Poor seedling vigor makes it slow to establish. Not strongly competitive until roots are established, so weed control is necessary if sown as a monoculture for hay or with fast growing species. Chemical Control: If an herbicide treatment is chosen, it is best to start treatments early in the fall. If grazing, wait three to five days to allow forage to dry and to avoid the possibility of bloat. AberLasting is able to maintain its leaf water content for far longer than conventional white clover, and has also shown excellent tolerance of cold temperatures and freezing and has great tolerance to clover root weevil. Once established, it will persist under heavy grazing pressure better than white clover. An official website of the United States government.

As with all pesticides, read, understand, and follow all label instructions and precautions. Ball clover is best suited to heavy soils, but is surprisingly well adapted to fairly dry sites as well. Maintain a minimum canopy height of 3-6 inches (8-15 cm). Once white clover has been eliminated in areas of the turf, bare spots will be left behind. Although Bigbee a higher percentage of hard seed and greater winter hardiness than some cultivars it suffers cold injury at 25 F (-4 C) and winterkills prior to the new, cold-tolerant cultivar Frosty. These more cold-tolerant cultivars are used in small grain>corn>soybean rotations in the Midwest, with good regrowth following oat companion crop harvest. For use as a green manure crop in mild climates, Multicut contributed an average of 280 lb N/acre (314 kg/ha) in a six-year trial in California with six cuttings per year. In the case of many annual clovers, much of the seed produced in spring or early summer will germinate in the autumn of that year, but some may lie dormant until subsequent years. Tolerates close grazing, but needs careful spring management to prevent overgrazing which will reduce seed production. Ladino varieties of white clover are usually most productive, but generally do not reseed well.Intermediate white clover types are better reseeders and more persistent, but usually are less productive. sharing sensitive information, make sure youre on a federal Trifoliolate leaves have finely toothed, smooth, hairless leaflets. Atrazine has a pre-and post-emergent effect on weeds, which means it helps to control both emerged weeds and weed seed.

Tilling can break up and spread weed seed and perennial weed rhizomes throughout the garden plot. Stipules are broad, gradually tapering to a point. Pubescent, prostrate runners (stems). Metsulfuron, such as in Quali-Pro MSM Turf Herbicide, gives very good control of white clover in bermudagrass, centipedegrass, St. Augustinegrass, and zoysiagrass lawns. It has a semi-erect growth habit similar to crimson clover, with somewhat later growth period in mid-spring. The most commonly used perennial clovers in the United States are white clover and red clover. Fine, trifoliolate leaves can have smooth or serrated edges, with varying shaped leaflets. Before Intermediate clovers have a medium leaf size and a leaf density that is very thick from the ground to the top of the plant and competes aggressively with weeds and grasses. Suited to USDA Plant Hardiness Zones 7b-9b. Low seedling vigor demands good weed control, thorough seedbed preparation, and good seed-soil contact for successful establishment. Seed no deeper than inch (1.25 cm). Thus, in addition to forage production situations, it is often used as a winter cover and/or green manure crop. Use pesticides only according to the directions on the label. Atrazine can be applied to St. Augustinegrass and centipedegrass up to two times a year. White clover is in the legume family (Fabaceae) and is capable of fixing its nitrogen, which enables it to thrive in unfertilized areas. Seed no deeper than inch (1.25 cm) at 2-3 lb/a (2-4 kg/ha) if drilled, double the rate if broadcast. Tolerates saline conditions better than red clover or alfalfa. 109 Crop Science Building Used to extend spring grazing in warm-season perennial grass pasture systems.
