Section 2: Principles of Pest Management Flashcards | Quizlet Cultivation is one of the most important methods of controlling weeds Mechanical devices such as plows, disks, mowers, and cultivators physically destroy weeds or control their growth and disrupt soil conditions necessary for the survival of some microorganisms and insects
Mastering Threshold Concepts in Weed Science Action Threshold (AT): The density of weeds at which control measures should be implemented to prevent the weed population from reaching the economic threshold
Bosi Sara: IPM for weed control: the threshold concept - JKI 2023 Set an action threshold, a point at which pest weed populations indicate that pest weed control action must be taken a treatment is “justified” only if the benefits of control is greater than the cost of control
Critical Period of Weed Control - UMass Amherst The Critical Period of Weed Control (point A to point B) is the timeframe within a crop growth cycle, during which weeds need to be controlled in order to maintain crop yields
ESTABLISHING TOLERANCE LEVELS (“ACTION THRESHOLDS”) Tolerance levels or action thresholds can be developed for agricultural crops by studying the effect of an insect or pathogen or weed on the ultimate yield of the crop
Understanding Thresholds: A Guide to Effective Pest Assessments Action Threshold (AT): The AT is similar to ET but serves as an earlier warning signal It indicates the pest population level at which action should be initiated to prevent reaching economic thresholds
