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 collaboration with scientists from other institutions around the world to diagnose diseases that can’t be identified in the country that the diseases are found.
As farmers monitor their crops for pests and diseases, new discoveries are being made all the time. New species of pest are found, known pests pop up in a new place or find homes on new plant species. Increased globalisation has facilitated the spread of many pests; more complex trade and travel networks have led to more opportunities for pests to hitch a ride to a new place. Changes in climate can also change the suitability of regions to pests, leading to a spread to locations not previously threatened. When it has been confirmed that a pest has been found in a new place or on a new plant host, our scientists publish their report in a peer-reviewed journal such as New Disease Reports to communicate their findings to the wider scientific community. The following records are those co-authored by CABI scientists in 2011. Continue reading →
Biosecurity New Zealand announced on Saturday that samples of New Zealand pollen have tested positive for the bacterial kiwifruit disease, Pseudomonas syringae pv. actinidiae (Psa). Results indicate that Psa may have been present in New Zealand for a number of years. The confirmation of Psa in New Zealand comes as a huge blow to the country, where, until 18 days ago, the kiwifruit industry was considered disease-free and was happily producing and exporting a third of the worlds kiwifruits. Growers have never insured against disease because there has been no need to.
