Mastering Threshold Concepts in Weed Science Threshold concepts in weed science refer to the critical levels of weed infestation or density that trigger the need for control measures
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
Critical Period of Weed Control - UMass Amherst The Critical Period of Weed Control (point A to point B) is the timeframe within a crop growth cycle, during which weeds need to be controlled in order to maintain crop yields
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
The Threshold Concept and Its Application to Weed Science Action thresholds may be defined as the weed population at which a grower decides to institute a control tactic, and may be above, below, or at the economic threshold level
Thresholds in IPM - Deciding When Control Is Necessary Thresholds Deciding When Control Is Necessary Establish a threshold at which control measures must be taken In most cases, a certain number of pests are tolerable Generally, when the cost of damage exceeds that of the cost of control it is time to intervene
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
