[Wikipedia] Effects on Hosts: The Japanese dodder is a plant that parasitizes other plants. From mild development issues to serious complications sometimes resulting in death, the Japanese dodder can cause a wide spectrum of effects on its plant host.[4] Farmers in particular can be affected by this plant, as infection leads to less crops they are able to harvest.
