Ecomazapyr 2 SL Herbicide (formerly known as Imazapyr 2 SL Herbicide), manufactured by Alligare, is a non-selective herbicide used to control hard-to-eliminate vegetation such as water hyacinth on water and weeds like crabgrass on land. While it holds many of the same properties as its previous label, its new improved condition includes the use within aquatic sites.

When sprayed directly on the plant, it will absorb into the leaves through the stem and to the roots, causing the plant to die within several days. While exceptional on its own, this emulsifiable concentrate can be mixed with a surfactant for a stronger residual for up to 120 days.

Ecomazapyr 2 SL Herbicide can be applied with various application methods, so that areas large or small can be rapidly cleared of unsightly plant growth on land and water or for a complete bare ground treatment.

Tools Needed

To apply Ecomazapyr 2 SL Herbicide, a stainless steel, fiberglass, plastic or plastic lined handheld sprayer or skid sprayer is needed.

When applied post-emergent to weeds, Ecomazapyr 2 SL Herbicide may require a surfactant.

How to Use

• Step 1: Determine how much Ecomazapyr 2 SL 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. = acre). For directed or spot spray applications, use 0.6 fl. oz. (0.5% concentration) to 6.5 fl. oz. (5% concentration) per 1 gallon of water. Spot applications in grass pasture and rangelands will use 2 to 48 fl. oz. of product per acre. Spot applications to grass pasture and rangeland may not exceed more than one tenth of the area to be grazed or cut for hay. For aquatic uses, apply this product at 1 to 6 pints per acre depending on species present and weed density. Do not apply more than 48 fluid ounces per acre per year or 6 pints of product per acre depending on the application site.
• Step 2: Fill the spray tank halfway with required amount of water and add the correct amount of Ecomazapyr 2 SL Herbicide. Pour the remaining half of water into the spray tank and shake until solution is completely mixed. If needed, add the surfactant last and shake again until it is fully mixed in with the solution.
• Step 3: Apply the mixed Ecomazapyr 2 SL Herbicide solution to unwanted weeds and plants until it is moist, but do not spray to the point of runoff. For brush up to 4 feet tall, spray downward to cover approximately 70% of the plant foliage and the crown. For brush 4 to 8 feet tall, apply a directed spray in a smooth vertical motion from the crown upward on at least two sides of the target vegetation, making sure to cover the crown whenever possible. For brush over 8 feet tall, apply a directed spray in a smooth zig-zag motion from the crown upward on at least two sides of the target brush. Do not apply near wanted vegetation as it can still soak up into the roots system and cause damage.

Where to Use

Ecomazapyr 2 SL Herbicide can be used on undesirable vegetation in grass pasture, rangeland and for establishment and maintenance of wildlife openings (except in the state of California). For control of undesirable vegetation in unimproved industrial non-cropland Bermudagrass and Bahiagrass, and industrial non-cropland areas such as railroad, utility, pipeline and highway rights-of-way, utility plant sites, petroleum tank farms, pumping installations, transmission lines, fence rows, storage areas, around commercial and industrial building perimeters, non-irrigation ditchbanks, access roads, airfields, airports, industrial bare ground areas, and under paved surfaces.

It may also be used on emergent and floating aquatic vegetation in and around standing and flowing water, including estuarine and marine sites. As well as vegetation growing in or around surface water in wetland, riparian and terrestrial habitats and can be used for cut stump, cut stem and frill and girdle treatments within aquatic sites.

Do not use this product on lawns, walks, driveways, tennis courts or similar areas where roots of desirable vegetation may extend and be exposed to potential injury and/or mortality from root uptake of Ecomazapyr 2 SL Herbicide. Nor on Christmas trees and food crops.

When to Use

Ecomazapyr 2 SL Herbicide can be used when unwanted post-emergent vegetation is evident. For pre-emergent applications make them when before or after mowing. If applied prior to mowing, allow at least three days of active growth before mowing. If following a mowing, allow sufficient time for the grasses to recover before applying Ecomazapyr 2 SL or injury may be amplified.

Performance of the product may be reduced if rainfall occurs within 2 hours of application.

Safety Information

Ecomazapyr 2 SL Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing or applying Ecomazapyr 2 SL Herbicide.

There are no grazing restrictions following application of this product. DO NOT cut forage grass for hay for seven days after application of this product.

Do not enter or allow others to enter treated areas until sprays have dried or until 48 hours have passed after application.

Special Considerations

Do not use Ecomazapyr 2 SL Herbicide near non-targeted plants. Do not mix, store or spray this product using unlined steel containers or spray tanks, with the exception of stainless steel.

When applied to desirable turf, Ecomazapyr 2 SL may result in temporary turf damage, death, and/or discoloration. Effects to the desirable turf may vary with environmental conditions.
