Accompanied by the morning mist, Wang Wanguo and his fellow villagers weed and pick tea in the tea garden, with the verdant and towering Wuzhishan not far away, its main peak appearing and disappearing in the clouds and fog.

The Wuzhishan large-leaf tea hidden in Hainan's tropical rainforest has long been a local calling card and a vivid testament to Wuzhishan's practice of "industrialization of ecology" and "ecologization of industry." Focusing on ecology to grow good tea, how is the quality of this "ecological tea" from Wuzhishan? Recently, reporters went "into the mountains" to investigate. Core Competitiveness Lies in Ecology Following the winding mountain road, the reporters arrived at the Wu Zhai Organic Ecological Tea Garden in Wuzhishan's Shuiman Township. What caught the eye were tea plants, ground cover film on the soil, and insect traps between the tea plants. Tea farmers picking tea in an organic tea garden in Wuzhishan.

Image Source: Chongqing Local Chronicles Office Nanchuan District is located in southern Chongqing, serving as a link between the main urban area of Chongqing and the towns in southeastern Yunnan and northern Guizhou. Within its borders lies Mount Jinfeng, covering an area of 13,000 square kilometers, recognized as a World Natural Heritage Site. It is known as “the Southern Buddhist Paradise,” “the First Mountain in Bashu,” “the Earth’s Biological Gene Bank,” and “the Chinese Herbal Repository.” The giant tea trees are scattered throughout the majestic and picturesque landscapes of Mount Jinfeng. Capitalizing on its superior geographical conditions and ecological environment, Nanchuan District has accelerated the development of modern mountainous characteristic and efficient agriculture in recent years. It has promoted agricultural products such as Chinese medicinal herbs, ancient tea trees, bamboo shoots, Nanchuan rice, and blueberries, collectively known as the "3+2" specialty agricultural products, with a total output value reaching 4 billion yuan. The district has been rated as a national model tea standardization demonstration zone and selected as one of the first districts to create a national agricultural modernization demonstration zone.

Tea grey blight is one of the most serious diseases affecting tea leaves, also known as tea shoot blight, primarily caused by the plant pathogenic fungus Pestalotiopsis sp.. This disease mainly affects mature and old leaves but can also infect young shoots, causing leaf withering, shedding, and even death of the entire plant, significantly impacting tea yield and quality. In recent years, there have been reports in China identifying a diversity of pathogens causing this disease, with multiple species within the genus Pestalotiopsis showing significant biological differences, making control challenging. Currently, chemical fungicides such as carbendazim, thiophanate-methyl, copper compounds, and others are primarily used for control, while biofungicides like pseudomonads, bacilli, and antibiotics (such as Wuyi mycin, camellia saponin, kasugamycin, and nisin) and extracts from approximately 30 plants, including Datura, are increasingly being applied. This article discusses the distribution and damage of tea grey blight, the biological characteristics of its causative agents, and epidemiological patterns, and proposes integrated control measures to provide guidance for practical disease management. I. Distribution and Damage Tea grey blight is widely distributed in tea-growing regions, including India and Japan, and occurs in all tea-producing areas in China. On young shoots, mature, and old leaves, the…
