The All Assam Small Tea Growers’ Association has pledged to work to improve the quality of Assam tea. The association has appealed to its members to stop using banned pesticides. They are conducting workshops to raise awareness about tea safety and permissible pesticides. And seem keen to change the perception that small tea growers are dragging down the quality of tea. Some samples of green leaf from small tea growers got a clean chit after testing at the Tea Research Association at Jorhat. What they seek in return for producing clean leaf is remunerative prices.
India Tea Production for 2024 Sees 60 Million Kilo Decline
The Tea Association of India has issued a press release to raise concerns about the drastic drop in tea production in north India in the first and second flush. The cause has been the severe lack of rainfall and excessive heat which this region has seen all year. The Association estimates a reduction of around 60 million kilograms by the end of June 2024, compared to the same period last year. By April, Assam had an 8% drop compared to the same period last year, while West Bengal saw a 13% decline. Things took a turn for the worse in May, with a 20% and 40% drop in production compared to 2023 in Assam and West Bengal, respectively. While West Bengal saw a 50% to 80% reduction in rainfall in major tea districts, Assam saw a 10% to 30% shortfall. It also means possible heavy monsoons with above-normal rainfall that further exacerbate the situation.

By Dan Bolton
Tea Research Institute Secretary Joydeep Phukan said the “hackathon marks a significant milestone in bringing technological innovation to one of India’s most vital industries. I’m proud to announce the successful conclusion of the first-ever tea Tech Brew National Hackathon, a groundbreaking event aimed at addressing the challenges faced by the Indian Tea Industry.”
Phukan said the event was organized “under the esteemed leadership of Chairperson Nayantara Palchoudhuri, Tocklai staff, and industry professionals who judged the competition.”
Team Orthodox
The winning students, Team Leader Pragyan Sen Deka, 23, and Pranjit Barman, 22, designed a drone-mounted hyperspectral imaging eye that roams tea gardens, searching for indications of pest infestations. Suspended below the drone is a smoke chamber that delivers natural fumigants that pests avoid.
Pragyan Sen Deka
Fumigating crops with low-hanging smoke is an ancient, effective, and non-chemical method of driving pests away. Winning team leader Pragyan Sen Deka describes how a modern “Spectro Smoke” generator heats ferns and grass with electrically controlled nichrome wire, producing a downward-driven column of smoke that rises to the underside of leaves and drives away pests like the tea mosquito, one of several insects that reduces tea yields in India by an estimated 147 million kilos a year.
“This innovation promises to transform how we approach pest control, ensuring healthier crops and a more sustainable future for tea plantations,” writes Phukan.
The Spectro Smoke Drone has 1000kv 10-inch propellers producing around 3500g peak thrust. Its max payload capacity is around 2kg. The drone is powered by a 4000mah lipo battery, which gives it a flight duration of 15-18 minutes with no payload. The transmitter is the 2.4GHz FS i6, with a range of 1.5 km.
Team Neuro Linga (second place)
The second prize goes to Team Neuro Linga at the PSG Institute of Technology and Applied Research in Coimbatore for designing an integrated weather and crop health monitoring system.
“Their innovative solution impressively combines AI and IoT to tackle pest control and crop health. Using sensors, cameras, and smart technologies, they’ve developed a comprehensive system that not only repels pests but also monitors and predicts pest outbreaks, ensuring healthier crops and a more sustainable future for the tea industry,” writes Phukan.
Team Doodle (third place)
Their innovative solution features a specialized RAG (retrieval augmented generation) model for tea pest detection, designed to minimize computational resources while delivering precise, domain-specific results. Utilizing a Phi2 model with 2 million parameters and an image classification model (ResNet), Team Doodle leverages research papers, and articles scraped via Jina AI to ensure accuracy and relevance. Additionally, minimal hardware is used to collect environmental data such as temperature and moisture, helping to prevent pest outbreaks with accurate and timely detection.
“Team Doodle’s approach represents a significant advancement in sustainable pest management for the tea industry. It combines cutting-edge AI with practical environmental monitoring,” writes Phukan.
Problems to Solve
Here is a list of problems students were asked to address:
Problem Statement 1: The tea industry faces significant challenges due to climate change, including water scarcity, temperature fluctuations, and soil degradation. Develop a technology-driven solution to help tea farmers adapt to changing climatic conditions, optimize water usage, and maintain soil health to ensure sustainable tea cultivation.
Problem Statement 2: Tea crops are vulnerable to various pests and diseases, which can devastate tea crops within a short period. Develop a predictive model using data analytics and machine learning to forecast outbreaks of pests and diseases, enabling pre-emptive action to protect crops and reduce the reliance on chemical pesticides.
Problem Statement 3: With climate change and changing weather patterns, the incidence of pest management has increased, with certain pests such as the Tea Mosquito Bug, Looper Caterpillar, and Green Thrips causing havoc in tea plantations. Develop technologies based on airwaves, sound waves, or biocontrol to control the outbreak of the Tea Mosquito Bug, Looper Caterpillar, and Green Thrips to showcase how it works in tea plantations.
Problem Statement 4: The tea plant Camellia sinensis is a wonder plant. Tea leaves are harvested to make various types of tea. The tea plant also produces tea seeds and flowers. Tea is high in various properties, such as antioxidants and flavonoids. Propose methods and technologies to convert tea into diversified products using tea leaves and waste using innovative technology.
Problem Statement 5: Tea is the second most consumed beverage after water globally. However, there is intense competition for tea as a beverage over other products. Some of the products sold as tea are not from the plant Camellia Sinensis. Develop technology-based solutions to promote tea amongst people from age 10 to 35 years, highlighting its many health benefits, which should be innovative and scalable to make tea the most sought-after drink. One may add non-technology-based suggestions to justify their technologies.

Tea Research Association – Tocklai Institute
To delve into the science and processes behind a good cuppa, visit the Tocklai Institute, the world’s largest and oldest tea research center (founded in 1911). The labs there research microorganisms that inhibit plant disease and promote growth. There is also a tea museum and model tea factory exhibiting the machines that turn leaves into teapot-ready tea.
History
The establishment of the Scientific Department of the Indian Tea Association (ITA) in 1900 marked the beginning of a new era of tea research in India. This was consolidated with the creation of the Tocklai Experimental Station in 1911.
The formation of the Tea Research Association (TRA) in 1964, with Tocklai at the center of all activities, further expanded the horizon of tea research to cover the entire Northeast India. Research on all aspects of tea cultivation and processing is carried out at the Tocklai Tea Research Institute, Jorhat, the world’s oldest and largest research station. Transfer of technology to its member estates is carried out through its advisory network covering 1,076 tea estates occupying 341,049 hectares (1,317 sq mi) of land spread over The South Bank, North Bank, Upper Assam, Cachar, Tripura, Dooars, Darjeeling and Terai. Tocklai has its regional R & D Centre at Nagrakata, West Bengal.
The organization undertakes basic and applied research on tea cultivation and processing in northeast India. A large chunk of the research work is done at Tocklai, while area-specific research for Dooars is carried out at NBRRDC, Nagrakata. Research on the pharmacological properties of black tea is carried out in collaboration with Kolkata and other institutes across India. The technologies developed through R&D activities are disseminated to the member gardens through a wide network of advisory personnel who conduct regular hands-on demonstrations and workshops.

Iran halts Indian tea imports, forcing growers and traders to find new markets.
Iran Halts Tea Imports From India
Iran, one of India’s big tea markets, has suddenly halted imports of tea and rice from India. No reason was given, although government officials have been quoted as saying this could be a retaliatory response as India stopped imports of kiwi and peaches from Iran. Another point raised was that Iran wanted India to restart buying oil. The Mint reported that Iran’s rice imports for April- September 2023 stood at $641.66 million, while tea imports for January- September 2023 stood at $66.39 million, valued second to the UAE. The tea bodies are waiting for Iran’s responses on the reasons for stopping imports.
NETA Asks For Ban On Six Pesticides
Representatives from the North Eastern Tea Association have submitted a memorandum to the state agriculture minister with an appeal to prohibit the stock, sale, and distribution of six pesticides – Cypermethrin, Acephate, Imidacloprid, Acetamiprid, Dinotefuran, and Fipronil. These pesticides are banned for tea, and the association said that testing of teas showed MRL ( maximum residue levels) residues indicating the use of these chemicals. The association said that these six pesticides contributed to much of the problems attached to the lack of food safety compliance.
Kangra Tea Seeks Government Intervention
The Kangra tea industry is awaiting some interventions from the state government to revive and promote their tea industry. The land under tea cultivation and crop have dropped significantly in recent years as it has been losing its viability. Three of the four government factories also remain closed. The tea association here has asked for greater support, especially in increasing the state’s tea tourism opportunities.
India’s first flush finishes with lower than average yield
First Flush 2024
The first harvest or flush has ended, and we are looking at how India fared this year. Across the country, a long, dry winter and late rains that fluctuate between too little and too much have affected crops. Overall, it appears that North India saw a decrease in yield by as much as 35-50% compared to the same period last year. Prices have not been commensurate.
Darjeeling experienced a long dry spell. The much-needed January rain did not show up this year. The problem of cheap tea imports from Nepal continues unchecked. Planters have been calling for checks on Nepal imports, better import testing, and protection of the Darjeeling heritage. This year saw more garden closures, which is expected to impact production, which saw one of its recent lows at 6.18 mn kilos last year.
In Sikkim, the first flush was delayed by 3-4 weeks due to late rains, which caused a late harvest. The second flush began earlier—by about two weeks—because of rising temperatures. Crop volume has also dropped here.
In Assam, production has dropped, as compared with last year, by close to 35%. March crop was down by 14mn kilos. Lack of rain has brought crop loss. The order to route 100% dust via auctions, while still not seen as beneficial by the planters, continues. However, prices are going up compared to last year. In the most recent Sale 21, two teas from Deckiajuli fetched upwards of Rs 600/ kilo – the BP grade sold for Rs 605 while PF grade sold for Rs 651.
Kangra experienced dry weather, and the crop was down. Production of the green tea, which is a highlight here, was delayed. Demand and prices are low.
South India has seen some better crops despite late rains and a hot summer. In March, the Nilgiris saw an increase of nearly 3 million kilos over 2023. Its traditional export markets of Iraq, Syria, Turkey, and CIS countries have been active, and Orthodox offerings have been doing well. However, currently, the region is seeing a long dry spell, which will impact crop production in the coming weeks.
Assam BLFs to close June 1st
The pesticide issue continues to plague Assam, and the Assam Bought Leaf Manufacturers Association, representing 110 factories, has said it will stop production on June 1st. The association states that buyers have refused their teas because of pesticide concerns. The Bought Leaf Factories say they have no control over pesticide use by small tea growers. Meanwhile, the Assam Chah Mazdoor Sangh has rallied the workers and held several protests. In Moran, workers gathered at the Bamunbari and Khowang gardens owned by Andrew Yule to protest against nonpayment of wages for several months. In Dibrugarh, protests were seen at the Basmatia Tea Estate.
Make Tea A National Drink
On May 21st, the North Bengal Tea Producers’ Welfare Association (NBTPWA) called for declaring tea India’s “national drink.” During the Tea Day celebrations in Siliguri, the association distributed 5,000 cups of tea. They seek to make tea attractive to youth and increase tea consumption.
The Bombay Burmah Tea Corporation’s Singampatti Group ceased operations on June 15th. The Group included the estates of Manjolai, Manimuttar, and Oothu, located in the Tirunelveli district in south India, at the southern tip of the Western Ghats. The reason for ceasing operations is the end of the 99-year land lease. The Forest Department issued an eviction notice with a phased plan for withdrawal. The BBTC company has been around for 150 years, and the Singampatti estates are renowned for their natural beauty and progressive efforts to maintain the area’s biodiversity. The Oothu Tea Estate has been completely organic since 1988, producing about 1mn kilos annually. In a LinkedIn post, the GM of Tea Operations, Asgar Hussain, was quoted as saying the company’s primary concern was for the future and welfare of its employees. “For a company like BBTC, which has conducted the tea business for the past 150 years with honesty and dedication, the stab is far deeper than we can comprehend. Oothu produced one of the finest Orthodox Organic with a Global customer base.”

Assam Gets Mobile Residue Testing Lab
Following the recent concerns about pesticide residue in tea and the need to address it, the Assam Bought Leaf Tea Manufacturer’s Association launched a state-of-the-art mobile residue testing laboratory earlier this week. This has been set up in collaboration with Eurofins Analytical Services India, which has the necessary instruments to test green tea leaves and made tea. The lab was inaugurated by Bimal Borah, Minister of State for Commerce and Public Enterprises.
New Tea Disease Detected In Assam
A team of scientists, led by Prof. Piyush Pandey from the Assam University in Silchar, has reported the discovery of a tea disease. The research was conducted over two years, and the Assam Tribune reported the story. The disease is a leaf necrosis caused by a fungus known as Lasiodiplodia theobromae, and it is reportedly similar to another fungal disease caused by Corticum. This new research is expected to help improve the treatment and control to save the leaves.
