Landscape – While the agents are doing their job, previously out-competed native species can gradually recover and recolonize areas without the need for extensive replanting. Safety – Biocontrol agents pose no threat to human health, crop production or beneficial organisms Spread – The control agents, be they insects or pathogens, locate and affect most – if not all – populations of a weed until they’re stopped by physical, environmental or chemical barriers, just as they would in their native range The weed is continually under attack from an army of natural enemies Sustainability – It’s permanent, and therefore completely sustainable.
It also allows the amount of herbicides required for weed control to be reducedĬost – After the initial research costs, once the agents are established and having an impact on the weed the only further expenditure required would be that used for monitoring activities The ability of biocontrol agents to spread and adapt, and their effects on. Environmental – Biological control is natural and doesn’t rely on the use of man-made chemicals that can adversely impact an ecosystem. Conventional wisdom is that high genetic drift and loss of genetic diversity.
