An understanding of weed population dynamics may allow the definition of maintenance levels, where a low annual or biennial control commitment would be sufficient to pre-vent substantial population …
(PDF) A Computable Economic Threshold Model for Weeds in Field …
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 uncertainty …
Level of threshold weed density does not affect the long-term …
It is shown that long-term apphcation of thresholds results in a control frequency that is independent of threshold level, and in aperiodic dynamics of the weed population which may cause uncertainty …
(PDF) Revisiting the concept of the critical period of weed control
Jan 10, 2022 · Weeds are a major biotic constraint to the production of crops. Studies on the critical period of weed control (CPWC) consider the yield loss due to the presence of all weeds present in the...
Regardless of the type, thresholds imply that weed effects are population dependent, and as such, allow some type of prediction to be made relative to the consequences of control decisions.
Wheat grain yield and yield components as influenced by different weed species (mean of n = 3 replications; each control replicate taken as the mean of two weed-free control pots)
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 …
