<p>A pulse release pesticide granule characterized in that it has at least one hydrophobic coating film layer containing silica. The present pesticide granule allows the control of release rate to an almost constant value without depending on the lag time from the application of the pesticide to the start of release. Therefore, problems such as lowering of expressivity of pesticide effect in using a pulse release pesticide granule can be avoided.</p> |
