Use 1/8 to 1/2 fluid ounce per 1,000 square feet in 2 gallons of water for Monterey Thistledown, depending on the weed you’re targeting. That works out to about 1/16 to 1/4 fl oz per gallon if you’re scaling the labeled mix rate down evenly.

Quick Scoop

  • For a light/spot treatment , start near the lower end of the label range.
  • For tougher thistle or dense growth, the label range goes up to the higher end.
  • The product is meant for use when weeds are young and actively growing.
  • Always follow the product label for the exact weed and application site.

Simple Per-Gallon Math

The label rate given in the sources is per 1,000 sq ft in 2 gallons of water.

So, per 1 gallon of water , that equals:

  • 1/16 fl oz per gallon at the low end.
  • 1/4 fl oz per gallon at the high end.

Practical Note

If you’re spraying a small area, it’s better to mix based on the area you’re treating , not just fill a gallon and guess. That helps avoid under- or over-applying the herbicide.

TL;DR

Mix 1/16 to 1/4 fl oz per gallon of water as the rough gallon-scale equivalent of the labeled Monterey Thistledown rate.
