The potential of compound U-12171 as an avian repellent


Tests of the effectiveness (primarily reduced plant damage) of U-12171 to repel linnets from, or reduce the amount of feeding damage on, Gem hybrid broccoli suggest that: 1) concentrations above 1.50 lb./acre deterred avian depredations whereas lower concentrations did not; 2) the "hop-scotch" feeding pattern of linnet groups may have contributed to repellency since high concentrations in one area may act as a barrier to other areas; and 3) U-12171 efficiency may be markedly affected by chemical coverage of the plant, the number of applications made, and application timing relative to crop maturity.
