FLOWER THINNING AGENT

摘要

A flower thinning agent comprising preparation of a mixture of an inorganic compound of poor solubility in water and an additive characterized in that the flower thinning agent satisfies the relationships: 0.03 <= P <= 30 (a), 3 <= Q <= 800 (b) and 0.5 <= Q/P <= 1000 (c) wherein P represents an average particle diameter (mum) measured by SALD2000A laser type particle size distribution meter and Q represents BET specific surface area (m2/g) measured according to the nitrogen adsorption method. The flower thinning agent is safe for human health, exhibits high adaptability to spread timing deflection and further exhibits high flower thinning efficiency.
