The U.S. grapevine is a famous new breed in the current grape variety. The principle of its pest control is: "prevention as the main, comprehensive prevention and control." Chemical control should be given to the right medicine, timely medication; pay attention to the rotation of the use of drugs and reasonable mix; the concentration of each pesticide, the number of uses each year and the safety interval (the last time the distance between the use of fruit harvest time) should be officially The methods prescribed in GB18321.1-8321.7 Guidelines for the Fair Use of Pesticides are published. Detailed and accurate records should be made for each pest control. At present, there are more than 30 kinds of diseases that harm the production of grapefruit. More than 20 species of insect pests. Among them, fungal diseases are the most prominent. The main fungal diseases are grape black spot disease, white rot disease, powdery mildew, anthrax, downy mildew, gray mold, brown spot, and brown shaft browning. Except for grape virus disease, it is also a serious disease on grapes. 1. In the pollution-free production of grapes, the use of highly toxic, highly toxic, high residue and “three causes†(teratogenic, carcinogenic, mutagenic) and “three certificates†(a pesticide registration certificate, production license) are strictly prohibited , Production batch No.) Pesticides Pesticides that are restricted from use in the production of pollution: refers to some pesticides that can be applied within the prescribed scope according to the prescribed methods. However, there are strict regulations on the concentration of use, the number of uses, and the interval of use. Mainly include: dimethoate, phoxim, trichlorfon, cypermethrin, chlorothalonil, metalaxyl, carbendazim, procymidone, acetaminophen, triadimefon, cobo, penc etc. Each of the above pesticides is generally applied only once per pesticide in a growing season. In addition, it must be used strictly in accordance with the requirements of pollution-free drugs. 2. Pollution-free prevention and control of major pests and diseases (1) Grape black spot disease. Prevention of the disease must be sprayed as soon as possible to protect the young plants on the branches and young fruit. Commonly used preventive agents are Bordeaux fluid, Penco, Trichoderma and Cobo. If there is a slight occurrence of black pox, then we should immediately use Fuxing, Subaoli, and Mildew, etc. for prevention and treatment. At the same time, the diseased leaf shoots and young ears should be promptly removed, destroyed, and disinfected in the field. (2) Grape downy mildew. It is a fungal disease that is common and extremely harmful in grape production. In addition to the strengthening of agricultural control, the main protective agents used to prevent the disease are Bordeaux mixture, Cobo, spray and these drugs are mainly used before the onset. However, if the disease occurs, therapeutic agents should be used for prevention and treatment. The most important drugs are DuPont Cocoa, Anc, Cureamide, Milconin, and Alpha-Phosphate and Pencoc. The combined use of B-Al2O3 and Spike has a good therapeutic effect. The specific drug concentration and method can be determined according to the degree of disease occurrence and the active ingredient content of the medicament. (3) White rot of grapes. The occurrence of this disease has a direct relationship with field management and the formation of wounds on plants. Therefore, it is an important prevention and control measure to increase the height of the grape frame, improve the ventilation and light transmission conditions, and prevent all kinds of natural and man-made injuries. In the prevention and treatment of drugs, before the onset of infection, Kebo, Penke, and Fumei have good preventive effects. If it is found that white rot begins to occur, it should be treated with drugs such as Fuxing and Thiophanate. (4) Anthracnose in grapes. It is a disease that seriously damages the grape fruit, which is also known as late rot. In addition to prevention and control of anthrax as early as bagging, drug control is very important. Especially early spraying of the resulting mother tree is very important. The commonly used preventive agents are chlorothalonil, tetromycin, cobob, and anthrax. In the early stage of disease, two new pesticides, chlorpromazine and bromocresol, are used to treat the disease. (5) Grape gray mold. It is a disease with serious infections such as grapes and grapes. It has three incidence periods in one year, namely before and after anthesis, before and after maturation, and during storage, causing great harm. Commonly used prophylactics are: Praxamol, Cobo, Formamide, Carbendazim, and Thiophanate. Before the ear bagging and storage before storage, must be treated with drugs. (6) Grape virus disease. It is a grape disease that is currently being watched by all countries in the world. There is no effective method for the treatment of this disease worldwide. Therefore, the prevention of virus infection should be planted with virus-free seedlings and soil not grown with grapes. Virus-free cultivation of grapes is a major development direction in the future. (7) Grape pests. Grape vines are also called grape felt disease. The key to prevention and control is spraying lime sulfur before germination, and dimethoate can be used to prevent and control them in the growing season. Ye Hao can be used to prevent and control a long time spirit, enemy and help fear. Lumbricus can be treated with TP. Scarabs mainly harm fruits that are about to mature. Therefore, ear bags can be effectively prevented. At the same time, it can be sprayed with trichlorfon and other agents during the adult stage. However, it must be noted that pesticides should be used with caution in the month prior to fruit picking to prevent pollution.
