We are approaching our 1 year anniversary of converting bent to Mini Verde. We did not fumigate, so we are dealing with lingering 419 encroachment and some possible contamination. We were aggressive treating around the edges and known contamination spots prior to planting, but what's weird is it seems worse in the ultradwarf compared to the bentgrass. I can only think of 2 things that are different now as far as soil chemistry goes:
No more pre-emergent applications &
Soil pH is lower now... 6.0-6.5 compared to 7+ before the grow-in.
But I digress...
Anyway, we've spent significant man-hours removing 419 plants with very limited success so far. I have come to the same conclusion that spraying it out may be the most viable option. What about a wicking applicator or sponge on the tip of a backpack sprayer wand? I have a wicking rope, but would be like something smaller and more compact for precise placement. Something like the weed wand from Standard, but in the form of a sponge paintbrush. The weed wand was great for dabbing poa, but not exactly effiecient for bermuda patches. Maybe a paintbrush and a steady hand?? Thinking out loud here, but hoping someone may have a better idea...
