FLOWER THINNING AGENT

摘要

The flower thinning agent of the present invention comprises a preparation of a mixture of an inorganic compound of poor water solubility with an additive, satisfying the following relationships of (a) 0.03≤P≤30, (b) 3≤Q≤800, and (c) 0.5≤Q/P≤1000, wherein P: average particle diameter ( mu m) measured by SALD-2000A laser type particle size distribution meter, Q: BET specific surface area (m<2>/g) measured according to the nitrogen adsorption method. The flower thinning agent of the present invention is not harmful to a human body and has not only high adaptability to the deflection of spread timing, but also high flower thinning effect.
