Outcompeting native crops for Area, gentle, moisture and nutrients. Swift development early from the season contributes to dense, tall stands of Himalayan balsam that crowd out other vegetation and cut down species range.
Most of the purely natural enemies, each fungal and arthropod species, gathered and identified in the course of the surveys were being rejected as unsuitable control brokers as they have been in the position to assault other species closely linked to Himalayan balsam.
Satellite infestation – A region of balsam isolated from the broader infestation as a result of early invasion.
