Growth responses of three annual clovers to treatments with 2,4-D—Part II

Applications of 2,4-D to annual clovers growing on the range in El Dorado County generally affected dry matter production of subclover much less than that of rose clover. Rose clover yield was higher when the treatment date was later, but was never higher than the untreated plots. The dry matter yields were significantly reduced by spraying at the high rate at either of the first two dates.
