Pest Diagnosis Atlas of Luli Hall
Three Stages of Whitefly Infestation Characteristics
In the early stage, semi-transparent nymphs can be seen聚集 on the back of the leaves, in the middle stage, sticky secretions appear on the leaf surface, and in the later stage, black mold spots accompany sooty mold disease. This pest has a breeding cycle of only 7-10 days and requires timely interruption of the transmission chain.
Comprehensive Whitefly Control Plan
In addition to spraying 2000 times the solution of氧化乐果, neem extract biological agents can be alternately sprayed. In severe infections, a three-step method is used: first, physical flushing; then, chemical spraying; finally, hanging yellow boards to attract adult insects.
Scale Insect Control System
Analysis of Hidden Damage by Scale Insects
This pest is good at using waxen shells for camouflage, often hiding in the leaf axils. It continuously consumes plant nutrients through piercing-sucking mouthparts, leading to chronic damage such as leaf discoloration and growth stagnation.
Stereoscopic Control Strategy
Physical removal combined with chemical control: after brushing, wipe the insect bodies with 75% alcohol. It is recommended to use thiamethoxam, a strong systemic insecticide, combined with root application of small white medicine to form long-term protection.
Golden Rules for Pest Prevention
Environmental Control Points
Maintain 50%-60% air humidity and ensure a day-night temperature difference > 8°C. Every quarter, apply a 800 times solution of carbendazim to the roots to enhance plant resilience.
Daily Maintenance No-fly Zone
Avoid excessive nitrogen fertilizer that causes the leaves to be too tender and prohibit the use of uncomposted organic fertilizer. Regularly rotate the flowerpot to ensure even lighting and clear dead leaves to block the overwintering sites of insect eggs.
By establishing a protection system that integrates pest monitoring, precise treatment, and environmental control, the incidence of pests in Luli Hall can be effectively reduced. It is recommended to check the back of the leaves monthly and combine seasonal preventive medication to keep the plants in the best ornamental state.
