Made from calcined kaolin clay, this white coating for plant surfaces suppresses insect pests and reduces heat stress and sunburn. Use on fruit and nut trees, vegetables, and field crops prior to infestation and as protection. Developed by the USDA, its micro-particulates link together to form a semi continuous porous "particle film" barrier that protects your fruits, vegetables and foliage but doesn't block light. Tank mixes with most other pest control products except dormant oil. Mixes well with lime-sulfur and wettable sulfur used for disease control. It is best to apply when bees are not actively foraging. Repeat applications as needed. Read more about the use of Surround in The Holistic Orchard by Michael Phillips and in Organic/Low-Spray Peaches from ATTRA.
