Imisol® is designed for trees experiencing both insect and disease pressure, including situations where insects vector disease pathogens such as Dutch elm disease. This dual-action formulation helps reduce application time while delivering systemic protection against a wide range of pests and pathogens.

Key Benefits

• Fungicide + insecticide in one treatment
• Broad-spectrum insect and disease control
• Systemic activity
• Minimal exposure risk application method

Available Sizes

Capsules

• 4 mL
• 6 mL
• 24 Pack or Case of 288

Capsule Size Guide

• 4 mL capsules – 2 to 10 inches DBH
• 6 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.
