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 …
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.
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 Threshold Weed Control Farming: Smart Decision Guide
Nov 15, 2025 · Adopting economic threshold weed control farming practices typically reduces herbicide costs while maintaining profitability. University research demonstrates that threshold-based programs …
14.7 Effects of Weed Densities and Soil Properties
Even with herbicide rates adjusted to compensate for soil properties there is a weed density effect on herbicide activity, with herbicide efficacy (success) decreasing with increasing weed density. The …
Determining ETs or action thresholds of weeds involves methods that can measure and predict the level of weed infestation.
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 …
