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. To effectively manage weeds and reduce their impact, our scientists undertake research that underpins biological control (biocontrol) programs for the most problematic weeds. Biological control is the practice of managing a weed by the deliberate use of one or more natural enemies (biocontrol agents) that suppress it Following their introduction and establishment, populations of biocontrol agents build up to very high levels due to the abundance of the weed. The following reading analyses the impacts of weed control or the failure to control weeds and shows how these affect producers, other land owners and the public.
