| Abstract/Contents: | "Triclopyr reduces foliar bleaching from mesotrione and may enhance efficacy for controlling multi-tiller smooth crabgrass. The objectives of this research were to evaluate the influence of triclopyr on the efficacy, absorption, and translocation of mesotrione in multi-tiller smooth crabgrass. In field experiments, tank-mixing triclopyr (560 or 1120 g ae ha-1) with mesotrione at 140 g ai ha-1 applied sequentially or at 280 kg ha-1 applied singly provided excellent control (>90 percent) of multi-tiller smooth crabgrass in tall fescue. These treatments were more effective than mesotrione alone and fenoxaprop at 195 g ai ha-1 that averaged 66 percent and 81 percent control after 6 wk, respectively. Mesotrione alone at 280 g ha-1 bleached crabgrass 53 percent at 2 weeks after initial treatment (WAIT), and was 14 percent greater than the 140 g ha-1 treatment. Sequential treatments of the low mesotrione rate bleached crabgrass shoots 16 to 22 percent from 3 to 5 WAIT, but bleaching was <5 percent from the high rate after 4 wk. Triclopyr tank-mixtures reduced crabgrass bleaching on all dates to <5 percent. Tall fescue injury was not detected at any evaluation date. In laboratory experiments, smooth crabgrass reached peak foliar absorption of 14C-mesotrione at 168 and 24 hours after treatment (HAT, 15 percent and 23 percent) when mesotrione was applied with triclopyr at 0 and 1120 g ha-1 , respectively. Triclopyr reduced translocation of radioactivity by 12 percent at 72 and 168 HAT, compared to 14C-mesotrione alone. Enhanced foliar uptake of mesotrione from triclopyr tank-mixtures may improve control of multi-tiller smooth crabgrass, as compared to mesotrione alone. Reduced foliar bleaching from triclopyr is associated with less translocation of mesotrione or derivatives by smooth crabgrass." |
