Frequently Asked Questions
What is Maleic hydrazide?
Maleic hydrazide is a chemical compound with the molecular formula C4H4N2O2. It is derived from maleic acid and hydrazine and is commonly used as a plant growth regulator and herbicide. Maleic hydrazide is a white crystalline solid that is soluble in water and organic solvents.
Maleic hydrazide is primarily used in agriculture to control the growth of various plants. It works by inhibiting cell division and growth, which leads to the suppression of sprouting and the control of vegetative growth. It is often applied to crops and stored produce to prevent sprouting during storage and transportation. By inhibiting sprouting, it helps extend the shelf life of fruits, vegetables, and tubers.
Additionally, maleic hydrazide has applications in horticulture, where it is used to control the growth of unwanted plants in ornamental and noncrop areas. It can be applied as a foliar spray or as a soil drench to inhibit the growth of weeds and unwanted vegetation.
