Turf (3b): Turf Pest Management - Test Your Knowledge Questions and Answers. Name some of the factors turfgrass managers must consider when setting pest management priorities. - Answer- Turfgrass management professionals must consider human safety, environmental safety, turf use(s), efficacy, and economics. Why do pest management thresholds in turf vary? - Answer- Pest thresholds vary from site to site because they depend on site characteristics and uses. For example, there may be zero tolerance for pests of any sort on a gold green. On the other hand, there may be no great need to control pests in the grassy areas of an industrial site. However, setting thresholds in some sites - like a school athletic field or playground - may not be simple and clear-cut. A thick, uniform surface is ideal for play areas, for optimum utility and safety. This, in turn, means the tolerance for pests is low. However reliance on pesticide use may not be acceptable for some recreational sites, especially if the primary users of that site are children. What is the first, most basic step to take to manage pest problems? Explain your answer. - Answer- Use Best Management Practices (BMPs) for initial design, installation, and maintenance programs. Begin by selecting high quality, disease- and insect-free turfgrass. When possible, plant or install resistant varieties. Choosing the right variety for the site and use(s) is essential. Next, good cultural practices provide the best conditions for plant health. Why should you focus your attention on key pests, key varieties, or key locations? - Answer- They are most likely to cause problems. Key pests, varieties, and locations require special monitoring and care. What is a "key pest"? - Answer- A key pest is one that often reaches population densities that justify management, and/or is capable of causing unacceptable damage at relatively low densities, and/or attacks and damages turfgrass(es) in conspicuous or valuable areas. What is a "key variety"? - Answer- A "key variety" has a special "high profile" use. A variety that sustains damage from pests on a regular basis, or has a particular pest that can kill or disfigure it in low densities, would also be considered a "key variety." Describe a site that would be considered a key location. - Answer- Key locations are heavily used or are significant in some way. Areas where turfgrasses have chronic problems with pests, and/or areas that are near something or someone requiring special protection are "key locations."

Name several things you need to make an accurate diagnosis of a pest problem. - Answer- Description of the type and extent of plant damage, identification of the pest, familiarity with the life cycle of the pest, a good estimation of the size and distribution of the pest population, and an assessment of whether it is increasing or decreasing.
