Abstract/Contents: | PP-333 and flurprimidol were evaluated for growth retardation of a tall fescue alleyway in an apple orchard. On June 6, 1980, PP-333 50W was applied with a hand-held boom at rates of 2.2, 3.4 and 4.5 kg a.i./ha. PP-333 caused a significant height reduction for 14 weeks following application and eliminated 12 mowings. Plots were differentially discolored during this period with the most discoloration arising in plots treated with the highest rates of PP-333. In October, samples were removed from each plot and studied for morphological changes. PP-333 at the 3.4 kg a.i./ha rate increased tiller density by 54%. PP-333 applications also increased the number of leaves per tiller and increased leaf widths. The highest rate reduced leaf length. Flurprimidol 50W was applied to the area on June 6, 1981, at the same rates as PP-333. In 1981, the treatments decreased canopy height for 12 weeks and improved color ratings. Samples removed in 1981 showed tiller density to be increased by the 4.5 kg a.i./ha rate. |
