Last week in the Nkhotakota region of Malawi a new radio show went on air. Not a news programme or a music show, but a show devoted to Cassava. Sounds pretty specific? Well, it’s even more focussed than that. The weekly 30 minute programme is actually focussed on managing one of Cassava’s most damaging diseases – Cassava mosaic disease.

Following Claire’s series of posts on ‘making the most of the Plantwise knowledge bank’, I’d now like to introduce our next mini-series, which asks our country partners for their favourite recipes using top crops brought into plant clinics in their countries, so we can share them with you! Our first recipe comes from Hannah Serwaa Numah, who is the National Data Manager for Ghana. She tells us how to cook okro stew and akple, which is a traditional Ghanaian dish made from dried corn flour.

Grand Challenges – inspiring next generation plant pathologists

Julie Flood, Phil Taylor and Claire Beverley attended the ‘Grand Challenges in Plant Pathology study group’ event at the Doctoral Training Centre, University of Oxford, 14-16 September. The event was the first of its kind, aiming to engage and inspire the next generation of plant pathologists.

Biotechnology lab The event was sponsored by the British Society of Plant Pathology (BSPP), the American Phytopathological Society (APS) and CABI, and saw 5 real problems posed by industry and non-academic organisations to a group of 27 young scientists, post-docs and graduate students, in all aspects of plant pathology and plant sciences.

South American tomato leaf miner, Tuta absoluta, reported in Nepal for the first time

South American tomato leaf miner, Tuta absoluta (Meyrick), has been reported in a tomato farm for the first time in Nepal and the presence has been confirmed in five districts, Kathmandu, Lalitpur, Bhaktapur, Kavrepalanchowk and Dhading district. Studies carried out by the Nepal Agricultural Research Council (NARC) in May and June this year have identified and confirmed the presence of the pest in 14 locations in the five districts mentioned above. The highest infestation was identified in two districts, Ugrachandi Nala-2 and Panchakhal of Kavrepalanchowk district.

La Necrosis letal del maíz amenaza la producción en América del Sur

La enfermedad conocida como la necrosis letal del maíz (MLN, por sus siglas en inglés), causada por la co-infección de dos virus, está amenazando la producción de maíz en el Ecuador. Según el Ministerio de Agricultura, la incidencia y severidad de la enfermedad fue de casi 14% en 2016 y estaba presente en las provincias de Guayas, Los Ríos, Manabí y Loja. Aunque no está claro cómo y cuándo la enfermedad entró en el país, se están haciendo esfuerzos por las organizaciones nacionales de protección fitosanitaria para controlar la propagación de la enfermedad, así como para cuantificar los daños.

Esta enfermedad es causada por la co-infección del virus del moteado clorótico del maíz (MCMV) y del virus  mosaico de la caña de azúcar (SCMV). En África, se detectó la enfermedad por primera vez en 2011 en el distrito de Bomet, Kenia. En 2012 un estudio realizado en los distritos de Bormet y Naivasha, Kenia, mediante la secuenciación de alto rendimiento de muestras de hojas de maíz recogidas en la clínica de plantas Plantwise, ayudó a confirmar la presencia del virus MCMV y SCMV en el maíz (Adams et al., 2012). Debido a  que la enfermedad puede propagarse rápidamente (en menos de una semana), en  4 años se han reportado casos de la sintomatología de la enfermedad en Tanzania, Ruanda, Uganda, Sudán del Sur y la República Democrática del Congo (RDC), y su presencia se confirmó en Tanzania y RDC en 2012 (Makumbi & Wangai, sin fecha).

Effective surveillance and integrated pest management could curb the devastating impacts of tomato pest, Tuta absoluta, also called tomato leaf miner, which is ravaging the crop in Nigeria, experts say.

T. absoluta has affected most parts of northern Nigeria tomato farms in Kaduna state, causing a loss of more than 1 billion naira (about US$3.5 million), leading to rising tomato prices, according to the Centre for Agriculture and Biosciences International (CABI) — an organisation working with African governments and research institutions to monitor the spread of the pest.

Farming First and GACSA launch creative partnership to explore “Climate-Smart Agriculture in Action”

Contributed by Farming First

CSAOne billion farmers all over the world, responsible for growing the food the feeds the planet, are under unprecedented pressure from a changing climate. For eight months in a row now, temperatures have been the highest on record. Food shortages are affecting an estimated 100 million people in the wake of drought prompted by the strongest El Niño we have ever seen.

We urgently require ways of helping farmers preserve food security, and adapt to these harsher realities. We also need to ensure farmers can be part of the solution to climate change, given that food systems account for 19-29% of total greenhouse gas emissions.
