What is IPM?
Integrated Pest Management, or IPM, is a long-standing, sciencebased decision-making process that identifies and reduces risks
from pests and pest management strategies. It coordinates
information on pest biology, the environment, and available
technology to prevent unacceptable levels of pest damage by the
most economical means, while posing the least risk to people,
property, resources, and the environment. IPM provides an
effective strategy for managing pests from developed agricultural,
residential, and public areas to wild lands. IPM provides an
effective, all encompassing, sustainable approach to protect
natural resources, crops, animals and people from pests. IPM
recommendations are frequently recognized as Best Management
Practices (BMP’s) to manage weeds, disease and insects for
production of food and fiber (USDA National Road Map for
Integrated Pest Management).
What is IPM?
IPM is the coordinated use of pest and
environmental information and available pest
control methods to prevent unacceptable levels
of damage by the most economical means with
the least possible hazard to people, property and
the environment. - EPA.

IPM for Potato
Spudman Survey- January 2012
The top three potato varieties:
• Russet Burbank
• Yukon Gold
• Norland
http://spudman.com/downloads/2012_SpudmanSurveyResults.pdf
Our Healthy Grown sustainable
farmers work with ecologists,
conservationists and University of
Wisconsin researchers to utilize and
find better, less-invasive ways to
manage pests and invasive plants.
~and~
Restore natural ecosystems, prevent
erosion, support native plants and
animals, conserve quality water, and
improve potato production.

Detailed Findings 2004
Purchase intent increased when shoppers heard about the
Healthy Grown concept: 81% of consumers indicated they
were more likely to purchase Healthy Grown after hearing it
was certified environmentally-friendly, WWF endorsed and
“good for you and the environment”
When you purchase potatoes, what do you look for in your selection?

6. Insect Management Section
6A. Which of the following practices did you use to manage
insects prior to planting this year’s crop? (check all that apply)
•
Culturally manage a potato insect pest (e.g. wireworm,
European corn borer) in the crop planted prior to potatoes in
this field. = 1 point
•
•
Select resistant or tolerant varieties. = 1 point
•
Avoid using similar chemical control tactics (e.g. systemics)
on fields adjacent to the previous year's potatoes for a
resistance management practice. = 2 points
Avoid planting potatoes on fields adjacent to previous year's
potatoes. = 3 points
6. Insect Management Section
6C. Which of the following practices did you use to manage insects during the
growing season: (check all that apply)
•
•
•
•
•
•
•
•
•
Adjust the planting date of the potatoes on this field in order to avoid insect
problems. = 2 points
Select an insecticide based on preserving natural enemies. = 3 points
Manage the health of the crop to enhance its ability to with stand a degree of
pest pressure. = 1 point
Plant trap crops (e.g. field edges) or use physical barriers (e.g., plastic-lined
trenches) along field borders to slow the migration of Colorado potato beetles
into this field. = 3 points
Use a fall trap crop (e.g. a strip of potatoes that are not vinekilled) to concentrate
beetles for more efficient control of overwintering beetles. = 3 points
Avoid spraying for insects just before vinekill or harvest. = 1 point
Scout potatoes for insect pests at least weekly throughout the growing season in
a systematic pattern. = 2 points
Keep field records on the density of each insect pest for long-term comparisons.
= 2 points
Rotate chemistry families of insecticides specifically to avoid the emergence of
resistance. = 3 point
Pesticide Use Lists
Toxicity Units
Application rate X toxicity value = toxicity units
Toxicity Factors have four components: (1) acute mammalian toxicity, (2) chronic
mammalian toxicity, (3) ecotoxicity, (4) impacts on beneficial organisms.
Total toxicity units = all compounds sprayed during the growing season
Maximum toxicity units:
SS = 800 toxicity units per acre for the season.
LS = 1200 toxicity units per acre for the season.
Potential Threats to IPM
Systems
 Loss of pesticides
 Offshore competition
 Damaging weather
 Population Growth
 Environmentalism
 Government “assistance”
Potential Threats to IPM
Systems

Food borne illnesses
 Land availability and use
 Labor and immigration
 Water quality and quantity
 Higher operating costs (fuel)
 New plant pests and diseases
