Abstract: A method of forming an active control ingredient that controls target living species over an extended period of time commences by providing a clay material that has a structure substantially depleted of platelets (“aplatelet”). The aplatelet clay material is heated with a solid active control agent to a temperature of at least about 10° C. above the melting point of the solid active control agent. The aplatelet clay material then is loaded with the heated solid active control agent.

Abstract: A method to control on a sustained basis insect pests wherein the insect pests are exposed to repellent chemicals lodged in a high tortuosity microporous polymeric material.

Abstract: A method and device are disclosed which prevent the intrusion of insects onto wood structures by using a barrier capable of retaining pesticide. In the disclosed method, the barrier maintains a minimal effective level of insecticide for a predetermined period of time.

Abstract: This invention provides repellent devices and methods for control of root intrusion and plant growth. One aspect of this invention is a geotextile in which 2,6-dinitroaniline is stored inside the individual filaments. The 2,6-dinitroaniline is stored in nanoclay or smectite clay reservoirs that control the rate of release of the 2,6-dinitroaniline. These reservoir particles are placed in the fibers during the melt spinning production of the fibers or by film-to-fiber processes. The particles are very thin and are oriented within the fibers during the spinning process. These clay reservoirs are superior to conventional carbon-based reservoirs, because the dispersed clay materials have a uniform, e.g., 1-nanometer, thickness that is needed to fit into individual filaments. Nonwoven, woven, or knitting processes are used to make the geotextile fabrics. The fibers of this invention prevent root intrusion into these fabrics.

Abstract: A method for applying a barrier to a structure to prevent the infiltration of pest species includes providing a composition and associating the coating composition with the structure. The composition is formed from a polymer component having dispersed therein beads formed from colloidal clay and adsorbed pest control agent. Colloidal clays (e.g., nano-clays) adsorb more pest control agent that do standard clays and releases the adsorbed pest control agent at a slower rate than do standard clays.

Abstract: A method for applying a barrier to structures to prevent the infiltration of pest species (unwanted organisms) uses a (e.g., coating) composition formed from a polyurethane (e.g., film-forming) polymer system and a pellet comprising a pesticide incorporated into a sorbent and dispersed in the polyurethane polymer system. The composition protects the structure by application either to the structure or to a pathway that leads to the structure. Advantageous polymer systems include polyurethanes rich in urea linkages and predominating in aliphatic and alicyclic backbones.

Abstract: One aspect of the present invention is a sprayable composition for coating pipe for protecting it from one or more of root intrusion or root growth when the coated pipe is placed underground. Such sprayable formulation includes a 2,6-dinitroaniline herbicide; a polymer pellet impregnated with a 2,6-dinitroanililne herbicide-sorbed colloidal clay; and a film-forming polymer. Another aspect is pipe coated with the dried residue of a coating of a 2,6-dinitroaniline herbicide; a polymer pellet impregnated with a 2,6-dinitroaniline herbicide-sorbed colloidal clay; and a film-forming polymer, wherein the coated pipe is protected from one or more of root intrusion or root growth when the coated pipe is placed underground.

Abstract: A method and device are disclosed which prevents the decay and deterioration of wooden objects caused by pests by using a controlled release device. This controlled release device utilizes polymers which incorporate pesticides. In the disclosed method, the controlled release device is placed in contact with the wood of the wooden object. The pesticide is gradually released from the device and absorbed into the wood structure. The pesticide absorbed by the wood creates a barrier or an exclusion zone to penetration by inserts. The controlled release device maintains a minimal effective level of pesticide in the barrier or exclusion zone for a predetermined period of time.

Abstract: One aspect of the invention is a method of controlling target living species with an active ingredient over an extended period of time. This method sorbs an active ingredient into colloidal clay. Next, a polymer pellet recalcitrant to release of the active ingredient is loaded with the sorbed colloidal clay. Finally, the loaded polymer pellet is formed into a barrier, which is adapted to be placed at a location for controlling a target living species. Another aspect is a barrier for controlling a target living species. The formed barrier contains polymer pellets loaded with colloidal clay sorbed with an active ingredient that controls the target living species. The sorbed clay loaded polymer polymer pellets are recalcitrant to release of the active ingredient.

Abstract: Controlled release devices are shaped and placed in locations through which insects and/or other cold blooded animals generally enter an area or a structure sought to be protected. The controlled release devices include a polymeric matrix and a pesticide contained in the matrix. The pesticide is gradually released out of the matrix to the surface of the device. The pesticide on the surface of the device kills the intruding insects or other cold blooded animals that come in contact with the pesticide. In addition, if the device is in contact with a permeable structure or object, the pesticide released onto the surface of the device is absorbed by such permeable structure or object to provide a barrier to entry by the insects and/or other cold blooded animals.

Abstract: A multi-layer wood pest barrier having a prolonged lifetime that can be as long as the life of a building or structure to be protected. The lifetime protection is achieved by binding at least one pesticide within a continuous or discontinuous polymer matrix layer thereby substantially reducing release of the pesticide from the matrix. The release rate of the pesticide from the matrix can be controlled by the use of a carrier such as carbon black. The release of the pesticide from the barrier can be further controlled by inclusion of additional layers which can make the barrier substantially non-releasing.
