EATING LOCALLY = EATING SEASONALLY
Most plants grow, produce food and then die at certain times of the year.

ORGANIC FOODS PRODUCTION ACT ORGANIC FOODS PRODUCTION ACT 19901990 No inorganic fertilizers or pesticides No use of Genetically Modified Organisms No use of sewage sludge No irradiation (kills bacteria on harvested
food) No antibiotics or growth hormones

ORGANIC ADVANTAGES
Healthier for farmers, consumers Safer for wildlife Doesn’t require as much fossil fuel for
fertilizer/pesticides Encourages companies to pursue more
sustainable practices Legal definition creates reliable label (unlike
“natural”)

ORGANIC DISADVANTAGES
Cost (short shelf life means more potential waste, so more must be sold to break even)
Can be highly processed

THE QUESTION OF ACCESS AND EQUITY 3,200 farmer’s
markets now take SNAP! (suplemental nutrition assistance program)
Farmer’s market food costs reflect a real wage for the farmer

A SPECTRUM OF CHOICES – ALL GROWERS DEAL WITH PESTS!

INTEGRATED PEST MANAGEMENT
Overarching philosophy: Eradication of pests is not possible, so the goal
must be pest suppression.
General practice: Monitor pest populations. When damage of crops will cost more than the cost of action, IPM managers take steps to control pests. Pesticides will be used only as a last resort.

GUIDING PRINCIPLE: PESTS AND DISEASES GENERALLY ARE PLANT-SPECIFIC. Examples –
Boll weevil attacks cotton plants
Rust and smut fungus attack corn
Yellow rust fungus attacks wheat
![Page 30: G OOD MORNING ! Please get out your sustainable agriculture notes from last Tuesday and the hand out “A Healthy Food System Defined” Please read the board!](https://reader036.fdocuments.us/reader036/viewer/2022062309/56649d135503460f949e6d5c/html5/thumbnails/30.jpg)
DIVERSITY PROTECTS HARVESTS FROM PESTS AND DISEASES BECAUSE THEY RUN OUT OF FOOD.

CULTIVATION/PHYSICAL APPROACHES Crop rotation – non-legume, legume, fallow field/cover crop
![Page 33: G OOD MORNING ! Please get out your sustainable agriculture notes from last Tuesday and the hand out “A Healthy Food System Defined” Please read the board!](https://reader036.fdocuments.us/reader036/viewer/2022062309/56649d135503460f949e6d5c/html5/thumbnails/33.jpg)
EACH CROP DEMANDS A DIFFERENT MIX OF SOIL NUTRIENTS
Root/fruit/flowers: high Phosphorous demand (nucleic acids)
Leaves: Nitrogen (photosynthesis proteins)

CULTIVATION/PHYSICAL APPROACHES
Hedge rowsprovide shelter forbeneficial insects,
insectivorous birds and other pest predators (preying mantis, ladybugs, bats)

BIOLOGICAL PEST CONTROL
Release beneficial insects purchased in quantity (pest
predators), encourage
insectivorous birds

CHEMICAL PEST CONTROL Pheromones: used in
bait traps to lure insects away from crops
![Page 40: G OOD MORNING ! Please get out your sustainable agriculture notes from last Tuesday and the hand out “A Healthy Food System Defined” Please read the board!](https://reader036.fdocuments.us/reader036/viewer/2022062309/56649d135503460f949e6d5c/html5/thumbnails/40.jpg)
CHEMICAL CONTROL As a last resort,
IPM farmers will use pesticides (herbicides, insecticides, rodenticides, fungicides)
Find your definition of Organic Food. Put a star next to the IPM practices that an organic farmer COULD use legally.

PRACTICE – WHICH IS MORE SUSTAINABLE AND WHY?
Potatoes bought at the grocery store vs. potatoes bought at a farmer’s market.
Homemade french fries vs. fast food french fries
Inorganic pesticide vs. crop rotation
