| Abstract/Contents: | Creeping speedwell is commonly found in many lawns, parks, golf courses, and cemetaries in the northeastern United States. Recently, DCPA has been labeled for creeping speed- well control at 17.9 kg/ha from the wettable formulation. Other materials are also being evaluated at various locations. An experiment was conducted in 1978 on the campus of The Pennsylvania State University using DCPA, ACR 1255, and a combination of 2,4-D, MCPP, and dicamba in single and split applications for creeping speedwell control. Results of this study were reported in The Proceedings of The Northeast Weed Science Society in 1979. On August 20, 1979, the 1978 test was rated for creeping speedwell encroachment. Turf treated with a single application of the 2,4-D, MCPP, dicamba combination had approximately the same amount of creeping speedwell as on September 12, 1978 (which was nearly the same as the amount that existed prior to treatment). Reapplication of the 2,4-D, MCPP, dicamba combination during 1978 kept the creeping speedwell population below the original level and no increase in encroachment occurred during 1979. Control from both ACR 1255 application rates was good through September 12, 1978, however by August 20, 1979, the creeping speedwell population had increased. The percentage of creeping speedwell in the plots was still below that which occurred in turf treated with either of the 2,4-D, MCPP, dicamba combination treatments. Both DCPA treatments provided excellent control through September 12, 1978. Some re-encroachment occurred during 1979, but for both treatments, creeping speedwell was not greater than 20% of the population. For efficacy and longevity, DCPA appeared to be the best treatment for creeping speedwell control, but re-encroachment data indicate that complete control may require additional applications in ensuing years. |
