Please refer to the product label for complete mixing and application instructions.
The best time for application of Monterey Florel Brand Growth Regulator on any flowering plant is the mid to full bloom stage.
Monterey Florel Brand Growth Regulator should not sprayed in a way that could contaminate water used for irrigation or domestic purposes.

If the tree is already under stress, Monterey Florel Brand Growth Regulator may increase the stress on the tree. It works on contact only, it does not enter the tree like other growth regulators. Therefore, it will not have adverse growth effects and there is no burn (phytotoxicity) to the new leaf growth. We would recommend speaking to the manufacturer, Monterey Lawn and Garden, for further assistance. Their phone number is 559-499-2100.

Per the product label: Applications of Monterey Florel Brand Growth Regulator should be made at the mid to full bloom stage, prior to fruit set in spray volumes sufficient to wet, but not to runoff. Failure to wet blooms thoroughly will cause incomplete fruit elimination. Spraying too much (until runoff) may cause some defoliation or other plant injury. Sprays applied too early or too late will be less effective and result in incomplete fruit elimination. The activity of Florel is linked to plant growth activity and is therefore slower-acting when temperatures are low (60ºF) or very high (95ºF). Trees or shrubs should not be under stress when treated such as from drought, insects or diseases. Apply when rain is not expected for 24 hours.
Per the product label: For most bromeliad varieties, mix 8 fluid ounces of FLOREL BRAND GROWTH REGULATOR per gallon of water. This prepares a spray concentration of approximately 2,500 ppm of ethephon. Spray all surfaces of the plant to “wet”. Avoid overspraying to “runoff” which may cause damage to leaves or the growing points. For treating groups of plants, use approximately 1/2 pint of spray solution per 10 square feet of greenhouse bench or outdoor bed area.

Monterey Florel Brand Growth Regulator must be applied before fruit set for best results, and this is usually done when the plant is in mid- to full- bloom. If there is always fruit on the trees, then you may need to prune them back and then apply as the tree is regrowing and before that fruit set.
