Succulents are loved by many plant enthusiasts for their unique shapes and easy maintenance. However, they are also susceptible to pests and diseases, especially the invasion of white spot insects. This article will introduce in detail the reasons, symptoms, and control methods for white spot insects on succulents, helping you effectively deal with this problem.
Reasons for white spot insects on succulents1. Environmental factors: An overly humid and poorly ventilated growing environment for succulents can easily lead to the proliferation of white spot insects.
2. Soil factors: Soil that is too fertile or waterlogged, leading to poor root respiration, can easily cause white spot insects.
3. Improper maintenance: Overwatering and improper fertilization can lead to a weakened resistance in succulents, making them susceptible to white spot insects.
Symptoms of white spot insects on succulents1. White spots appear on the leaves, gradually expanding to form white patches.
2. The edges of the leaves turn yellow and curl.
3. The plant grows slowly or even dies.
Preventive measures for white spot insects on succulents1. Environmental adjustment: Maintain good ventilation and avoid keeping the plant in a humid environment for extended periods.
2. Soil treatment: Choose well-draining soil, avoid waterlogging, and change the soil regularly.
3. Water management: Water appropriately, avoid overwatering, and keep the soil slightly moist.
4. Chemical control: Spray insecticides such as pymetrozine, thiamethoxam, etc., every 7-10 days, with 2-3 consecutive sprays.
5. Biological control: Introduce natural enemies such as predatory mites to control the number of white spot insects.
Preventive measures1. Purchase healthy succulents and avoid buying plants with pests or diseases.
2. Regularly inspect the plants and deal with pests and diseases promptly.
3. Pay attention to maintenance skills to improve the plant's resistance.
White spot insects are one of the common diseases and pests of succulents. Understanding their causes, symptoms, and control methods can help us better maintain our succulents. In the process of maintenance, we should focus on environmental, soil, and water management, use insecticides properly, improve plant resistance, and thus effectively prevent the invasion of white spot insects.
