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.
The Monterey Florel Growth Regulator and most other plant growth regulators on the market must be applied as a foliar spray to work. The chemicals need to be directly applied to the leaf tissue to work and will not be pulled through the root to impact the plant in the way you are hoping. It is not a systemic product and will not be pulled through the tree. You may need to hire a company that has a spray rig that can reach the top of the trees for you, or see if there is equipment you can rent to do a proper foliar spray treatment.
Monterey Florel Brand Growth Regulator is not labeled to control berries in pyracantha bushes. You can consider using Atrimmec Plant Growth Regulator on pyracantha.
Per the product label, any Monterey Florel Brand Growth Regulator spray solution should be used within 24 hours after mixing. DO NOT save unused diluted spray solutions as they will not be as effective as fresh solutions.
According to 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
Monterey Florel Brand Growth Regulator will reduce or eliminate undesirable fruit development on many ornamental trees and shrubs. Although mulberry trees are not specifically stated on the label, this product may work to stop your trees from bearing fruit. For further product questions, you may reach the manufacturer directly at (559)-499-2100 or [email protected].
Monterey Florel Brand Growth Regulator is not labeled to control pods in a locust tree. Some articles recommend the use of the active ingredient Ethephon for this application, but unfortunately, we do not have a product with it that is labeled for use as effective on honey locust. Most plant growth regulators used to prevent fruit set must be applied as a full coverage spray during the mid- to full-bloom stage.
Monterey Florel Brand Growth Regulator is not labeled to control cotton fuzz on silver poplar trees. We recommend that you consult with your local cooperative extension office for product recommendations as this month is when the heaviest amount occurs after pollination.
Monterey Florel Growth Regulator could potentially be used on flowering ficus, however this product should not be applied in any way that would allow for overspray or runoff into a pond with aquatic life. When using Florel over grassy or other non-aquatic areas, you need to apply at bloom - before fruit set - wetting the blooms but not spraying to the point of runoff. You would use 3 oz per gallon of water. If the trees are a constant problem over the pond, then the long-term solution may be removing or transplanting the trees to a different location.
