What are the pests and diseases of potted flowers
Spring is the peak season for the growth of potted flowers and a period of high incidence of pests and diseases. Mastering the identification and control methods of common pests and diseases can not only protect the healthy growth of plants, but also extend the viewing cycle. This paper systematically analyzes the characteristics of 8 typical pests and diseases and provides professional solutions. Guidelines for the Prevention and Control of Common Diseases Treatment of Cold Damage in Late Spring Temperature fluctuations in the Yangtze River Basin in March can easily lead to frostbite of new buds. The damage rate of tropical plants such as Bailuan and Clivia reaches 80%. It is recommended to adopt the "progressive method of leaving the room": keep doors and windows open day and night before Qingming Festival, cooperate with fans to circulate air, and move them out after the average daily temperature stabilizes to 15℃. Comprehensive prevention and control of powdery mildew requires a "three-stage control" of susceptible plants such as rose and crape myrtle: sulfur fumigation (3g/m³) during the germination period, spraying baking soda solution (5% concentration) during the leaf expansion period, and alternating use of phenoxyconazole during the bud emergence period. The best effect is achieved by spraying medoxazole and myclofenazole at an interval of 10 days. (T-J) Disease system management What are the pests and diseases of potted flowers
Camellia, orchids, etc. need to establish a "prevention-treatment" system: keep the plant spacing above 30cm, and use siphon water supply to avoid wetting of the leaves. In the early stage of the disease, use (T-J) Fumei + carbendazim compound preparation, combined with potassium dihydrogen phosphate foliar fertilizer to improve resistance. Key technologies for pest management: Physical elimination of scale shells and insects adopts differential treatment for different insect bodies: waxy scale shells are dissolved with alcohol cotton sheets, and shield scales are glued away with tape. The "three-step killing method" is recommended: first physical removal → then spraying mineral oil → finally embedding dinotefuran granules in the roots. Establish a biological control system for ecological control of aphids: place 2 ladybug larvae per square meter, and hang yellow sticky insect boards (20cm from the basin surface). In severe cases, use directional spraying of (Y-J) pesticides, and pay attention to avoiding the flowering period to protect pollinating insects. The comprehensive prevention and control of whiteflies implements the "environmental regulation + biological control" model: the supplementary light at night is extended to 4 hours to break the whiteflies 'biological clock, and the beautiful aphid wasps are released at the same time (bee-to-insect ratio 1:30). For chemical control, imidacloprid and spirotetramat were used alternately, and the focus was on spraying the back area of the leaves.
Scientific prevention and control must follow the principle of "prevention first, comprehensive prevention and control." It is recommended to establish a maintenance log to record changes in temperature and humidity and the occurrence of pests and diseases, and use soil detectors to maintain the EC value between 1-2mS/cm. Regularly rotate the direction of the potted plant to ensure balanced light and fundamentally improve the plant's ability to resist diseases and pests.
