Pest and Control Methods of Plants with Red Flowers at the Top, Introducing Four Common Pest Control Methods
When raising plants with red flowers at the top, pests can be a troublesome issue. Common pests include scale insects, red spiders, bagworms, and oblique-striped noctuids. If the condition is not severe, the leaves can be directly cleaned and disinfected; if the disease is serious, chemical treatment needs to be sprayed. The editor has compiled the pest and control methods for plants with red flowers at the top, which everyone should pay more attention to.
1. Scale Insects
Scale insects are small parasitic insects that do not move much or are completely attached to the plants. They cause the leaves of plants with red flowers at the top to turn yellow, the branches to wither, and the plant to become weak, and they can easily trigger sooty mold.
Control Methods:
Firstly, improve the ventilation environment and promptly clean the areas damaged by scale insects. If the scale insects are severe, in winter, you can spray once with a 10-15 times pine resin mixture or a 40-50 times machine oil emulsion to eliminate the overwintering female insects.2. Red Spiders
Red spiders are relatively small and common in cactus cultivation. They usually pierce the leaves of plants with red flowers at the top with their mouthparts to suck the sap, damaging the chlorophyll, causing the leaves to show gray-yellow spots or patches, turn yellow, fall off, or even completely defoliate.
Solutions:
Ensure good ventilation and keep the air moist by spraying water. When the damage is slight, you can remove the affected leaves. If the pest infestation is severe, you can add 8 drops of trichlorfon or dimethoate and make sure to spray the backs of the leaves.3. Bagworms
Bagworms mainly harm the leaves of plants with red flowers at the top, usually eating away the leaf flesh, leaving only a transparent lower epidermis, which dries up and falls off, turning into holes or gaps or breaks. This eventually leads to the withering of branches or the entire plant.
Solutions:
In autumn and winter, combine pruning with manual removal of bags to eliminate overwintering mature larvae. Chemicals such as trichlorfon, dichlorvos, dimethoate, malathion, and fenitrothion can be used for spraying.4. Oblique-Striped Noctuids
Oblique-striped noctuids mainly harm the flowers of plants with red flowers at the top, feeding on petals, stamens, and pistils. They usually hide in the potting soil or the bottom of the pot during the day and come out to feed in the evening, but they may feed during the day in cloudy and rainy weather.
Solutions:
When pest problems with oblique-striped noctuids are found, promptly spray with chemical treatment. For example, using a miticide black killer at a concentration of 800-1500 times, with the timing of spraying in the morning and evening, ensuring sufficient water for the spray, and the base of the plant and ground should be sprayed as well, and the chemicals should be alternated.The above is the introduction to the pests and control methods of plants with red flowers at the top and the related explanation of four common pest control methods, hoping to bring a little help to your life!
