Alligare Mainline Herbicide
10/22/26
Alligare Mainline Herbicide, manufactured by Alligare, is a specially formulated non-selective herbicide that offers total kill over a broad-spectrum of weeds.
Effective on problematic weeds like dogfennel and pigweeds in both their pre and post-emergent stages with its multiple active ingredients and two modes of action.
Alligare Mainline Herbicide offers quick burndown of weeds upon contact and offers flexible application rates for individual spot treatments or total bare ground control.

- Step 1: Determine how much Alligare Mainline Herbicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). For broadcast applications, use 16-24 fl. oz. of Alligare Mainline Herbicide in 10 gallons of water per acre. For spot treatments in bareground or total vegetation, use .55 fl. oz. of product with 0.25-0.5% v/v methylated seed oil (MSO) per 1,000 sq. ft. Do not apply more than 0.55 fl. oz. of product per 1,000 sq. ft. or apply more than 24 fl. oz. of product per acre per year per application. Do not make more than one application per year.
- Step 2: Fill the spray tank with half the amount of water, add the measured amount of Alligare Mainline Herbicide while agitating the tank. Pour in the remaining half of water and shake until the solution is mixed.
- Step 3: Spray Alligare Mainline Herbicide directly to the soil surface for pre-emergent weed control or to the top and bottom of desired weeds until wet, but not to the point of runoff. Avoid the spray from contacting desired plant species. Water with 1/2 inch of irrigation when 2-3 weeks have passed after the first application.
