Floods Stall Ivory Coast Cocoa Harvest

Heavy rains in Ivory Coast’s cocoa-growing areas are slowing the harvesting and sales of beans and farmers say they’re worried about black-pod disease rotting their crops. Roads to plantations in the southwestern area of Meagui have been cut off after rivers overflowed and farmers can’t access their crops, which means …

Botanists alarm over pests and diseases ravaging African forests

Virulent pests and diseases that are ravaging Africa’s forests with profound intensity pose new threats to their survival, experts said at a forum in Entebbe, Uganda on Wednesday. The experts drawn from the fields of botany and entomology noted that tree pests and diseases are spreading fast in many parts …

State of the World’s Plants 2017

The spread of pests and pathogens that damage plant life could cost global agriculture $540 billion a year, according to this report released by the Royal Botanic Gardens in London. An increase in international trade and travel had left flora facing rising threats from invasive pests and pathogens, and called …

Rapid transcriptional plasticity of duplicated gene clusters enables a clonally reproducing aphid to colonise diverse plant species

The prevailing paradigm of host-parasite evolution is that arms races lead to increasing specialisation via genetic adaptation. Insect herbivores are no exception and the majority have evolved to colonise a small number of closely related host species. Remarkably, the green peach aphid, Myzus persicae, colonises plant species across 40 families …

Wheat rust back in Europe

An infection that struck wheat crops in Sicily last year is a new and unusually devastating strain of fungus, researchers say — and its spores may spread to infect this year’s harvests in Europe, the world’s largest wheat-producing region. Original Source

New wheat diseases discovered in Morocco, Europe and Central Asia

Rabat – Two new fungal diseases capable of destroying whole wheat crops around the world have been discovered, with crops in the Mediterranean at particular risk, according to a study conducted by the Food and Agriculture Organization of the United Nations (FAO). One of the fungal diseases is called “TTTTF” …

Africa: New, Aggressive Rust Imperils Wheat Crops in Europe, Africa, Asia

Rome — Wheat rust, a family of fungal diseases that can cause crop losses of up to 100 per cent in untreated susceptible wheat, is making further advances in Europe, Africa and Asia, according to two new studies produced by scientists in collaboration with the United Nations. The reports, highlighted …

Resistance to cotton leaf curl disease in transgenic tobacco expressing βC1 gene derived intron-hairpin RNA

RNA silencing is an adaptive, inducible antiviral defence mechanism in the host against invading viruses. The adaptive antiviral function is characterized by the formation of virus-derived small interfering RNAs (siRNAs) during viral infection. As a counter defense strategy, a number of plant viruses evolve viral suppressors to target antiviral silencing. …

Historic late blight outbreaks caused by a widespread dominant lineage of phytophthora infestans (Mont.) de Bary

Phytophthora infestans (Mont.) de Bary, the causal agent of potato late blight, was responsible for the Irish potato famine of the 1840s. Initial disease outbreaks occurred in the US in 1843, two years prior to European outbreaks. We examined the evolutionary relationships and source of the 19th-century outbreaks using herbarium …

Harbouring public good mutants within a pathogen population can increase both fitness and virulence

Existing theory, empirical, clinical and field research all predict that reducing the virulence of individuals within a pathogen population will reduce the overall virulence, rendering disease less severe. Here, we show that this seemingly successful disease management strategy can fail with devastating consequences for infected hosts. We deploy cooperation theory …

Regional modeling of climate change impacts on smallholder agriculture and ecosystems in Central America

Climate change will have serious repercussions for agriculture, ecosystems, and farmer livelihoods in Central America. Smallholder farmers are particularly vulnerable due to their reliance on agriculture and ecosystem services for their livelihoods. There is an urgent need to develop national and local adaptation responses to reduce these impacts, yet evidence …

Corn mold lurks in U.S. fields, threatening crop yields

A fungal disease called Diplodia ear rot is lurking in corn fields in portions of the U.S. Midwest, and crop experts and farmers fear lower yields and crop damage that could force growers to accept steep discounts on the cash market. Diplodia, which causes a whitish mold between kernels, is …

Ivory Coast rains help main cocoa crop, some farmers fear disease

Light rains in most of Ivory Coast's main cocoa regions augur well for the crop in the world's biggest producer, farmers said on Monday, but cloudy weather has stoked fears of disease in the south. Farmers need the right mix of rain and sunny spells in July and August to …

Hail and fungi kill 200,000 pine trees at Kowen Forest

About 200,000 pine trees will have to be cut down in Kowen Forest, due in part to a "one-in-35-year" storm six months ago. More than 300 hectares of trees will have to be harvested early after a freak combination of hail and fungal damage wiped out about 6 per cent …

East Africa: Disease Still Ravaging Maize in East Africa

Arusha — East Africa is still struggling to eradicate the maize lethal necrosis disease (MLND), which has ravaged the crop in the northern regions of Tanzania and other East African countries since 2013. The Permanent Secretary in the Ministry of Agriculture, Livestock and Fisheries, Dr Florens Turuka, said although intensive …

European ruling on olive tree cull sparks fear in Italy

European countries can be forced to cull olive trees to stop the spread of a deadly bacterium, the European Union ruled on Thursday, sparking concern in a grove-dotted region of Italy. The EU court rejected an appeal from an Italian tribunal over a European Commission order to destroy all olive …

Devastating wheat fungus appears in Asia for first time

On 26 April, a team led by microbial population geneticist Daniel Croll, who is at the Swiss Federal Institute of Technology in Zurich, reported on github.com that the Bangladeshi wheat-blast strain is closely related to those collected in Brazilian wheat fields and on nearby weeds. His team’s analysis, which uses …

Scientists advance disease resistance in 3 of world's most important crops

Evanston, IL - Today's advanced online publication of the journal Nature Biotechnology carries three important papers on crop disease resistance. They report the isolation of novel disease resistance genes and the successful transfer of resistance into wheat, soybean, and potato. The 2Blades Foundation supported the development of these efforts as …

Pine wood cancer wreaks havoc in East China province

JINAN - Pines covering 7 million mu (470,000 hectares) in East China's Shandong province are under threat from pine wood nematode disease, the local forestry department said. Currently, pines in 98,000 mu across 13 counties have already been infected by the disease, which is moving rapidly toward the western part …
