ArborFos - Injectable Phosphite Fungicide Capsules

ArborFos Update: ArborFos has been approved under an EPA Section 2(ee) recommendation for the management of Beech Leaf Disease (BLD). This expanded use provides arborists with an additional tool for helping protect beech trees affected by this emerging disease. ArborFos can be applied as a trunk injection using standard tree injection equipment, allowing the active ingredient to move systemically throughout the tree while minimizing off-target exposure. Contact TIPCO for more information on incorporating ArborFos into your Beech Leaf Disease management program.

Capsule Label

Arborfos is a phosphite formulated fungicide that inhibits fungal growth through stimulation of the plant’s own natural defense systems. Research indicates that Arborfos may also elicit a type of systemic acquired resistance response. Although it imparts no actual phosphorous nutrition, Arborfos treated trees tend to develop healthier leaves, roots and stems as it reduces disease pressure. Arborfos is registered for ornamental, forest and certain crop trees to manage many diseases including root diseases.

• 10 mL Capsules – 10 inches DBH and above

Capsule Spacing

Install 1 capsule every 4–6 inches around the trunk circumference.

Quick estimate:
Capsules Needed ≈ DBH ÷ 2

Example: A 20-inch DBH tree typically requires approximately 10 capsules.

Note: Capsule dosages, also known as micro-injectors, are calculated by measuring the tree diameter at breast height, or DBH, in inches, then dividing that number by two to determine the total number of capsules.
