GOOD MORNING!
Please get your

SUSTAINABLE AGRICULTURE
HOW WOULD YOU EXPLAIN THE
TERM “SUSTAINABLE”?
FOOD FORWARD! (24MIN)
SO WHAT ABOUT HTOWN?
How do people get to the
sustainable food?

All $ directly to farmer
All local = all seasonal

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

*INTEGRATED PEST MANAGEMENT

Overarching philosophy:

Elimination of pests is not possible, so the goal must
be pest suppression.

General practice: Watch pest populations. When
there are too many, take action. 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

DIVERSITY PROTECTS HARVESTS FROM PESTS
AND DISEASES BECAUSE THEY RUN OUT OF
FOOD.
MONOCULTURES ARE LIKE A BANQUET!
CULTIVATION/PHYSICAL APPROACHES


Crop rotation –
non-legume, legume, fallow field/cover crop
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 rows
provide shelter for
beneficial 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
OTHER PREDATORS
INSECTIVOROUS BIRDS
CHEMICAL PEST CONTROL

Pheromones: used in
bait traps to lure
insects away from
crops
CHEMICAL CONTROL

As a last resort,
IPM farmers will
use pesticides
(herbicides,
insecticides,
rodenticides,
fungicides)
DIRECTIONS: CUT OUT AND GLUE THE IPM
STRATEGIES INTO THE CORRECT COLUMNS
Prevention strategies
Response strategies

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
