Evaluation of New Herbicides against Mixed Weed Flora in Wheat

Field experiment conducted during the winter seasons of 1997–98 and 1998–99 revealed that sulfosulfuron 25 g+0.1% surfactant, isoproturon 1000 g and tank mixture of isoproturon+metsulfuron methyl 750+4 g ha⁻¹ provided satisfactory control of Avena ludoviciana, Phalaris minor, Chenopodium album, Melilorus indica, Anagallis arvensis and Lathyrus aphaca. Above herbicides gave 52–88% control of broad leaf weeds and 55–85% control of grassy weeds. Mon 48549 though provided excellent control of both type of weeds, but proved highly phytotoxic to wheat. Tank mix application of isoproturon and metsulfuron methyl (75+4 g h⁻¹) gave crop yield more or less similar to weed-free during both the years.
