4-CPA CAS:122-88-3

4-Chlorophenoxyacetic acid (4-CPA) serves multiple agricultural purposes, primarily as a growth regulator for various horticultural and ornamental crops. When applied at specific growth stages, 4-CPA promotes desirable plant responses, including increased fruit set, control of vegetative growth, and the induction of flowering. In orchard management, 4-CPA is utilized for fruit thinning to regulate crop load, improve fruit size and quality, and minimize biennial bearing tendencies in perennial fruit trees. Moreover, 4-CPA is employed in the production of seedless fruits, where it aids in the development of parthenocarpic fruits without the need for pollination, contributing to enhanced yield and marketable fruit production. Additionally, its application in nursery operations supports the production of compact, well-branched young plants with improved transplant success and uniform growth characteristics. In certain cropping systems, 4-CPA is used to control weed growth and manage unwanted vegetation, as its selective herbicidal properties target broadleaf weeds while preserving the growth of desired crops. Its role in weed management contributes to efficient crop establishment and maintenance, particularly in specialty crops and ornamental plant production. Overall, 4-Chlorophenoxyacetic acid plays a vital role in modern agriculture, offering targeted control over plant growth and development while supporting efficient crop production, fruit quality enhancement, and weed management across diverse horticultural and ornamental cultivation systems.
