-298. CONTROLOF SEEDLING GRASSES IN TURF WITH DI~&NYLACETONITRILE, ,AND A SUBSTITUTEDDINITROANILINE -', ' . ' ',' 1 1 E. F.Alder, fl-.L. Wright. and Q. F. Soper.:::t --- Introduction Over the course of two seasonaa to,tal of .32 turf field tests containing over 1,00 plots were conducted in order to evaluate two herbicidal materials for their selective action against 'seedling grasses in turf. The first of these materials is diphenylacetonitrile which was coded aa L-l.3489 .ndilowhas the tentative generic name diphenatrile. The second is N,N-di(n-propyl)-2,6. dinitroaniline which was coded as L-.31864. No generic name has as yet been coined for this material, and it will continue to be ref$rredto here as L-.31864. , Procedure ,Fie.ld tests were placed in areas known to be heavily intested with seedling weed grasses 'the preoeding year. In one test location the turf was disturbed the preceding tall in order to leave open areas for weed grass infestation the following spring. Smooth crabgrass (Digitaria isohaemum) was the dominant weed grass in most plots. Hairy crabgrass (D. sanguinalis), yellow and green foxtail (Setaria lutescens and ~. viridis) and goosegrass (Eleusine indioa) were present in several of the plots. In each test all treatments were replicated tour times in a randomized block design. Turf plots were four by six feet. Two-foot buffers were lett between plots and four-foot bufters between replications. The seedling grasses in four foot-square quadrats in each plot of the tour replications were counted and averaged. In test areas of low weed infestation, entire plot counts were made. The tinal oount was taken 60-100 days atter treatment in the first of the test seasons, and 120-140 days after treatment in the second test season.
