Mastering Threshold Concepts in Weed Science Threshold concepts are critical in weed science as they help farmers and agronomists determine when weed control measures are necessary The concept of thresholds is based on the idea that there is a certain level of weed infestation beyond which crop yields are significantly impacted
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
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
Principles of Weed Threshold Research | Weed Technology . . . Competitive and economic thresholds are distinctive and important concepts to weed scientists The producer is most concerned about the economic threshold because of its importance in production decisions
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
