1. Control experiments on Japanese knotweed (Oregon)
From: Jonathan Soll (jsoll(at)tnc.org)
I am doing carefully controlled experiments on Japanese knotweed control
in Oregon. So far, I have found that cut-stem treatment with 50%
glyphosate does not work (at least as a single application). This year we
are testing both cut stem (wicking) and spot spray with both glyphosate
and triclopyr (Garlon 3A). One month after a mid-May stem treatment with
Garlon, the plants showed no sign of resprouting. We sprayed some plants
in June after letting them regrow following cutting in May. I will
continue to update results as they occur.
If you asked me today, I would say cut the plants a couple of times during
the growing season then either spray or stem treat with Garlon 3A in the
late summer when they resprout to a height of 0.5 meters.
By the way, we have gotten permission from USFWS and NMFS to use Garlon
along waterways, as long as we are using backpack of smaller pump
sprayers. Garlon 3A is normally not supposed to be used directly over
water (but nearby IS OK), but I believe a newer formulation (Garlon 4a?)
may eventually be registered for such use.
I welcome any and all information on others tales of the devil knotweed.

2. NFWF Grants (Nationwide)
From: Barry Rice (bamrice(at)ucdavis.edu)
The National Fish and Wildlife Foundation (NFWF) is publicizing its
"request for proposals" (RFP). NFWF grants provide matching funds that can
augment your other grants. If you are interested in learning more, go to
the NFWF page on these grants, i.e.:
http://www.nfwf.org/rfp_2001.html
Two relevant grant programs are:
**Native Plant Conservation Initiative: proposal deadline, August 15.
This program supports on-the-ground conservation projects that protect,
enhance, and/or restore native plant communities on public and private
lands.
**Pulling Together Initiative: proposal deadline, 7 November.
The goals of this program are: 1) to prevent, manage, or eradicate
invasive and noxious plants through a coordinated program of
public/private partnerships; and 2) to increase public awareness of the
adverse impacts of invasive and noxious plants.
