Daconil Action is new to the turf market. What are the components of Daconil Action and why formulate a product in this fashion?
Agnew: The two components of Daconil Action fungicide are chlorothalonil and acibenzolar. Chlorothalonil is a familiar active ingredient to most superintendents and is a multi-site, contact fungicide. Acibenzolar, by itself, is highly active in stimulating a turfgrass plant’s defense system in a process called Systemic Acquired Resistance (SAR). Acibenzolar has no direct activity on a fungal pathogen. Chlorothalonil provides surface protection of the plant and acibenzolar stimulates the plant to protect itself internally. The combination provides improved disease control above each component individually and is an effective tool in a disease resistance management program.
What are the diseases that Daconil Action is most effective in controlling?
Agnew: Daconil Action provides enhanced control of dollar spot and anthracnose over Daconil WeatherStik. It also suppresses bacterial diseases such as bacterial etiolation (Acidovorax avenae subsp. avenae) and reduces pythium blight caused by Pythium aphanidermatum.
