This is the location of the succulent
Early summer is the peak growing season for succulents, but the seemingly naive leaf folds hide dangers. Many flower enthusiasts find that the plants suddenly wilt, unaware that battles against pests are raging in these hidden corners. Which parts are most likely to breed pests? How to effectively stop the spread of pest infestations?
Accurate prevention and control of the four major pests of succulents
Scale insects: The white threat in the leaf crevices
In the dew-damp axils of the leaves, tiny white scale insects are using their刺吸式口器 to absorb sap. This type of pest has super reproductive power, with a single female capable of laying 400 eggs, completing a generation in just 7 days. When using the medical alcohol dot painting method, be sure to use a cotton swab to rotate 360° to clean the leaf heart, destroying its waxy protective layer.
Red蜘蛛: The invisible killer on the back of the leaves
This is the location of the succulent
When star-shaped chlorosis spots appear on the leaves, immediately check the back of the leaves for spider webs. This type of mite reproduces faster when the humidity is less than 60%, and the "dry-wet alternating" control method can be adopted: rinse the back of the leaves with 28℃ warm water in the morning and spray with azoxystrobin suspension in the evening to disrupt its growth cycle.
Whiteflies: The derived disaster of poor ventilation
Honeydew-induced sooty mold is more dangerous than the pest itself. It is recommended to add bamboo charcoal particles when repotting, as their porous structure can absorb secretions. For infected plants, use a high-pressure atomizer to spray sophoraflavescens alkaline solution, with the diameter of the medicinal mist droplets controlled between 50-80 micrometers.
Small black flies: The breeding machine in the deep soil
The larvae of these dipterous insects can consume new roots within 72 hours. To control them, create a diatomite mulch layer, whose sharp crystals can physically kill the adults. In conjunction with the use of Bacillus thuringiensis BTI granules, the life cycle is blocked in two ways.
