As far as I know, Tolkien never firmly decided what orcs really are. At one point, he imagined they were made from clay, like golems. Then he ,remembered that according to the Bible, God made people from dust and clay and so he changed his min. Later, he wrote that there were female orcs and orcs were born after 'manner of men'. After that, he decided they were corrupted men and elves; whatever that means.
Anyway, if we follow Peter Jacksonβs version, which combines the idea of orcs being corrupted elves who are grown like potatoes, from the ground (an idea stole from Warhammer),then yes, itβs probably acceptable to exterminate aggressive potatoes or fungi.
