Feed Flowers with Some Milk
When potted plant leaves are infested with stubborn pests such as red spiders and aphids, chemical pesticides not only pollute the environment but may also damage the plant roots. This article will reveal 7 types of ecological pest control solutions made from commonly used household items, achieving zero-pollution pest control through physical isolation and biological suffocation principles.
Milk Pest Control Method: Blocking Pests with Creamy Barrier
Analysis of Operational Principles
The casein in milk forms a dense mucous membrane when exposed to air, which can physically block the breathing pores of micro pests like red spiders. Experimental data show that whole milk has a pest-killing rate of up to 78%, especially suitable for ornamental plants like Chinese roses and jasmine that are prone to red spider infestations.
Four-Step Operation Guide
1. Use unspoiled whole milk, dilute it at a ratio of 1:5, and pour it into a pressurized spray bottle. 2. Focus on spraying the areas where eggs are concentrated on the back of the leaves, using about 200ml per square meter. 3. Avoid getting wet for 6 hours after treatment, allowing the milk film to air-dry naturally. 4. Repeat twice a week, along with ventilation, to eliminate over 90% of the larvae.
Hydro Jetting Method: Physically Removing Pest Groups
Equipment Modification Techniques
Using a showerhead with a water pressure of 0.3MPa to wash the back of the leaves, combined with a self-made potting soil protection board (EVA material with slot design), can prevent soil loss. For water-sensitive plants like succulents, it is recommended to use a misting mode and rinse in intervals.
Biopesticide Formula: Enhancing Pest Control Effect
Urine Wash Mixture Formula
Configure according to the ratio of 1g of dodecyl benzene sulfonate (main ingredient in laundry detergent): 4g of urea: 100ml of water, achieving double-killing by destroying the waxy layer of the pest's epidermis. Tests show that this formula has a 24-hour killing efficiency of 92% on cabbage worms.
Preparation of (Y-J) Solution
Feed Flowers with Some Milk
Collect 20 cigarette butts and soak them in 500ml of warm water, adding 5ml of palmitic acid soap to enhance adhesion. When the (Y-J) concentration is controlled at 0.08%, it can effectively repel pests without damaging the plant's stomata.
Environmental Control Strategy: Three-Dimensional Protection System
The efficiency of yellow sticky traps in killing adult pests is closely related to their hanging height: when placed 15cm above the plant's top, the capture rate of small black flies increases by 40%. Combined with laying diatomaceous earth on the surface of the potting soil, a three-dimensional protection net can be established.
By systematically implementing the three-phase plan of physical removal, biological control, and environmental control, and continuously observing the condition of the plant's new leaves, when the pest density decreases, preventive measures such as sprinkling cinnamon powder can be used to achieve ecological and sustainable pest control.
