Tomato Disease Prevention and Control The main diseases of tomato include early blight, late blight, wilt disease, gray mold, bacterial wilt, canker, leaf mold, and brown spot. With the development of solar greenhouses and the fixed cultivation of plastic greenhouses, soil-borne diseases and gas-borne diseases of tomatoes have been developed. The most serious disease in many areas of open tomatoes is viral disease. Rainy nights, epidemics, bovine diseases, and gray molds have become popular. There are many kinds of tomato diseases, and several diseases occur at the same time in the same place. Comprehensive prevention and control are required.
1. Change seedling bed to new soil, or treat bed soil with the green sterilizer No. 8 soil disinfectant drug (see the prevention and cure of vegetable seedling disease in the disinfection method), or adopt the ground heat nursery and plastic seedling nursery to reduce the root damage and shorten the nursery period (viruses Disease, Fusarium wilt, Canker disease, Bacterial wilt.
2. The disease-free strains are seeded, or the seeds are soaked in hot scald or seeded with chemicals such as Greenhenge No.1.
3. The implementation of non-solanum crop rotation for more than 3 years.
4. Protect tomatoes in the early spring to increase the temperature and temperature of the land. After the flowering results, strengthen the ventilation, reduce the humidity, and reduce the condensation (grey mildew, late blight, blight, ulcer disease, and leaf mold).
5. Autumn tomato nursery is carried out in rain-proof, insect-proof and shading protected areas (virus disease, late blight, virus disease, etc.).
6. Autumn greenhouse tomato to increase the amount of ventilation, reduce the temperature and humidity (leaf mold, early blight, blight).
7. Focus on the prevention and treatment of drugs In the prevention and early onset of the disease, it is possible to spray Botrytis cinerea and leaf mold with 800 to 1000 times of green hengheng No. For diseases such as stem blight, leaf, and fruit diseases such as late blight, it can be used to spray 800 to 1000 times of water on Green II, which can cure a variety of diseases. For bacterial wilt, soft rot. Virus disease and other available Green Hunter No. 6 (sterilization king) 1000 ~ 1500 times plus hi every spring, it is best to use Nornal grams of 8 grams of water 30 kg plus green wind 95 '(nucleotide) 30 Jin spray control Better results.
