Banish by Supreme Growers

This oustanding fungicide uses the power of Geraniol, a natural geranium oil plant extract, to control common mildews in plants. BANISH works in a two-fold process to prevent mildew growth and heal plants from the cell up. Mildews first appear as spores at the plant surface; from there they send out tubes that grow and feed off the host plant's nutrients. The Geraniol in BANISH works by creating an unbalance of potassium (K+) ions in the mycelium. This unbalance inhibits spore germination and mycelium growth and will, ultimately, enter the pathogen cell and kill it. The result is a healthier, pathogen-free plant.

BANISH is effective against the following plant diseases:

  • Podosphaera fusca, the powdery mildew found on cucumbers, melons (including watermelons) and squashes (including pumpkins).
  • Erysiphe nector (Uncinula necator), the powdery mildew endemic to grapes.
  • Podospheara leucotricha, the powdery mildew that affects both apples and pears.
  • Podospheara aphanis, the powdery mildew commonly found on blackberries, raspberries and roses.
  • Oidium lycopersicum, the powdery mildew to which tomatoes are susceptible.

BANISH is thoughtfully manufactured to provide superior results. The oils are naturally sourced and carefully harvested then cold-pressed for extraction to preserve their purity; no heat or chemical solvents are used. This pure oil is then micronized and amplified in a patented process that offers superior spreadability over the treated area, deeper penetration into pathogens and faster absorption for quick control.


Suggested Uses: For use on all types of plants as a foliar spray to control powdery and downy mildews.
