Mastering Threshold Concepts in Weed Science 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 Threshold concepts are critical in weed science as they help farmers and agronomists determine when weed control measures are necessary
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
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
Weed Decision Threshold as a Key Factor for Herbicide . . . The objective of this research was to explore the influence that weed decision threshold (DT; expressed as plants m 2), weed spatial distribution patterns, and spatial resolution of sampling have on potential reduction in herbicide use under site-specific weed management
Weed Thresholds - dr. lib. iastate. edu One of the keys to successful implementation of this new system of weed control lies in the ability of growers to determine when weed populations exceed economic threshold levels, thus requiring treatment
Economic Threshold Weed Control Farming: Smart Decision Guide 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 crop value
Weed Thresholds: Theory and Applicability: Journal of Crop . . . 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 importance and limitations of the parameters used to calculate these values
