| Abstract: The effect of Gallery application timing on dwarf burning bush tolerance was determined in field trials. Gallery was applied foliarly at 0.84, 1.69 and 3.39 kg ai/ha (0.75, 1.5 and 3 lb ai/A) to dwarf burning bush at different growth stages. Gallery applied at the dormant stage and two months after bud-break did not injure dwarf burning bush. Plants treated one month after bud-break with all three rates were injured approximately 30 to 45% at one and three months after herbicide application. Injury symptoms were manifested as decreased leaf size and leaf distortions. Gallery applied at 0.84 and 1.69 kg/ha (0.75 and 1.5 lb/A) one month after bud-break decreased plant width. Shoot-dieback was also observed in plants treated with Gallery at all rates one month after bud-break. Gallery at all three rates applied one month after bud-break caused 60 to 75% of the leaves to defoliate six weeks earlier in the fall compared to the other application timings. |
