Use a tank, an Ortho® Dial 'N Spray®, or other hose-end sprayer. Spray to uniformly cover all upper and lower leaf surfaces, stems, branches and trunk. Mix 2 1/2 oz. per gallon of water during growing season or 5 1/3 oz. per gallon of water during the dormant season.
Spray when air is calm to avoid drift. Spray when temperature is above 40°F but below 85°F. If temperature is expected above 85°F, spray in early morning or late afternoon when it is cooler. During the growing season, spray when insects are present or feeding injury is first noticed. Spray up to 4 times, waiting 2 weeks between each application. During the dormant season, spray dormant shrubs and trees once in late winter or early spring.
For outdoor use only. On conifers, roses, shrubs and trees, including apples, apricots, cherries, peaches, pears, plums and citrus (grapefruits, lemons, limes, oranges and tangerines).
Maidenhair ferns, red maples, Japanese maples or non-woody plants unless otherwise specified. Volck® Oil Spray may cause discoloration to blue spruce.
Insects: Spider mites, scales, mealybugs, whiteflies, hemlock woolly adelgids and lacebugs, insect eggs (including codling moth, gypsy moth, oak moth, spider mite and tent caterpillar eggs) plus sooty mold.
