New research confirms plant-killing black root rot in marijuana facility
The fungus that causes the plant disease black root rot has spread to cannabis plants beyond hemp, warns new research that identified the pathogen in a licensed commercial cultivation facility in British Columbia, Canada.
Black root rot can be fatal to cannabis plants, said Chris Dumigan, a Ph.D. candidate in biology at the University of British Columbia Okanagan who specializes in cannabis and is lead author of the new research in the academic journal Plant Disease.
“It’s growing on and inside your root tissue and then it’s causing the roots to die, and the plant will eventually die as a consequence of that,” Dumigan told MJBizDaily.
The affected marijuana facility in Cranbrook, B.C., “had to throw out a whole bunch of equipment, they had to get rid of a bunch of plants, because they had a fungus that was growing and taking hold of their facility,” he added.
“And if you can’t control that, you’ll face total crop destruction.”
Black root rot was previously documented in a hemp greenhouse in Kentucky in late 2019, according to a 2022 paper in the same journal.
The research marks the first report of “black root rot in high THC-containing cannabis,” the new paper notes.
Confirmation of black root rot in marijuana comes as the industry focuses on plant pathogens in light of the spreading impact of hop latent viroid.
However, David Kessler, chief science officer with Billerica, Massachusetts-based marijuana cultivation technology Agrify Corp., said he doesn’t expect black root rot will pose the same economic threat to the cannabis industry as does hop latent viroid.
“That said, those cultivators that are affected by this most certainly are going to feel that economic damage, but having it be pervasive through the industry is less likely,” said Kessler, who was not involved in the research.
‘More widespread than people think’
Commercial marijuana businesses should be aware that black root rot exists and poses “a threat to their bottom line,” cannabis researcher Dumigan said.
The B.C. outbreak occurred at a cultivation facility that uses aeroponics, a method that leaves plant roots exposed and feeds them with a mist of water and nutrients.
The grower contacted Dumigan after sending diseased plants for pathogen testing and receiving negative results.
“To me, it’s nothing to be ashamed of, because that facility is quite clean,” he said.
“It’s not an oversight on their part, they were more or less a victim of a lack of research in the area,” Dumigan continued.
“This thing is more widespread than people think.”
In Australia, the destructive effect of black root rot on cotton crops has led to it being declared a pandemic, according to the paper.
Cannabis hasn’t been subjected to “the same research as other crops of similar market value,” Dumigan said.
“So something like this can fly under the radar and still be discovered as a new pathogen in this crop in 2022, which I think is very interesting – but also points to a lack of knowledge about cannabis, cannabis cultivation and cannabis pathology.”
Considering that black root rot has also been documented in greenhouse-grown hemp on the opposite side of North America, Dumigan said he would be “highly surprised” if the disease was new to marijuana.
Infections might have been misclassified as another kind of root rot, he said.
Aeroponic question unanswered
It’s not surprising that black root rot would affect cannabis, said Kessler, Agrify’s chief science officer.
“It thrives in cool and wet conditions,” he explained.
In particular, Kessler suspects black root rot might be more likely in an aeroponic environment such as the B.C. facility where it was detected, as opposed to cannabis grown in a medium.
Aeroponic growing is not the typical method of commercial cannabis production.
It involves “a very humid, air-rich environment, and that is a really great place to grow fungus,” Kessler said.
Without the buffer of a growing medium, he added, cannabis can be subject to “much more rapid temperature swings.”
“And that can be something that helps promote these types of diseases,” he said.
“A lot of these fungal spores can survive significant amounts of time just waiting for the right host and environment before they will – if you will – sprout and replicate.”
University of British Columbia Okanagan researcher Dumigan said the B.C. aeroponic facility in question grew “really robust cannabis plants that were disease-free for the longest time” using a pathogen control method.
“I do wonder whether it’s this unique (aeroponic) environment that really allowed this fungus to take hold in this facility,” Dumigan said.
Despite that theory, Dumigan cautioned that the research does not prove any link between black root rot and aeroponic cannabis cultivation.
“Since (the aeroponic facility has) been able to deal with this pathogen – monitoring it closely, always watching the roots – they haven’t had any issues and they have really good healthy crops,” he said.
More research needed
Dumigan and his colleagues isolated the black root rot sample from the Canadian facility into a culture and sequenced its genome for the first time, allowing them to further study the fungus.
“But what’s really interesting (is), we can start to develop diagnostic tests that use (genome) sequence information to determine when it is there and when it is not,” Dumigan told MJBizDaily.
Dumigan said he’s interested in developing new tests to detect the presence of black root rot in wastewater.
Early detection is “imperative,” he said.
“Because if you don’t detect it early, you can’t quarantine the infected crops, and it’s just going to spread through your facility.”
In the meantime, Dumigan has shared a technical bulletin about black root rot in cannabis on LinkedIn.
He said more research on black root rot in cannabis could include researching ways to combat the threat, such as microorganisms that produce antifungal compounds.
Anecdotally speaking, Dumigan said, “we’ve seen genotype-specific resistance to this and that some cultivars of cannabis will show more resistance than others.”

EU Pressure Builds on Google as Regulators Face Calls for Massive Fine Over Search Practices
A growing coalition of European industry groups is intensifying pressure on regulators to take decisive action against Google over allegations of unfair search practices that could reshape competition rules across the region’s digital economy.
Investigation Under Digital Markets Act Gains Momentum
The case is being examined by the European Commission under the European Union’s landmark Digital Markets Act (DMA), introduced to curb the dominance of major technology platforms and ensure fair competition.
Launched in March 2024, the investigation focuses on whether Google has been prioritising its own services in search results, potentially disadvantaging rival businesses that rely on online visibility to reach customers.
Industry Groups Demand Swift Action
Several prominent European organizations have jointly urged regulators to conclude the probe without further delay. They argue that prolonged investigations allow alleged anti-competitive practices to continue, putting European companies—especially startups—at a disadvantage.
Signatories include the European Publishers Council, the European Magazine Media Association, the European Tech Alliance, and EU Travel Tech.
In a joint statement, these groups warned that delays in enforcement are affecting innovation, profitability, and growth prospects for regional businesses competing in digital markets.
Google Denies Allegations
Google has rejected claims of bias, stating that its search algorithms are designed to deliver the most relevant and useful results to users. The company has also proposed adjustments to address regulatory concerns.
However, critics argue that these changes are insufficient and fail to address the core issue of market dominance.
Potential Billion-Euro Penalties
If found in violation of the DMA, Google could face significant financial penalties. Under EU rules, fines can reach a substantial percentage of a company’s global turnover, potentially amounting to billions of euros.
Regulators may also impose corrective measures requiring changes to business practices, which could have long-term implications for how digital platforms operate in Europe.
Wider Implications for Big Tech
The case highlights ongoing tensions between European regulators and major U.S. technology firms. In recent years, the EU has taken a more aggressive stance in enforcing competition laws, aiming to create a level playing field for local businesses.
A final ruling against Google could set a major precedent, influencing future enforcement actions and shaping the regulatory landscape for global tech companies operating within Europe.
As scrutiny intensifies, the outcome of the investigation is expected to play a critical role in defining the future of digital competition across the European Union.

Amazon Faces Potential Criminal Trial in Italy Over €1.2 Billion Tax Evasion Allegations
Milan: U.S. tech giant Amazon is facing the prospect of a major legal showdown in Italy, after prosecutors in Milan formally requested a court to move forward with criminal proceedings over alleged tax evasion totaling approximately ₹12,500 crore (€1.2 billion).
The case targets Amazon’s European division along with four senior executives, marking one of the most significant tax-related investigations involving a global e-commerce platform in Europe.
Trial Push Despite Multi-Million Euro Settlement
The move comes even after Amazon reached a financial settlement with Italian tax authorities in December, agreeing to pay around ₹5,500 crore (€527 million), including interest, to resolve part of the dispute.
Typically, such settlements lead to the closure of criminal investigations. However, Milan prosecutors have opted to proceed, signaling a tougher stance on alleged corporate tax violations.
A preliminary hearing is expected in the coming months, where a judge will decide whether to formally indict the company and its executives or dismiss the case.
Allegations of VAT Evasion Through Marketplace Sellers
At the center of the investigation are claims that Amazon’s platform enabled non-European Union sellers to avoid paying value-added tax (VAT) on goods sold to Italian consumers between 2019 and 2021.
Prosecutors allege that the company’s marketplace structure allowed thousands of foreign vendors—many reportedly based in China—to operate without fully disclosing their identities or tax obligations. This, authorities argue, led to substantial VAT losses for the Italian government.
Under Italian law, online platforms facilitating sales can be held partially liable if third-party sellers fail to comply with tax requirements, a key point in the prosecution’s case.
Italian Government Named as Affected Party
In their filing, prosecutors identified Italy’s Economy Ministry as the injured party, citing significant financial damage resulting from the alleged tax evasion.
Legal experts say the outcome of the case could have wide-ranging implications across the European Union, where VAT systems are harmonized and similar compliance rules apply to digital marketplaces.
Multiple Investigations Add to Pressure
The VAT probe is just one of several legal challenges facing Amazon in Italy. The European Public Prosecutor’s Office is reportedly examining additional tax-related issues covering more recent years.
Meanwhile, Milan authorities are pursuing separate investigations into alleged customs fraud linked to imports from China and whether Amazon maintained an undeclared “permanent establishment” in Italy—potentially exposing it to higher tax liabilities.
In a separate regulatory action, Italy’s data protection authority recently ordered an Amazon unit to stop using personal data from over 1,800 employees at a warehouse near Rome.
Amazon Denies Allegations
Amazon has consistently denied wrongdoing and indicated it will strongly contest the allegations in court if the case proceeds. The company has also warned that prolonged legal uncertainty could impact investor confidence and Italy’s appeal as a destination for international business.
Broader Impact on Europe’s Digital Economy
If the case moves to trial, it could become a landmark moment for the regulation of global e-commerce platforms in Europe. Governments across the region are increasingly scrutinizing how digital marketplaces handle tax compliance, especially in cross-border transactions.
With online retail continuing to expand, regulators are under mounting pressure to ensure that multinational platforms and third-party sellers adhere to the same tax rules as traditional businesses.

IndiGo Crisis Exposes Risks of Monopoly: What If Telecom or E-commerce Collapses Next?
Airports across India witnessed scenes of distress and confusion as thousands of passengers were stranded due to IndiGo’s massive flight disruptions. Families with medical emergencies, funerals, and personal crises were left helpless as the airline cancelled hundreds of flights without adequate communication or support.
Passengers described desperate situations — a mother pleading for sanitary pads for her daughter, a woman unable to transport her husband’s coffin, and others stranded while trying to reach family funerals or hospitals. “It was like a lockdown at the airport,” one passenger said, describing the panic that unfolded as IndiGo’s mismanagement crippled operations nationwide.
Root Cause: IndiGo’s Market Monopoly
The turmoil, industry experts argue, stems from IndiGo’s monopolistic control over India’s domestic aviation market. The airline operates nearly 2,100 flights daily and holds around 60% market share — meaning every second plane flying within India belongs to IndiGo.
This dominance has given the company unparalleled influence. When IndiGo falters, the entire aviation system suffers. Passengers are left with few alternatives, as other airlines lack capacity to absorb stranded travellers. The result: skyrocketing ticket prices, chaos at terminals, and total dependence on a single private operator.
Aviation pioneer Captain G.R. Gopinath, founder of Air Deccan, criticised the government’s inaction, noting that on some routes, IndiGo’s economy fares surged to ₹1 lakh. He compared the situation to a hostage crisis, writing that the airline “held the system ransom” and forced regulators to defer new safety rules meant to protect pilots and passengers.
Government Intervention and Regulatory Weakness
The crisis erupted after IndiGo failed to comply with the Flight Duty Time Limitations (FDTL) — rules introduced by the DGCA in January 2024 requiring adequate rest for pilots. Despite having nearly two years to adapt, IndiGo blamed the rule for operational disruptions, citing a shortage of pilots.
Under mounting public pressure, the government stepped in, temporarily relaxing FDTL norms and capping airfare hikes. Officials claimed the move was to protect passengers, but analysts say it exposed the state’s vulnerability to corporate monopolies. “The government had no option but to yield,” said one aviation policy expert, pointing out that ignoring safety regulations for short-term relief could have long-term consequences.
The crisis also rekindled memories of the June 2025 Air India crash near London, which claimed over 240 lives. Experts warn that compromising pilot rest and safety standards to maintain flight schedules could risk another tragedy.
If Telecom Giants Fail: A National Paralysis
The article raises a troubling question — what if a similar crisis struck the telecom sector, where Jio and Airtel together control nearly 80% of subscribers and serve over 780 million users?
If both networks failed simultaneously, the repercussions would be catastrophic. Internet shutdowns would halt UPI transactions, online banking, OTP verifications, video calls, OTT streaming, and emergency communications. Critical services such as airports, hospitals, stock exchanges, and small businesses — many of which rely on WhatsApp and digital payments — would come to a standstill.
In essence, a telecom breakdown could paralyse India’s digital economy, exposing the nation’s dependence on a duopoly.
E-commerce Monopoly: Another Fragile Ecosystem
The same risk looms over the e-commerce sector, where Amazon and Flipkart dominate nearly 80% of the market. A disruption similar to IndiGo’s could cripple daily life — halting delivery of groceries, medicines, and essential goods, freezing refunds and customer support, and leaving small sellers without platforms to trade.
Local retailers, freed from competition, might exploit shortages by inflating prices. Such a scenario underscores the perils of market centralisation in sectors critical to everyday living.
A Wake-Up Call for Regulators
The IndiGo crisis, analysts say, is a warning shot for policymakers and regulators. A single company’s operational failure exposed systemic weaknesses in India’s infrastructure and consumer protection mechanisms.
As the aviation regulator DGCA investigates and IndiGo works to restore normalcy, the broader lesson remains clear: unchecked monopoly power in any essential service — whether air travel, telecom, or e-commerce — poses a direct threat to economic stability and citizen welfare.
Without stronger competition laws, redundancy frameworks, and regulatory oversight, India risks repeating this crisis across multiple sectors — each time with millions of citizens paying the price.
