These experiments show that with the use of a particular application technique, DBCP (1,2-dibromo-3-chloropropane) effectively reduces the nematode population around the roots of greenhouse rose plants. The reduction in population of these nematodes in the soil also resulted in increased flower production. At the end of the 26th week after the first treatment there were approximately 13,000 more blooms per acre in the Pink Sensation variety plots, and 19,000 more blooms per acre in the Golden Wave plants, as compared with the untreated check plots.
