69. CONTROLOF WEEDSIN VEGETABLECROPS WITH A SUBSTITUTEDDIPHENYLACETAMIDE E. F. Alder, W. L. Wright, and Q. F. Sop~rl/ Introduction Extensive studies in the greenhouse and field have been conducted on a l~rge number of substituted diphenylacetonitriles and diphenylacetamides. Special a;ttention has been given to a neW selective herbicide, N,N-dimethyl-~,~-diphenylacetamide. This compound was coded as L-343l4 and now bears ,the tenta~ive generic, name diphenamid. In greenhouse tests diphenatl11.dgave good pre-emergent activity against all seedling grasses tested and against broadleaf weeds such as pigweed and smartweedat rates of 4, s»)«, A number of important horticultural andagr.onomic- crops Were tolerant- to the material. Structure-ac1iivity stUdies reveaLed that lengthening the chain of the. alkyl substit'uents of the amide portion of dip hen amid resulted in reduced activity. . Field Tests The promising greenhouse results with diphenamid led to its inclusion in thirteen field tests on a total of 28 different crops. Major emphasis has been on tomatoes, other vegetable crops, and forage legumes. Diphenamid has a rather low solubility in water (260 ppm) and in most organic solvents. It was, theretore, formul.ated as a , wettable powd~r and on clay granul~s. Applications,f)f \ the wettable powder formulation were made with,a small: plot sulky spray rig. Granules were applied with a lawn -spreader •. Slightly 'better results were generally obtained with the wett.ble powder formulation. All field tests were replicated and of a randomized block design. Tomatoes -- Four pre-emergence field tests were conducted on tomatoes; three with field-seeded tomatoes, one with tomato transplants. In all tests, 4 to 6 lb/A of diph~namid gave satisfactory control of weed grasses with no damage to tomatoes. Table 1 11 Eli Lilly and Co., AgriCUltural ~esearch Center, Greenfield, Indiana
