Economic Threshold for Weeds Formula For Calculating Economic Treatment Threshold Steps: D etermine the expected yield level of the crop assuming weed free conditions Enter this figure on line one of the form on the reverse side of this page S urvey the field two weeks after planting and estimate the average number of weeds based on 100 feet of row
The Threshold Concept and its Application to Weed Science 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 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
(PDF) A Computable Economic Threshold Model for Weeds in . . . A model is developed to determine the minimum weed population where a decision to apply a postemergence herbicide would be profitable The economic threshold model accounts for changing economic conditions, the effect of weeds on crop quality, the effect of multiple weed species on yield and quality, and uncertainty about spraying period length
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
Mastering Threshold Concepts in Weed Science 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
A Computable Economic Threshold Model for Weeds in Field . . . Others, mostly agricultural economists, have concentrated on the development of the theoretical threshold model by examining various real-world aspects of the pesticide decision problem Hall and Norgard considered the optimal timing of pesticide applications throughout a season for a single pest A theoretical model that determines both the threshold pest density and the optimal dosage (the M
