Summary
BREAKING ING THE WEED D RESIS ISTANCE TANCE CYCL CLE Drift of spray into non-cropland border areas is well known as drift measurements under normal conditions vary from 1-15% of target application at 1m from the last spray nozzle. While shown to be highly predictable, drift is also highly variable because of dependence on droplet size in addition to wind speed and release height. While a 1000 micron droplet drifting 4.7 feet in a 3mph wind from a release height of 10 feet, a 5 micron droplet will travel 3 miles under the same conditions INCREASED USE LOW VOLUME LOW VOLUME HIGHER RELATIVE WEED SHIFT IN WEED APPEARANCE OF GLYPHOSATE LEADS TO DRIFT LEADS TO DRIFT EFFICIANCY ON NEWLY DISTURBED FOLLOWS GRASSES AREAS CHARACTERISTIC PATTERN
DICAMBA RESISTANT PIGWEED TRIAL • Text Through experimentation in the greenhouse, we selected a population of pigweed that is tolerant to herbicide dicamba at a field rate. This pigweed population was not found to be resistant to dicamba in nature or in any field. Researchers exposed three generations of dicamba-susceptible GREENHOUSE EXPERIMENT DESIGNED TO pigweed collected from the field to sublethal doses of dicamba EXAMINE POTENTIAL FOR (conditions for resistance development) FUTURE RESISTANCE
Outline RESISTANCE EVOLUTION • Text Field screening indicated that no major-effect resistance genes were present in 100 million individuals. Resistance was obtained by recurrent low-dose pyroxasulfone selection of multiple herbicide-resistant L. rigidum. The multiple- resistant MR population showed a clear capacity to evolve pyroxafulfone resistance with >30% plant survival at 240 g ha-1 (2.4-fold the recommended rate after three generations of recurrent selection.)
