The Digital Reform Leadership Group of Zhejiang Province issued the “Notification on the ‘Innovate in One Place, Share Province-wide' Account Book S0 for the Entire Province.” The “Xinchang Tea Guardian” from Xinchang County has been successfully selected, making it the first application from Xinchang County to be included in the province's “Innovate in One Place, Share Province-wide” initiative.
The “Xinchang Tea Guardian” is an application jointly developed by the Agricultural and Rural Affairs Bureau of Xinchang County, with the support and guidance of provincial and municipal agricultural and rural affairs departments, in collaboration with the Chinese Academy of Agricultural Sciences Tea Research Institute and Hangzhou Ruikun Technology Co., Ltd. It features “smart identification and scientific prevention and control,” providing a new intelligent recognition method and scientific prevention and control mechanism for the diagnosis and control of tea tree diseases and pests. Currently, the application is available on WeChat and Zhejiang Online, and has been listed in the provincial economic system's directory of local characteristic applications.
The “Xinchang Tea Guardian” realizes prediction and early warning of various tea tree diseases and pests, as well as code assignment and conversion, by creating a new model of online diagnosis throughout the process, building a new platform for 24/7 monitoring and early warning, and establishing a new mechanism for precise prevention and control along the entire chain. Through displaying red, yellow, and green “Tea Health Codes” representing different levels of prevention and control and breaking through barriers between agricultural supply stores and service providers, it forms a management loop of identification, early warning, and prevention and control, effectively ensuring the health and safety of tea gardens. Currently, the application has collected nearly 60,000 images in its disease and pest database, can identify 85 types of tea diseases, pests, and natural enemies, with an accuracy rate of 90.36%.
The “Xinchang Tea Guardian” is one of the application scenarios of the Xinchang tea industry brain and a significant manifestation of the digitalization progress of the entire tea industry chain in Xinchang County. It serves major scenes through a small entry point, solving major problems. To date, the application has generated 12,279 green codes, 633 yellow codes, and all related yellow code issues have been promptly converted to green codes through prevention and control measures, resolving over 10,000 tea disease and pest problems. It has achieved precise coverage of pesticide use in tea gardens, improved the quality and price of tea, reduced the use of pesticides in tea gardens by more than 20%, and increased the annual output value and average transaction price of tea by 2.45% and 3.16%, respectively.
2s Identification
For unknown tea tree diseases and pests, using the Tea Guardian mini-program to take a photo and identify them yields results in less than 2 seconds. Currently, the mini-program can identify 85 types of tea diseases and pests, including 11 diseases such as tea blister blight, tea cloud-patterned Leaf blight, tea anthracnose, tea white spot disease, and tea Bud blight; 58 pests such as tea geometrid, tea hairy caterpillar, tea aphid, tea tiny green leafhopper, and black scale; and 16 natural enemies such as Chrysoperla carnea and Coccinella septempunctata, with an accuracy rate of 90.36%.
Precise Prevention and Control
Through photographing and identifying tea tree diseases and pests, not only can the specific type be identified by the Tea Guardian mini-program, but it also assigns and converts codes based on the actual occurrence of that particular disease or pest within Xinchang County. This provides clear information about what disease or pest it is, where it occurs, its current level of harm, whether chemical control is needed, and which chemical should be used.
County-specific
The Tea Guardian mini-program, developed specifically for tea farmers in Xinchang County, currently has nearly 4,000 registered users. It has identified over 12,000 instances of tea tree diseases and pests. Through the collection, processing, and analysis of large amounts of data, it provides data support for agricultural authorities to understand the safety situation of tea gardens county-wide, enabling timely technical guidance and unified prevention and control, and strongly ensures the quality and safety of tea in the entire county.
