Each of these multimedia CD programs (digital color images, sound, & video) offers thorough coverage of diseases, herbicide injuries, insects, nutrient deficiencies, and other damaging factors important to corn production in the Midwest. The CDs are powerful diagnostic references and effective teaching resources for crop producers, crop production support professionals, educators, and students. Among the programs' many features is a practice quiz which refines diagnostic skills by randomly presenting diagnostic situations. Another feature is a symptom-driven diagnostic key that aids in the identification of actual crop problems.
