Application Notes

For turf, apply with properly calibrated handheld, mechanical, or motorized spray equipment using sufficient water for thorough coverage. Suggested spray volume is approximately 2 to 4 gallons per 1,000 sq ft. For root pathogens, lightly irrigate with approximately 0.1 to 0.2 inch of water to move the fungicide into the active root zone. The minimum turf retreatment interval is generally 14 days.

For ornamental foliar applications, rates generally range from 8 to 24 fl oz per 100 gallons depending on the target disease. Soil drenches generally use 8 to 16 fl oz per 100 gallons and may be repeated every 21 to 28 days. Plant or cutting dips use 16 to 24 fl oz per 100 gallons for 10 to 15 minutes, while bulbs, corms, and rhizomes may be soaked for 15 to 30 minutes. Ornamental chemigation is permitted through labeled pressurized drench, sprinkler, and drip systems. Do not use thiabendazole or other thiophanate-methyl products as rotational partners because of similar chemistry and resistance concerns.
