Abstract
This study was conducted at Agricultural Research Institute, Tarnab, Peshawar in 1999-2000 to investigate the effects of S-Metolachlor (Dual Gold 960 EC) on weed control in different crops and the resultant effects on crop yields. Five vegetables, (onion, cauliflower, okra, peas and potato), and three agronomic crops (sugarcane, maize and sunflower) were used as test crops. S- metolachlor was applied to each of these crops as pre-emergent spray along with one or two standard herbicides for comparison when soil was at good water condition. In vegetables, except in potato, pendimethalin (Stomp 330-E) was used as standard. In potato, Topogard 500 FW (Terbuthylazine + Terbutryn) was also used as standard along with Stomp 330-E. In Sunflower, also Pendimethalin was used as standard. In maize, Primextra 500 FW and in sugar cane Gezapax combi 80 WP were used for comparison. S. Metolachlor, a new improved version of Metolachlor (Dual) proved very effective against most weeds except Convolvulus species giving 90% weed control. Yields of all crops were also significantly increased compared to weedy plots. Acceptable control of Cyperus species, which is hard to control with other herbicides, was also obtained.
