Here’s a taste of some of the latest stories about plant health, including how technology could increase Citrus yields in Pakistan by 30%, what scientists in Kenya are doing to eliminate devastating wheat rust and a global maps of the gap between potential and actual yields of wheat and maize.
Last week, 193 Member States of the United Nations adopted the new Sustainable Development Agenda to end poverty by 2030. This came at the beginning of a three-day Summit on Sustainable Development during which focussed on implanting changes that will see the Agenda achieve its ambitious aims. The Agenda, consisting of 17 Sustainable Development Goals (SDG), will help countries to develop their policies over the next 15 years.
Plantwise have recently been investigating APHLIS data, a great source of information on postharvest losses in Sub-Saharan Africa. The system is run by a network of local experts who collect and supply data. Using a shared database and a Losses Calculator APHLIS provide estimates of weight losses for cereal grains at a national and provincial level. Continue reading →
Here’s a taste of some of the latest stories about plant health, including Striga resistant maize yielding well in Kenya, scientists in the UK finding a potential way to control leaf blotch disease in wheat and a grant under the Competitive African Rice Initiative (CARI) to help small scale rice producers by creating better linkages in the rice value chain.

On Friday, the International Plant Protection Convention (IPPC) released an official pest report, submitted by KEPHIS, for the presence of Maize lethal necrosis disease (MLND) in Kenya. This disease is caused by a co-infection of Maize Chlorotic Mottle Virus and another cereal potyvirus, such as Sugarcane Mosaic Virus, Wheat Streak Mosaic Virus or Maize Dwarf Mosaic Virus. This co-infection causes more severe symptoms that either of the viruses causes alone. Symptoms include mottling, stunting, necrosis and malformed ears.
MLND can devastate maize crops, impacting farmers’ incomes and the food security of the area. To find out how to recognise and control MLND, read the Plantwise Factsheet for Farmers created by employees from the Ministry of Agriculture and CABI.
Transgenic Bt crops have been grown around the world since the 1990s and have contributed to increased yields by controlling agricultural pests. Due to the importance of this technology, there has been continuous study into the development of resistance to Bt crops and how best to avoid this happening. A recent investigation into the rapid spread of Bt resistance in South Africa has revealed one of the more surprising discoveries to date, that the maize stalk borer (Busseola fusca) has evolved Bt maize resistance inherited as a dominant trait for the first time. This has significant impacts on the management of Bt crops, as current methods for sustaining susceptibility rely on the recessive inheritance of Bt resistance.
Here’s a taste of some of the latest stories about plant health, including reports of citrus greening (huanglongbing) in Paraguay, the discovery of genes resistant to Phytophthora sojae in soybeans and a computer model that gives early warning signs of crop failure.
