As a class one national protected plant, the Tiger Face Flower is highly favored by horticulture enthusiasts for its unique leaf vein patterns and beautiful flowers. However, in the process of actual maintenance, various pests pose constant threats. This article systematically sorts out the characteristics of the four common pests and scientific control methods to help you protect the precious plants and ensure their healthy growth.
Key Points for Leaf Beetle Control
The adult leaf beetle is 3-7mm long with a metallic luster shell. In addition to manually capturing the adults, it is recommended to spray the underside of the leaves with a 2.5% bromide ester emulsion 2000 times solution monthly, focusing on the high-incidence period from May to August. Establishing isolation zones can effectively prevent the spread of pests.
Comprehensive Management Plan for Nocturnal Moths
Given the nocturnal nature of nocturnal moths, it is recommended to use black light traps combined with biological control. Alternating the use of Bacillus thuringiensis (BT) formulations and 5% lambda-cyhalothrin can kill larvae and prevent resistance. Special attention should be paid to clearing water-logged areas promptly after rain.
Ecological Control Strategy for Snails
In addition to chemical control, beer traps can be set up: Bury shallow trays level with the ground, pour in beer to attract snails to drown. Planting驱避 plants like mint and rosemary can establish a biological protective barrier.
Comprehensive Control System for Slugs
Common pests and control methods of the Tiger Face Flower
Set up a diatomaceous earth isolation zone around the plants and wear rubber gloves when manually capturing slugs at night. Research shows that using bait agents containing metaldehyde, combined with spreading wood ash early in the morning, can reduce the damage rate by more than 90%.
By establishing pest monitoring logs, implementing crop rotation systems, and enhancing ventilation and lighting as preventive measures, combined with the targeted management plan provided in this article, the pest resistance of the Tiger Face Flower can be significantly improved. It is recommended to conduct special inspections every quarter, detect and address issues early to ensure the ecological safety of the rare plants.
