Bonsai peanut disease prevention and treatment comprehensive guide, cause analysis and management skills

Common Causes of Potted Peanut Diseases and Control MethodsPotted peanuts, as one of the common plants in family gardening, not only beautify the home environment but also bring the joy of harvest to the family. During the cultivation process, potted peanuts may suffer from various diseases that affect their growth and yield. This article will provide a detailed analysis of the causes of potted peanut diseases and offer effective prevention and management techniques.Common Causes of Potted Peanut Diseases1. Pathogen InfectionCommon diseases of potted peanuts include peanut leaf spot and peanut rust, which are mostly caused by fungi. Pathogens overwinter in soil, diseased residues, and seeds, and infect peanut plants when conditions are favorable the following year.2. Environmental FactorsHigh temperature, high humidity, and poor ventilation are easy to cause potted peanuts to fall ill. Long-term use of the same fertilizer and high soil salinity can also increase the incidence of diseases.3. Improper MaintenanceImproper fertilization, excessive or insufficient watering, and insufficient lighting can lead to a decrease in the resistance of potted peanuts, making them prone to disease.Prevention and Control Methods for Potted Peanut Diseases1. Choose Disease-Resistant VarietiesWhen purchasing peanut seeds, choose varieties with strong disease resistance to reduce the risk of disease occurrence.2. Seed TreatmentBefore sowing, soak peanut seeds in a 50% carbendazim wettable powder solution (500 times) for 30 minutes to effectively kill pathogens.3. Soil DisinfectionUse 70% pentachloronitrobenzene wettable powder for soil disinfection to effectively prevent diseases transmitted by soil.4. Reasonable FertilizationApply organic and compound fertilizers, avoid the use of single fertilizers, maintain soil nutrient balance, and control the amount of fertilizer appropriately to prevent over-fertilization.5. Timely WateringKeep the soil moist but avoid waterlogging. Water in the morning or evening, avoiding midday high temperatures.6. Ventilation and LightEnhance ventilation, maintain air circulation, reduce humidity, adjust plant spacing appropriately, and improve lighting conditions.7. Timely Removal of Diseased Residues promptly remove and incinerate diseased leaves, branches, and other residues to prevent the spread of pathogens.8. Chemical ControlAt the early stage of the disease, apply pesticides such as a 50% carbendazim wettable powder solution (500 times) or a 70% thiophanate-methyl wettable powder solution (800 times) for spraying. Spray every 7-10 days, for a total of 2-3 times.The prevention and control of potted peanut diseases require the comprehensive use of various methods, including seed treatment, soil disinfection, reasonable fertilization, timely watering, ventilation and light, removal of diseased residues, and chemical control. Through scientific and reasonable maintenance, the probability of disease occurrence can be reduced, ensuring the healthy growth of potted peanuts.
