Project at a Glance Contents on the CD ROM
  • Maleic Hydrazide is a compound belongs to the class of pyridazinediones, 6-membered aromatic rings containing two adjacent nitrogen atoms
    (pyridazine), doubly substituted with oxygen.
  • Maleic hydrozide is recommended for the temporary growth inhibition of various trees, shrubs and grasses .
  • Formulations include an emulsifiable concentrate and soluble  concentrate/ liquid and solid.
  • Maleic Hydrazide is used in horticulture and agriculture field as a weed killer and growth inhibitor (nonauxin plant regulator).
  • It is used as a chemical intermediate for the synthesis of other pyridazine and dione compounds.
  • Maleic hydrazide functions as a growth regulator acting especially on root vegetables.
  • Maleic hydrazide is applied as over-the-top foliar spray when the foliage is still in a good condition.
  • Maleic hydrazide is well known in agriculture as a growth inhibitor, but its mechanism of action is uncertain.
  • Maleic hydrazide, a polar compound, is highly soluble in methanol.
  • Maleic hydrazide has been available for potato sprout control for many years
  • 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.
  • Maleic hydrazide is of low acute toxicity.
  • Maleic hydrazide is mobile, especially in sandy soils, but not persistent in the environment.
  • In acute toxicity studies, maleic hydrazide is "practically nontoxic" to
    birds, fish, invertebrates and honey bees.
  • The use of currently registered pesticide products containing maleic
    hydrazide and the potassium salt of maleic hydrazide in accordance with approved labeling will not pose unreasonable risks or adverse effects to humans or the environment.
