Full Description

Finalsan is a powerful contact herbicide for the total weed control of moss, algae and many common broad-leaved weeds on areas such as vineyards and orchard crops. Finalsan is a total weed killer that DOES NOT contain glyphosate, instead its active ingredient is 186.7g/l pelargonic acid. Rapid desiccation is caused by the active ingredient penetrating the waxy layers of the leaf cuticle and destroying the cell membranes of the plant’s epidermal cells.

Our Recommendation

  • Save money and time and mix in Blue Dye to ensure no areas are missed or overdosed.
  • Always wear protective clothing, such as Chemical Resistant Gloves, when handling Finalsan.
