Experiment I | Evaluate effectiveness of imazapic applications in pasture-sized plots sown with a mix of NWSG (alone) or a mix of NWSG + WF. | NWSG (alone) Mix of NWSG + WF | Control: no imazapic Imazapic: 0.15 l/ha (2 oz/ac) |
Experiment II | Compare establishment of NWSG and WF at 4 different rates of imazapic application. | NWSG (alone) Mix of NWSG + WF | Control: no imazapic Low: 0.15 l/ha (2 oz/ac) Medium: 0.29 l/ha (6 oz/ ac) High: 0.73 l/ha (12 oz/ac) |
Experiment III | Evaluate how imazapic applications might interact with spatially segregating NWSG and WF species at planting. | NWSG + WF planted together NWSG + WF planted spatially separate | Control: no imazapic Imazapic: 0.44 l/ha (6 oz/ac) |
Experiment IV | Evaluate 2 glyphosate application treatments and 2 other non-chemical strategies for establishing wildflowers. | Mix of NWSG + WF | Glyphosate Glyphosate and raking of thatch Tillage Prescribed fire |
