Abstract
Abstract The results of a series of replicated trials and of a series of commercial grower trials conducted in the United Kingdom during 1972 and 1973, established the effectiveness of difenzoquat (1,2‐dimethyl‐3,5‐diphenylpyrazolium ion) as the methyl sulphate as a selective post‐emergence herbicide for the control of wild oats in wheat and barley. Doses of 0.75 to 1.0 kg cation/ha applied at 200 or 400 litre/ha and at 2.1 or 3.5 kg/cm 2 gave good to excellent results when applied at crop growth stages 3 to 5 (Feekes—Large scale) for spring crops and at crop growth stages 4 to 6 for winter crops. In these experiments wild oats over a range of stages from 1st leaf to tillering were well controlled.
