Effectiveness of Different Rates of Post-emergence Herbicides in Wheat (Triticum aestivum L.)

Afia Majeed, M. Sadiq and M. Hussain    

Abstract: Two herbicides namely Logran and Tolkan were evaluated at three different rates i.e., low, medium and high on Inqulab and Pasban varieties of wheat (Triticum aestivum L.). The results showed that herbicide activity index value was maximum with high rates and minimum with low rates of herbicides. Significant improvement was recorded in various morphological and yield components of wheat by low and medium rates while high rates caused detrimental effect. Recommended rates of both Logran and Tolkan produced about 37% greater grain yield than weedy check which was almost equal to hand weeding. Two varieties exhibited non-significant difference for various parameters.
