Release and Source Information

List: 1 - Exotic Organisms Intentionally Introduced

Source: Ex. India
Year: 2014
Region: Europe_Eurasia
Country: England
Subregion of Country:
Subregion specific:

Release History: 2014–2020

Release Notes: Releases/inoculations ongoing. Due to the genetic variation of Impatiens glandulifera in the United Kingdom, different populations differ in their susceptibility to various strains of the rust. The India strain was released in 2014, and the Pakistan strain was released in 2017 in an attempt to increase establishment on more I. glandulifera populations.

Agent Impact

Impact: Too early post release
Geographic Scale of impact: Too early post release
Impact Notes: Initially limited field establishment likely due to unsuitable site conditions (shade) as well as genetic variation of Impatiens glandulifera in the United Kingdom and variation in susceptibility to this Indian rust strain. Too soon following release to determine overall impact, but initial results promising on susceptible genotypes.
