Dear Bob:
It is a pleasure to report to you the total pesticide use
figures for Virginia's Forestry community during 2003. The
figures are compiled by the Forestry Herbicide User Group,
which held its annual meeting on December 2, 2003.
At your request, we have continued to separate the data
between the Chesapeake Bay watershed counties and Non-Bay
watershed counties as shown on the attached map. The final
table shows total statewide use. A quick overview:
1. During 2003, Virginia Forestry treated
61,796 acres using 85,063 pounds of active ingredient.
The attached
graphic shows the trend in forestry herbicide usage
since 1986.
2. A total of 11 active ingredients were used in the 2003
program; the overall average application rate was 1.38 pounds
a.i. per acre. The average lbs. active ingredient per acre
increase in 2003 was due primariliy to an increase in the
heavier site preparation applications as a percentage of
the total acreage, from 13 percent in 2002 to 22 percent
in 2003.
3. Pine release, sod and herbaceous weed control and mid-rotation
applications, which together comprise 78% of program acreage,
had a combined application rate of only 0.78 pounds a.i.
per acre.
4. Glyphosate, imazapyr and hexazinone accounted for 92%
of the total chemical use.
5. Again this year in the acre summaries, we have broken
out mid-rotation application. Mid-rotation refers to pine
stands in the 12 to 25 year old range.
As in the past, we ask that no other data be combined with
those in this report. Members of the Forestry Herbicide
User Group are available for making presentations of this
data should that need arise. Please feel free to contact
me if you have questions.
Finally, I have included a table showing pesticides used
at the VDOF tree nurseries in 2003. This data is not included
in the above statement.
Sincerely,
