10 Integrated Pest Management

  1. 1. Integrated Pest Management
  2. 2. What is IPM <ul><li>Uses a combination of Best management Practices </li></ul><ul><li>Reduce pest damage </li></ul><ul><li>Least disruption to the environment </li></ul><ul><li>Keep pest populations below the economic or aesthetic injury level </li></ul><ul><li>Protect humans, animals, plants & the environment </li></ul>
  3. 3. Phases of IPM <ul><li>Phase I - Action threshold is the predetermined level when pest control is needed </li></ul><ul><ul><li>The losses due to pests are equal to the cost of control </li></ul></ul><ul><li>Phase II – Evaluate possible control measures </li></ul><ul><ul><li>Chemical </li></ul></ul><ul><ul><li>Biological </li></ul></ul><ul><ul><li>Mechanical </li></ul></ul>
  4. 4. Best Management Practices <ul><li>Combine scientific research with practical knowledge </li></ul><ul><li>Optimize yields and increase quality </li></ul><ul><li>Maintain environmental integrity </li></ul><ul><li>Eliminate the risk of unwanted materials having a negative affect on the environment </li></ul>
  5. 5. Examples of BMPs <ul><li>To Manage surface and subsurface water runoff </li></ul><ul><ul><li>Erosion control </li></ul></ul><ul><ul><li>Soil testing </li></ul></ul><ul><ul><li>Timing & placement of fertilizers </li></ul></ul><ul><ul><li>Irrigation management </li></ul></ul><ul><ul><li>Cultural control of pests </li></ul></ul><ul><ul><li>Etc… </li></ul></ul>
  6. 6. What is a Pesticide? <ul><li>Any material used to control pests. </li></ul><ul><li>Man made or natural </li></ul><ul><li>Classified by the insect they control </li></ul>
  7. 7. Types of Pesticides Bait – attracts & poisons them Snails and slugs Molluscicides Plants Herbicides Preventative Fungal disease Fungicides Contact Mites & ticks Miticides Body contact or or swallowing the insecticide Insect Insecticide
  8. 8. Classification of Herbicides (5.2) <ul><li>Selective herbicide – kills only certain plant species and not others </li></ul><ul><li>Non-selective herbicide kills all plants </li></ul><ul><li>Contact herbicide – kills by exposure </li></ul><ul><li>Growth regulators – kills by altering growth or metabolic processes </li></ul><ul><ul><li>Roots, stems or leaves absorb the chemical </li></ul></ul><ul><ul><li>May take a week or more </li></ul></ul><ul><li>Soil sterilant – prevents the growth of plants in the soil </li></ul>
  9. 9. Classification of Insecticides <ul><li>Contact </li></ul><ul><ul><li>absorbed through the skin or exterior of an insect </li></ul></ul><ul><ul><li>Chemical must be applied directly on the insect </li></ul></ul><ul><ul><li>Normally used with sucking insects </li></ul></ul><ul><li>Stomach </li></ul><ul><ul><li>Affective when eaten </li></ul></ul><ul><ul><li>Applied to the plant </li></ul></ul><ul><ul><li>Affective on chewing insects </li></ul></ul><ul><li>Respiratory </li></ul><ul><ul><li>Fumigants, used in enclosed places </li></ul></ul>

  12. 12. <ul><li>Inhalation Exposure </li></ul><ul><ul><li>Through the nose and respiratory system </li></ul></ul><ul><ul><li>Can be more dangerous than oral or dermal due to the uptake of blood via the lungs and other membranes </li></ul></ul><ul><li>Eye exposure </li></ul><ul><ul><li>Eyes are very sensitive to most pesticide materials </li></ul></ul>
  13. 13. How is Toxicity Measured <ul><li>LD 50 </li></ul><ul><ul><li>Lethal dose – amount to cause death </li></ul></ul><ul><ul><li>50 means 50 percent of the test animals are killed at this dose </li></ul></ul><ul><ul><li>The lower the number the more poisonous it is </li></ul></ul><ul><ul><li>Values given in milligrams of substance per kilogram of test animal body weight </li></ul></ul><ul><ul><li>Equal to parts per million </li></ul></ul>
  14. 14. Inhalation toxicity <ul><li>LC 50 </li></ul><ul><ul><li>LC – lethal concentration </li></ul></ul><ul><ul><li>Measured in milligrams per liter </li></ul></ul><ul><ul><li>Lower the number the more poisonous </li></ul></ul>
