Influence of tank mixture of isoproturon and fluroxypyr on the control of weeds in wheat (Triticum aestivum)

A 2-year field study conducted at Hisar during 1989-90 and 1990-91 indicated that fluroxypyr was more effective against wild pea (Lathyrus aphaca L.) than lambsquarter (Chenopodium album L.), while 2, 4-D and isoproturon were more effective against lambsquarter than wild pea. Tank mixture of fluroxypyr 0.20 kg/ha + isoproturon 0.75 kg/ha applied 30 days after sowing provided effective control of grasses and broad-leaf weeds in wheat (Triticum aestivum L. emend. Fiori & Paol.) and gave grain yield at par to that obtained in weed-free check.
