It manages numerous annual grass, certain annual broadleaf weeds, and yellow nutsedge. It can be sprayed over the top of ornamental plants for control. This product is compatible with mixing with water or liquid fertilizers. It can be used alone or rotated with other herbicides to prevent resistance.

For ground applications, apply SpiruS alone or in a tank mixture by ground equipment in a minimum of 10 gallons of spray mixture per acre, unless otherwise stated.
Use sprayer that provide accurate and uniform application. For SpiruS tank mixtures with wettable powder or dry flowable formulations, screen, strainers should be no finer than 50-mesh. Rinse spray thoroughly with water after us. See product label for calculating the amount of herbicide needed for band treatment.
For aerial applications (sod farms only),apply SpiruS in water alone or in tank mixtures with atrazine, simazine, or other herbicide registered for use on sod farms in a minimum total volume of 2 gallon per acre by aircraft. See the label's Turfgrass section for listing of applicable warm-season grass. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. In order to assure that spray will be controllable within the target area when used according to label directions, make applications at a maximum height of 10 feet, using low-drift nozzles at a maximum pressure of 40 psi, and restrict application to periods when wind speed does not exceed 10 miles per hour.
To assure that spray will not adversely affect adjacent sensitive non-target plants, apply SpiruS or SpiruS mixtures at a minimum upwind distance of 400 feet from sensitive plants.
Avoid application to humans or animals. Flagmen and loaders should avoid inhalation of spray mist and prolonged contact with skin.
