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.

Multi-layer barrier preventing wood pest access to wooden structures

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.

Sustained release pest control products and their applications

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.

Methods and products to protect against root intrusion and plant and root growth

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.

Method and device for protection of wooden objects proximate soil from pest invasion

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.

Method and apparatus for providing long term protection from intrusion by insects and other cold blooded animals

A method for creating an wood destroying organism resistant coating is disclosed. The method involves spraying a structure with a mixture of a quick setting liquid monomer and a pesticide. The monomer, when cured, forms a bonded polyurethane coating upon the surface a structure which slowly releases pesticide over long periods of time. The method may be practiced as a two part system utilizing monomers and catalytic curing agents, and a one part system utilizing masked isocyanates.

Method for applying pesticides and repellents

A method and device are disclosed which prevent the intrusion of insects into structures by using a controlled release device capable of releasing insecticide. In the disclosed method, the device maintains a minimal effective level of insecticide for a predetermined period of time.

Termite and boring insect barrier for the protection of wooden structures

A method and device are disclosed which prevent the intrusion of insects onto wood structures by using a controlled release device capable of releasing insecticide. In the disclosed method, the device maintains a minimal effective level of insecticide for a predetermined period of time.

Barrier preventing wood pest access to wooden structures

A method and device are disclosed which preventing 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.

Protection of wooden objects in direct contact with soil from pest

A method and device are used for controlling growth of plants in pavement splits by preventing seeds from germinating and by preventing growth of plants from existing roots in the vicinity of the splits. The growth of plants is controlled for extended periods of time (2 to 20 years). A pre-emergence herbicide and a systemic herbicide are incorporated into a polymeric matrices. The polymeric matrices are formed into shaped objects, such as, bands or cords which are then inserted into splits. The split is then filled with a sealer which permits easy migration of the herbicides therethrough. The herbicides gradually released from the shaped objects at a rate sufficient to maintain a minimal effective level of herbicide outside said sealer for a predetermined period of time.
