Virginia Commercial Applicator Category 3B Turf Pest Control Key Terms 100% Correct Calibrate To measure the delivery rate and distribution of application equipment; to adjust application equipment so the desired amount of pesticide is applied evenly to a given area. Disease An abnormal, unhealthy condition. Turf diseases may be caused by abiotic or biotic factors. However, they are typically due to infectious organisms such as bacteria, fungi, and viruses. Exclusion Using some sort of barrier to keep a pest out of an area. Exposure Coming in contact with a pesticide either by ingestion (oral), inhalation, or absorption through the skin (dermal). Habitat A specific area or environment in which an organism normally lives. Insect An arthropod with three body regions: a head (front), a thorax (middle), and an abdomen (rear). Most insects have one pair of antennae on the head, two pairs of Wings, and three pairs of legs on the thorax. Most have complex mouthparts adapted for a special type of feeding. Integrated Pest Management (IPM) VA management system that uses all appropriate pest control strategies to reduce pest populations to an acceptable level. IPM uses an ecological approach to pest management. Life Cycle An 0rganism's progression through developmental stages. As some organisms go through their life cycle, they change in body form and habits. Mite A small arachnid with eight legs in the adult stage. Mites have a single body region, which seems to lack segmentation. Some mites are plant pests. Mollusk A soft-bodied animal. A mollusk does not have a backbone. Mollusks have a hard calcium-based shell covering its body. Clams, snails, and slugs are mollusks. Monitoring The process of assessing-"keeping tabs on"—the size and distribution of a pest population in an area. Natural Controls Natural forces that affect pest populations. Examples include climate, natural enemies, natural barriers, and the availability of food, water, and shelter. These natural forces act independently and may either help or hinder human attempts to control pests. Nematode A small, unsegmented roundworm. Most nematodes are so small that they cannot be seen with the naked eye. Leaching Movement of a substance (such as a pesticide) in solution downward through soil. Nematicide A pesticide that controls nematodes. Parasite An organism that obtains its food from another living thing, and in so doing, harms that organism (its host). The disease organism is the parasite, and the infected organism is the host. Perennial A plant that lives for more than
