Economic impact of Arceuthobium americanum
A survey was carried out in Manitoba, Canada, to assess the economic impact of Arceuthobium americanum (EPPO A1 pest) infestations in mature jack pine forests (Pinus banksiana). The area surveyed totalled 140 000 ha of which 12 000 ha or approximately 9% were infested by the dwarf mistletoes. The volume reduction caused by dwarf mistletoe represented 4-8% of the merchantable volume of the surveyed area.
