More Analysis on Plateau and WSG plantings
PD & LM,
Here are some interesting tidbits after further analysis on Plateau Label.
Assume my WSG planting is Big Blue, Little Blue, Indian Grass, Switch, and Western Wheat (which most all my CRP is as prescribed by NRCS).
Foxtail - will control it is applied pre-emergement and post emergent if applied before plant gets beyond 4-6 inches ('ve witnessed this in my new FWP planting. Foxtail has come where herbicide not applied. Milestone did not work on foxtail)
Sandbur - Will supress it pre-emerge and will control it post-emerge
Cheatgrass - Control pre-emerge but no control post emerge (interesting, I applied roundup/plateau post emerge and got control in one plot so maybe it was the roundup that did the job)
Big Blue, little blue and Indian - No problems applying to new or established seeding at 2-12 OZ per acre. (i.e. very tolerant).
Switchgrass - If you have this grass planted in your stand you should not use anymore than 2-4 OZ per acre or you run risk of suppressing or losing that species. Not as much of issues is switch is planted in blended stand.
Western Wheatgrass - A little more tolerant than switch grass. Specifies not to apply pre-emergent but can apply post emerge 2-12 OZ/acre.
Summary - Seems like a person could apply 4OZ/acre first year but may injure the Western wheat. Another strategy would be to go wth 4OZ/acre 2nd year but would not work on cheatgrass unless applied with roundup (must apply while WSG's are dormant). Looks like Western Wheatgrass is only cool season in mix so roundup application inMay could wipe this out. Maybe best to not include with WSG from a stand management perspective.
Please chime in with other info, observations, expereince and findings. This will be a good reference for me and others in future.
