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...

Navua sedge (Cyperus aromaticus) is an aggressive perennial sedge in pastures and crops in the wet tropical regions of Australia and numerous Pacific Island countries and territories. A biological control program was started in Australia to look for biological control agents for C. aromaticus in...

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...

This chapter documents the biological control efforts (targeted at arthropods, weeds and microorganisms) in the Eurasian region, highlighting a number of cases of successes and failures. It is indicated that despite a long history of importation biological control, the regulatory framework of the...

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...

Parthenium hysterophorus, commonly known as parthenium weed, is an invasive alien species in Pakistan. There are no specialized natural enemies native to Pakistan that attack the plant species inflicting serious damage and, thereby, keeping it under control. The rust species Puccinia abrupta var. ...

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 ...

A little known, unculturable ascomycete, referred to as Phyllachora ambrosiae, can destroy the inflorescences of Ambrosia artemisiifolia, an invasive agricultural weed and producer of highly allergenic pollen. The fungus often remains undetectable in ragweed populations. This work was conducted to...

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 ...

These proceedings contain 299 papers presented in the following sessions: (1) Target and agent selection, (2) Opportunities and contraints for classical weed biocontrol in developing countries, (3) Bioherbicides, (4) Novel methods to determine efficacy and environmental safety of agents, (5) Making ...
