      A test was conducted to compare EPTC applied preplant to alfalfa as a 10% granule and as a emulsifiable concentrate metered into the irrigation water. Observations and measurements on weed control and phytotoxicity were recorded EPTC appeared to be more active in controlling weeds and injuring seedling alfalfa when applied to 3.0 lb./acre as a granule rather than the same rate applied as a water run.
