Effect of Doses and Stages of Application of Isopropagyl on Phalaris minor in Wheat

Isopropagyl applied at 20 days after sowing recorded 78 to 90% control of Phalaris minor. Isopropagyl at 125 and 150 g ha⁻¹ provided better control of Phalaris minor than at lower rates. Grain yield of wheat increased with the successive increase in the doses of isopropagyl irrespective of stages of application.
