Peppervine

Melinda sent an email and image, and wanted to know, “I break out in a rash when I encounter this plant just like poison ivy. And [do you have any] thoughts on that?”

A similar question occurred over a year ago in RSFF, and the answer is, “[It’s] Peppervine [and it’s] in the grape family. A lot of people mistake it for poison ivy, [and] other than being an aggressive grower, it’s harmless.” Peppervine is a mimic of poison ivy. AHA suspects there is poison ivy mixed in with the peppervine. The shape the leaflets of each plant can be similar. The leaflets of poison ivy grown in clusters of three while the leaflets of peppervine are five in a group.

Leafy Mistletoe

Randy is concerned about an oak tree and wrote via email, “I have a random oak tree that is infested with mistletoe, and I wanted to ask if there is anything I can do for the tree? The mistletoe is pretty much on every branch of the tree and seems to be killing all of them.”

An online search on treatments for leafy mistletoe entails pruning. However, with a heavy infestation shown in the image, University of Florida Extension shared some information about a chemical treatment, “A specialized growth regulating chemical can be applied to the mistletoe when the host tree is dormant, usually from December to early February. If applied while the tree is actively growing, this chemical--Ethephon--will damage the tree. Ethephon must be applied by a licensed pest control operator.” Florel™ is the brand name of an herbicide with ethephon and, in Louisiana, a licensed applicator can treat for leafy mistletoe.

Honeybee Removal

Bill is interested on being on the state list of beekeepers who catch swarms and remove unwanted hives from homes. The LSU AgCenter maintains a listing of beekeepers who are in the business of collecting bee colonies and placing them in hives.

If a homeowner discovers a honeybee infestation, a Google™ search with these words, “honeybee removal & swarm collection list”, will result in the AgCenter’s link at the top of the search listing. LSU AgCenter does not conduct bee swarm removals, rather the AgCenter simply maintains the list online. The contacts on the statewide list are provided as an informational service. The LSU AgCenter does not endorse, warrant, or recommend any person or business listed here. Fees of beekeepers depend on situation and travel distance.

If you want to contact Roots, Shoots, Fruits and Flowers, please send your questions and pictures to Keith Hawkins, Area Horticulture Agent (AHA), 337-463-7006 or khawkins@agcenter.lsu.edu. Also, you can be on the “green thumbs” email list by emailing your request to the address above.
