FlorelⓇ brand Growth Regulator is registered to reduce or eliminate undesirable fruit development on many ornamental trees and shrubs such as: apple, buckeye, cottonwood, crabapple, elm, flowering pear, horse chestnut, maple, oak, pine, and sycamore. It also works on many other species that produce nuisance fruit.

Application must be made prior to fruit set; apply at the mid to full bloom stage in sufficient water to wet (do not spray to run off). Good spray coverage is essential for complete fruit elimination. Application made too early or too late will also not be effective. Apply at 1 quart per 10 gallons of water (3 oz./gallon). The amount of spray used will depend upon the size of the tree. Temperature at the time of application should be between 65°F and 95°F for the best results. Do not apply to trees that are under stress from disease, high temperatures, drought or other environmental stress conditions.

In university test, 95-100% control of undesirable fruit has been achieved. However timing is extremely critical.
