Mastering Threshold Concepts in Weed Science Threshold concepts are critical in weed science as they help farmers and agronomists determine when weed control measures are necessary The concept of thresholds is based on the idea that there is a certain level of weed infestation beyond which crop yields are significantly impacted
The Threshold Concept and its Application to Weed Science 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 damage, economic, period, and action
Weed control thresholds: a useful concept in natural ecosystems? 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 triggering action on weed control
5. 7 Critical Period of Weed Control – Principles of Weed Control Critical Period of Weed Control is a threshold commonly used, which is relative to time from planting date Researchers have identified at what point during the growing season weeds can inflict the most damage on a crop’s potential yield
Principles of Weed Threshold Research - Cambridge Core Competitive and economic thresholds are distinctive and important concepts to weed scientists The producer is most concerned about the economic threshold because of its importance in production decisions
Weed Thresholds: Theory and Applicability: Journal of Crop Production . . . 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 theory and applicability of thresholds within the context of a systems approach to IWM
