Use 2 2/3 oz. or half gallon of water to treat 250 sq. ft. Start treating when grass begins to turn green in the spring or when signs of diseases are first noticed. For best disease control treat every 2 weeks.

Determine the size of the lawn to be treated. To calculate square feet, multiply length by width. Start at the farthest point to be treated and work backward so you don’t walk over treated area. Walk at a steady pace and spray using side to side (arc) motion, slightly overlapping the treated area.



Use 3/4 oz./gallon of water. Apply to the point when spray just begins to runoff the leaves. Apply once every 2 weeks throughout the season or until conditions favoring disease development (hot, moist weather) are no longer present. Allow spray to dry before watering.


  1. Treat roses on a 7 to 10 day schedule. If black spot is not a problem, a 10 to 14 day schedule is recommended.
  2. When treating azaleas, mountain laurel or rhododendrons, begin spraying when flowers start to show color.
  3. When treating irises, increase use rate to 1 1/2 oz./gallon of water.
  4. For Douglas fir, loblolly pine and slash pine use 2 1/4 oz./gallon of water. Begin treating in early spring and continue treating every 2 to 3 weeks until threat of infection has passed.


Mix 1/3 oz. with 1 gallon of water and uniformly apply to all parts of the tree to point of runoff. For anthracnose, blossom blight, and shothole, apply at pink bud stage (when about 5% of the buds have bloomed). If conditions favoring disease development (hot, moist weather) exist, reapply at full bloom and when the petals fall. For rust, apply 8 weeks after flowering if conditions favoring disease development exist. Reapply every 21 days so long as disease symptoms persist.
