# 180.1056 Boiled linseed oil; exemption from requirement of tolerance.

Boiled linseed oil (containing no more than 0.33 percent manganese naphthenate and no more than 0.33 percent cobalt naphthenate) is exempt from the requirement of a tolerance when used as a coating agent for *S*-ethyl hexahydro-1*H*-azepine-1-carbothioate. No more than 15 percent of the pesticide formulation may consist of “boiled linseed oil.” This exemption is limited to use on rice before edible parts form.
