Using cultivation techniques to control diseases and pests in flowering plants is the most economical and fundamental preventive measure. The author now introduces the following 8 common measures for the reference of vegetable farmers.
Implementing crop rotation in the flower garden can effectively prevent diseases such as seedling collapse, damping-off, white rot, and wilt, as well as monophagous pests.
Reasonable planting: Flowering plants like Japanese quince should be avoided from planting together with cypress or other coniferous trees, as it can cause severe rust disease in Japanese quince and other flowering plants.
Resistant varieties: Choose and cultivate varieties with resistance to diseases and pests according to local conditions, especially for diseases and pests that are difficult to control or have no effective control methods, choosing and cultivating resistant varieties is more important.
Scientific fertilization: Scientific fertilization can adjust the nutritional status of flowering plants and enhance their resistance to diseases and pests. For example, using properly formulated soil for potted roses can reduce the occurrence of rose black spot disease.
Reasonable watering: Soil that is too wet and poor drainage is a cause of seedling collapse and the direct cause of root rot in flowering plants. Pathogens of cherry root cancer and jasmine white rot can be spread with running water, so attention should be paid to the direction of water flow during irrigation to prevent the spread of pathogens to nearby healthy plants. Timely watering to relieve drought can reduce the occurrence of rose powdery mildew.
Cultivating strong seedlings: Some diseases and pests are spread through propagation materials such as seeds, seedlings, bulbs, corms, scions, and cuttings. Therefore, healthy materials free from diseases and pests should be selected for seeding and propagation.
Thorough disinfection: Greenhouse disinfection often uses the fumigation method. Specific practice: Close the doors and windows in the evening, light the medicine for fumigation, and open the windows for ventilation the next day. For example, using 2-3 grams of 20% Fastkill smoke agent per 10 cubic meters, fumigate once every 7-10 days, and continue for 3 times. For soil disinfection of ground planted flowers, mix 70% pentachloronitrobenzene and 80% mancozeb wettable powder in equal amounts, sprinkle 8-10 grams per square meter and turn it into the ground, or use 50 milliliters of formalin diluted in 8-12 kilograms of water for irrigation.
Timely cleaning of the garden: By combining shaping and pruning of flowering plants, thoroughly and promptly remove diseased (fallen) leaves, diseased (insect) branches, and diseased plants, and集中销毁 them, which can achieve twice the result with half the effort in disease and pest control.
