  • Applications

    Flurprimidol is a plant growth regulator that inhibits gibberellin biosynthesis and is used in agriculture and horticulture to control plant height and improve crop uniformity. It is commonly applied in ornamental horticulture and container-grown nurseries to produce compact, stocky plants; used on fruit trees and vineyards to manage canopy size and improve fruit quality; evaluated for use in field crops to reduce lodging and optimize harvest index; and formulated as an active ingredient in crop-growth regulator products, subject to local regulations.
