Summary The threshold concept has received con-siderable attention in relation to the management of well-established weeds and other pests in agricultural systems, but its applicability to the …
(PDF) 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.
As an extension of weed threshold models in which crop losses are based on weed density, an altemative model for grass weeds in cereal crops is proposed that incorporates the theoretical …
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 …
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 …
Level of threshold weed density does not affect the long-term …
Modelling studies were carried out to analyse spatio-temporal dynamics of annual weed populations and to identify the key factors that determine the long-term herbicide use of weed control…
The objective of this research was to explore the influence that weed decision threshold (DT; expressed as plants m 2), weed spatial distribution patterns, and spatial resolution of sampling have on potential …
