Compass 50 WG Fungicide, manufactured by Bayer, is a versatile fungicide that can be used as either a water dispensable granule or water soluble packet to deliver complete preventative and curative control against residential and commercial turf and ornamental diseases.
Powered by the active ingredient trifloxystrobin 50.0%, this product forms weather-resistant deposits in the waxy layer of the plant to provide long-lasting disease control despite several climate conditions.
Compass 50 WG Fungicide delivers longer residual protection from foliar, stem, and root diseases than other contact products on the market.
Tools Needed
To use Compass 50 WG Fungicide, you will need use either a handheld pump sprayer, backpack sprayer, or spray rig. To use this product in its water soluble packets, you may need to use a measuring spoon (not intended for feeding or reuse purposes).
Do not apply this product through any type of irrigation system or aerial application equipment.
How to Use
- Step 1: Determine how much Compass 50 WG Fungicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). To treat turf in its water dispensable granule formulation, apply 0.1 to 0.25 oz. of Compass 50 WG Fungicide in 1 to 2 gallons of water per 1,000 sq. ft. depending on the disease. To treat turf in its water soluble packet formulation, use 0.1 oz. (less than half of 1 packet) of product in 1 to 2 gallons of water per 1,000 sq. ft. Each water soluble packets is 8 oz. Foliar disease control on ornamentals will use 1-4 oz. of water dispensable granule product formulation per 100 gallons of water. Damping off of new seedlings, use 1/2 oz. of product per 100 gallons of water. Refer to the label for specific application rates and restrictions.
- Step 2: To prepare the spray mixture, drop the required number of unopened packets of Compass 50 WG Fungicide into the spray tank while filling the water to the desired level. Operate the agitator while mixing. Depending on the water temperature and the degree of agitation, the packets should be completely dissolved within a few minutes from the time they were added to the water.
- Step 3: Once mixed, spray the Compass 50 WG Fungicide mixture to the top and bottom of foliage leaves to the point of drip. For soil-borne diseases, spray this product until the crown and upper root zone of plants is treated. Apply to turf after mowing OR allow sprayed area to completely dry before mowing. For control of both foliar and soil-borne diseases, allow sprayed area to completely dry before irrigation.

When to Use
