Monterey Florel® Plant Growth Regulator is a professional-grade foliar spray designed to manage plant growth, eliminate nuisance fruit, control mistletoe, and promote healthier ornamental plant development. Formulated with Ethephon [(2-chloroethyl) phosphonic acid] 3.9%, Florel works by releasing ethylene, a naturally occurring plant hormone that regulates growth, flowering, fruit development, and aging processes in plants.
Widely used by landscapers, horticultural professionals, nurseries, and advanced gardeners, Monterey Florel® helps reduce messy fruit drop on ornamental trees, stimulate fuller branching, manage plant size, and encourage flowering in select ornamental species. It is also highly effective for controlling both leafy and dwarf mistletoe on deciduous trees and conifers.

How Monterey Florel® Works
After application, Ethephon is absorbed into plant tissue where it breaks down into ethylene gas, a naturally occurring plant hormone responsible for regulating growth, ripening, flowering, and plant aging processes.
Important Application Information
- Timing is critical for successful fruit elimination applications
- Apply during the mid-to-full bloom stage before fruit set occurs
- Do not apply to drought-stressed, heat-stressed, or diseased plants
- Plant stress may increase the risk of leaf scorch, defoliation, or flower drop
- Thorough foliar coverage is essential for best results
Always read and follow all label directions before use. Review the official Monterey Florel® product label for complete application rates, plant-specific instructions, and state registration information.
