Inadequate scouting frequency or poor sampling techniques lead to inaccurate threshold assessments. Threshold concepts are critical in weed science as they help farmers and agronomists determine when weed control measures are necessary The concept of thresholds is based on the idea that there is a certain level of weed infestation beyond which crop yields are significantly impacted. The concept of thresholds has many applications in weed science, depending on the response being measured The most common adjectives used to describe thresholds are damage, economic, period, and action. To build a successful weed management plan, you’ll need to identify weed species and populations, determine weeds’ economic thresholds, and choose the most appropriate control methods and timing.
Determining ets or action thresholds of weeds involves methods that can measure and predict the level of weed infestation.
