IOBC workshop 2019 group Delegates at the International Workshop on Biological Control and Management of Eupatorieae and other Invasive Weeds

By Chan Hong Twu, scientist at CABI Southeast Asia in Selangor, Malaysia

CABI Southeast Asia was proud to host the 9th International Workshop on Biological Control and Management of Eupatorieae and other Invasive Weeds where the very latest research on invasive weeds and their biological control agents were shared amongst delegates from 13 countries including Australia, New Zealand, South Africa, Fiji, India, Pakistan and other South East Asia countries.

The workshop in Putrajaya, Malaysia, a first for Southeast Asia, offered a valuable opportunity for researchers, professionals and students to gain awareness of the efforts on a regional scale, as well as country-driven biocontrol activities to address not only Eupatorieae weed but all invasive weeds in the regional countries.

New pest risk analysis decision support tool in development from CABI

Colorado beetle eats a potato leaves young.

A Pest Risk Analysis (PRA) allows National Plant Protection Organisations (NPPOs) to assess risks posed by pests or pathways of quarantine concern, and identify options to manage those risks. Recognising that there was a need for support in the completion of PRAs, CABI, under its Action on Invasives programme, has designed and is developing an online PRA tool.
