Branching Young Trees
| Timing | Product | Concentration | Rate | Comments |
|---|---|---|---|---|
| BEFORE buds break in spring on 1-year old wood | Maxcel, Promalin; exilis plus, exilis 9.5 SC | 5,000 ppm | see label | If dormant buds are present on one-year-old wood only. DO NOT apply after bud break. See product labels for more details and instructions. |
| AFTER bud break in spring on 1-year old wood | Maxcel, Promalin; exilis plus, exilis 9.5 SC | 400 to 500 ppm | see label | If buds have broken, and the leaf tissue is showing on one-year-old wood. Apply by spraying with a back-pack sprayer. Works best when temperatures are warm and there is enough tissue to absorb the PGR. Note: Never add surfactant to a solution of MaxCel as it is already included in the formulated product. Promalin should be combined with a NIS following the label instructions. |
| 2-year old wood, coinciding with bud break | Maxcel | 1,500 ppm | 9.2 fl oz per gal water | Make a notch with a hacksaw blade (narrow, fine-toothed saw, usually used for cutting metal) just above the existing bud scar on the leader. Then, on nonbearing trees, immediately spray the cut with a 1500 PPM solution. |
