Groundbreaking potato virus detection technology emerges from China’s Sichuan province

In a significant advancement for agricultural technology, the Western (Chongqing) Science City has unveiled a groundbreaking Potato Seed Virus Nano Microsphere Immunoassay Rapid Diagnostic Kit.

As Yuting Chen reports in an article published on iChongqing.info, this innovative product, developed by Professor Lyu Dianqiu and his team, marks a major step forward in combating potato viruses, offering a swift and efficient solution that was previously lacking in the domestic market.

“We have spent four years independently developing this series of products,” said Professor Lyu Dianqiu, the chief expert of the Chongqing Potato Industry Technology System Innovation Team.

A Leap in Rapid Testing

The kit, a result of four years of dedicated research, utilizes cutting-edge biotechnology-derived immunological antibodies and innovative nano-microsphere materials. It stands out for its ability to deliver test results in a mere 5 minutes, a stark contrast to the slower traditional methods. This rapid diagnostic tool is not only simple to operate but also boasts high sensitivity, specificity, and cost-effectiveness, making it ideal for field testing.

Professor Lyu said the kit is simple to operate, highly sensitive, specific, and cost-effective, making it particularly suitable for field testing. His team has developed four types of virus nano-simulated enzyme immunoassay kits, including for PVX and PVY, which are ten times more sensitive than colloidal gold test strips.

Enhancing Potato Yield and Quality

Chongqing, known as China’s sixth-largest potato planting area, has historically faced challenges in ensuring the quality of seed potatoes due to the absence of effective detection technology. This has led to significant yield losses ranging from 10% to 20% or more. The introduction of this rapid diagnostic kit is set to revolutionize the industry by reducing disease occurrences and pesticide use, thereby promoting greener and healthier potato production.

The improved testing methods are expected to enhance the quality of Chongqing’s potato seeds, leading to increased yields and economic benefits.

Global Reach and Impact

The kit has already seen widespread adoption in various potato enterprises and scientific research institutes across several provinces in China. In a move that underscores its global significance, the team has supplied 1,000 test kits to countries involved in the Belt and Road Initiative, including Kazakhstan, Sri Lanka, and Bangladesh.

[Editor’s note: Over the past few decades, China has been on a mission to set up special economic zones throughout the country as a way to bolster trade and development. The Chengdu-Chongqing Twin City will promote closer cooperation and coordination between the two economically vibrant cities of Chengdu and Chongqing, both of which are in the west Chinese province of Sichuan. The Economic Circle spans an area of 185,000 square kilometers, with a population of over 96 million and a GDP of over RMB7 trillion (US$1 trillion). Further information on China Briefing.
