Kaolin Clay May Be Viable Option to Protect Citrus Trees from ACP

Daniel CooperCitrus Greening, Industry News Release, Psyllids, Research

Florida citrus growers have begun taking notice of kaolin clay, a powdery white compound, because it can cause Asian citrus psyllids (ACP) to “not take notice” of their groves. Long used to protect other fruit and vegetable crops, kaolin can also conceal citrus trees from hungry psyllids by confusing their visual sensory system, said Michael Rogers, director of the Citrus … Read More
