| Abstract/Contents: | "Acifluorfen has been documented to decrease efficacy of fluazifop-butyl in several annual grasses when the two compounds are applied in tank mixture. In Louisiana, no antagonism between the compounds has been observed in itchgrass, while dramatic antagonism has been shown in large crabgrass. In 1984, research was initiated in the laboratory to determine if the antagonism of acifluorfen on fluazifop-butyl was due to a decrease in absorption of fluazifop-butyl into the plant surface or translocation within the plant. 14 C-fluizifop-butyl was applied alone and in tank mixture with acifluorfen to a 1 cm2 area of the uppermost fully expanded leaf of itchgrass and large crabgrass. Plants were harvested 6, 24, 48, 120, and 168 hours following treatment. At harvest, the treated leaf of each plant was washed 3 times for 30 seconds with 0.25% v/v non-ionic surfactant in 100 ml distilled water. Plants were sectioned, lyophilized, weighed and then combusted for 4 minutes and trapped in 15 ml of 14CO2 absorbant. Ratioactivity of combusted samples and leaf washes were quantitated in a liquid scintillation spectrophotometer. In general, more 14C-label was absorbed when fluazifop-butyl was applied alone compared to a tank mixture with acifluorfen in large crabgrass. The relative amounts of 14C-label moved from the site of absorption were the same, indicating that acifluorfen was decreasing absorption, but not translocation of fluazifop-butyl. No differences were observed in absorption or translocation of 14C-label of fluazifop-butyl applied alone compared to the tank mixture with acifluorfen in itchgrass." |
