New plant disease records from CABI scientists in 2011
In 2011, CABI scientists helped to discover new occurrences of disease-causing phytoplasmas and fungi in Africa, Asia and Oceania. Our scientists, based in Egham in southeast England, provide the Plantwise diagnostic service free of charge to developing countries to support the plant clinics, which give advice to farmers with plant health problems. They work in…
Remote microscope networks enable long distance pest diagnoses
The Cooperative Research Centre for National Plant Biosecurity (CRCNPB) in Australia is developing a new way to share information on crop pests and diseases. In addition to providing diagnostic tools in the form of a database on plant pests similar to Plantwise’s Knowledge Bank, they have created an online remote microscope network, which “allows species…

New Technology Sniffing out Pests
A recent meeting of crop experts has revealed some new ideas for detecting the presence of crop pests before they strike. These ideas include sampling the air for pathogen traces, measuring volatile organic compounds and detecting decreases in leaf tissue content.
Understanding and managing aflatoxicosis outbreaks in Kenya
Aspergillus flavus and A. parasiticus are important fungal pathogens that infect a wide range of cereals, oil seeds and nuts. They produce toxic metabolites called aflatoxins (mycotoxins with carcinogenic and teratogenic properties) that can contaminate food products. Although strictly regulated around the world, aflatoxin contamination in developing countries is poorly regulated. In addition, limited management…
