Nephrolepis Pests and Diseases Control Methods
As a popular choice for indoor ornamental foliage plants, Nephrolepis is loved for its unique feathery leaves and shade tolerance. This article systematically sorts out the key points of prevention and control and daily maintenance skills for common leaf blight, spider mites, and other pest problems during maintenance, helping growers create a healthy and lush fern landscape.
Nephrolepis Disease Control System
Comprehensive Control Plan for Leaf Blight
The symptoms of this condition include the spread of brown spots on the leaf edges, often accompanied by leaf curling and yellowing. It is recommended to adopt a three-level prevention and control approach: spray with 70% Mancozeb 800 times solution in the early stage, trim the diseased leaves in the middle stage, and alternate the use of Benomyl and Pyraclostrobin every 15 days in the later stage to prevent recurrence. Maintaining environmental humidity between 60%-70% can effectively inhibit the reproduction of pathogens.
Prevention Strategy for Fungal Root Rot
Additional notes on secondary diseases caused by waterlogging in the substrate are suggested. It is recommended to use a mixed substrate with 30% perlite and enhance drainage with ceramsite as a base. Immediately change the pot when black roots are found and treat with Metalaxyl 3000 times solution.
Nephrolepis Pest Control Plan
Ecological Control Method for Red Spider Mites
Considering the diurnal and nocturnal habits of this pest, it is recommended to alternate between chili water (boil 200g of小米辣 with 1L of water and cool) and matrine (1:1500). Focus on spraying the back of the leaves and rinsing the back of the leaves weekly can remove 90% of the eggs.
Biological Control Techniques for Aphids
Yellow sticky traps can be used for physical control during the seedling stage, and 10% Imidacloprid 2000 times solution can be used during the adult outbreak. Introducing natural enemies such as ladybirds can establish a long-term ecological control system, and planting mint and other pest-repellent plants around potted plants can be more effective.
Comprehensive Removal Plan for Scale Insects
Additional notes on the physical removal method using alcohol swabs are suggested. For persistent pest problems, it is recommended to use a combination of螺虫乙酯 with an organic silicon synergist, focusing on the areas where insects gather, such as leaf axils.
By establishing a management system of "prevention first, combination of prevention and control," along with temperature and humidity monitoring and reasonable fertilization, the resistance to pests and diseases of Nephrolepis can be significantly improved. It is recommended to apply water-soluble fertilizers containing humic acid monthly to enhance plant resistance, maintain good ventilation in the environment, and allow this green waterfall to remain vibrant for a long time.
