2A brief history of organic agriculture in the US.
- The word organic originated in Europe, where it
was used to designate a type of farming that
depended on organic matter (not organic
chemistry). - Organic farming has been practiced however for
about 10,000 years, since humans
beganintentionally planting crops.

continued.
- J.I. Rodale admired many historical writers
including Sir Albert Howard (An Agricultural
Testament about farming techniques in India),
and F.H. King (Farmers of Forty Centuries about
agriculture in China). - Lady Eve Balfour, of England, founder of the UK
Soil Association, first used the term organic
gardening.

continued.
- J.I. Rodale brought the word organic to the U.S.
when he began publishing Organic Farming and
Gardening in 1942. He originally financed the
publication with profits from his plumbing and
electrical supply business. - Later his son Bob Rodale took over the family
publishing business, and started
the Rodale Institute to conduct research on
these methods.
5A brief history of non-organic agriculture in the
US.
- Fertilizer products were being tested and used on
a limited basis in Europe (Rothamsted) and the
U.S. in the late 1800s. - Toxic compounds were used to control insects on
fruits and vegetables in the late 1800s and
early 1900s, including arsenic (Paris green). - Solutions including copper and sulfur were used
as fungicides on fruit crops like grapes. Some
of these are still allowed in organic production.
6A brief history of non-organic agriculture in the
US. continued
- Post WWII chemicals used in agriculture included
insecticides originally developed as nerve toxins
(organophosphates), herbicides such as 2,4-D, and
nitrogen fertilizers including anhydrous ammonia
(used to solidify soil to create air strips). - These and other synthetic compounds are not
allowed in US organic standards.
7Those flower children
- The recognition that chemicals such as DDT may
cause significant harm to non-target organisms
became public knowledge with publication of
Silent Spring by Rachel Carson, in 1962. - The birth of alternative agriculture began soon
after, and continued into the 1970s, when it
began to be called sustainable agriculture.
8The O word
- At first, the word organic designated a
particular type of alternative agriculture, with
no legal definition. - The 1990 US Farm Bill established a National
Organic Standards Board to develop official US
standards. - Preliminary guidelines released in 1998. A
record number of comments to USDA required
re-writing some sections. - Final standards released Dec. 2000, and came into
effect in February, 2001. USDA provides
accreditation to private and state certification
organizations.
9Results since then..
- Currently 120 organizations are accredited to
certify, and approx. 10,000 organic farms. - Continued expansion of organic markets (20
annual growth rate for over 10 years). More than
half of consumers report purchasing organic
foods. - Continued expansion of acres under organic
production. - Trend for more large organic farms, some small
farms dropping out (of certification programs)
10 Some of the rules.
- Small farms may use the word organic IF they
sell less than 5000 of organically produced
products. - If larger than that, must certify, or be subject
to 10,000 fine. - Processors must also certify, and follow strict
labeling guidelines. (e.g. made with
organic.etc.). - Many certification organizations also attempting
to meet IFOAM (international) certification
standards as well.
11Other new trends
- More emphasis on locally grown, and knowing the
person who grows your food. - New labeling ideas on a trial basis
participatory certification and pledges, as
an alternative to certification. Still use the
USDA organic guidelines. - New local marketing arrangements CSAs
(community supported agriculture), in addition to
growth of farmers markets, and sales to local
restaurants, schools, BBs, etc.
12And this is important because.?????
- To become an informed consumer.
- If you are a gardener who sells occasional
products (flowers, herbs, vegetables) locally. - If you are considering a larger scale production
operation.
13For certification, one must
- Have excellent farm records. Apply for
certification, participate in annual inspection,
and meet all requirements. - Not use prohibited products/substances.
- Include set-back zones to avoid potential drift
problems, including pollen drift. - Have a soil improvement plan and practices (cover
crops, compost, etc.) - Livestock must have access to fresh air,
outdoors, 100 organic feed, and no prohibited
medications on those sold as organic.
14Soil improving practices include
- Crop rotation
- Cover crops legumes and/or grasses.
- Soil amendments such as composts and/or manures.
- Mulches
- Reduced tillage
- Soil is the mother of all things
- Chinese proverb
15Pest Control Possibilities
- Systems Approach passive
- Systems Approach moderate
- Systems Approach active
- Note none of these is a business as usual but
do nothing approach. Also, they all incorporate
aspects of Integrated Pest Management IPM.
16Pest Control Possibilities- Weeds
- Systems Approach passive
- - high planting density, leafy crops to shade
weeds, targeted irrigation, rotation - Systems Approach moderate
- -pre-plant tillage, lots of mulch, landscape
fabric, hand weeding - Systems Approach active
- - corn gluten pre-emergence, flame weeding,
between row cultivation, soaps as post-emergence,
livestock grazing
17Pest Control Possibilities Insects
- Systems Approach passive
- - resistant/tolerant crops, attract beneficial
insects to area - Systems Approach moderate
- - row cover/barrier, clay film barrier,
diatomaceous earth, vacuum or hand pick, sticky
traps, pheremones (distruptants and traps). - Systems Approach active
- - botanical pesticides (pyrethrum, sabadilla,
neem, rotenone), microbial pesticides (Nolo bait
for grasshoppers, Bt for various larvae.
18Pest Control Possibilities Diseases
- Systems Approach passive
- - grow species that arent affected in our
climate, live with it, rotation, compost and soil
improvement for root diseases. - Systems Approach moderate
- - sanitation (residue management, pruning),
choose specific varieties for disease resistance,
disease free seeds and plants. - Systems Approach active
- - sulfur, horticultural oils, baking soda
(sodium bicarbonate), potassium bicarbonate,
compost tea foliar spray (still experimental, E.
coli concerns?).
19Pest Control As Integrated Systems
- Plan ahead, anticipate, take a design approach to
your garden. - Prevent as many problems as possible, build
resilience into the system. - Monitor plants and pests on a regular basis.
Problems that are identified early are easier to
solve. - Use least toxic methods first, to preserve the
beneficial insects and microbes as much as
possible, and maintain system integrity.
20This is not a systems approach.

27Bins can be used for worm composting. Compost can
be either active or static pile. Use screens to
get quality material.
28Comfrey, a perennial herb, can be composted into
a tea to be used later as fertilizer.
29Good cover crops for the garden
White clover
Yellow-blossom (biennial) sweet clover
Hairy vetch, Lana vetch, and Purple vetch
Crimson clover

32Derived from Kaolin clay, a natural mineral,
forms a barrier film that acts as a broad
spectrum crop protectant. It works to control
insect pests and disease, protect against sunburn
and heat stress. Applied as a water-based slurry
before pests arrive.
Examples of physical pesticides.
D.E. is the fossilized shells of tiny
water-dwelling organisms called diatoms, with
microscopically fine, sharp edges which break the
outer protective layer of the insect and
desiccate them. Applied as a dust or mixed into a
slurry for foliar spraying. Barrier to crawling
pests and soft bodied insects, used in the garden
and as a stored grain additive. Can be used as a
dust on manure for fly control and for intestinal
parasite control.
33Other barrier methods can protect crops from
insects, and provide early season growth
enhancement, and some frost protection.
34Winter is for planning. These are thought
intensive methods.
