Pest control for Prunus armandi in Huidong County is primarily affected by pine borers, which often cause discoloration of the leaves, leaf curling, or the formation of worm-like structures. These issues can significantly hinder tree growth and development. In addition, aphids secrete honeydew that stains the foliage, impairing the photosynthetic process and promoting the occurrence of sooty mold, which further damages the tree's health. To manage these pests effectively, it is recommended to use 5% Chuanbao No. 3 powder, or a diluted solution of 2.5% deltamethrin at a ratio of 5000 to 10000 times. Alternatively, insecticide oil No. 1 can be applied at a dilution of 150 to 500 times using ultra-low volume spraying methods. Regular monitoring and timely application of these treatments are essential to ensure the long-term health and vitality of Prunus armandi trees in the region.
