Summer Pests and Diseases Control Methods for Succulents
High temperatures and humidity in summer can easily trigger various pests and diseases in succulents, making mastering scientific control methods crucial for maintenance. This article systematically sorts out the identification features and response plans for 6 major diseases and 3 types of pests, along with intuitive illustrations to help growers diagnose accurately. At the end of the article, key maintenance points for the whole year are also provided.
Complete Analysis of Succulent Disease Control
Key Points for Stem Rot Disease Control
The typical symptom of succulent stem rot is dark brown rot at the base of the stem. It is recommended to apply a 800x solution of carbendazim monthly to prevent the disease. For infected plants, cut off the rotten part, soak in zineb solution for 15 minutes, and then plant in sterilized new soil after drying.
Response Strategy for (T-J) Disease
Brown spots on leaves expanding require vigilance for (T-J) disease. It is advisable to sprinkle wood ash on the pot surface every quarter. In the early stages of the disease, remove the affected leaves and alternate between Bordeaux mixture and tebuconazole to avoid resistance.
Emergency Treatment for Soft Rot Disease
Liquefaction and odor of the fleshy tissue are late-stage symptoms of soft rot. If leaves wilt, immediately stop watering and spray the entire plant with a 2000x solution of streptomycin, while also improving air circulation. It is recommended to set up a rain shelter during the rainy season.
Succulent Pest Management Solutions
Measures to Eradicate Scale Insects
Apply 75% alcohol on a cotton swab to kill white waxy insects. In case of large-scale outbreaks, use scale insect killer plus an organic silicon synergist, focusing on the backs of leaves and stem joints. Use phoxim granules for soil pretreatment when repotting in spring.
Integrated Control of Whitefly
Use yellow sticky traps to kill adults and apply insecticides to kill larvae. It is recommended to use a 2000x solution of imidacloprid weekly, along with covering the soil surface with fine river sand to prevent egg hatching.
Succulent Health Care System
Three Elements of Environmental Control
Maintaining a temperature difference of 8°C between day and night, air humidity below 60%, and at least 4 hours of direct sunlight per day can effectively enhance the disease resistance of succulents. It is suggested to use red and blue spectrum lights to adjust the intensity of light.
Scientific Watering Methodology
Use the "soak method" to water succulents, extending the interval to 10-15 days in summer, with the water temperature matching the room temperature. Adding Bacillus subtilis to the irrigation water can enhance root resistance.
By establishing a maintenance system focused on prevention and supplemented by control, along with regular inspections and growth records, the probability of pests and diseases can be reduced by over 80%. It is recommended to save this article with its illustrations to create a disease identification guide, promptly address any abnormalities, and ensure succulents safely survive the summer.
