Lifting baseless ban on weed killer, glyphosate
An open letter to the Minister of Agriculture
Mr. Minister,
You have recently, on several occasions, indicated your desire to lift the highly ill- conceived ban on glyphosate, and you should please do this immediately to help the farmers to cut down on their crop production costs. Use of glyphosate for tea has been allowed as from 2020 with Japan complaining of high MCPA herbicide residues in our tea following its use in place of glyphosate after the total ban of the latter.
Glyphosate was initially banned from use in the Districts of Anuradhapura, Polonnaruwa, Kurunagala and a part of Badulla in August 2014, but totally in 2015 in the entire country following a faulty claim by some Rajarata scientists based on their publication in an open access (fee-levying) journal that it was the cause of the Rajarata kidney disease (CKDu). This highly flawed paper was, ‘torn to bits’ by several reputed chemists. However, the authors together with a Buddhist priest, with no notion of science, had convinced the Yahapalana President that glyphosate was the cause! It is now known that the aetiolating agent of CKDu is hard water and fluoride in dug wells on high ground. Those who drank river or tank (surface) water did not contaminate the disease.
The October-2015 total ban in Sri Lanka may have also been prompted by the International Agency for Research on Cancer (IARC) decision to transfer glyphosate from the non-carcinogenic Class 3 to the ‘probably carcinogenic’ Class 2 A of the Carcinogenic Classification of substances. However, CKDu and cancer are totally different health conditions. Further the IARC classification is for identifying ‘hazard’ and not health ‘risk’. However several international organizations such as the Joint Meeting of the WHO-FAO on Pesticide Residues (JMPR) in 2016 clarified that there is no evidence to implicate glyphosate being toxic and any risk from its recommended use . This has also been echoed by other organizations such as the EU Commission on Chemicals, Environmental Protection Agency (EPA) of U.S , European Food Safety Authority, the British Royal Society and some twenty Nobel Laureates. Further, on 13th April 2016, the EU Parliament has backed a re-authorization of glyphosate for a further seven years.
The Agricultural Health Study which monitored the health of some 90,000 people in Iowa and North Carolina from 1993 to 2010, is probably the most comprehensive study that has cleared glyphosate of cancer or any other health risks. The findings are published in the Journal of National Cancer Institute (JNCL) 0f Nov. 2017. The subjects included farmers licensed to apply pesticides to crops and their spouses. The impact of more than 54,000 pesticide applications had been taken into account in this study of which 83% contained glyphosate. Many of the farmers had been using glyphosate even before the study. Yet after two decades of continuous and intense use of glyphosate there were no significant increase in cancer among those exposed to the herbicide. David Spiegelhalfer, a Cambridge University professor who was himself not involved in the study had confirmed according to press reports that ‘the analysis had been large and careful’ and shows no significant relationship between glyphosate use and cancer.
Further, a group of four independent panels of experts in 2016 looked at the relevant research on glyphosate and whether it is carcinogenic. The group which comprised 16 scientists, from Canada, the United States, Denmark, Brazil and the United Kingdom and other countries, decisively concluded that “glyphosate is unlikely to pose a carcinogenic risk to humans.”The authors rejected the findings of the International Agency for Research on Cancer (March 2015), which proposed that glyphosate is probably carcinogenic to humans.
Glyphosate is the most widely used pesticide (weed killer) in the world and its total annual global use exceeds the cumulative use of all other pesticides. This was also the situation in Sri Lanka. No official or specific authority in Sri Lanka has recommended banning glyphosate, and no one has come forward to officially explain why such a ban was imposed.
This ban is seriously affecting crop production in Sri Lanka as weed-management costs have sky rocketed especially with increased fuel costs. The Chairman of the Planters Association of Sri Lanka has reported recently that the tea industry had lost over 2 billion rupees in 2015 due to the ban. An MP confessed on TV that he uses black market glyphosate in his tea estate! In rice, pre-plant weed control was widely done with glyphosate but is now done by impounding water. As a result irrigated paddy cultivation, necessitates 20% more water, a highly valuable commodity, especially in the dry zone. The maize farmers in the dry zone complain that weeding costs have increased by 300% without glyphosate.
The Yahapalana government attempted to move away from agrochemicals and conventional farming. The then President enthuastically set up a project titled ‘Toxin- Free Agriculture’ under the ages of the Strategic Enterprises Management Agency (SEMA) to drive the local agriculture towards organic farming. But the project was an utter failure, and he disbanded it after several years. Not learning a lesson from it and rejecting the views of the majority of local scientists, the new President, Gotabaya Rajapaksa virtually overnight decided to terminate conventional agriculture and turn fully to organic farming which too has been an utter failure! The consequent mess the country’s agriculture has been put in is in evident to all. The country, or for that matter, the world cannot move away from conventional farming and agrochemical as, despite numerous promotions the whole world to date has only 1.5% in in organic agriculture. The country has now fortunately turned back to conventional farming and the necessary fertilizer and pesticides should be made available to the farmers as a matter of highest priority.
, In conclusion, even at this very late stage, if the government yet has doubts, it should do well to appoint a team of experts in the field to examine and report whether there is any positive evidence to implicate glyphosate in the aetiology of CKDu or cancer. The impact of the glyphosate ban on the agriculture of the country has been severe in that weed control costs have sky –rocketed. Farmers claim that they have to invest three to four times more for manual weeding after the glyphosate ban. It is sad that the government has totally overlooked the views of the majority of main stream scientists in banning glyphosate.
Misuse of agrochemicals conventional or organic is risky to living beings and to the environment and their correct use cannot be overemphasized. This has been best put by Bombastus Paracelsus (1493 -1541), the father of the science of pharmacology. He postulated that “all substances are poisons; there is none which is not a poison. It is the dosage that differentiates poison and remedy”.

Mr. Lakshman Balasuriya – not just my boss, but a father and a brother
It is with profound sadness that we received the shocking news of the untimely passing of our dear leader, Mr. Lakshman Balasuriya.
I first met Mr. Balasuriya in 1988 while working at John Keells, which had been awarded an IT contract to computerize Senkadagala Finance. Thereafter, in 1992, I joined the E. W. Balasuriya Group of Companies and Senkadagala Finance when the organization decided to bring its computerization in-house.
Mr. Balasuriya obtained his BSc from the University of London and his MSc from the University of Lancaster. He was not only intellectually brilliant, but also a highly practical and pragmatic individual, often sitting beside me to share instructions and ideas, which I would then translate directly into the software through code.
My first major assignment was to computerize the printing press. At the time, the systems in place were outdated, and modernization was a challenging task. However, with the guidance, strong support, and decisive leadership of Mr. Lakshman Balasuriya, we were able to successfully transform the printing press into a modern, state-of-the-art operation.
Mr. Balasuriya was a farsighted visionary who understood the value and impact of information technology well ahead of his time. He possessed a deep knowledge of the subject, which was rare during those early years. For instance, in the 1990s, he engaged a Canadian consultant to conduct a cybersecurity audit—an extraordinary initiative at a time when cybersecurity was scarcely spoken of and far from mainstream.
During that period, Senkadagala Finance’s head office was based in Kandy, with no branch network. When the decision was made to open the first branch in Colombo, our IT team faced the challenge of adapting the software to support branch operations. It was Mr. Balasuriya who proposed the innovative idea of creating logical branches—a concept well ahead of its time in IT thinking. This simple yet powerful idea enabled the company to expand rapidly, allowing branches to be added seamlessly to the system. Today, after many upgrades and continuous modernization, Senkadagala Finance operates over 400 locations across the country with real-time online connectivity—a testament to his original vision.
In September 2013, we faced a critical challenge with a key system that required the development of an entirely new solution. A proof of concept was prepared and reviewed by Mr. Balasuriya, who gave the green light to proceed. During the development phase, he remained deeply involved, offering ideas, insights, and constructive feedback. Within just four months, the system was successfully developed and went live—another example of his hands-on leadership and unwavering support for innovation.
These are only a few examples among many of the IT initiatives that were encouraged, supported, and championed by Mr. Balasuriya. Information technology has played a pivotal role in the growth and success of the E. W. Balasuriya Group of Companies, including Senkadagala Finance PLC, and much of that credit belongs to his foresight, trust, and leadership.
On a deeply personal note, I was not only a witness to, but also a recipient of, the kindness, humility, and humanity of Mr. Lakshman Balasuriya. There were occasions when I lost my temper and made unreasonable demands, yet he always responded with firmness tempered by gentleness. He never lost his own composure, nor did he ever hold grudges. He had the rare ability to recognize people’s shortcomings and genuinely tried to guide them toward self-improvement.
He was not merely our boss. To many of us, he was like a father and a brother.
I will miss him immensely. His passing has left a void that can never be filled. Of all the people I have known in my life, Mr. Lakshman Balasuriya stands apart as one of the finest human beings.
He leaves his beloved wife, Madam Janine, his children Amanthi and Keshav, and his four grandchildren.
May he rest in eternal peace.

Tribute to Ernest Thalayasingham MacIntyre
It is deeply painful to come to terms with the passing of Ernest Thalayasingham Macintyre. The news has left a silence that feels both personal and profound.
For me, this is not only the loss of an extraordinary playwright and thinker, but the loss of someone who shaped my intellectual journey at its very beginning. Ernest Macintyre wrote the Preface to my first book, Island to Island, which emerged from my doctoral research on his works, titled “Diasporic Longing and Changing Contours of Resistance in the plays of Ernest Thalayasingham Macintyre.” That gesture was not merely academic generosity. It was an act of faith, encouragement, and quiet mentorship that I will always hold close.
I knew him first through his work. Through his plays, his satire, his deep political consciousness, and his unwavering commitment to theatre as a living, breathing social force. He was a pioneer of Sri Lankan English theatre and an equally vital presence in Australian theatre, articulating the grief, longing, resistance, and resilience of diasporic life with rare clarity and compassion.
In recent days, I have found myself returning again and again to the Preface he wrote for my thesis. Reading it now, I am reminded of his intellectual sharpness, his generosity of spirit, and his belief that literature and theatre must bear witness to histories of displacement and struggle. His words continue to guide me, even in his absence.
Beyond the scholar and dramatist, Ernest Macintyre was, to me, a father figure. Someone I looked up to with deep respect, awe, and admiration. His presence offered reassurance. His encouragement gave courage. His legacy will remain a guiding light.
My heartfelt condolences to his family, to his loved ones, and to all those whose lives he touched through his work and his kindness. May they find strength in the immense legacy he leaves behind.
Ernest Macintyre’s voice will not fade. It will continue to live on in theatre, in literature, and in the countless minds he shaped across homelands and islands.
With remembrance, gratitude, and sorrow.

Appreciation: D. L. O. Mendis Visionary Engineer, Philosopher, and Mentor
Today, we honour the life and legacy of D.L.O. Mendis, a visionary engineer and philosopher whose contributions defined the standards of our profession. D.L.O. possessed a rare combination of analytical rigor and creative foresight. His numerous technical papers presented here and abroad related to water resources development stand as enduring monuments to his brilliance.
Beyond creating blueprints and technical specifications, D.L.O. presented bold ideas that challenged and strengthened our professional communities. He was a dedicated mentor to junior engineers, and a leader who firmly believed that engineering was, above all, a service to humanity. While we mourn this great loss, we take solace in knowing that his radical influence shaped our careers and the ethical code that governs our profession.
A Career of Integrity and Excellence
Throughout his career spanning more than 70 years, D.L.O. embodied the highest standards of integrity and technical excellence. He was particularly instrumental in advancing our
understanding of ancient irrigation systems, bridging the gap between historical wisdom and modern development.
Academic and Professional Journey
D.L.O.’s educational journey began at Ladies’ College(which accepted boys in lower grades at the time) before he moved to Royal College. He later entered the University of Ceylon as a member of the pioneering first batch of engineering students in 1950, graduating in 1954 in a class of nearly 25 students.
His professional path was distinguished and diverse:
Irrigation Department:
Served for nearly 10 years.
River Valleys Development Board (RVDB):
Contributed during the construction of the Uda Walawe reservoir.
Ministry of Plan Implementation:
Served as Deputy Director under Director M. S. M. De Silva, where his main contribution was the promotion of appropriate technology, particularly the advancement of historical Kotmale ironwork which has existed since the era of Parakrama Bahu the Great, and the South Eastern Dry Zone Project. (SEDZ).
Consultancy:
Served as a freelance consultant.
Leadership:
A prolific contributor of a large number of technical papers to the Institution of Engineers, Sri Lanka (IESL), eventually serving as its President.
Personal Reflections and Anecdotes
My association with D.L.O. spanned more than 50 years. I first saw him riding a bicycle past Akbar Hall while I was an engineering student. I later learned his family was residing at Prof. Paul’s residence nearby while he was serving at Uda Walawe Reservoir Project as a senior engineer for the RVDB.
Through D.L.O., I had the privilege of meeting legendary professionals outside the Irrigation Department, includingthe exceptionally bright M.S.M. de Silva and the international economist, Dr. Lal Jayawardena (Mr. N.U.Jayawardena’s son).
A Tribute to a Legacy
We extend our deepest gratitude for Mr. D.L.O. Mendis’slifelong service and offer our sincerest condolences to his family and colleagues. His monumental work and numerous publications remain a lasting gift to future generations of engineers.
