  1. Level of threshold weed density does not affect the long-term …

    May 1, 1997 · It is shown that long-term application of thresholds results in a control frequency that is independent of threshold level, and in aperiodic dynamics of the weed population which may cause …

  2. Weed Thresholds: The Space Component and Considerations for …

    Simulations suggest optimum weed population levels (thresholds) for maintaining genotypes that are susceptible to control practices and which minimize crop yield reductions.

  3. Damage threshold is the term used to define the weed population at which a negative crop yield response is detected. An economic threshold is the weed population at which the cost of control is …

  4. However, because most weed populations generate effects that carry over to following years, an eco-nomically-defined action threshold that deals solely with impact in the current sea-son is not suited to …

  5. Determining ETs or action thresholds of weeds involves methods that can measure and predict the level of weed infestation.

  6. Mastering Threshold Concepts in Weed Science

    Jun 12, 2025 · Threshold concepts in weed science refer to the critical levels of weed infestation or density that trigger the need for control measures.

  7. (PDF) Economic threshold concept for weed management in crops ...

    Dec 26, 2020 · Economic threshold (ET) determines the weed density at which control measures become economically justified. ET is primarily a binary decision-making tool guiding whether to …
