Common Diseases of Balcony Vegetables
With the popularity of balcony planting in cities, vegetable diseases have become a challenge for growers. This article provides high-definition symptom diagrams and control solutions for six common diseases to help you achieve scientific prevention and control.
Guide to Fungal Disease Control
Powdery Mildew: The White Spot Crisis on Leaves
Melon vegetables are prone to infection, with initial symptoms showing white powdery spots on the leaves, which later develop into net-like necrotic spots. It is recommended to alternate the use of 1000 times the concentration of carbendazim with 800 times the concentration of polyoxysulfuron, and enhancing lighting can improve the control effect.
(T-J) Disease: Fruit Killer
Common in pepper crops, the lesions show concentric rings. In addition to spraying polyoxysulfuron every 7 days, promptly removing diseased fruits can reduce the risk of secondary infections.
Strategies for Dealing with Environmental Diseases
Mildew: Poor Ventilation Hazard
Bean vegetables are prone to diseases in a confined environment. When using 700 times the concentration of mancozeb spray, it is necessary to simultaneously improve ventilation conditions, and it is recommended to open windows for 1 hour in the morning and evening to maintain air circulation.
Downy Mildew: Stubborn Disease
Common Diseases of Balcony Vegetables
Solanaceous crops commonly have black patches. Aluminum phosphide and Bordeaux mixture need to be used alternately, and foliar fertilization can enhance plant disease resistance.
Radical Solutions for Systemic Diseases
Blight: Tomato Killer
It is recommended to take preventive measures during the rainy season, and using 500 times the concentration of metalaxyl liquid combined with soil disinfection can enhance the control effect. Seriously diseased plants should be removed immediately.
Verticillium Wilt: Root System Crisis
When eggplant plants become dwarfed, the root irrigation method is more effective. 0.25 kg of liquid medicine needs to be slowly渗透 along the stem base, and combining with bio-fertilizers can improve the root environment.
Prevention is better than cure. It is recommended to implement a crop rotation system and regularly use EM bacteria solution to improve the soil. Diseased plants should be isolated in a timely manner, tools should be disinfected, and using yellow sticky traps to kill pests can reduce the incidence rate by 50%. Balcony gardeners should establish observation logs to record temperature and humidity changes and their association with disease occurrences.
