Bayer Prograss EC Herbicide

Bayer Prograss EC Herbicide is your year-round solution for Poa annua and a spectrum of common annual grasses in cool-season turf and overseeded bermudagrass. This ethofumesate-based emulsifiable concentrate delivers both pre- and post-emergent control, meaning you can target Poa annua from germination through active growth across all seasons. With a flexible Prograss program, you can tailor treatments to your specific turf type and climate, keeping lawns, golf greens, sod farms, and other turf surfaces cleaner and healthier year after year.

What makes Prograss EC stand out

• Two-pronged weed control – active before and after Poa annua germinates, plus suppression of a broad array of annual grasses and certain broadleaf weeds.
• Season-spanning effectiveness – designed to work across cool and warm periods, making it suitable for continuous Poa management in every season.
• Broad turf compatibility – recommended for bentgrass, tall fescue, St. Augustinegrass, Kentucky bluegrass, and perennial ryegrass, with specific notes for bermudagrass management in St. Augustinegrass systems.
• Climate versatility – effective in both humid and arid climates, giving turf managers flexibility no matter where you play or live.
• Real-world uses – approved for golf course fairways, sod farms, cemeteries, and both commercial and residential lawns, making it a versatile choice for professionals and homeowners alike.

What it controls and where to apply

• Poa annua (annual bluegrass) and a range of annual grasses including crabgrass, barnyardgrass, large and smooth crabgrass, green foxtail, yellow foxtail, and canary grass.
• Selected broadleaf weeds such as white clover and common chickweed, offering broader weed suppression in a single program.
• Suitable for overseeded bermudagrass and established cool-season grasses in greens, fairways, tees, and residential lawns.

How to use

Rate of use is 1.5 to 6 fluid ounces per 1,000 square feet, depending on turf type and labeling. For best results, follow the label directions on timing, tank-mixing restrictions, and required intervals between applications. Calibrate your sprayer to deliver uniform coverage and avoid runoff. Consider integrating Prograss EC into a broader turf management plan that includes proper fertilization, mowing height, and irrigation practices to maximize weed suppression while protecting desirable grasses.

Usage scenarios and ideal targets

• Golf course professionals managing Poa annua pressure on fairways and overseeded areas during transition periods.
• Sod producers seeking reliable control of annual grasses to protect stand establishment and turf density.
• Municipal and commercial grounds managers aiming for consistent weed control across lawns, medians, and park spaces.
• Homeowners with mixed turf lawns featuring bermudagrass overseeding or cool-season grasses, needing a single product to manage Poa annua across seasons.

Practical tips for best results

• Use Prograss EC as part of a coordinated Poa annua management plan rather than as a one-off solution—consistent applications aligned with Poa germination windows yield the strongest suppression.
• Match rate to turf type and growth stage; younger, actively growing turf types may respond differently than established stands. Always follow the label for rates and re-entry restrictions.
• Monitor irrigation and rainfall after application; excessive irrigation soon after treatment can influence absorption, while targeted irrigation helps avoid stress on desirable grasses.
• Combine with cultural practices such as adjusting mowing height and improving soil health to support dense turf that naturally resists Poa annua encroachment.
