- Banol Turf and Ornamental Fungicide (also Banol Fungicide): Caution[1]
Yearly and per-crop limits
Turf can receive no more than 12.25 fl oz per 1,000 sq ft per year. Greenhouse crops are capped at 63 fl oz per 1,000 sq ft per production cycle and 2 applications, at least 7 days apart.[1]
Wear chemical-resistant gloves when planting into potting mix still wet from a Banol drench. It is not for use on sod farms in Arizona.[1]
Where it is used
Banol is a Pythium and Phytophthora product only. The label says it won't control brown patch, dollar spot or leaf spot, so pair it with a broad-spectrum fungicide if those are present.[1]
Use the lower turf rate with the shorter retreatment interval, and the higher rate with the longer interval. Severe pressure calls for the top rate and shortest interval.[1]
On ornamentals it goes on as a soil drench only, never as a foliar spray, and not on field-grown ornamentals. Trial it on unlisted species first.[1]
Don't apply it through irrigation systems or from the air. Stock solutions should be used within a day of mixing.[1]

Safety and environmental hazards
People
Signal word CAUTION: harmful if swallowed or absorbed through skin, and causes moderate eye irritation. Prolonged or repeated skin contact may cause allergic reactions, so handlers wear chemical-resistant gloves.[1]
Pets
The label has no pet-specific statement; its non-agricultural rule is to keep others out of treated areas until sprays have dried. Don't graze livestock on treated areas or feed them clippings.[1]
Bees and pollinators
The label has no bee or pollinator hazard statement.[1]
Fish and water
Don't apply directly to water or where surface water is present, and don't spray when weather favors drift.[1]
Resistance
Banol contains a Group 28 fungicide. To slow resistance, the label suggests tank mixes with equally effective fungicides from a different group and an integrated disease program.[1][2]
Common questions
- Does Banol control brown patch?

- How much Banol per 1,000 square feet of turf?
- 1⅓ to 2 fl oz preventive or 3 to 4 fl oz curative, mixed in 2 to 5 gallons of water.[1]
- When can people go back onto treated areas?
- On lawns, golf courses and other non-farm sites, once sprays have dried. In greenhouses and nurseries covered by worker protection rules, the restricted-entry interval is 12 hours.[1]
