VECTROL® is a foliar and soil applied potassium / plant-oil blend with ACT®. 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). Use it to balance your turf or plant insect and disease management program.


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. This results in faster recovery from environmental stresses caused by disease and insect infestation.


  • 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


Soluble Potash (K20)………………………………..10.0%

Derived From Fresh Water Algae and Potassium Hydroxide.

VECTROL® contains Biofeed’s exclusive Amino-Cell Technology® (ACT).



Vectrol® is highly concentrated for pro-level performance and value. 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.


ACT® | L-Form Amino Acids, Carbon, Hydrogen, Oxygen and Nitrogen that are key building blocks in all plant life. Contains freshwater algae.

ANTIOXIDANT | An additive known to attach to – and shut down – free radicles.

PHENOLIC ACIDS | The main polyphenols made by plants. These compounds have diverse functions and are immensely important in plant-microbe interactions/symbiosis.

POTASSIUM | Directs nitrogen use and water use in plants.

SAR | Enhanced Systemic Acquired Resistance (SAR) in plants improves their resistance to insects and disease.
