Common insect pests and control methods
As a star variety in the meaty world, Teyulan is favored by gardening enthusiasts for its unique rolled leaf shape. However, during the maintenance process, pest problems often become invisible killers that hinder the healthy growth of plants. This paper systematically analyzes the hazard characteristics and scientific control plans for the two most common types of insect pests in Teyulian. Identification of pest characteristics of Teyulian Root-knot Nematode Control Program Root-knot Nematode forms white nodules by parasitic root systems. At the beginning, they are characterized by abnormal proliferation of fibrous roots. As the disease develops, typical rosary nodules can be seen. The victims showed symptoms such as growth stagnation and leaf chlorosis. In severe cases, the root system completely rotted, resulting in plant death. Comprehensive prevention and control strategies suggest the use of preventive soil treatment: use wireless soda (200g/mu) for soil disinfection before planting, or use JT compound bacteria (1kg mixed with soil and 10㎡) to improve the rhizosphere microecology. Millar emulsifiable concentrate (diluted 1500 times) can be used for root irrigation during the onset period, once a week for 3 consecutive weeks. Combined with the removal of infected roots, the treatment rate can be improved. Key points for the management of scale insects in Teyulian. Pest development rules Scale insects are highly contagious, and the probability of newly purchased plants carrying eggs is as high as 80%. In the early stages, larvae gather at the junction of leaf cores or rhizome and secrete honey dew to induce coal pollution disease. In severe cases, the larvae cover the entire plant and affect photosynthesis. The step-by-step management plan immediately isolates pests when discovered, using a two-pronged approach of physical removal (soft brush dipped in alcohol)+ chemical control (flower protection god diluted 800 times and sprayed). For stubborn pests, it is recommended to alternately use spirotetramate (muwangte) and flutrifenil (tefuli), combined with pre-embedding of tuchendan (3 g/pot) to establish long-term protection.
Pest prevention and control must adhere to the principle of "prevention first, treatment second." Regularly check the status of plants, keep the environment ventilated and transparent, high-temperature disinfection treatment of new soil before use, and use it with microbial inoculants for biological prevention and control, which can reduce the probability of pest occurrence by more than 80%. It is recommended to apply immunopotentiators such as seaweed essence every quarter to fundamentally improve Teyulan's anti-stress ability.
