Abstract:  Chemical control is an important part of the comprehensive prevention and control of tea tree pests and diseases. It has the advantage of rapid and effective prevention and control when the pests and diseases are sudden or explosive. The surface of tea leaves is hydrophilic, and the constant application of pesticides can cause problems such as excessive pesticide residues in tea and damage to the ecological environment. Realizing reduced pesticide application of tea trees is an effective method to reduce pesticide residues in tea. The biological characteristics of tea trees, the predictive diagnosis and control methods of tea tree diseases and insect pests, tea tree protection machinery, and pesticide application technology were systematically reviewed. It was emphasized that improving the effective utilization of pesticides in lowvolume spraying of tea tree was the key to reducing tea tree application. In response to the current problems of complex ground conditions and low pesticide utilization in tea gardens, research recommendations on tea tree pests and diseases application technology and equipment had been put forward from six aspects, including lowvolume profiling sprayers, tea tree pests and diseases spray decisionmaking, and intelligent terminals. It was pointed out that low quantification, precision, and intelligence were the future development direction of tea tree protection spray machinery and application technology.
