New Wheat Rust Races Found in Europe, Africa, Central Asia
By Dipo Olowookere
Wheat rust, a family of fungal diseases that can cause crop losses of up to 100 percent in untreated susceptible wheats, is making further advances in Europe, Africa and Asia, according to two new studies produced by scientists in collaboration with FAO.
The reports, highlighted in the journal Nature following their publication by Aarhus University and the International Maize and Wheat Improvement Center (CIMMYT), show the emergence of new races of both yellow rust and stem rust in various regions of the world in 2016.
At the same time, well-known existing rust races have spread to new countries, the studies confirm, underlining the need for early detection and action to limit major damage to wheat production, particularly in the Mediterranean basin.
Wheat is a source of food and livelihoods for over 1 billion people in developing countries. Northern and Eastern Africa, the Near East, and West, Central and South Asia – which are all vulnerable to rust diseases − alone account for some 37 percent of global wheat production.
“These new, aggressive rust races have emerged at the same time that we’re working with international partners to help countries combat the existing ones, so we have to be swift and thorough in the way we approach this,” said FAO Plant Pathologist Fazil Dusunceli. “It’s more important than ever that specialists from international institutions and wheat producing countries work together to stop these diseases in their tracks − that involves continuous surveillance, sharing data and building emergency response plans to protect their farmers and those in neighboring countries.”
Wheat rusts spread rapidly over long distances by wind. If not detected and treated on time, they can turn a healthy looking crop, only weeks away from harvest, into a tangle of yellow leaves, black stems and shriveled grains.
Fungicides can help to limit damage, but early detection and rapid action are crucial. So are integrated management strategies in the long run.
Mediterranean most affected by new rusts
On the Italian island of Sicily, a new race of the stem rust pathogen −called TTTTF− hit several thousands of hectares of durum wheat in 2016, causing the largest stem rust outbreak that Europe has seen in decades. Experience with similar races suggests that bread wheat varieties may also be susceptible to the new race.
TTTTF is the most recently identified race of stem rust. Without proper control, researchers caution, it could soon spread over long distances along the Mediterranean basin and the Adriatic coast.
Various countries across Africa, Central Asia and Europe, meanwhile, have been battling new strains of yellow rust never before been seen in their fields.
Italy, Morocco and four Scandinavian countries have seen the emergence of an entirely new, yet-to-be-named race of yellow rust. Notably, the new race was most prevalent in Morocco and Sicily, where yellow rust until recently was considered insignificant. Preliminary analysis suggests the new race is related to a family of strains that are aggressive and better adapted to higher temperatures than most others.
Wheat farmers in Ethiopia and Uzbekistan, at the same time, have been fighting outbreaks of yellow rust AF2012, another race which reared its head in both countries in 2016 and struck a major blow to Ethiopian wheat production in particular. AF2012 was previously only found in Afghanistan, before appearing in the Horn of Africa country last year, where it affected tens of thousands of hectares of wheat.
“Preliminary assessments are worrisome, but it is still unclear what the full impact of these new races will be on different wheat varieties in the affected regions,” said Dusunceli. “That’s what research institutions across these regions will need to further investigate in the coming months.”

The United Arab Emirates has announced its decision to quit the Organisation of the Petroleum Exporting Countries (OPEC) to focus on national interests.
This dealt a heavy blow to the oil-exporting group at a time when the US-Israel war on Iran had caused a historic energy shock and rattled the global economy.
The move, which will take effect on May 1, 2026, reflects “the UAE’s long-term strategic and economic vision and evolving energy profile”, a statement carried by state media said on Tuesday.
“During our time in the organisation, we made significant contributions and even greater sacrifices for the benefit of all,” it added. “However, the time has come to focus our efforts on what our national interest dictates.”
The loss of the UAE, a longstanding OPEC member, could create disarray and weaken the oil cartel, which has usually sought to show a united front despite internal disagreements over a range of issues from geopolitics to production quotas.
UAE Energy Minister Suhail Mohamed al-Mazrouei said the decision was taken after a careful look at the regional power’s energy strategies.
“This is a policy decision. It has been done after a careful look at current and future policies related to the level of production,” the minister said.
OPEC’s Gulf producers have already been struggling to ship exports through the Strait of Hormuz, a narrow chokepoint between Iran and Oman through which a fifth of the world’s crude oil and liquefied natural gas supplies normally pass, because of threats and attacks against vessels during the war.
The UAE had been a member of OPEC first through its emirate of Abu Dhabi in 1967 and later when it became its own country in 1971.
The oil cartel, based in Vienna, has seen some of its market power wane as the US has increased its production of crude oil in recent years.
Additionally, the UAE and Saudi Arabia have increasingly competed over economic issues and regional politics, particularly in the Red Sea area.
The two countries had joined a coalition to fight against Yemen’s Iran-backed Houthis in 2015. However, that coalition broke down into recriminations in late December when Saudi Arabia bombed what it described as a weapons shipment bound for Yemeni separatists backed by the UAE.

Central Securities Clearing System (CSCS) Plc bested four price decliners on the NASD Over-the-Counter (OTC) Securities Exchange on Monday, April 27. The alternative stock market opened the week bullish during the session with a 0.03 per cent uptick.
According to data, the security depository company added N2.61 to its share price to close at N76.26 per unit compared with the preceding session’s N78.87 per unit.
As a result, the market capitalisation of the platform increased by N820 million to N2.425 trillion from N2.424 trillion, and the NASD Unlisted Security Index (NSI) gained 1.38 points to finish at 4,053.97 points compared with the 4,052.58 points it ended last Friday.
The four price losers were led by NASD Plc, which slumped by N3.80 to sell at N34.70 per share versus N38.50 per share. FrieslandCampina Wamco Nigeria Plc fell by N1.45 to N98.10 per unit from N99.55 per unit, Food Concepts Plc slid by 27 Kobo to N2.43 per share from N2.70 per share, and Geo-Fluids Plc dipped by 9 Kobo to N2.91 per unit from N3.00 per unit.

The first trading day of the week in the currency market was bearish for the Naira in the Nigerian Autonomous Foreign Exchange Market (NAFEX) on Monday, April 27.
Yesterday, it lost N5.80 or 0.43 per cent against the United States Dollar to trade at N1,364.24/$1, in contrast to the N1,358.44/$1 it was traded last Friday.
In the same vein, the Nigerian currency depreciated against the Pound Sterling in the official market by N13.70 to close at N1,847.72/£1 versus the preceding session’s N1,834.02/£1, and slumped against the Euro by N11.56 to sell at N1,602.29/€1 versus N1,590.73/€1.
Also, the Nigerian Naira tumbled against the greenback during the trading day by N5 to quote at N1,385/$1 compared with the previous rate of N1,380/$1, and at the GTBank FX desk, it traded flat at N1,370/$1.
The poor performance of the domestic currency could be attributed to liquidity shortage at the official currency market on Monday, which came amid surging demand for international payments. At $76.50 million, interbank liquidity printed higher across 79 deals, up from the $43.572 million reported on Friday.
Nigeria’s gross external reserves declined to $48.45 billion amid a month-long decline in inflows, amid uncertainties in the global commodity market. The depletion of foreign reserves could be partly attributed to the Central Bank of Nigeria’s intervention in the FX market.
The market remains perturbed by persistent concerns over liquidity constraints, policy transparency, and weakening confidence in Nigeria’s FX market, while boosters, including oil prices, continue to look rocky due to stalled discussions and unclear ceasefire negotiations between the US and Iran.
A look at the cryptocurrency market, Bitcoin (BTC) has been rejected near $79,000 three times in eight sessions, leaving the level as the de facto ceiling of its current trading range even as major cryptocurrencies trade lower over the past day. It lost 0.9 per cent to sell at $77,003.61.
Analysts say that upcoming US Federal Reserve policy decisions and top tech firms’ earnings this week could provide the catalyst to push bitcoin decisively above $80,000.
The market also continued to weigh Iran’s interim deal proposal to reopen the Strait of Hormuz, which failed to advance over the weekend. The White House said US officials were discussing the latest Iranian proposal but maintained “red lines” on any deal to end the eight-week war.
Solana (SOL) dropped 1.8 per cent to $84.25, Ripple (XRP) went down by 1.6 per cent to $1.39, Ethereum (ETH) depreciated by 1.3 per cent to $2,290.00, Binance Coin (BNB) declined by 0.5 per cent to $625.18, and Cardano (ADA) fell by 0.2 per cent to $0.2480.
However, Dogecoin (DOGE) rose by 2.0 per cent to $0.1002, and TRON (TRX) appreciated by 0.2 per cent to $0.3242, while the US Dollar Tether (USDT) and the US Dollar Coin (USDC) remained unchanged at $1.00 apiece.
