AGROCHEMICAL SLOW-RELEASE MATERIAL, VEGETATIONAL STRUCTURE AND CONTINUATION OF AGROCHEMICAL EFFICACY

摘要

PROBLEM TO BE SOLVED: To obtain a material capable of continuing the agrochemical efficacy for an ultralong period of time. ;SOLUTION: An agrochemical slow-release partial material 1 which includes an agrochemical and is put at peripheral places 5 around plants 2 to gradually release the agrochemical is provided. This agrochemical slow-release partial material 1 is composed of moldings consisting of at least one kind of polymeric materials selected from the group consisting of rubbers and plastics, and at least one kind of agrochemicals is blended with the raw material of this moldings. When this agrochemical slow-release partial material 1 is put at the peripheral places 5 near the plants 2, the agrochemical contained in it is gradually released and the agrochemical efficacy can be continued for an ultralong period of time, i.e., half a year or more than one year.;COPYRIGHT: (C)1999,JPO
