Diseases and insect pests have been plaguing the grape growing process. Scientific and rational pest control is an important task in vineyard management. At the annual conference of China's wine industry in 2011, Professor Wang Zhongyue of the Grape Diseases and Pest Research Center of the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences and the National Institute of Disease Control of Plant Diseases and Pests of the National Grape Industry Technology System discussed this issue with everyone. Grape pests and diseases may cause damages such as death of vines, loss of yield (or lack of harvest), and deterioration of quality. Failure to do so will only increase production costs, and may even result in large-scale destruction of gardens or a situation where it is not suitable to continue growing grapes in large areas. The entire grape industry and the winemaking industry have been hit hard. For example, France discovered grape phylloxera in 1868. In 1877, 287,500 hectares of vineyards were destroyed and 278,800 hectares were infested during the nine years. This is equivalent to the destruction of more than 40% of French vineyards. The economic efficiency has been reduced by about half, the industry has continued to slump, and the French economy has suffered heavy losses. The incident also caused a third of the population of France to leave their home country and immigrate to countries such as Algeria and the United States. Plants and diseases and pests that live on plants are mutually restrictive and coevolving. In the history of evolution in nature, there were diseases and pests on plants before humans appeared. For example, downy mildew and phylloxera on grapes are all older than humans. After the advent of mankind, because of the need to survive, live, and reproduce, anything that has a detrimental effect on people becomes the enemy of mankind. For example, humans need food and fruit, so plant diseases and insect pests that affect the growth of food and fruits are the enemies of humans because they have to fight against humans for food and fruits. However, with the increasing space for human activities, frequent contacts, and changes in the environment, new situations and threats are constantly emerging, and pests and diseases are increasingly difficult to control. There are three main reasons for this: Single planting of a crop When a crop begins to be cultivated in a large area, the frequency of pests and diseases will gradually increase as the area of ​​the crop expands, and the hazards will become more serious. For example, after more than 50 years of development, natural rubber has become the largest biological industry in Xishuangbanna. No matter what the scale of planting, employees, or economic output are, other crops cannot match. However, with the continuous expansion of natural rubber planting areas, the frequency of pests and diseases has gradually increased, and its hazards have gradually expanded. The occurrence and prevalence of cyanobacterial deciduous disease in rubber trees resulted in deciduous trees, shoots and shoots withered, young trees delaying cutting, and aging tree latex production reduced by more than 20-40%, causing significant economic losses to the natural rubber industry. Increased human activity leads to the spread of dangerous pests and diseases Due to the plant diseases and insect pests and local plants there is a mutual restrictive relationship. Therefore, in general, plants of origin are resistant to pests and diseases, or are restricted by ecological factors such as natural enemies in the country of origin, and generally do not occur severely. If pests and diseases are introduced into new areas, they will cause serious harm because of the lack of resistance, natural enemies or other ecological factors. For example, after Columbus discovered the New World in the Americas, the missionaries began to bring European grapes to plants in Florida and other places in eastern North America. However, after long-term cultivation practices, they all ended in failure. This is mainly due to the fact that Eurasian grapes cannot tolerate the winter cold temperatures, soil conditions, and serious diseases and phylloxera in new areas. Subsequently, they began to try to use the United States to replant the local grape varieties or to bring American varieties back to Europe. In the process of European grapes introduced into Europe, the powdery mildew originating in North America was also introduced into Europe and became popular. It became one of the most important grape diseases in Europe and caused serious trouble for the European grape industry. Grape growers speculated that American grapevines are resistant to powdery mildew. In order to prevent powdery mildew, they once again introduced American grape varieties and tragically brought grape phylloxera into Europe. Planting of fine varieties results in genetic variation of pests and diseases, which makes the periodic harm of diseases and pests worse. Because of the co-evolutionary relationship between plant diseases and insect pests and plants, the genetic characteristics of pests and diseases are changing, and the disease resistance of planted crops is also required to change accordingly. Therefore, disease-resistant varieties cannot be simply used to prevent and control pests and diseases. This change in pests and diseases will increase the difficulty of pest control. Therefore, the task of pest control will become more and more arduous. According to rough statistics, there are currently about 50 fungal diseases that harm China's grapes, 1 bacterial disease, more than 30 virus types, and more than 120 insect pests (including red spiders). The most important pests and diseases are downy mildew, anthrax, white rot, acne, powdery mildew, gray mold, acid rot, leaf blast, lycopene, and felt disease. Pesticides, as a substance for controlling pests and diseases or regulating the growth of plants, are the key to the prevention and control of pests and diseases in vineyards. The use of pesticides is conditional and regulated, and should not be abused blindly. The use of pesticides is not a problem, but it must be controlled and follows the principles of science, rationality and accuracy. Under the standardized prevention and control system of grape pests and diseases, we must pay attention to improving the efficiency of pesticide use, select the right equipment and operate it correctly, adopt scientific methods of application, and atomize pesticides. In addition, in the prevention and control of grape pests and diseases, attention should be paid to those newly developed grape growing areas, including those emerging production areas and newly-built bases. In these places, pests and diseases will have a buffer period of about five years and will not occur very seriously. However, five years later, the pests and diseases in these grape growing areas may enter normal conditions. The alternation of emerging pests and pests and the use of pesticides also require special attention from grape growing managers. which is the most accurate and difficult to be duplicated. The human eye is consists of sclera, iris, pupil. The iris is located between the black pupil and white sclera annular section. It contains a lot of overlap characteristics, such as sports, filaments, coronary, strips and fossaes. These characteristics are unique for each person. The Iris Recognition technology is to identify each person. The iris recognition technology is to identify each person by comparing the similarity between iris image characteristics.this is the key to open the lock after verifying the iris successfully .and the lock use iris technology is very high security .
