Each word in such label shall be legibly printed in letters not less than one-half inch in height.
(b) An alternate manner for container and other labeling information as required under subsection (a) of this section may be prescribed by the Board of Agriculture and Industries pursuant to rules and regulations which shall be consistent with the evident intent and purposes of this section.
