  • Applications

    Mepiquat (CAS 15302-91-7) is primarily used as a plant growth regulator in agriculture to inhibit internode elongation and reduce excessive vegetative growth, helping to manage plant height, improve boll set and harvest index in cotton. It is commonly formulated as a foliar spray for field applications at label-directed rates. Beyond cotton, the active has been evaluated or used in other crops such as rice and certain cereals, and in some cases for canopy management in vegetables under specific regulatory approvals. Its use is typically part of crop-management programs to optimize yield stability, with applications and rates governed by local regulations and formulation limits.
