Studies in the Eradication of Wild Morning‐Glory 1

"Wild morning glory" (Convolvulus sp.) is widely known in the United States and many parts of the Old World as a bad weed. Spots appeared in Utah more than a generation ago. No serious attention was paid to the weed before 1900, except in one or two localities where it had early become troublesome. By 1921, it had become so serious in several counties—notably Sanpete, Millard, Juab, and Davis—as to attract widespread attention. Agronomists believed that it could be controlled by vigorous cultivation, but many farmers and several farmers' organizations insisted that this was inadequate. Meanwhile, a wave of sentiment for spraying with sodium arsenite swept over the most populous parts of the state.
