Herbicide Application |
Between November 13-15, 2006 the LTER alleyways were treated herbicide to control broadleaf weeds.
The many weed we were trying to control was dandelion.
Dave Orbeck from KBS grounds department sprayed the LTER alleyways.
He sprayed the alleyways with the Cushman that grounds owned.
I think the only thing sprayed on the alleyways during these dates was 2,4-D ester.
I do not have a spray report for this application. |
