The spread of pests and pathogens that damage plant life could cost global agriculture $540 billion a year, according to a report published on Thursday.
The report, released by the Royal Botanic Gardens (RBG) at Kew in London, said that an increase in international trade and travel had left flora facing rising threats from invasive pests and pathogens, and called for greater biosecurity measures.
A facility has been launched in Kenya to aid commercial production of a protein bait to control fruit flies in Sub-Saharan Africa. The US$250,000 facility, which resulted from public-private partnership involving the International Centre of Insect Physiology and Ecology (icipe) and Kenya Biologics Ltd, will enable smallholders control fruit flies that devastate their fruits and vegetables.
Mr. Guze Kampinga visits the plant clinic at Dowa Turn Off with his damaged maize samples and is received by Mrs Eluby Phiri a trained plant doctor.
“I have grown about 0.8 ha of rain-fed and 0.4ha irrigated maize (Ndimba). This year a strange pest has seriously damaged my maize and almost all people in this village are experiencing the same problem. The pest started damaging the crop a few weeks after germination and has continued damaging the crop up to now. I first noticed the tips of the maize funnel chewed and stunting yet I had applied fertilizer and there was sufficient moisture. When I checked the funnel I found small caterpillars inside, which were growing very fast. Later the leaves were chewed and holes seen in the cobs, they also feed on the kernels. I have tried to control the pest to no avail”, said Mr Guze.
Home gardening enthusiasts and farmers from as far as Rio Claro seized the opportunity to have their plant sicknesses diagnosed at a plant clinic hosted by Trinidad and Tobago’s Ministry of Agriculture, Land and Fisheries (MoALF) at its Farmers’ Training Centre in Centeno. After a in-depth one-on-one discussion with Ministry representatives from the Extension, Training and Information Services Division (ETIS), participants were each given a prescription sheet which captured a host of valuable information, including a description of the plant problem and the recommended control measures.
As part of its mass extension activities for 2016, Plantwise Ghana rolled out a four-week radio campaign to educate farmers about the detection and management of crop pests and diseases prevalent in the project’s five intervention regions in Ghana. The campaign, which took place between September and October 2016, involved five radio stations noted for their experience in running agriculture-oriented programs targeted at farmers in those regions.
New research by CABI reveals that just five invasive alien species are causing US$0.9 – 1.1 billion in economic losses to smallholder farmers across six eastern African countries each year, equating to 1.8% – 2.2% of total agricultural GDP for the region. These losses are expected to grow to $1.0 – 1.2 billion per year over the next 5-10 years, highlighting the urgent need for coordinated responses at regional, national and international levels.
New research published in the open-access journal Global Food Security estimates the alarming level of economic losses suffered by smallholder farmers each year in eastern Africa, to a handful of species that have become damaging crop pests since their introduction to the region. These few invasive species can have devastating impacts on important staples such as maize, but also high-value crops including tomatoes, peas and green beans.
