The rate for Arena .25 Granules per the product label on shrubs is 0.5 to 1.0 lb/ft of height 5 to 10 lbs per 10 cumulative ft of height. For treatment of individual shrubs or trees, broadcast Arena 0.25 G Insecticide evenly on soil around base of plant within 18 inches of the trunk. Pull back mulch prior to application if mulch is more than 1 inch thick. Irrigate after application with enough water to dissolve granules and move product into root zone.
