IN view of the widespread use of hormone-type herbicides on mixed stands of crop plants containing clover as an essential constituent, it would appear to be of considerable importance to determine the effect of these substances on the growth of the clover nodule-forming organism. This is particularly true of the phenoxybutyric compounds which have been recommended for use as herbicides where clover is present, since they have been shown by Wain1 and other workers to have no harmful effect on clover due to the latter's lack of the β-oxidizing enzyme system.
