a glasshouse pot experiment for their pre-emergence selectivity as soil surface sprays on 16 crop and 11 weed species of tropical or warm temperate regions. Maize and sorghum were each included in two sets, one of which was treated with seed dressings of safeners, l,8-naphthlic anhydride (NA) on maize, ad CGA 92194 on sorghum. Imazaquin and AC 263,499 gave very similar results which suggest useful selectivity against a range of annual grasses and amaranthus in soyabean, groundnut, pigeon pea, cow pea and mungbean. The perennials cyperus rotundus, c.esculentus, oxalis latifolia were also well suppressed and selective control may be possible in some large-seeded legumes. Safener provided considerable protection on both maize and sorghum bu selectivity was still inadequate in these or any other non-legume crop...
