|Sri Lankan tea estate, showing plots where tea workers grow vegetables.|
Project description: The objective is to
find environmentally acceptable methods for the control for four pests
infesting vegetable plots worked on by the tea community in Sri Lanka.
The present use of conventional pesticides poses a threat to the tea export
market and a demand that vegetable cultivation be stopped. The focus of
the project would be on the identification and development of methods
based on biopesticides and semiochemicals, which could be used to support
an integrated pest control strategy. The project would ensure the continued
availability of vegetable growing as an acceptable means of improving
tea worker incomes and thereby contribute to increase the incomes and
standards of living of this impoverished section of Sri Lankan society.
The expertise on semiochemicals in Uppsala will be made available to Sri Lankan researchers and part of the bioassay work will be carried out in Sweden.
In December 2008, Prof. Jan Pettersson, Prof. Savitri Kumar and their colleagues in the research project published an article based on the results from their research in Currents, Volume 44/45, a magazine from the Swedish University of Agricultural Sciences. The article is titled ”Sustainable plant protection for increased food security in a changing climate”. Read the article (as a pdf-file).
