Invasive Spotlight: Japanese Dodder

Jun 7, 2018

From the Pest in the Urban Landscape blog • June 6, 2018

 

When people think of parasites, often what comes to mind are blood-sucking insects like bed bugs, head lice, and fleas or other bodily invaders on or in humans and other animals. But plants can have parasites too. Most of us are familiar with mistletoe but there is another parasitic plant you may not have heard about: dodder.

There are several species of dodder native to California but they are not as problematic as a particularly invasive species, Japanese dodder, Cuscuta japonica. This invasive plant pest has thick stems that resemble spaghetti. It grows larger and faster than native dodders and can even cover entire trees or shrubs.

Japanese dodder is spread when pieces of it are broken off and moved about by birds or other animals. It can also be spread through human activities such as pruning, composting, and the improper disposal of infected plant material.

For more information about Japanese dodder and other dodders, consult the Pest Notes: Dodder.
