How to completely eliminate multi-meat scale insects
When white cotton-like insect bodies appear in the gaps between the leaves of multi-meat plants, it indicates that scale insects have silently invaded. This stubborn pest that sucks plant sap will cause the plant to wither if not dealt with in time. This article systematically compiles 5 scientific pest control solutions, combining physical control and chemical intervention to help you protect the health of your multi-meat plants.
Five professional pest control solutions
Chemical control: accurate medication strategy
Professional insecticides such as Flower Protector and Rapid Killer need to be diluted at a ratio of 1:800-1000, and sprayed evenly on the back of leaves and the junction of stems with a atomizing spray bottle. It is recommended to apply the medicine in the early morning and place it in a well-ventilated area after application. It is necessary to alternate the use of dinotefuran and imidacloprid to avoid using the same medicine for 3 consecutive times.
Physical fumigation: emergency treatment at home
Put a transparent sealed bag over the plant and place a lit mugwort mosquito coil inside, leaving a 2cm ventilation gap. Fumigate for 30 minutes for medium-sized potted plants, and extend to 45 minutes for large plants. This method can effectively kill 90% of adult insects but is ineffective against eggs and requires combination with other measures.
Mechanical pest removal: key to early prevention and control
Use a 000 oil painting brush dipped in 75% alcohol to kill visible insects, and use a magnifying glass to assist in checking the leaf axils. Conduct a comprehensive check twice a week for a month. Focus on cleaning the creases of new leaves, which is the main egg-laying area for scale insects.
Root protection: application of systemic insecticides
Mix dinotefuran (small white medicine) with the matrix at a ratio of 3g/liter of soil, with the effect lasting for 45-60 days. Additional medication is needed during the rainy season, and avoid watering within 5 days after application. Combining with diatomaceous earth mulch can enhance the protective effect, forming a dual physical and chemical barrier.
Completely change the soil: severe treatment plan
Rinse the roots under running water for 2 hours after removing from the pot, trim the necrotic roots, and soak in carbendazim. The new soil needs to be sterilized at 121℃ high pressure for 30 minutes, and it is recommended to use red jade soil mixed with rice husk charcoal (7:3 ratio). After potting, maintain an environmental humidity of ≤40% during the seedling establishment period to block the hatching conditions of insect eggs.
When using comprehensive prevention and control solutions, it is recommended to follow the principle of 'physical pest removal leading the way, chemical control as a supplement, and environmental regulation solidifying results'. Maintain a day and night temperature difference of >8℃ during daily maintenance, and use garlic extract (1:50) for prevention every month, which can reduce the recurrence probability by 85%. Remember, continuous observation is the key to radically eliminating scale insects.
