Euroscope forum. With the widespread and increasing problem of herbicide resistance, growers are forced to change both the short-term and long-term view of weed management. Skipping a spray operation reduces the selection pressure that causes resistant weed populations to develop. The use of economic thresholds can help you combat resistance by managing your herbicide rotation. ABSTRACT The economic threshold (ET) is one of the major decision-making frameworks for rationalizing herbicides use for better weed management while reducing environmental impacts. Jun 12, 2025 · By understanding economic thresholds and applying threshold concepts in weed management, farmers and agronomists can optimize crop yields, reduce unnecessary herbicide applications, and minimize the environmental impact of weed control strategies. Significantly, the debate continues as to the usefulness of the threshold concept in the context of weed management in agricultural sys-tems. Damage threshold is the term used to define the weed population at which a negative crop yield response is detected. As small May 24, 2025 · Recognizing the potential benefits of weeds, it is important to integrate these aspects into weed control decision-making process. Building upon the traditional economic threshold model for insect pests, this paper presents a first step toward upgrading the economic threshold for arable weeds by incorporating biodiversity benefits of weeds. The most common adjectives used to describe thresholds are damage, economic, period, and action. jpci fhw 8uqf ee4o xyizs bohj7 ocpr m4q 2b cnmx
