First record of alien species Toxicodendron radicans (Anacardiaceae) in Lithuania

Botanica
In the summer of 2025, a population of Toxicodendron radicans (L.) Kuntze, commonly known as eastern poison ivy, was discovered growing behind the Kaunas Botanical Garden in Lithuania. The discovered population of Toxicodendron radicans was observed occupying two contrasting habitat types: grassland and a nearby woodland.

New GLC Analysis of Urushiol Congeners in Different Plant Parts of Poison Ivy, Toxicodendron radicans

Journal of Pharmaceutical Sciences, 1978
Methods are presented for the direct GLC analysis of the catechol C15 alkenyl side-chain congeners contained in the urushiol fraction of poison ivy (Toxicodendron radicans) and the C17 homologs of poison oak (Toxicodendron diversilobum). A number of liquid phases were investigated and demonstrated varying degrees of separation.

Notes on a recent case of poisoning caused by the exhalation of rhus radicans (Toxicodendron) at the botanical gardens, Hobart.

Papers and Proceedings - Royal Society of Tasmania
A very peculiar case of poisoning, caused by plant exhalation, having occurred at these gardens, it is desirable that it should be recorded, not alone for general information, but more especially as it is possible that the plant in question may, to a limited extent, be under cultivation in other places.

Assessing poison ivy (Toxicodendron radicans) presence and functional traits in relation to land cover and biophysical factors

Physical Geography, 2021
Understanding species distributions remains central to research in ecology and biogeography. Emphasis is placed on the spatial presence/absence of plants as related to underlying environmental fact...

Catecholic and other constituents of the leaves of Toxicodendron radicans and variation of urushiol concentrations within one plant

Phytochemistry, 1980
Abstract Extracts of T. radicans were prepared for GC-MS by ethanol extraction of individual leaves followed by silylation. Analyses for the urushiol components were performed by monitoring ions at m/e 179 and the molecular ions of the various olefins.

Poison Ivy (Toxicodendron radican) Control with Triclopyr and Metsulfuron, Applied Alone and in Tank Mixture

Weed Technology, 2013
Dermatitis from poison ivy is an important health problem, and considerable effort is devoted to the control of this virulent weed. Triclopyr, metsulfuron, and two fixed-ratio tank mixtures of triclopyr and metsulfuron were evaluated across a series of rates for poison ivy control. The objective was to test whether tank mixtures are more effective than

Poison Ivy (Toxicodendron radican) Control with Dicamba and 2,4-D Applied Alone and in Tank Mixture

Weed Technology, 2015
Poison ivy is a virulent weed that is frequently treated with herbicides. Dicamba, 2,4-D, and two fixed-ratio tank mixtures of dicamba plus 2,4-D were evaluated across a series of rates for poison ivy control. Objective was to test whether tank mixtures were more effective than either herbicide applied alone.

Rising Atmospheric Carbon Dioxide and Potential Impacts on the Growth and Toxicity of Poison Ivy (Toxicodendron radicans)

Weed Science, 2007
Because of its ability to induce contact dermatitis, the establishment and spread of poison ivy is recognized as a significant public health concern. In the current study, we quantified potential changes in the biomass and urushiol content of poison ivy as a function of incremental changes in global atmospheric carbon dioxide concentration (CO2).
