  • Applications

    Forchlorfenuron (CAS 68157-60-8) is primarily used as a plant growth regulator in agriculture, acting as a cytokinin-like compound to promote fruit set, increase fruit size, and improve marketable yield on crops such as grapes, kiwifruit, and cucurbits. It is typically formulated into agrochemical products (for example, foliar sprays and emulsifiable concentrates) and applied to crops after fruit set to regulate development. In horticultural research and practice, it serves as a tool to study cytokinin effects on fruit development and to optimize fruit quality and uniformity. Use is subject to local regulations and label directions, and it is treated as an active ingredient within regulated crop-protection programs rather than a general-purpose additive.
