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.

The development of empirical models describing single and multi-species thresholds are reviewed and discussed in terms of the magnitude of weed threshold values in various crops and the …

From our perusal of the relevant literature (e.g. Cousens 1987, Doyle 1991, Norton and Mumford 1993), we conclude that there are four aspects that must be considered in relation to the use …

Simulations suggest optimum weed population levels (thresholds) for maintaining genotypes that are susceptible to control practices and which minimize crop yield reductions.

Abstract. The concept of thresholds has many applications in weed science, depending on the response being measured. The most common adjectives used to describe thresholds are …

Jul 29, 2011 · Weed thresholds are an integral component of an integrated weed management system (IWM). In this paper we review the literature on weed thresholds and examine the …

Nov 15, 2025 · The foundation of economic threshold weed control farming rests on three critical factors: weed density per square foot, expected yield loss percentage, and control cost versus …
