Interpretive Summary:

Technical Abstract: Particle film technology was conceived by ARS scientists in the mid-1990's as an alternative to chemical pesticides. This technology was based on coating plant parts with mineral films that were chemically inert, could be formulated to spread and create a uniform film, formed a porous film that does not interfere with gas exchange between the leaf and atmosphere, transmits photosynthetically active radiation (PAR) but excludes ultraviolet (UV) and infrared (IR) radiation to some degree, alters insect behavior on the plant, and can be removed from harvested commodities. Research soon focused on kaolin-based particle film because of this minerals history of safety to humans. This review covers the development of particle film technology and the various particle film formulations that resulted. An overview is given on the mechanisms of particle films on insects and the current uses of particle films for insect control. In addition, other agricultural uses of particle films are covered, including sunburn protection for plants, frost prevention, and other applications.
