[MAIPC] fig buttercup

Isolated specimens can be dug out with a shovel but must be dug deep enough
so the bulbs all come out. Spraying with glyphosate is best done when about
half of the specimens have flowers. Marc

This is a fantastic idea for a biocontrol project.  I'm located at the very
northern reach of Fig Buttercup in New York and I'm trying to get more
surveying done this spring while the opportunity is there.  For folks in
more heavily infested areas, especially at northern latitudes, do you have
advice on the timing for these surveys?  Here in the Capital Region this is
at the moment an ED/RR scenario, it seems that it is more likely to be
located along the Hudson River corridor from the few reports that we do
have.

Dear Robyn,

The Maryland Chapter of the Sierra Club respectfully requests that the
Biological Control Program investigate an effective host specific,
pathogenic biological control of Fig Buttercup (Lesser Celandine)(Ranunculus
ficaria also known as Ficaria verna Huds)  It is our position that this
research has could provide the means to substantially reduce damage,
particularly to threatened species, by this invasive species.

A 2015 weed risk assessment conducted by the Maryland Department of
Agriculture (MDA) describes fig buttercup as a High Risk species and
suggests that the collection of additional information could move the risk
score further into the high risk region. A significant invasive in the
United States, R. ficaria readily spreads in moist sites forming extensive
and dense mats outcompeting plants in natural systems (MDA,  2015. Retrieved
from
<http://mda.maryland.gov/plants-pests/Documents/Ficaria_verna_%20WRA%2006171
5.pdf> http://mda.maryland.gov/plants-pests/Documents/Ficaria_verna_
WRA%20061715.pdf). 

The scope of this research would include first, the investigation of
population controls of native European sites that exhibit typical densities.
Such research would take into account that multiple factors or mechanisms
may in fact keep bulb regeneration in check. Once probable mechanisms were
identified, a protocol would be developed to evaluate artificial treatments,
such as inoculation with one or more pathogens. This preliminary work would
simplify the selection of a U.S. test species and could make more efficient,
the evaluation of risks to non-target North American species. Alternatively,
the same approach could be applied to related, North American species.

Understanding the mission of the Biological Control Program is to "work with
cooperators to import, screen, develop, release, implement, monitor, and
transfer biological control technologies to prevent the establishment, slow
the spread, and manage pests of significant economic, environmental or
regulatory importance." we respectfully request that such an effort begin
for the biological control of Fig Buttercup (Lesser Celandine).
Specifically, we would hope to see the study of entomological and
pathological controls of native populations to learn how spread is
constrained.

We sincerely appreciate your consideration of our request. We have made the
same request to your colleagues at Crop Production and Protection, ARS with
the hope that funding might be more readily secured through a joint request.
