Control methods of high incidence of diseases and insect pests of succulent plants in summer

Disease prevention and cure

Stem rot

Stem rot mainly harms the succulent stem base, which will produce dark brown when the disease occurs, which slowly makes the stem and branches of the plant rot and soften, and when it is serious, it can cause the whole plant to die.

Control methods: stem rot is mostly caused by fungi, so more attention should be paid to ventilation in daily maintenance, and reasonable water and fertilizer management should be carried out. The base soil of culture is best used after disinfection. When a disease occurs, carbendazim or benzoylammonium can be sprayed for prevention and treatment.

Anthrax

Anthracnose mainly harms succulent succulent leaves. When the disease will produce brown leaf spots and, disease spots will gradually expand with the aggravation of the disease, gradually showing brown, serious will lead to fallen leaves.

Prevention and treatment methods: when diseased spots are found, diseased branches and leaves should be removed in time, and attention should be paid to cleaning basin soil during daily maintenance, and sterilization should be done in time. After the disease is found, carbendazim or Bordeaux liquid and other drugs can be sprayed for timely prevention and treatment.

Soft rot

The phenomenon of fleshy stems and leaves will appear in the early stage of soft rot, and when the disease is serious, the surface of the plant will appear sticky wet rot and give off an unpleasant smell.

Prevention and cure method: pay more attention to ventilating the meat and control watering at the same time to avoid the basin soil being too wet. Early prevention and treatment of the disease, spraying streptomycin or Bordeaux solution for treatment and control.

Epidemic disease

The blight mainly harms the roots of succulent plants. There will be dark brown water stains and sometimes a white mildew layer in the victimized site.

Prevention and treatment: in the process of succulent maintenance, pay attention to keep the basin soil clean, and the cultivated soil should be used after sterilization. Spraying copper and other drugs can effectively prevent and cure it.

Black spot disease

Black spot disease often harms succulent succulent leaves, which will produce black spots on the leaves and rot in severe cases.

Prevention and treatment: after the discovery, timely drug treatment, can be sprayed carbendazim or chlorothalonil for prevention and treatment, after a period of time, the disease can be well controlled.

Soot disease

The occurrence of soot disease must be dealt with in time, because soot disease has a strong infectivity. Most of the causes are due to the hot and humid growing environment of succulent plants.

Prevention and control methods: daily maintenance pay attention to ventilation, pay attention to the proportion of watering, can be appropriate amount of wine dilution spray, the latter choose carbendazim for spraying.

Pest control

Shell worm

Scale insects mainly harm succulent stems and leaves. It feeds on the sap of the plant and often causes the meat to fall off and yellowing.

Control method: wash the plant with water, remove the insect pests, or find the insect pests, change the basin soil in time, and clean the leaves of the meat.

Whitefly

Whitefly larvae are parasitic in the plant and feed on sap. The secretion of whitefly can induce coal fouling disease and have a very bad effect on the health of meat.

Prevention and control methods: cover the ventilated environment and spray with insecticides such as marathons.

Small black flying bug

The probability of small black flying in the meat of crassulaceae is higher, and the larvae will eat the small buds of the meat, which will infect the plants.

Prevention and control methods: Xiao Hei Fei likes humus, so it is best to avoid such substances in the cultivated soil. In addition, it is very important to keep the dry and wet degree of the basin soil. When flying insects are found, suitable pesticides can be selected for spraying.
