(PDF) Level of threshold weed density does not affect the long-term ...
Abstract Weed control thresholds are often presented as a means to reduce unnecessary control measures, thereby increasing the effectiveness of weed management. While the threshold is a useful …
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 …
A paradigm shift from thresholds to longer term population management is warranted and the principles of natural resource economics illustrate that including the intertemporal effects of weeds control will …
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 …
Economic Thresholds and the Case for Longer Term Approaches to ...
Jan 20, 2017 · The principles of natural resource economics illustrate that including the intertemporal effects of weed control will, for a given size of a seed bank, result in a greater level of weed control …
Level of threshold weed density does not affect the long-term …
May 1, 1997 · Abstract Weed control thresholds are often presented as a means to reduce unnecessary control measures, thereby increasing the effectiveness of weed management. While the threshold is …
It is apparent from this equation that any increase in herbicide or application cost will increase economic thresholds, other factors being constant. On the other hand, any increase in crop yield, value, degree …
