What are the mixing quantities to make one gallon of spray with Remedy for basal treatment?

Response – For one gallon of basal bark spray with Remedy and Pentra-Bark, here’s the recipe:

One Gallon Mix:
0.8 oz Pentra-Bark (half the 4 oz bottle)
16 oz Remedy concentrate (1 pint)
48 oz water (3 pints)

Mixing steps:

  1. Add 24 oz water to your sprayer first
  2. Add 16 oz Remedy concentrate
  3. Add 0.8 oz Pentra-Bark
  4. Add remaining 24 oz water
  5. Agitate well for 2-3 minutes before spraying

Application:
Saturate the lower 12–18 inches of tree trunk using this basal bark method
Small trees (under 4″ diameter): 1–2 quarts per tree
Medium trees (4–8″ diameter): 2–4 quarts per tree

This ratio ensures Pentra-Bark works optimally to help Remedy penetrate the bark lenticels for better translocation into the tree’s vascular system.
