Imported fungi help farmers defend themselves against invasive weeds. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Summary for Project titles: R8228: Classical biological control of Mikania micrantha with Puccinia spegazzinii: Implementation Phase and R8502: Promotion of Weed Biocontrol in Asia: the Mikania micrantha Experience.

A rust fungus collected in Trinidad and Peru is helping to control Mikania micrantha in southwest and northeast India. Previously, this invasive ('mile-a-minute') weed smothered vegetation over vast areas of tropical forests. Smallholder farmers can now fight back using biological control methods. The Indian Government provided a national framework for the project and sponsored public awareness activities to promote understanding of the control technology. Indian scientists and extension workers received training and are now undertaking on-going monitoring programmes. The rust fungus is being mass-produced in specially built facilities for wide release on the continent. Scientists in China, Fiji, Taiwan and Papua New Guinea are also using the technique, and many other countries have expressed interest.

The CD has the following information for this output: Description, Validation, Current Situation, Current Promotion, Impacts On Poverty, Environmental Impact. Attached PDF (12 pp.) taken from the CD.
