Sinochem News reported that the US Environmental Protection Agency recently proposed to approve the plant growth regulator (PGR) product Blush of FineAgrochemicals. The active ingredient of Blush is propyl jasmonate (PDJ), which is used to improve the color of red apple.

Propyl jasmonate is a synthetic plant growth regulator, which is similar in structure to jasmonic acid (JA), a natural plant regulator commonly found in vascular plants, with the same function and similar action mode, and low toxicity to the environment.

The United States Environmental Protection Agency received Blush's registration application in December last year, and the public review period for this approval ended on October 3, 2013.
