Fluazinam, propiconazole plus trifloxystrobin, or tebuconazole did not affect efficacy of clethodim or sethoxydim. Azoxystrobin, boscalid, chlorothalonil, and pyraclostrobin reduced efficacy of clethodim and sethoxydim in some experiments. Increasing the herbicide rate increased large crabgrass control regardless of the addition of chlorothalonil. In laboratory experiments,14C absorption was less when14C-clethodim or14C-sethoxydim was applied with chlorothalonil. Pyraclostrobin and tebuconazole did not affect absorption of14C-clethodim or14C-sethoxydim.}, number={2}, journal={WEED TECHNOLOGY}, author={Lancaster, SH and Jordan, DL and York, AC and Burke, IC and Corbin, FT and Sheldon, YS and Wilcut, JW and Monks, DW}, year={2005}, pages={397–403} }

Laboratory experiments were conducted on yellow foxtail (Setaria glauca) to determine the effect of mixing bromoxynil with the ethyl ester of quizalofop-P on absorption, translocation, and metabolism of14C-quizalofop-P Applying bromoxynil in mixture with quizalofop-P reduced14C-label absorption from 63 to 51%, 73 to 52%, 77 to 68%, and 90 to 80% at 4, 8, 24, and 96 h after treatment, respectively. Translocation of14C-label from the treated leaf into the shoot above or shoot below was unaffected by bromoxynil. However, translocation into the roots was reduced from 0.9 to 0.4% and 1.0 to 0.5% at 4 and 8 h after treatment, respectively, but differences were not noted at 0.5, 1, 24, and 96 h after treatment. Bromoxynil increased deesterification of quizalofop-P-ethyl into quizalofop-P acid from 45 to 60% in the shoot above the treated leaf. However, bromoxynil did not affect metabolism of quizalofop-P in the treated leaf or shoot below the treated leaf. These results suggest that antagonism of quizalofop-P activity by bromoxynil is primarily due to decreased absorption of quizalofop-P, whereas effects on translocation and metabolism were minor.}, number={3}, journal={WEED TECHNOLOGY}, author={Culpepper, AS and York, AC and Jordan, DL and Corbin, FT and Sheldon, YS}, year={1999}, pages={515–519} }
 @article{culpepper_jordan_york_corbin_sheldon_1999, title={Influence of adjuvants and bromoxynil on absorption of clethodim}, volume={13}, ISSN={["1550-2740"]}, DOI={10.1017/s0890037x00046169}, abstractNote={The effect of nonionic surfactant, crop oil concentrate, organosilicone surfactant, methylated seed oil, and a blend of organosilicone surfactant and methylated seed oil on absorption of14C-clethodim was evaluated in barnyardgrass (Echinochloa crus-galli). Absorption of14C-label was greatest during the first 40 min after application when14C-clethodim was applied with methylated seed oil or a blend of methylated seed oil and organosilicone surfactant. These adjuvants increased the rate of absorption more than crop oil concentrate, organosilicone surfactant, or nonionic surfactant. Crop oil concentrate was more effective than organosilicone or nonionic surfactant in increasing absorption, with nonionic surfactant being more effective than organosilicone surfactant. These results generally agreed with the order of increasing efficacy of clethodim on barnyardgrass as affected by adjuvants in field experiments. Another study was conducted to determine the effect of bromoxynil on absorption and translocation of14C-clethodim in yellow foxtail (Setaria glauca). Bromoxynil reduced absorption of14C–clethodim 4, 8, and 24 h after application and also reduced the amount of14C-label translocated from the treated leaf. These data suggest that antagonism of clethodim control of yellow foxtail by bromoxynil observed in previous research can be attributed partially to decreased absorption and translocation of clethodim.}, number={3}, journal={WEED TECHNOLOGY}, author={Culpepper, AS and Jordan, DL and York, AC and Corbin, FT and Sheldon, Y}, year={1999}, pages={536–541} }
