El caserío Secsemayo pertenece al Centro Poblado Chamis, distrito Cajamarca, en la región Cajamarca; está ubicado a 20 kilómetros en dirección al sur – oeste de la ciudad capital, geográficamente enclavado en los andes cajamarquinos a 3,200 m.s.n.m.; bajo estas condiciones, la papa es el principal cultivo, cuya producción se destina íntegramente al consumo y seguridad alimentaria de aproximadamente 150 familias rurales.
Bacterial wilt (Ralstonia solanacearum) is one of the world’s most devastating plant diseases, with major crops such as tomato, potato and pepper being severely affected. Until now, crop breeders and farmers have had to simply wait for their crops to mature to determine the level of resistance to the disease. New research has shown that with modern metabolomics technology, it is possible to determine the level of disease resistance in plants much earlier at the seedling stage. This development could save both farmers and breeder time and money when growing host crops, and reduce the yield losses caused by the bacterial disease.
On the 16th October, World Food Day events will take place around the globe to draw attention to the growing problem of world hunger and malnutrition.
Shockingly, the FAO has reported that 10% of the global population experienced severe food insecurity in 2017 and that world hunger has increased for the third consecutive year. Key drivers in this trend have been recent climate variations and extreme weather events and increasing impacts of pests and diseases.
Located in semi-arid Eastern Kenya, Machakos county is home to the Umatui amazing site women group. The group comprises 15 members who mainly grow tomatoes, cowpeas, pigeon peas, and maize. It is among eight other women groups working with Katoloni Community Based Organisation (CBO), a non governmental organization under infonet biovision. The CBO runs a mobile Plant Clinic in Machakos county, Kenya and mostly targets organized farmer groups.
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 sweet potato Badnavirus in South Africa. The first report of Arabis mosaic virus in rhubarb in Poland and the first report of maize yellow mosaic virus on corn in South Korea. Continue reading →
The Plantwise training for plant doctors (Module 1: Field diagnostics and plant clinic operation) is unique in that it is the only international training that focuses on field diagnosis and uses live plant samples in the learning process. The training takes advantage of the fact that many of the symptoms caused by the different groups of pathogens are often similar irrespective of the host plant. The training has been widely praised by those just starting a career in field diagnostics as well as those trained to PhD levels as it is rare that the symptoms are laid out in this way.
