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 …
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 …
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.
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.
5.7 Critical Period of Weed Control – Principles of Weed Control
Critical Period of Weed Control is a threshold commonly used, which is relative to time from planting date. Researchers have identified at what point during the growing season weeds can inflict the most …
Determining ETs or action thresholds of weeds involves methods that can measure and predict the level of weed infestation.
Level of threshold weed density does not affect the long-term …
We conclude that the economic underpinning of the threshold concept is deceptive and does not provide a base for rational use of weed control in the long term.
