PURPOSE: A burst type delay emission controlling composition is provided to emit a biological active component in the composition when a rainy season sets in whereby a biological active component can applied at an appropriate period. CONSTITUTION: A burst type delay emission controlling composition which as an initial emission delay characteristic includes a center part which has a water-expandable polymer and biological active components in the water-expandable polymer； and a peripheral part which is formed on the surface of the center part to surround the center part and is water-permeable. A manufacturing method of the delay emission controlling composition includes a step of adding acids into the water-expandable polymer to control the pH of the water-expandable polymer to 5.0-6.0, mixing the water-expandable polymer with a microbial cell, and freezing and drying the mixture to prepare the center part； and a step of spraying magnesium sulfate onto the center part and drying the same and spraying a peripheral part-forming solution to form the peripheral part.
