| Abstract/Contents: | "The objective of this study was to differentiate of acetyl CoA carboxylase (ACCase)-inhibiting herbicides resistance in southern crabgrass. Populations of the ACCase-resistant southern crabgrass (R1R and R2) were collected from sod production fields in Georgia. A susceptible (S) population with no known history of exposure to any ACCase-inhibiting herbicides was collected from Alabama. Leaves of southern crabgrass from R1, R2, and S phenotypes were placed in separate tubes containing the four-discriminating dose of herbicides (0.8, 1.6, 3.2, and 6.4 µM). Leaves from each phenotype were placed in each tube and four tubes were used per treatment. Herbicides absorption of each leaf was evaluated at 12 hours after treatment with electroconductivity (EC) test. Both R1 and R2 were more resistant to sethoxydim than the others. The leaves of resistant phenotypes floated at the lower concentration to the surface, whereas the leaves of susceptible phenotypes failed to float within 12 hours after treatment. The susceptible phenotype contained higher EC value than the resistant phenotypes. This bioassay is effective in detecting ACCase-resistant population with target-site resistance mechanisms. Moreover, it can be used to detect large numbers of plants to determine the resistance to ACCase-inhibiting herbicides without destroying the whole plants or preventing reproduction." |
