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
Critical Period of Weed Control - UMass Amherst For many disease and insect pests there are well-established thresholds to help determine the most critical management times to avoid yield loss
Economic Threshold Weed Control Farming: Smart Decision Guide Adopting economic threshold weed control farming practices typically reduces herbicide costs while maintaining profitability University research demonstrates that threshold-based programs decrease herbicide applications by 20-40% compared to calendar-based programs
The Threshold Concept and its Application to Weed Science Regardless of the type, thresholds imply that weed effects are population dependent, and as such, allow some type of prediction to be made relative to the consequences of control decisions
Trait-based weed control decisions compared to economic . . . If the threshold value for one of the two weed taxonomic groups is reached, the cost of the possible negative consequences caused by the weed infestation is assumed to exceed the costs of weed control treatments
Economic threshold concept for weed management in crops . . . Economic threshold (ET) determines the weed density at which control measures become economically justified ET is primarily a binary decision-making tool guiding whether to control weeds or not Calculating ET involves complex models, with results varying based on weed species and crop conditions
