From: High Levels of Glyphosate Resistance in Conyza canadensis from Agricultural and Non-Agricultural Sites in Ohio and Iowa

Figure 2

Locations of maternal Conyza canadensis (horseweed) biotypes with glyphosate resistance levels and habitats in Ohio (a) and Iowa (b). Locations with triangles (▲) correspond to biotypes from agricultural habitats and circles (●) correspond to non-agricultural habitats. Biotypes were grouped into glyphosate resistance rankings based on 80% survival at 0x only (S = Susceptible), and up to 1x (R1), 8x (R2), 20x (R3), and 40x (R4). Biotype locations were separated by at least 1.6 kilometers. Maps were generated using ArcGIS® software ver. 10.2.2 for Desktop (Environmental Systems Research Institute Inc., www.esri.com).
