Technical Abstract: Particle Film Technology involves establishing a mineral particle film on the surface of a plant or plant product that: (1) is chemically inert, (2) has a mean particle diameter < 2 um, (3) is formulated to spread and create a uniform film, (4) does not physically disrupt gas exchange from the leaf, (5) transmits photosynthetically active radiation (PAR) to and partially reflects harmful ultraviolet (UV) and infrared (IR) radiation from the surface, (6) alters insect and/or pathogen behavior on the plant, and (7) can be removed from the plant or plant product. Particle Film Technology was developed using chemically inert kaolin mineral particles in aqueous formulations for application to crop plants to protect them from insect pests and environmental stresses. Field research demonstrated this technology effectively provides a safe alternative to conventional insecticides for certain insect problems on a wide range of crops including apple, pear, grape, blackberry, melons, tomato, onions, papaya, peach, nectarine, olive, pineapple, and citrus. Surround Crop Protectant is the first particle film product to provide effective suppression of high heat damage and sunburn without the use of evaporative cooling. In organic agriculture, Particle Film Technology represents the first broad utility material that provides effective insect control and high produce quality in organic fruits and vegetables. Particle Film Technology represents a broadly-based insect control system whose impact could be similar to the development of the first synthetic insecticides but without the adverse effects on ecosystems. Additionally, Particle Film Technology provides agriculture with the first sunburn and heat management tool that can manipulate ultraviolet, photosynthetically active and infrared radiation.
