<p>PURPOSE: A coated powder particle containing one or more cyclopropene compounds is provided to delay the release of the cyclopropene compounds when the particle is mixed with water. CONSTITUTION: A powder composition contains a collection of particles (I) with a median particle diameter of 10-200 um. The particle (I) contains a covering of a fatty compound with a melting point of 50-110°C; and one or more complex containing a cyclopropene compound molecule or a portion of the cyclopropene compound molecule encapsulated in a molecule of a molecular encapsulating agent. The collection of the particle (I) has a median particle diameter of 10-100 um.</p> |
