How to Prevent and Control Diseases and Pests in Flower Cultivation
In home gardening, the prevention and control of diseases and pests is a key factor in determining plant health. This article systematically analyzes the characteristics of 8 common diseases and pests, and provides 3 eco-friendly management solutions to help flower lovers build a safe and green care system.
Guidelines for Preventing and Controlling Four Major Fungal Diseases
Identification and Control of Powdery Mildew
The typical symptom is white powdery substance covering both sides of the leaves, which can be controlled by improving ventilation and spraying baking soda solution. Varieties prone to infection, such as roses and chrysanthemums, need special protection. Regularly spraying 0.1% baking soda solution can achieve a control rate of over 80%.
Environmental Control for Grey Mold
The gray mold layer that appears in high humidity environments can be effectively prevented by sprinkling plant ash. Applying 300g of plant ash per square meter can not only suppress pathogens but also supplement potassium, making the stems of bulbous plants like tulips thicker and stronger.
Comprehensive Management Solutions for Four Types of Pests
Double Elimination Method for Scale Insects
How to Prevent and Control Diseases and Pests in Flower Cultivation
Combine the use of vinegar wipes and alcohol disinfection: first use a cotton ball soaked in 50ml of vinegar to remove the adults, then use 75% alcohol to treat the larvae. Perform this operation once a week for 3 weeks to completely eradicate.
Ecological Control of Red Spider Mites
Immediately rinse the back of the leaves with high-pressure water when the initial yellowing of the leaves occurs, and use yellow sticky traps to monitor pest populations. In severe cases, use biological pesticides such as matrine for eradication.
Three Golden Rules for Eco-friendly Pest Control
Physical Barrier Technology
Setting up a 40-mesh anti-insect net in the balcony planting area can block over 80% of adult moths from laying eggs. Combine this with blue boards to attract leafhoppers and red boards to trap thrips, creating a three-dimensional protection system.
Biological Regulation Strategy
Regularly apply EM菌 liquid to improve the soil microbial community and enhance the plant's own resistance. Applying a 1:500 diluted solution every 15 days can significantly reduce the incidence of bakanae disease.
By implementing triple protection measures of early prevention, accurate identification, and scientific management, combined with environmental management measures such as temperature and humidity control, an effective plant health ecosystem can be established. It is recommended to conduct systematic inspections monthly, and immediately address any eggs or lesions detected in the early stages to keep losses at a minimum.
