Adopting economic threshold weed control farming practices typically reduces herbicide costs while maintaining profitability Soil seedbank dynamics, which are a legacy of previous weed control efficacy, complicate threshold development This becomes even more complicated since seed from different weed species survive and germinate in different environmental conditions. A university of missouri study sheds some light on how management techniques affect weed density 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.
Determining ets or action thresholds of weeds involves methods that can measure and predict the level of weed infestation.
