  • Mastering Threshold Concepts in Weed Science
    Minimize the environmental impact of weed control strategies Improve crop yields and quality Understanding Economic Thresholds Economic thresholds are a critical component of threshold concepts in weed science Understanding economic thresholds is essential for making informed decisions about when to implement weed control measures
  • 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 Damage threshold is the term used to define the weed population at which a negative crop yield response is detected An economic threshold is the weed population at which the cost of control
  • Economic threshold concept for weed management in crops . . .
    Abstract and Figures The economic threshold (ET) is one of the major decision-making frameworks for rationalizing herbicides use for better weed management while reducing environmental impacts
  • Weed Thresholds: The Space Component and Considerations for . . .
    The threshold concept was first used by entomolo- considered in determining weed thresholds The eco- gists to improve insect management decisions and nomic has optimum threshold (EOT)4, defined by Cousens become a fundamental principle of integrated pest man- (9), accounts for weed population dynamics and fman- agement (15, 22, 25, 27)
  • 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 As a case study, a small plot located in a typical corn field in central Spain was used, constructing very precise
  • Economic Threshold Weed Control Farming: Smart Decision Guide
    Quick Takeaway Economic threshold weed control farming helps farmers determine when weed populations justify control costs by evaluating weed density, expected yield loss, and treatment expenses This science-based approach typically reduces herbicide costs 15-30% while maintaining profitability through strategic timing and targeted applications
  • Critical Period of Weed Control - UMass Amherst
    Critical Period of Weed ControlFor many disease and insect pests there are well-established thresholds to help determine the most critical management times to avoid yield loss These thresholds are the backbone of an Integrated Pest Management program, helping growers reduce pesticide applications or other pest management practices by only managing pests when economically necessary
