- 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
- Mastering Threshold Concepts in Weed Science
Mastering threshold concepts in weed science is essential for effective weed management 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
- 5. 7 Critical Period of Weed Control – Principles of Weed Control
5 7 Critical Period of Weed Control Vince describes the idea of different thresholds, where some crops are able to tolerate more of one weed than another These thresholds come into play when a farmer is determining whether or not to apply additional weed control measures (and thereby, extra expenses) – weighing the benefits and the disadvantages Is it more cost effective to spray or is the
- Level of threshold weed density does not affect the long-term . . .
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
- 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
- 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 One successful approach to the implementation of thresholds has been through the development of computerized decision-aid software
- 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
