Preparation of pesticide microcapsule |
摘要 |
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.
