Plantwise, a global initiative run by CABI, was launched in Accra, Ghana last week. The initiative involves establishing plant clinics, which farmers can attend to get advice on plant health from trained plant doctors. In addition to the knowledge they acquire through the training programmes, these plant doctors can make use of the Plantwise Knowledge Bank which provides up-to-date information to best advise the farmer.
Following the launch, a review and planning workshop took place for stakeholders in the agricultural sector. The event attracted policy makers, extension workers, plant protection officers and researchers as well as private sector and non-governmental agencies who were all keen to share their knowledge and ideas on how to develop Plantwise activities in the country.

A species of whitefly that transmits cassava mosaic virus has been detected in South Africa for the first time. The whitefly, Bemisia tabaci is a cryptic species complex containing some important agricultural pests and virus vectors. The term ‘cryptic species complex’ means that Bemisia tabaci is considered to be a complex of at least 24 different species that look almost identical but are in fact genetically different. Researchers from a range of organisations including the University of Johannesburg, the University of Witwatersrand and ARC-Vegetable and Ornamental Plant Institute conducted surveys to investigate the diversity and distribution of Bemisia tabaci species in 8 provinces in South Africa. The study aimed to update the information regarding the different Bemisia tabaci types present in the country.

Striga, a parasitic weed (also known as Witchweed,) has long been a problem in African nations; causing farmers to lose billions of dollars’ worth of crops annually. To make matters worse, the weed flourishes in conditions that characterise that of poor farming communities (small plots, mono-cropping, lack of oxen and natural manure and lack of agricultural inputs.)

Guatemala has declared a state of agricultural emergency after coffee rust fungus has affected approximately 193,000ha of coffee, equating to 70% of the national crop. As a result of the outbreak, Guatemala is releasing $13.7m (£8.7m) in emergency aid to help farmers buy pesticides and to inform farmers on ways to manage the disease. Honduras and Costa Rica have already declared national emergency and El Salvador and Panama are also affected.
Coffee is a major export crop in many Central American countries and it is thought that this disease outbreak, which has been called “the worst seen in Central America and Mexico” by John Vandermeer, ecologist at the University of Michigan, will lead to big job losses. The Institute of Coffee in Costa Rica has estimated that the latest coffee rust outbreak may reduce the 2013-2014 harvest by 50% or more in the worst affected areas.
