Frequently Asked Questions
What is Florel Brand Pistill?
Florel is a contact growth regulator based on the chemical ethephon. It is registered for use in agriculture as a ripening agent. Florel is registered to control nuisance fruit in commercial ornamental trees & shrubs such as: apple, buckeye crab-apple, carob, cottonwood, elm, flowering pear, horsechestnut, liquidamber (sweet gum) maple, oak, olive, pine, sour orange & sycamore trees.
How does it work?
Florel breaks down into ethylene, a naturally occurring compound, in the plant. When a plant is under stress it produces ethylene. If the plant is in bloom at the time of excess ethylene production, the first symptom is blossom abortion. This is how Florel works; it causes the plant to abort it’s blossoms.
Can I spray after fruit has set?
No. Florel needs to be applied when the tree is in mid to full bloom for effective fruit elimination.
How much water do I use on each tree?
The tree needs to be sprayed to wet. Excessive runoff is a waste of material. The average size tree will require 5-20 gallons of spray for treatment.
Does Florel Brand Pistill have any color?
Florel is an odorless, clear liquid.
Is it necessary to cover the lawn or shrubs growing under the tree?
No. If concerned about drift, simply rinse off plants with water.
Should I use a surfactant?
On evergreen trees (olives, citrus, etc.) a surfactant is not recommended. On deciduous trees, a surfactant may be used.
Does Florel kill bees?
Florel has no insecticidal properties.
How do I mix Florel Brand Pistill?
Mix only enough solution to supply your morning spray needs. Once mixed with water, Florel will start to hydrolyze. Mix the amount you will need for afternoon spraying, just before use. If the pH of the spray solution rises about pH 5, it will be ineffective.
Are there adverse effects on the leaves when Florel Brand Pistill is used?
No. Florel works on contact only; it does not enter the tree like other growth regulators. Consequently, it will not have adverse growth effects, and there is no burn (phytotoxicity) to the new leaf growth.
