  • I climbed again in June 2007 and some branches have new HWA but they may not mature this fall. In general, the trees look pretty good, with tree #10 (in first video) having the healthiest and fullest crown. No HWA was observed in that tree in June 2007.

    I plan to return this fall after leaf drop to film and photograph the grove of ten trees from the ridge across the creek and show the striking difference between the results when you act QUICKLY versus wait a few years to treat.

  • the videos were shot on October 2006 and the trees (10 in total) were treated with the highest dosage of imidacloprid 75 WSP in November 2002. They were retreated (against my wishes- ruins the experiment...) in fall 2005.
