Abstract

Response of varying doses of tribenuron-methyl on weed control in wheat.

Abstract

Field experiments conducted during rabi 1992-93 and 1993-94 at Hisar, and 1993-94 at Karnal, India, in wheat fields (cv. WH-283) revealed that tribenuron-methyl (20 g/ha) provided excellent control of Chenopodium album, Melilotus indica, Anagallis arvensis and Rumex maritimus, but not of Lathyrus aphaca. The presence of weeds during the whole season reduced grain yields from 4684 to 3788 kg/ha, and from 5110 to 4014 kg/ha at Hisar and Karnal, respectively. Maximum grain yields were obtained in isoproturon-treated (1.0 kg/ha) plots at Karnal, and in tribenuron-methyl-treated (80 g/ha) plots at Hisar.
