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 …
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.
How Does Weed Density Impact Herbicide Efficacy - YouTube
Mar 10, 2021 · Abstract: There are multiple factors affecting a foliar herbicide application and one of them is weed density. Higher weed densities make postemergence herbicide failure more …
The increase in size and density of populations of invasive species with the progressive invasion of natural ecosys-tems means that weed control effort and cost will increase with delays in …
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 …
Economic Threshold Weed Control Farming: Smart Decision Guide
Nov 15, 2025 · Economic threshold weed control farming helps farmers determine when weed populations justify control costs by evaluating weed density, expected yield loss, and treatment …
(PDF) Level of threshold weed density does not affect the long …
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.
