Abstract
The efficacy of rimsulfuron (15 g ha-1 + 0.1% Sandovit as wetting agent) as single post-emergence application at 3–5 leaf stage of crop; metolachlor + atrazine (1800 + 1200 g ha-1), pre-emergence; and metolachlor + atrazine (900 + 600 g ha-1), as pre-emergence band spraying, on dominant weeds in two maize inbred lines (“OS 1-44” and “OS 36-16”) were studied at four sites in trials conducted from 1993 to 1995. Rimsulfuron showed good effect on Sorghum halepense (93% control), Echinochloa crus galli, Setaria spp., Amaranthus retroflexus and Chenopodium album (95% control). This herbicide controlled Sorghum halepense at 10–25 cm and at high dry weight of shoots (528 g nr-2) more effectively than the treatments that included atrazine. Rimsulfuron was less effective on Polygonum lapathifolium (63-86% control), Ambrosia artemisiifolia (62-73% control) and Abutilon theophrasti (42-60% control). The herbicide did not cause any visible phytotoxicity to the inbred lines. Seed yields increased as a result of all treatments from a weedy control value of 1.96 t ha1 to 2.74-3.28 t ha-1. Yield increase among herbicide treatments was in the following order: metolachlor+atrazine at the recommended rate> rimsulfuron>metolachlor+atrazine at a reduced rate.
