Daver, when you choose the spraying option what is protocol? Are you cutting first then spraying, or just applying the chems. Secondly, what chemicals do you use? Thanks
Caveat...I am working from memory here, so take it FWIW.
FYI, I did MCM work in years 1, 3 and 5 of my current contract. My last MCM activity(year 5) was about 3-4 years ago now. Although in theory, each of my three MCM actions should have been identical, there were some variations.
I had enough volunteer trees in the fields that I remember Paul getting his sprayer boogered up as he inevitably ran into some of them. That led to him spot mowing to eliminate the snaggy little trees in various places. Otherwise, we did not mow off the brome prior to spraying. I also did burn a few spots prior to spraying later in the spring too. I kind of made up that hybrid/combo(burn and spray) approach myself.
I believe it was a "1/2 strength" glyphosphate solution that was sprayed. The idea was to kill off some, or even a lot, of the brome...but not to nuke it all. This did work as anticipated and there is now quite a bit more diversity of plant life in what was previously a solid stand of brome.
I will also say that I can tell where the older, years 1 and 3, sprayings were done, as the brome starts to dominate again after a few years of being left alone. So I do some non-prescribed MCM of my own each year too to keep the diversity up and the brome down...and also keep the volunteer trees at bay.
