In addition the instructions as to treatment of balled nursery stock by methyl liromide .solution as specified in paragraph (ii) of subsection (b) are somewhat modified as to treatments within the regulated areas other than New Orleans and vicinity. All treatments apply to both species of white-fringed beetles, Pantomorus leucoloma Boh. and Pperegrinus Buch., and are uniformly applicable to all regulated areas except the methyl bromide solution treatment of balled nuraer s stock, the specifications of which vary for the New Orleans area because of the type of soil in that locality.
