This material is based upon work
supported by the NH Agricultural
Experiment Station, through joint
funding of the National Institute
of Food and Agriculture, USDA,
under award number 1016530, and
the state of New Hampshire. This
work is also funded by a Northeast
Graduate Student USDA Sustainable
Agriculture Research and Education
grant and a New Hampshire Specialty
Crop Block grant.
Founded in 1887, the NH
Agricultural Experiment Station at
the UNH College of Life Sciences
and Agriculture is UNH's original
research center and an elemental
component of New Hampshire›s
land-grant university heritage and
mission. We steward federal and state
funding, including support from
the USDA National Institute of Food
and Agriculture, to provide unbiased
and objective research concerning
diverse aspects of sustainable
agriculture and foods, aquaculture,
forest management, and related
wildlife, natural resources and rural
community topics. We maintain the
Woodman and Kingman agronomy
and horticultural research farms, the
Macfarlane Research Greenhouses,
the Fairchild Dairy Teaching and
Research Center, and the Organic
Dairy Research Farm. Additional
properties also provide forage, forests
and woodlands in direct support to
research, teaching, and outreach.
The University of New Hampshire
is a flagship research university that
inspires innovation and transforms
lives in our state, nation and world.
More than 16,000 students from all 50
states and 71 countries engage with an
award-winning faculty in top ranked
programs in business, engineering,
law, liberal arts and the sciences
across more than 200 programs of
study. UNH's research portfolio
includes partnerships with NASA,
NOAA, NSF and NIH, receiving more
than $100 million in competitive
external funding every year to further
explore and define the frontiers of
land, sea and space. FGN

To combat apple scab disease,
growers primarily rely on sanitation
and fungicide applications in their
orchards. However, there is increasing
pressure by consumers to decrease
the use of synthetic chemicals due to
concerns of adverse effects on nonpest
species and human health, as well
as the risk of pathogen resistance
development with regular fungicide
applications. Both the potential
decrease in consumer demand and
increased costs of resistant pathogen
management can decrease producer
profits.

University of New Hampshire graduate
student Liza DeGenring is investigating
the development of new tools to manage
apple scab for Northeast farmers.
" Both farmers and apple consumers
would like alternative options for
controlling apple scab. Chitosan has
shown promise in other research
in reducing disease, and there is a
potential to use it to suppress disease in
tree fruit production, " DeGenring said.
According to DeGenring, the
success of sustainable agriculture in
the United States will increasingly
rely on the integration of biologically
based methods with conventional
agricultural practices that rely
on fungicides. The scientific and
agricultural community has begun
to recognize the critical role
microorganisms, such as bacteria and
