361. The most e.ffective chemicals in reduc1llg the weed pOpulation were Neburon and Eptam. These were followed by 2,4-D amine, Sinox P.E"AC~ L-685, ACPL-688, MoPamine, 4(2~4-DB) and ACPL-119· Except for the Fenuronand 2, 4-D plots, there was no evidence of aI:\Y effect on the emergence and ~stablishme~t of the alfalfa seeding. .. . . : The best stands of seedling alfalfa were obtained on the Neburon,Eptam and Sinox P.E. plots, with Neburon being exceptional. Throusllout the growing season, there was no weed growth, oats or legume 4evelopment on the Fenuron plots. Observations during the growing season did not show any injury to the oats" pap.1cle development or maturd:ty. The yield of oats and the ir test weight were affected. SUMMARY: Pre-emergence treatments show promise for the control of early germinating weeds in oats and the associated legume seeding. The only species not controlled was ragweed (Ambrosia artemisiifolia), and the perennials such as: Ground Cherry (Physalis subglabrata), Flower ..of-the-Hour (Hibiscus trionum) Horse Nettle (Solanum ~arOl1nens~), andquackgrass.
