Crossbow Herbicide Mixing Calculator: By Gallon or By Acre

Why Crossbow combines two actives

2,4-D and triclopyr are both broadleaf-selective growth-regulator herbicides — they twist and overgrow broadleaf plants to death while established grass mostly shrugs them off. Used alone, each has a gap: 2,4-D is strong on annual and perennial broadleaf weeds but weaker on woody stems and brush; triclopyr is the stronger woody-brush and basal-bark tool but costs more per gallon of active. Crossbow's 34.4% 2,4-D plus 16.5% triclopyr combination covers both gaps in one mix — annual broadleaf weeds, perennial broadleaf weeds, and woody brush and trees, without a tank mix.

That breadth is also why the label restricts where it can go. Crossbow is labeled for rangeland, permanent grass pastures, Conservation Reserve Program acres, fence rows, non-irrigation ditch banks, roadsides, and other non-crop and industrial sites — not residential lawns. Established grass tolerates it well enough for pasture use, but the label simply doesn't extend to turf. Target species commonly listed include poison oak, poison ivy, sumac, blackberries, kudzu, bindweed, leafy spurge, Canada thistle, milkweed, chicory, dandelion, clover, and thistle, among others — check the current label for the complete list before treating an unfamiliar species.

Crossbow vs. straight 2,4-D vs. Remedy Ultra

All three share a family resemblance but solve different jobs, and picking the wrong one is the most common mistake with this product family:

• Lawn broadleaf weeds (dandelion, clover, plantain in turf) — use straight 2,4-D amine. It's labeled for lawns; Crossbow is not.
• Basal bark treatment (painting concentrate on the lower trunk of a woody plant, typically mixed with oil rather than water) — use Remedy Ultra. Its higher triclopyr concentration (44.4%) is the standard choice for basal bark work; Crossbow's lower triclopyr percentage and water-based mixing aren't built for that method.
• Pasture brush and mixed broadleaf weeds, foliar spray — Crossbow is the right tool here specifically because it's pre-combined: one tank instead of mixing 2,4-D and a triclopyr product separately to hit both weed types in a single pass.

Against generic equivalents: several other brands (sold under names including Candor and Crossroads) use the identical 2,4-D and triclopyr percentages under the same label, generally at a lower price per gallon than the Crossbow name brand — worth comparing before buying if cost matters more than the label on the jug.
