Oregon Pesticide Examination: Ornamental and Turf Herbicide Questions and Answers Already Passed

Oregon Pesticide Examination: Ornamental and Turf Herbicide Questions and Answers Already Passed Integrated Pest Management: What is the definition of IPM? Integrated Pest Management Integrated Pest Management: What are some of the advantages of IPM? Regulations, Environment and Economics. Integrated Pest Management: What are some of the control methods under IPM? Prevention, mechanical, cultural and chemical. Integrated Pest Management: What does it mean to be scouting and monitoring under IPM? ID weed the you don't want around and can prevent a pest. Integrated Pest Management: What is the economic threshold? Is the pest population density at which control measures are needed to prevent the pest from reaching the economic injury level. Integrated Pest Management: Define the economic injury level. Economic injury level, is the pest population density that causes losses equal to the cost of control measures. Integrated Pest Management: What are some of the ways we can manage herbicide resistance? Do not use herbicides that are in the same group year after year. Do no use an herbicide from the same group family more than once in three years. Use other methods of weed control along with herbicides. This may include hand pulling, tilling, and mulching. Use other methods of weed control. Rotate among herbicide families. Do not use higher rates. Kill all the targeted weeds if possible. Use herbicide combinations. What are some of the key considerations for controlling broadleaf weeds? Selectivity, preemergence vs postemergence, how long the herbicide is on the foliage, the age and how vigorously the plant is growing and non-pesticide ways of maintaining your plants healthy. What are some of the key considerations for controlling grasses? Annuals grasses: Preemergence herbicides are highly effective, before seed germinated, watering half inch, wait 2 to 4 months before seedling, do not install sod at the same time, mowing 2 or 3 times after applying preemergence herbicides. perennials grasses: Treat the area with non-selective herbicide and throw out whatever we have and start over. What is the life cycle of an annual? Germinate, vegetative, flower. set seed and die. What is the life cycle of an biennial? BIENNIAL plants complete their life cycle within two years. In the first year. the plant forms basal leaves (rosette) and a large root system (taproot). the second year the plant flowers, matures, and dies. What is the life cycle of an perennial? PERENNIALS live more than two years. Some may live almost indefinitely, resprouting from vegetative plan parts. Because of these persistent, resprouting, roots, rhizome, stolons, tubers, and plant fragments, perennials spread rapidly and are difficult to control. Herbicides: Define selectivity as it relates to herbicides. A major advantage of chemical weed control over cultivation is that some herbicides kill only targeted weeds. Herbicides that control weeds while doing little or no damage to desirable
