View the Labels/SDS information for Daconil Action Fungicide.
Daconil® Action™ fungicide is a multi-site contact fungicide containing the most utilized active ingredient in turf: chlorothalonil, plus a "Turf Protein Booster" enhancing active ingredient Acibenzolar-S-methyl. Unlike traditional methods of disease control, this active ingredient is not a fungicide as it has no direct effect against pathogenic fungi and bacteria. Instead, it acts much like a vaccination. When applied, Acibenzolar-S-methyl triggers the natural defense response, or the Systemic Acquired Resistance (SAR), of the turfgrass by activating production of pathogenesis-related proteins (PR proteins). The PR protein boost awakens the turf's resistance to biotic and abiotic stresses like drought. In addition, this internal response within the plant enhances its own defense system against certain fungal and bacterial disease attacks. Thus, Acibenzolar-S-methyl bridges the gap between genetic resistance and conventional disease control by activating the plant's own natural defenses.
A FIFRA Section 2(ee) recommendation for a Daconil Action use rate of 1.6 - 2.0 fl. oz. per 1,000 sq. ft.* allows for another 24 to 28 days of dollar spot control on fairways. That's 33 percent more than generic products. With this new lower application rate, you get an extra month of peace-of-mind regarding what's beneath your feet.

The development of gray leaf spot in the transition and northern climates has changed the management of perennial ryegrass forever. Perennial ryegrass was first adopted by turfgrass managers because of the better tolerance to fairway and tee mowing heights versus Kentucky bluegrass. Read more »
Over time, bermudagrass decline and take-all root rot have been mistaken for each other in the turf industry. Bermudagrass decline and take-all root rot have distinct issues that need to be managed differently, especially on ultradwarf bermudagrasses. Read more »

Extreme weather conditions, whether too hot, too cold, too dry, or too wet, can impose a great deal of stress on turf grasses. Read more »
"Last year, even in a severe weather system, we actually were able to manage the fairways so they were soft but not soft to a point where they lost their playability. Golf course playability was dramatically improved with Daconil Action."
Highland Golf and Country Club, Indianapolis, IN
"When it was 106°F I sprayed Daconil Action—the turf didn’t wilt, the plants were healthy. I had peace of mind that my greens were covered during summer stress times. I went to the lake, enjoyed my family and didn’t worry about it."
Glendarin Hills Golf Club, Angola, IN
“I’m able to push things farther and do more practices like double cutting and rolling with Daconil Action. It’s helped and I’m able to push the greens."

"I like the dual action of Daconil Action. The chlorothalonil addressed dollar spot, which is a disease that we constantly battle in the summer; and the acibenzolar enhanced turf quality, which meant a healthy, dense stand of turf with good color."
Youngstown Country Club, Youngstown, OH
"We usually get a huge dollar spot outbreak in early fall. But the incidence of dollar spot on fairways that had been treated earlier with Daconil Action was 60% to 70% less than the non-treated fairways. Disease control was excellent."
Fairlawn Country Club, Akron, OH
"On the fairways where we used Daconil Action, we saw a healthier stand of grass than on the adjacent fairways that were under our normal spray program. Daconil Action provided heat and stress tolerance that other products didn’t. The turf had better color and showed less stress."
Sweetbriar Golf & Pro Shop, Avon Lake, OH
"The protein boost of Daconil Action didn’t mean anything to me until I tried it. I definitely saw results. It improved the turf color right away. It’s a unique benefit."
Rich Valley Golf, Mechanicsburg, PA
"I'm very, very satisfied with the use of Daconil Action since I've been using it. I would call it one of my go-to products—one of the products I would keep on the shelf and use throughout the year, not just one particular time of year. The protein boost allows you to keep the rates low and improve the health of the turfgrass at the same time."
