At present, the main theme of agricultural development has shifted from increasing production to green, and to promote green transformation of agriculture, then it is necessary to carry out production in a greener production mode and carry out plant protection with green plant protection. The promotion and application of information systems for the digital monitoring and early warning system for major pests and diseases of crops is a series of effective measures and actions actively taken by the current agricultural sector. Starting from scientific and technological means, it provides a strong support for agricultural agriculture to achieve green development and promotes green. Plant protection is solidly advanced. In the traditional plant protection work, the large-scale use of pesticides runs counter to the green development of modern agriculture. Therefore, the current agricultural field advocates drug reduction and control, and promotes green prevention and control and professional defense. Strengthening pest and disease monitoring and early warning is the most important part in green prevention and control and professional defense. After the application of specialized systems such as digital monitoring and early warning systems for major pests and diseases of crops, new breakthroughs were made in the automation and intelligentization of pest and disease monitoring and early warning, and the effects of prevention and control were generally improved, and the loss of pests was also reduced. At the same time, on the road of green development of agriculture, with accurate monitoring data as a guide, not only the agricultural drugs are more precise, but also the utilization rate of pesticides is improved, and the amount of chemical pesticides and application frequency are significantly reduced, and the agricultural ecological environment is obviously improved. The safety of agricultural products from the field to the "tip of the tongue". At present, the pace of transformation and upgrading of the agricultural plant protection industry has accelerated markedly. Pesticide reduction and efficiency have become the conscious actions of the industry. In the process of vigorously promoting the zero-growth action of pesticides and green plant protection, the digital monitoring and early warning system for major pests and diseases of crops has become the green plant protection in all regions. Strong support has injected vitality into the development of the industry, provided guarantees, and made outstanding contributions in agricultural production safety, agricultural product quality safety and ecological environment safety.
