Vectrol® is a foliar and soil applied potassium-based activator solution with ACT®. When applied as directed, this dynamic solution is quickly absorbed via cellular translocation where it improves the quantity and ratio of antioxidants and phenolic acids produced by plants.

Vectrol® goes further than standard fertilization as it stimulates and supports dynamic cellular function and growth while it reduces insect and disease occurrence via enhanced Systemic Acquired Resistance (SAR).

This results in faster recovery from environmental stresses caused by disease and insect infestation. Vectrol® complements the use of plant protection products. Use it to balance your turf, plant or crop insect and disease management program.


  • Enhances disease and insect resistance via enhanced SAR
  • Promotes drought and heat tolerance
  • Faster cell repair following mowing and wear
  • Blends well with most fertilizers and crop protection chemicals
  • Easily sprayed on or applied through fertigation systems
  • Increases crop harvest and bottom line

VECTROL® also contains Biofeed’s exclusive Amino-Carbon Technology® ACT to provide natural organic acids, surfactants, enzymes, amino acids, bio-stimulants, and buffers.



Vectrol® is highly concentrated. Dilute with water to ensure adequate coverage. Jar test for compatibility prior to final tank mixing with other products.

AGRICULTURAL CROPS, TREES AND SHRUBS: Foliar spray directly to the leaf surface at a rate of 2-4 Quarts in 3-50 gallons of water and spray to the point of runoff or as directed your Biofeed® products dealer. Frequency, rate, and quantity of applications depend upon specific plant and soil requirements.

GREENS, TEES AND TURF: As a foliar, apply 2-6 Quarts in 50-100 gallons of water per acre, or for smaller areas apply 8-32 ounces in 10-20 gallons of water per 1000 square feet, and spray to the point of runoff. Frequency and rate of applications may vary.
