HEMP-NETTLE (Galeopsis tetrahit) OTHER NAMES: Dog nettle, bee nettle, flowering nettle, wild hemp, ironweed. ORIGIN: Eurasia HABITAT: Cultivated fields, open woods, and waste places. DESCRIPTION: Annual reproducing by seeds. STEMS: Covered with bristly hairs, 30-76 cm high, swollen at the nodes. LEAVES: Opposite, 5-10 cm long, coarsely toothed, hairy, long-stalked FLOWERS: Clustered in the axils of the upper leaves, petals united, white or pink suffused with purple. SEEDS: 2.3 mm long, egg-shaped, grayish-brown CULTURAL CONTROL PRACTICES: CROP COMPETITION - Hemp-nettle germinates better at high temperatures. Control of seedlings may be better with early seeded crops because the crop will be more competitive by the time hemp-nettle germinates. CULTIVATION - Early spring tillage may encourage germination. Shallow cultivation of summerfallow is recommended to keep seeds near the surface and to allow maximum germination. ROTATIONS - Periodic seeding down to grasses and legumes gives satisfactory control because forages are harvested before the hemp-nettle sets seed and any growing plants are destroyed by harvesting operations. CHEMICAL CONTROL PRACTICES: Chemical control measures to control this weed can be found in The Guide to Crop Protection. This publication is issued annually and is available from Rural Service Centres and the Sustainable Production Branch, Saskatchewan Agriculture and Food, Regina, Saskatchewan.
