Growth Regulators
Florel® brand Growth Regulator
Florel® brand Growth Regulator is registered to reduce or eliminate undesirable fruit development on many ornamental trees and shrubs such as: apple, buckeye, carob, cottonwood, crabapple, elm, flowering pear, horse chestnut, maple, oak, olive, pine, sour orange, sweet gum (liquidambar) 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. Temperatures at the time of application should be between 65 degrees Fahrenheit and 95 degrees Fahrenheit for the best results. Do not apply to trees that are under stress from disease, high temperatures, drought, etc.
In university tests, we have received 95-100 percent control of undesirable fruit on many species. However, timing is extremely critical!
Florel® brand Growth Regulator is the only product registered in the U.S. to control mistletoe. It can be used on ornamental deciduous trees to control leafy mistletoe and on conifers for dwarf mistletoe control. On deciduous trees, the ideal time to apply is in the spring just before leaf-out. Daytime temperatures must be above 65 degrees Fahrenheit for good results. Spray only the individual bunches of mistletoe, not the entire tree. Complete kill will not be achieved, but it should be about four years before you will have to retreat. On conifers for dwarf mistletoe, apply in early summer prior to seed dispersal.
Florel® brand Growth Regulator is available in pint, quart, gallon and 2½ gallon containers. Ask for Florel® brand Growth Regulator at your local nursery or garden supply store or purchase this product online below.
