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
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
Level of threshold weed density does not affect the . . . - ScienceDirect Weed control thresholds are often presented as a means to reduce unnecessary control measures, thereby increasing the effectiveness of weed management While the threshold is a useful tool for cost-effective application of control on a single-year base, its role over the longer term is more complicated
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
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
Economic Thresholds and the Case for Longer Term Approaches to . . . There are some theoretical concerns with applying a static approach such as the economic threshold to weed management decision making An improvement is to adopt a population management approach where the intertemporal effects of decisions are taken into account
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
