2009 California Food and Agricultural Code - Section 14631 :: Article 8. Labels

14631.  Every lot, parcel, or package of fertilizing material
distributed into or within this state shall have attached to it, or
the shipment shall be physically accompanied by, a label as required
by the secretary, by regulation. The secretary may require proof of
labeling statements and claims made for any fertilizing material. As
evidence of proof, the secretary may rely on experimental data,
evaluations, or advice furnished by scientists, including scientists
affiliated with the University of California, and may accept or
reject additional sources of proof. The secretary shall cancel the
approval of, or refuse to approve, a fertilizing material label if
the secretary determines that adequate proof of label claims does not
exist. The secretary, after hearing, may cancel the license of any
person who distributes a fertilizing material with a label for which
approval has been canceled or a label that has not been approved by
the secretary.
