Economic Threshold Weed Control Farming: Smart Decision Guide The foundation of economic threshold weed control farming rests on three critical factors: weed density per square foot, expected yield loss percentage, and control cost versus crop value
Principles of Weed Threshold Research | Weed Technology . . . The three additive research techniques to determine competitive weed thresholds are removal or plant-back, paired plot, and area of influence Each method has advantages and disadvantages and must be conducted in a specific manner in the field
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
(PDF) Lecture 4. Crop-weed competition - ResearchGate An example calculation for determining the two weed thresholds is illustrated with common cocklebur in soybeans Generally, the economic threshold is one-half to one-third the competitive
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
Weed Thresholds - dr. lib. iastate. edu One of the keys to successful implementation of this new system of weed control lies in the ability of growers to determine when weed populations exceed economic threshold levels, thus requiring treatment
