OOPS!
Our apologies for
errors in the Fall 2010 Tree Talk article "Tree Pests"
regarding chemicals to control Spruce Gall Adelgid. We
went to the archives to get some information that turned out to
be out-of-date and in error. The listed products were
Dursban, Lorsban, Endosulfan and Thiodan. Read on for
correct information.
Distribution of
Chlorpyrifos products (brand names Dursban & Lorsban) labeled
for residential use, including ornamental trees, ceased on
December 31, 2001. It is still used for some agricultural
applications. As part of the voluntary cancellation,
chlorpyrifos containing products were also reclassified as
Restricted Use Pesticides (need an applicator license to
purchase and apply). For more info:
http://www.epa.gov/oppsrrd1/REDs/factsheets/chlorpyrifos_fs.htm.
Endosulfan (brand names Endosulfan, Thiodan) are classified as
Restricted Use Pesticides and are labeled for agricultural use
for commercially grown trees (i.e. nurseries). They are
not labeled for residential use. In addition, they are
currently in a "phase out" stage. Registered use on
commercially grown ornamental trees, shrubs and herbaceous
plants will cease July 31, 2012. ALL uses of endosulfan
will cease on July 31, 2016. For more info:

We
sincerely regret printing information that was misleading.
We hope that you conscientious professional applicators have
been reading the labels carefully before purchase of
application.
The
Fall 2010 newsletters posted on this site have been revised and
contain accurate, more homeowner-friendly, information
(triple-checked!).
Volunteers in Pruning (V.I.P.)
Tree fans are
being sought for a new program designed to improve the future of
young trees in public places. The “Volunteers In Pruning” (V.I.P.)
program trains local tree fans the ins and outs of pruning
recently planted trees for form and structure. They will be
targeting trees that were planted within the last three years.
This is the best time to establish good tree form and correct
any structural problems that can lead to hazards or tree failure
as the trees become older.
The V.I.P.
project is being organized by Community Canopy, a tree care
education program of the cities of Coeur d’Alene, Post Falls,
Hayden, Spokane and the Spokane County Conservation District. These
communities are pooling resources to train volunteers and supply
them with the tools needed to do the pruning. Each community’s
forestry program will choose which public trees will be targeted
for pruning which will be a combination of park trees and street
trees. Those who take care of other trees in public
places, such as church Trustees and Homeowners Association
workers, are also encouraged to attend a training session.
Those
individuals, 16 years of age or older, interested in the V.I.P.
program are encouraged to attend a three hour training session.
Training has already been completed for fall 2010, but if you
are interested please sign up and we can let you know about
future training. The training is free in exchange for
putting in volunteer hours pruning public trees. Because
of limited space, pre-registration is encouraged. Contact
Katie at 208/415-0415 or Garth at 509/535-7274.

Spreading the
Watering Message
During hot summer
months, Community Canopy strives to get the tree care message
out to water newly planted trees. One of these ways we do this
is to display text on local business’ reader boards. See: “HOT
‘N THIRSTY? SO ARE YOUR TREES! WATER DEEPLY DURING OUR HOT, DRY
SUMMERS” running across reader boards throughout the northwest!
Thank you to
generous businesses for doing this pro-bono! Here are a few
locations you can see our message: Trading Company (Post Falls),
Walgreens (Post Falls), Parker Toyota (CDA), North Idaho College
(CDA), North Idaho Fence (Post Falls), and more to come!
Providing
supplemental water to newly planted trees is key to successful
establishment. Community Canopy recommends 5-gallons of water
per inch caliper per week, applied at a slow rate. For more
