| Description | Maleic hydrazide (MH) was introduced into agriculture in the 1950s as a major commercial herbicide and a depressant of plant growth. It is a plant growth regulator (sprout inhibitor) and herbicide, that acts by inhibiting cell division in plants. It is used to control sprouting of potatoes and onions, suckers in tobacco, and growth of weeds, grasses and trees in/along lawns, turf, ornamental plants, non-bearing citrus, utility and highway rights-of-way, airports and industrial land. Most of the maleic hydrazide used in the U.S. is applied to tobacco (86-88%), followed by potatoes (10%), It is used to control sucker growth on tobacco plants, retardation of flowering and prolongation of dormancy period. |
