4 IPM/SVP/ICM Program Components A Whole Plant Health Care Plan Cultural Practices site selection site preparation soil management cultivar selection cultural practices canopy management nutrition Disease/Insect Management monitoring/trapping forecasting control choices pesticides/mating disruption Weed Management cultivation cover crops Other Pests - vertebrates birds, deer, racoons

5 The most important thing you can put into the vineyard is your footprints!

6 Proximity to Woods Increased pressure from: Wildlife - habitat Insects - wild vines - habitat Diseases - reduced air movement

7 Bio-Renovation Program Increase organic matter Nutrition Nitrogen and nutrient holding capacity Herbicide efficacy Reduction/elimination of residual herbicides adsorption of herbicides Reduction of plant pathogenic nematodes direct competition vector of virus diseases Control perennial weeds
