  3. Watch out for Charged Words! Natural Synthetic Organic Chemical Biological Genetic Engineered Risk Safe Carcinogen Toxic Toxic

  4. The Numbers Games Measuring increases and decreases: Ex: 1 in 1,000,000 versus 2 in 1,000,000 “the incidence doubled” “the rate increased by 100%” “twice as many …..” Yet: 2 in 1,000,000 versus 1 in 1,000,000 “the rate decreased by 50%” “half as many …..”

  5. The Numbers Games Comparing Studies with Unequal Numbers: • Ex: • 12 of 400 wells in 1992 had pesticides. • 10 of 100 wells in 1995 had pesticides. • Therefore: • 3% of wells in 1992 were “contaminated” • while • 10% of wells in 1995 were “contaminated” • Newspaper headline: OVER A 300% INCREASE!

  6. Common Misconceptions (in my view) Pastoral View – “Older, simpler ways of life were better than today’s” Organic View – “Natural and/or organic products and materials are safer than synthetic.” No Risk in Banning Pesticides View – “There are no real risks in banning pesticides.” or “Life would be better without pesticides.”

  7. What is Integrated Pest Management ? • A training program that is able to identify pest issues and understanding the best method to control the pest. Chemical Cultural Biological

  8. Healthy Plants Friable soils Proper nutrient balance Proper soil pH – acid vs. alkaline Proper root and crown spacing Ample soil moisture Proper soil temperature Proper light levels Pure air Free of insects and diseases

  9. Do You Understand Soils ? They are not independent – they interact to affect soil characteristics Biological microbes Physical tilth,texture drainage Chemical fertilizer lime

  10. Roots absorb nutrients as water carries it to them

  11. Rate at Which Water Moves in the Soil Soil Types Infiltration rates (inches/hour) Sand >0.8 Sandy &silty soils 0.4 to 0.8 Loams 0.2 to 0.4 Clay soils 0.04 to 0.2

  12. Key Plants - plants prone to damaging pest problems. Key Pests - pests that can cause serious damage or plant loss. Be sure to keep good records ( weather, pests, soil test, fertilizer use, pesticide use, water quality and application)

  13. Monitoring (sampling) of the pest is constantly needed. No single pest control method will be successful. Mere presence of a pest is no reason to justify action.

  14. Why Scouts will Fail • Manager” has little or no ornamental maintenance training and insufficient time and personnel to maintain ornamnetals. • Soil compaction, poor drainage, low fertility and poor organic matter. • Record Keeping - Who will keep the records?

  15. Growing Degree Days (GDD) • A GDD is the measurement of the growth and development of plants and insects during the growing season and its direct relationship to the maximum and minimum temperatures

  16. Enter your zip code and obtain a daily calendar of all the phenological events occurring in your area. Please enter your 5-digit Ohio zip code and a date and the cumulative GDD for that date will be calculated. Zip Code:        Date: Development of this website was funded by the USDA CSREES through the North Central IPM Grants Program. Phenological data was obtained from research by Dan Herms & John Cardina, and web site development was managed by David Lohnes.
