Kaolin Clay (Surround)
Surround (kaolin clay) is a novel, nontoxic material that forms a mechanical barrier film to protect fruit against insect and solar damage. Surround is registered for use on pears, apples, and stone fruit. Surround suppresses insects by creating a protective white particle barrier on plant surfaces, which repels and irritates insects. For best results, the material should be first used before expected insect appearance and reapplied every 7 to 14 days throughout the season. Uniform and consistent coverage is essential for effective insect suppression and control. Special washing may be required at harvest to remove residue from fruit.
