The Latest Methods for Preventing and Treating Common Summer Succulent Pests and Diseases
Disease Prevention and Treatment
Stem Rot
Stem rot mainly damages the stem base of succulents. When the disease occurs, a dark brown color develops at the affected area, gradually causing the plant's stems and branches to rot and soften, and in severe cases, it can cause the entire plant to die.
Prevention and treatment methods: Stem rot is mostly caused by fungi, so during daily care, pay close attention to ventilation and carry out reasonable water and fertilizer management. The growing medium is best sterilized before use. If symptoms appear, spray carbendazim or amobam for prevention and treatment.
Anthracnose
Anthracnose mainly damages the fleshy leaves of succulents. When the disease occurs, brown leaf spots appear, and as the condition worsens, the lesions gradually expand and turn brown. In severe cases, it can lead to leaf drop.
Prevention and treatment methods: When lesions are found, promptly remove the diseased branches and leaves, pay attention to keeping the pot soil clean during daily care, and carry out sterilization work in a timely manner. After symptoms are found, spray carbendazim or Bordeaux mixture and other medications for timely prevention and treatment.
Soft Rot
In the early stages of soft rot, the fleshy stems and leaves appear weak and limp. Once the disease becomes severe, a sticky wet rot appears on the surface of the plant and gives off an unpleasant odor.
Prevention and treatment methods: Pay close attention to giving succulents ventilation, while controlling watering to avoid the pot soil becoming too wet. In the early stages of symptoms, carry out medication treatment as soon as possible, spraying streptomycin or Bordeaux mixture to treat and control it.
Phytophthora Blight
Phytophthora blight mainly damages the roots and stems of succulents. Dark brown water-soaked lesions appear at the affected area, and sometimes a white mold layer also appears.
Prevention and treatment methods: During the succulent care process, pay attention to keeping the pot soil clean. The growing medium is best sterilized and disinfected before use. Spraying medications such as phosethyl-Al copper can effectively prevent and treat it.
Black Spot
Black spot mostly damages the fleshy leaves of succulents, producing black dot-like spots on the leaves, and in severe cases, rot can occur.
Prevention and treatment methods: After discovery, carry out medication treatment promptly. Spray carbendazim or chlorothalonil for prevention and treatment, and after a period of time, the condition can be well controlled.
Sooty Mold
When sooty mold occurs, it must be dealt with promptly, because sooty mold is highly infectious. It is mostly caused by the stuffy, hot, and humid growing environment of succulents.
Prevention and treatment methods: During daily care, pay attention to ventilation and to the watering ratio. You can appropriately dilute and spray alcohol, or choose carbendazim for spraying.
Pest Prevention and Treatment
Scale insects mainly damage the stems and leaves of succulents. They live by sucking the plant's sap, often causing succulents to show symptoms of leaf drop and yellowing.
Prevention and treatment methods: Rinse the plant with water to remove the pests, or when pests are found, promptly replace the pot soil and clean the succulent leaves.
Whiteflies
Whitefly larvae parasitize inside the plant and suck its sap. The secretions of whiteflies can induce sooty mold, having an extremely bad effect on the health of succulents.
Prevention and treatment methods: Provide a ventilated environment, and use insecticides such as malathion for spraying and killing.
Fungus Gnats
Crassulaceae succulents have a relatively high probability of developing fungus gnats. The larvae eat the tender buds of the succulent, causing the plant to become infected.
Prevention and treatment methods: Fungus gnats like humus, so the planting soil should preferably avoid this type of material. In addition, paying attention to maintaining the degree of dryness and moisture of the pot soil is very important. If flying insects are found, choose a suitable insecticide for spraying and killing.
To avoid succulents getting sick, the most important thing is to do a good job of ventilation and care. An excessively shady and damp environment will not only cause bacteria to breed, but may also trigger pest problems. Therefore, doing a good job of daily ventilation and preventing the environment from being stuffy, hot, and humid is crucial for growing succulents.
