Hardball Herbicide

Hardball Herbicide, manufactured by Helena Chemicals, is a powerful, new-generation 2,4-D acid herbicide designed for selective, post-emergent control of tough broadleaf weeds and brush in turf, golf courses, aquatic areas, and more.

The power of this herbicide concentrate relies on 2,4-D, which causes uncontrolled growth in noxious plants and leads to stem curl-over, leaf withering, and eventual weed death within a couple of days. One of HardBall Herbicide's key advantages is its ability to provide excellent weed control even in cooler weather, extending treatment windows in spring and fall.

Hardball Herbicide performs well at lower rates than conventional 2,4-D products, offering cost savings and efficiency. Its low-odor, low-volatility, cool-weather performance, and built-in surfactant system make it a standout in areas where precision, discretion, and efficacy matter most.

Tools Needed

A handheld pump sprayer, backpack sprayer, helicopter, fixed-winged aircraft, or spray rig will be needed. 

Use power sprayers operated with a boom or spray gun mounted on a boat, tractor, or truck for aquatic treatments.

How to Use

• Step 1: Determine how much Hardball Herbicide to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiplying 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). Depending on the cool-seasoned turf, apply 0.56 to 1.28 oz. of Hardball Herbicide per 1 gallon of water per 1,000 sq. ft. For warm-seasoned turf, the rate will vary between 0.75 to 1.28 oz. of product per 1 gallon of water per 1,000 sq. ft. depending on the turf type. Refer to the product label for specific application rates and restrictions. 
• Step 2: Fill the spray tank halfway with clean water. Add HardBall at the recommended rate. Continue filling with the remaining half of the water and agitate the solution thoroughly.
• Step 3: Spray the top and bottom of weed leaves until wet, but not to the point of runoff. When spraying shoreline weeds, allow no more than 2-foot over-spray onto the water with an average of less than 1-foot over-spray to prevent the introduction of greater than negligible amounts of the chemical into the water. Do not water the turfgrass for 24 hours after application.

Where to Use

Hardball Herbicide can be used in cool season and warm season turfgrass established for commercial sod production. It may also be used for forest management, forest roadsides, established conifers (including Christmas trees), roadsides, medians, highway, railroad, utility and pipeline rights-of-way, vacant lots, around utility installations, transformers, pump houses, and buildings, storage areas, fences, guardrails, lumber yards, industrial sites, airports, tank farms, farmsteads, and non-crop areas.

Aquatic sites such as lakes, ponds, reservoirs, marshes, bayous, drainage ditches, canals, and rivers and streams that are quiescent or slow-moving can be treated.

When to Use

Best results are obtained when the product is applied to young succulent weeds and brush that are actively growing.

Do not apply immediately before rainfall or irrigation.

Safety Information

Hardball Herbicide is safe for people and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product. 

Keep people and pets out of the treated area until 48 hours have passed after application.

Special Considerations

This product may cause injury to desirable plants by contacting foliage, stems, or roots.

For selective postemergent weed control, do not add oil, surfactant, fertilizer, or other additives.
