3 Essential QuestionWhat is integrated pest management?
4 I P MDefinition: pest management strategy that uses a combination of best management practices (BMP) to reduce pest damage with the least disruption to the environment.Why?Over time pests become resistant. IPM is able to adapt over time
6 IPMTo keep pest populations below the economic or aesthetic injury levelthe point at which plant losses due to the pests are equal to the cost of control.Provide: protection against hazards to humans, domestic animals, plants and the environment.
17 IPM use BMPs Best Management Practices (BMP) practices that combine scientific research with practical knowledge to optimize yields and increase crop quality while maintaining environmental integrity.
18 BMP Help protect sensitive environmental areas. Examples Currently Used:Management of surface/subsurface run offErosion controlb. Cultural control of pestsc. Soil testingd. Timing and placement of fertilizerse. Controlled release fertilizersf. Irrigation managementg. Biological control of pestsh. Pesticide selectioni. Correct pesticide use
19 Basic Elements IPM A. People—system devisers and pest managers B. Knowledge and information needed to devise the system and make sound decisionsC. Program for monitoring the ecosystem elementsD. Pest densities at which control methods are put into actionE. Techniques used to manipulate pest populationsF. Agents and materialsG.

25 Essential QuestionWhat are the major classifications of pesticides?
26 What are the major classifications of pesticides? Pesticides are the materials used to control pests.Pests are anything that causes injury or loss to a plant.natural or man-made.now often done only when absolutely necessary.must be done safely to reduce potential injury to people and the environment.
27 Pests Cause Damage! Damage Plant Parts Compete for space and nutrients WeedsReduced quality of harvested productContaminationDecreased production crop
28 What are the major classifications of pesticides? Insecticides are used to control insects, which are a group of animals with an exoskeleton and three body parts.Killed by body contact, by swallowing, or through the respiratory system.
29 What are the major classifications of pesticides? Miticides are used to control mites and ticks.They are usually killed by coming in contact with the chemical.
30 What are the major classifications of pesticides? Fungicides are used to control fungal disease.Prevent a plant from becoming infected.Applied before the disease is present.
31 What are the major classifications of pesticides? Herbicides are used to kill unwanted plants.Rodenticides kill rodents, such as rats and mice.Usually applied as bait.Eating the chemical poisons the rodents.
32 What are the major classifications of pesticides? Nematocides kill nematodes, which are tiny hair-like roundworms that feed on the roots of plants.Usually applied in the form of a fumigantA substance that produces a smoke, vapor, or gas when applied.
33 What are the major classifications of pesticides? Molluscicides are used to kill slugs and snails.Applied as bait, which attracts the slugs and snails and poisons them.
34 Herbicides Herbicides are classified by selectivitycontact versus translocationtimingmode of action.Herbicides are classified as being selective or nonselective.Selective herbicides act on certain plant species and not others.Nonselective herbicides kill all vegetation.
35 What are the major classifications of herbicides? Herbicides may act on contact with plants or be translocated in the plant.Contact herbicides kill the parts of a plant to which it is applied.Translocated or systemic herbicides are absorbed by the roots or other plant parts and moved throughout the plant by vascular tissues.
36 What are the major types of herbicides? Growth Regulators: kill weeds by altering growth or metabolic processes.Soil sterilant: a compound that prevents the growth of plants in the soil.most commonly used along ditch banks and fence rows.
37 What are the major classifications of herbicides? Timing - stage of the crop or weed development.Preplanting applications are made before the crop is planted to control annual weeds.Preemergence applications are made before the crop or weeds emerge.Postemergence applications are completed after the crop or weeds have emerged.
38 What are the major classifications of herbicides? Mode of action refers to how herbicides kill weeds.The mode of action- the effect on metabolic processes or enzyme systems that result in a lethal or toxic action in the plant.Herbicides may have a single mode of action or a multiple mode of action.
39 What are the major classifications of insecticides? Insecticides are classified by how they enter an insect’s body.Three general groupscontact, stomach, and respiratory.Contact insecticide is absorbed through the skin or exterior of an insect.The chemical must be applied directly on the insect and is normally used with sucking insects.
40 What are the major classifications of insecticides? Stomach insecticide is effective when eaten.Applied to the plant parts, which are eaten by the insect.Most effective on chewing insects.Respiratory insecticide is an insecticide that enters the respiratory system of the insect.It is commonly called a fumigant.Used in enclosed places.

44 Warm UpWhat is this? What do we use it for? Where do you find this?
45 Essential QuestionWhat are the 4 types of exposure to pesticides?
46 Classification of Pesticides Toxicity: degree of poison in a materialAmount of active ingredient and chemical nature determines toxicityClassified into 2 categoriesGeneral UseRestricted Use
47 Measuring Toxicity (oral and dermal) LD50+ LD= Lethal Dose - amount necessary to case death 50= 50% of test animals are killed at that dose Lower the LD50+ the more poisonous the chemical
48 Measuring Toxicity (inhalation) LC50+LC= Lethal ConcentrationMeasured in milligrams per literLower the LC50+ the more dangerous the chemical
49 General Use Pesticides Widely usedJust follow the labelLess harmful to the environmentNo special training required for use
50 Restricted Use Pesticides More toxic than General UseHigh risk to humans and environmentMust have training to use the poison
51 Types of Pesticide Exposure Oral Exposure: Through the mouth or digestive systemWash hands to avoid oral exposure
52 Types of Exposure Dermal Exposure: Through the skin Severity depends on:Toxicity, Absorption rate, Size of exposure area, Length of contact time
53 Types of ExposureInhalation Exposure: Through nose and respiratory systemsBreathing in vapors, sprays, or dust
54 Types of Exposure Eye Exposure: Through the eye Very sensitive Wear eye protection!
55 Be Creative! Draw on your own: Eye Exposure: Eyes are VERY sensitive! Wear protective eyewear !Be Creative!Draw on your own:An advertisement explaining the different exposures and the dangers of pesticide exposure.Individual assignment on a separate piece of paper.Please turn in when finishedOral Exposure:Through the mouth.

88 Integrated Pest Management Managing Environmental Impact of Pesticides
89 Warm Up Projected Pesticide Run Off Where is the highest level of run off? Why is this a major environmental problem?
90 Essential QuestionWhat are the main environmental concerns involved with pesticide use?
91 Pesticides A major concern Problem Areas Nontarget Areas Biodegrading Disposal
92 Non target Areas Area where the pesticide was not intended A result of driftmovement of a pesticide through the airSurface Run offLeaching
93 Biodegrading Ability to be decomposed by biological action Results in accumulation in groundwater, plants or animals (tissues)CollectPesticides with these characteristics should be avoided if possible
94 Disposal Most destructive Easiest to solve! Applicator’s responsibility to make sure pesticides are properly disposed ofWhere do we find this information!?
95 Pesticide Persistence Amount of time it takes for a pesticide to biodegrade or break downMore persistent a pesticide= more likely to enter groundwaterPersistence ClassificationsRapidAccumulativePersistent
96 Rapid Decomposers Break down quickly Remain in target area for short timeLittle adverse effect on environmentWhen used properlyShould be first option to use as a pesticide
97 Accumulative Pesticides Build up in the bodies ofAnimals, HumansPotentially can build to a dangerous levelHarms the organismHarms the consumer of that organism
98 Persistent Pesticides Break down slowlyDesirable for long term pest managementDo not react to light, heat, or oxygenSlightly water-solubleDo not always accumulateIn organisms
99 Disposal Quick and proper disposal is a MUST Resource Conservation and Recovery Act (RCRA)for the management of hazardous toxic materials and their containersillegal to store or dispose of pesticides in ways that would likely harm humans or the environment
100 Disposal ProceduresBased on amounts of pesticides needing to be disposedSmall amounts: like those found in houses, buried in state-approved landfillsLarge amounts: considered hazardous waste, disposed by licensed facilities
101 Triple Rinse Method Recommended procedure as follows 1. Drain the container into the spray tank. Hold container upside down for30 seconds.2. Add water until the container is about ¼ full then close3. Shake or roll the container to rinse all interior areas; then drain the remaining liquid4. Repeat the rinse and drain procedure two more times.5. Puncture plastic or metal triple-rinsed containers to prevent reuse.6. Crush the container to reduce volume.
