Latest Patents
One of Yang's latest patents is titled "Preparation of pesticide microcapsule." This invention relates to a novel method for preparing pesticide microcapsules in which the release rate and the release period of the pesticide are controlled. A process has been discovered for encapsulating a trace amount of pesticide with a urea-formaldehyde resin, mechanically stirring the resin in the presence of vegetable oil and the pesticide, and reacting the mixture under suitable conditions to form a desired pesticide microcapsule.
Another significant patent is "Controlled-release pesticides and methods for preparation and use thereof." This invention provides a particulate controlled-release pesticide composition having a pesticide encapsulated in a polymer matrix of starch-borax-urea. The release rates and release duration of the pesticide compositions are controllable by adjusting the urea content in the compositions. The pesticide composition is preparable by admixing starch, pesticide, urea, and water together to form a mixture and agitating the same at a temperature sufficient to gelatinize the mixture and to disperse the mixture. Borax is then added to the mixture in an amount effective to convert the mixture into a rubbery mass. The rubbery mass is then comminuted into small particles, in the presence of added starch, and dried.
