We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include 2 new phytoplasma species infecting apple trees in Iran, the first report of Colletotrichum asianum causing anthracnose on Willard mangoes in Sri Lanka and the first report of Groundnut ringspot virus in cucumber fruits in Brazil.
We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include Phytophthora cinnamomi in the rhizosphere of agricultural crops in southern Bahia (Brazil), the first report of Fusarium oxysporum f. sp. cubense tropical race 4 associated with Panama disease of banana outside Southeast Asia and the first report of ‘Candidatus Liberibacter asiaticus’ associated with Huanglongbing on Persian lime in Martinique and Guadeloupe.
We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include the first report of the dagger nematode in citrus orchards in Morocco, the first report of Neofusicoccum mangiferae causing rachis necrosis and inflorescence blight of mango in Puerto Rico and new records of three Ramichloridium species on banana leaves in Panama and Taiwan.
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
