General Information


Domark fungicide is formulated as a 1.9 pound active ingredient per gallon micro emulsion (ME). The active ingredient in Domark is tetraconazole, a triazole fungicide that works by inhibiting demethylation and other processes in sterol biosynthesis. Tetraconazole is absorbed quickly into the plant tissue and like all triazoles can move up, but not down the plant. Optimal disease control is achieved when Domark is applied in a regularly scheduled spray program. When using Domark in combination and/or rotation with other fungicides, it is important to use fungicides that have different modes of action (i.e. non Group 3 fungicides). Since Domark is a sterol-biosynthesis inhibiting fungicide, avoid rotating with other sterol-biosynthesis inhibitors, such as Folicur, Tilt, or Laredo.


To avoid drift, apply the largest droplet size possible that will provide uniform coverage and result in satisfactory disease control.

Limitations, Restrictions, and Exceptions


1. Do not apply Domark after soybean growth stage R5 (beginning seed).

2. Do not graze or feed soybean forage or hay to livestock.

3. Chemigation: Do not apply Domark through any type of irrigation system.

4. Do not harvest immature soybeans for consumption once plants are treated with Domark.

5. Do not use on vegetable soybean varieties grown for their immature pods.


When to Apply: If necessary repeat with a second application before growth stage R-6. Curative applications are most effective when disease incidence does not exceed 5% of the soybean plants at time of application.

Special Use Instructions: Use Domark as part of an integrated pest management program (IPM). Apply as a foliar spray in sufficient water to obtain thorough coverage of soybeans.

LOUISIANA: For replanting sugarcane 45 days after the last application to soybeans.
