WHAT IS IPM?•Decision Making Process
•Integrates all tools available to manage plant or insect problems
•With IPM what you know is more important than which chemical is best
![Page 6: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/6.jpg)
Integrated Pest Management (IPM) is the combining of several tactics – that may include cultural practices, nonchemical methods, as well as pesticides – to manage pests.
IPM – Integrated Pest Management
![Page 7: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/7.jpg)
• There are no pests in a natural ecosystem• We consider certain species pests when they
are where we don’t want them• Pesticides alone will not solve all pest
problems• Not an organic approach but uses all
available options
“Pests” as part of a Natural System
![Page 8: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/8.jpg)
To develop an IPM Plan combine a great deal of information with a strategy that fits the pest and the situation.
Pesticides give quick results – IPM Plan harder to implement, slower to show results, and may cost more initially.
Thresholds and values must be established.
Formulating an IPM Plan
![Page 9: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/9.jpg)
• Monitor pests to determine population or potential infection levels
• Treat when thresholds indicate economic loss
• Suppression – combine pesticides and natural control
• Regulate pest populations with natural ecosystems (recognize & use)
Basic Strategies to Pest Management
![Page 10: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/10.jpg)
1. Diagnose Problems Survey Property Look at all pest problems together
2. Create a Good Offense Deny pests food, shelter, temperature Interrupt their growth or reproduction
3. Keep Plants Healthy Conditions in landscape best for plant growth
IPM Steps to Follow
![Page 11: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/11.jpg)
4. Encourage Natural Enemies Predators or parasites provide partial control
5. Monitor Pests and Plants Systemic check of plant condition – doesn’t happen
overnight
6. Tolerate Injury Threshold of unacceptable damage Plants tolerate a great deal of defoliation
7. Reevaluate the Program Recognize changes as the plant grows and ecosystem
changes
IPM Steps to Follow
![Page 12: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/12.jpg)
Thresholds Defined• Economic.. Damage or potential loss in crop value
exceeds cost of management strategy. (Short and long term)
• Aesthetic.. Replacement value of landscape appearance or utility exceeds cost of management strategy
• Sentimental.. Plant has no economic value but due to historical significance may have sentimental value to property owner.
![Page 13: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/13.jpg)
Why?• Socially accepted movement away from pesticides in landscapes/home gardens
• Government regulations
• Health concerns
![Page 14: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/14.jpg)
Pest Management Strategies• Cultural- Plant choices, mulching, timing of planting, etc
• Biological- Beneficial Insects, Nematodes, Fungi
• Mechanical- Pruning, cultivations, hand removal
• Chemical- Synthetic, organic, and inorganic
![Page 15: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/15.jpg)
Cultural Control• Proper plant selection for micro-environment
• Proper fertilization and liming to avoid over or under feeding.
• Avoid mono-cultures; plant diverse layers of compatible plants
• Plant timing to avoid pest occurrence
![Page 16: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/16.jpg)
Cultural Control
• Proper planting and mulching depth are good ways to reduce both disorders and diseases
![Page 17: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/17.jpg)
Disease Pyramid/Cultural Management
• Understanding the disease pyramid can help with cultural management of pathogens.
• Time is often considered as the fourth component of plant disease development.
![Page 18: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/18.jpg)
Biological Control• Encourage and protect beneficial insects or other organisms (nematodes, mites, birds)
• Releasing beneficial organisms when needed
![Page 19: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/19.jpg)
Mechanical Control
• Hand pulling of weeds
• Cultivation• Hand picking of insects
• Pruning
![Page 20: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/20.jpg)
Mechanical Control
• Trapping• Screening• Temperature modification
![Page 21: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/21.jpg)
• Pesticides are only one strategy of pest management and should be the last resort.
• Used properly they may pose limited or no damage to humans and the environment
• Not the first and only means of control• Include insecticides, fungicides, herbicides,
miticides and nematicides
Chemical Control: Pesticides
![Page 22: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/22.jpg)
• What pests or problems exist?• What is the problem – disease, insect, weed etc?• Is the problem serious enough to use a pesticide?• Can the problem be fixed by cultural change or
does it need corrected?• What is the safest pesticide to use?• When and how much pesticide should be
applied?
Before you apply ask these questions
![Page 23: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/23.jpg)

![Page 46: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/46.jpg)
Protective Clothing (PPE)
Pesticide label will tell you what to wear Body covering – long sleeve shirt,
pants, coveralls, no shorts! Gloves – most exposure is
through hands and forearms Goggles – eyes readily absorb
chemicals Respirator – “Danger or
Warning” Shoes – liquid proof boots or
covers Washing clothes – pre-rinse, use
hot water, not with other clothes
![Page 47: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/47.jpg)
Cost of PPE• When making pesticide choices consider the cost of the PPE
• These costs are including in thresholds• Some PPE may last a year or more $$$• Others may be 1x use but cost $$ per year
• PPE prices change every year
![Page 48: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/48.jpg)
Washing PPE • Pre-rinse clothes worn during applications and wash separate from other clothing
• Wash in hot water then run washer with detergent and hot water w/o clothes
• Line dry• Wash gloves, respirator, boots before storing- soap and hot water!
![Page 49: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/49.jpg)
• Pest incorrectly identified• Incorrect pesticide used• The pesticide improperly used• Pesticide used at the wrong stage of pest’s
lifecycle• Coverage inadequate to control pestime – pest life cycle
Pesticide Failures
![Page 50: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/50.jpg)
Storing Pesticides Properly• Read the label• Store in original container or
label!• Buy only what you need to
avoid long term storage• Away from combustible
materials, food items, fertilizers• Above freezing and away from
extreme heat• Store away from your home(Separate building)
![Page 51: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/51.jpg)
Container Disposal• Triple rinse• Pour rinse in tank, apply
to approved site• Approved disposal site
Buncombe Landfill will take recyclable pesticide containers
• Punch holes in container, before taking to the landfill
![Page 52: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/52.jpg)
Pesticides in the Environment
Moving away from release site may cause environmental contaminationDrift – moved by airVolatilization – liquid to gasSpills, leaks, improper
equipmentHeavy rain may wash awayLeaching – downward
movement
![Page 53: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/53.jpg)
• Vary in the rate they breakdown and how long they stay in the environment
• Most persistent pesticides been removed from the shelves
• Once absorbed broken down into less toxic materials
• Micro organisms break down the pesticide
Pesticide Degradation
![Page 54: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/54.jpg)
Read The Label• Be educated and aware of
what you are doing or recommending with IPM
• Restricted Use Products- (RUPs) only applied by certified/licensed applicators
• Applications of ALL pesticides on the property of another requires a license.
![Page 55: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/55.jpg)
To Recap• Properly identify the problem• Is it abiotic or biotic• If it is biotic is the damage from an insect, disease, mite or animal ?
• Know the history- weather, past applications of fertilizer, pesticides, mulching or pruning practices
![Page 56: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/56.jpg)
Look at SymptomsAbiotic
• Appear suddenly• Affect many plants• Not spreading• Has a defined pattern
• Distinct lines between health and infected tissue
Biotic• Appear gradually• Affect only one
species• Symptoms spread• Occur randomly on
plant or landscape• Halo between healthy
and damaged tissue
![Page 57: Integrated Pest Management and pesticide safety](https://reader035.fdocuments.in/reader035/viewer/2022062503/58ce9afd1a28ab8c3b8b7541/html5/thumbnails/57.jpg)
Causes of Plant Problems• Environmental
(Abiotic)• Temperature (hot,cold)• Light extremes (shade,
sun)• Water / humidity
(flooding, drought drainage)
• Nutrients• Air pollution • Chemical• Physical damage
• Biotic• Animals
•Chewing•Urine
• Insects/mites
• Pathogens•Bacterial•Fungal •Viral•Nematodes
