Practical Weed Science for the Field Scout: Corn and Soybean
Radish, wild (Raphanus raphanistrum)
Winter annual broadleaf
Usually a winter annual or biennial weed of agronomic crops, forages, nurseries and horticultural crops found throughout the United States. Leaves initially develop as a basal rosette of highly lobed leaves. Basal leaves are elliptic in outline, about 8 inches long by 2 inches wide, and occur on petioles. Stem leaves are alternate, lanceolate in outline, without petioles and with toothed margins. All leaves are covered with stiff hairs. Individual flowers are about 1/2 to 3/4 inch in diameter and consist of four light yellow petals. Plants have a large taproot with a distinctive radish odor and taste.
