Bonide Poison Ivy & Brush Killer BK-32, 32 oz Concentrate

Bonide Poison Ivy & Brush Killer BK-32 is a 32-ounce concentrated liquid designed to tackle aggressive woody growth, vines, and broadleaf yard weeds. It provides a targeted solution for homeowners managing stubborn overgrowth like poison ivy, poison oak, kudzu, wild blackberries, and thistle without having to dig up roots manually.

The concentrate is formulated to eliminate over 240 weed types and diseases, working down into the roots while remaining safe for residential lawn grasses when used as directed. It is compatible with major turf species including Bluegrass, Fescues, Rye, Bent, Bermuda, Bahia, and Zoysia. Application is straightforward, as the liquid mixes instantly with water for use in either a tank sprayer or a hose-end sprayer.

In addition to standard foliage spraying, this formula doubles as a stump killer. To prevent regrowth after cutting down unwanted trees, you can apply the undiluted concentrate directly onto the entire surface of a freshly cut stump using an ordinary paintbrush.

Keep in mind that this is a concentrate rather than a ready-to-use spray, so you will need to provide your own application gear like a sprayer or paintbrush and mix it with water according to the label. The product details also do not specify how many square feet or gallons of spray a 32-ounce bottle yields.

Verdict: Bonide BK-32 is an effective choice for homeowners dealing with persistent vines, broadleaf invaders, or leftover tree stumps across standard residential lawns. It offers great utility if you need a versatile concentrate that targets weeds down to the root without harming your grass.

A great fit if you:

• Need to eliminate tough vines like poison ivy, poison oak, or kudzu
• Want to treat lawn weeds in Bluegrass, Fescue, Rye, Bent, Bermuda, Bahia, or Zoysia turf
• Have freshly cut tree stumps you want to treat directly with undiluted killer
• Already own or plan to use a tank sprayer or hose-end sprayer

Consider something else if you:

• Prefer a ready-to-use spray bottle that requires no measuring or mixing
