Himalayan balsam (Impatiens glandulifera) is one of the most prolific non-native species in Europe. Since 2014, the highly-specific rust fungus, Puccinia komarovii var. glanduliferae, has been released into Great Britain as a classical biological control agent for this invasive weed. Prior to its...

Impatiens glandulifera, or Himalayan balsam, is a prolific invader of riverine habitats . Introduced from the Himalayas for ornamental purposes in 1839, this annual species has naturalised across Great Britain (GB) forming dense monocultures with negative affects across whole ecosystems. In 2006 a...

As the tenth anniversary of the adoption of the Nagoya Protocol on Access and Benefit Sharing (ABS) was reached, CABI reviewed its benefit sharing activities. CABI published its Nagoya Protocol Access and Benefit Sharing Policy online (CABI 2018a) and took a position to share benefits whether the...

Impatiens glandulifera or Himalayan balsam (HB), is an invasive alien weed throughout the British Isles (BI). Classical biological control of HB in the BI using a rust fungus from the Himalayan native range was implemented in 2014. However, not all HB populations are susceptible to the two rust...

In 2014, the rust fungus Puccinia komarovii var. glanduliferae, native to the foothills of the Himalayas from Kashmir to Western Nepal, became the first fungal agent to be released into Europe for the classical biological control of a non-native weed. The target, Impatiens glandulifera or Himalayan ...

Impatiens parviflora, commonly known as small balsam, is an invasive plant native to the mountains of central Asia. In September 2013, uredinia and telia of the rust fungus Puccinia komarovii were identified on the abaxial leaf surface of I. parviflora at Northchurch Common, Hertfordshire, UK. The...

Silva et al. (2012) found leaf spots on D. unguis-cati in Brazil caused by Pseudocercospora unguis-cati. Lesions are subcircular, well delimited, dark brown surrounded by a purplish brown halo, 2-6 mm, coalescing, and infection leads to severe defoliation. This was by far the most common disease of ...

Matrix-assisted laser-desorption and ionization time-of-flight mass spectroscopy (MALDI-TOF MS) is commonly used for the characterization of protein-containing biological samples. For this, we have previously developed sample-preparation methods that can be used for discrimination between Impatiens ...

Background: Matrix-assisted laser-desorption and ionisation time-of-flight mass spectroscopy (MALDI-TOF MS) is a powerful tool for the characterisation and/or identification of protein-containing samples. Several MALDI-TOF MS sample-preparation methods are currently available but few of these are...

Matrix-assisted laser-desorption and ionization time-of-flight mass spectrometry prepares proteins intact in the gas phase with predominantly a single positive charge. The times-of-flight of charged proteins along a tube held at high vacuum after acceleration in an electrical field are proportional ...
