Title: Innovations by David R. Sjogren in Pest Control Technologies
Introduction
David R. Sjogren is an accomplished inventor based in Sherwood, OR (US). He has made significant contributions to the field of pest control through his innovative inventions. With a total of 3 patents, his work focuses on sustainable and effective methods for managing pest populations.
Latest Patents
One of his latest patents is titled "Sustained release microbial insect control composition and means." This invention describes a method for achieving effective sustained release of microbial pesticides in aquatic environments. By combining buoyant particles with a particulate microbial active ingredient, the resulting materials can be formed into granules or pellets. These compositions dissolve slowly in water, releasing buoyant pesticide-laden particles that target immature filter-feeding mosquitoes and pestiferous flies.
Another notable patent is "Controlled release of S-methoprene and other active ingredients with activated carbon." This invention utilizes activated carbon as a release agent for liquid pesticides. The pesticide is adsorbed into the carbon's mesopore and macropore spaces. Upon contact with water, the pesticide is gradually released into the environment, providing effective pest control. This technology allows for the use of various pesticides, including insecticides, herbicides, and fungicides.
