Summary. Wheat and barley treated with the butoxyethyl ester of 2,4‐D at 2, 4 and 8 kg/ha (a.e.) at the jointing stage of growth were analysed for the amino‐acid composition of the protein of the grain. A slight decrease in the threonine and arginine, and an increase in the proline content of wheat protein were observed. In barley, only methionine showed a slight increase as a result of herbicide treatment. No significant difference in the amino‐acid composition of the protein was found in grain from hand‐weeded and un‐weeded plots. High doses of 2,4‐D may increase the protein percentage, but have only a very minor effect on the amino‐acid composition of the protein.
