The concept of thresholds has many applications in weed science, depending on the response being measured In this article, we will explore the essential principles of threshold concepts in weed science and discuss how they can be applied to improve crop yields. The most common adjectives used to describe thresholds are damage, economic, period, and action.
Weed management threshold is a critical concept in advanced weed science, serving as a guide for determining when weed control measures should be taken to prevent crop yield losses. One key aspect of successful weed management is understanding threshold concepts Economic threshold (et) determines the weed density at which control measures become economically justified
The et is the density of weeds at which the cost of control equals the benefits obtained under particular weed control measure adopted.
