    1. Host Plant Resistance and Conservation of Genetic Resources

    2. Crop Cultivars Improved agronomic characters (yield, durability, timing and uniformity of harvest) Resistance to pests and diseases (resistant cultivars available in many plant species vs many different kinds of plant pests)

    3. Adaptations of Pests Overcoming Resistance To pesticides (many examples with insects) To resistant cultivars To cultural/agronomic practices

    4. Resistance Management Important so pests dont overcome resistance Important to minimize selection pressure to slow development of resistant pests Use IPM, reduced dosages, rotation of methods, different cultivars, etc. Avoid overusing same method or cultivar

    5. Soybean Cultivars and Resistance to Nematodes
