Common pests and diseases of fuchsia and their control methods
Common diseases of fuchsia and their control
Gray mold
Gray mold mainly occurs on stems, leaves and flowers. Leaves infected with gray mold develop brown spots along their edges, and when exposed to water or in humid conditions, the diseased leaves produce gray mold-like growth. Stems and flower buds infected with gray mold develop purplish-brown spots, leading to rot of the flowers and stems.
The control methods are: First, strengthen cultivation management, cultivate reasonably, and pay attention to ventilation. Second, when potting, make sure the potting soil is sterile or disinfected soil. Third, thoroughly remove infected plants and burn them in a centralized manner. Fourth, treat the soil with a mixture of quintozene wettable powder and zineb wettable powder, or use a specific Bordeaux solution, thiophanate wettable powder, etc. for control.
Physiological root rot
This disease occurs easily in summer. The main cause is excessive watering and overly moist soil, resulting in oxygen deficiency, which causes the plant's roots to turn black and rot, and in severe cases can lead to the death of the whole plant.
The control methods are: First, loosen the soil in time to keep the soil well ventilated, and water appropriately. Second, in summer, when physiological root rot is likely to occur, move it to a shaded and ventilated environment for care.
Common insect pests of fuchsia and their control
Aphids, red spider mites
Aphids and red spider mites suck the sap from the flowers and leaves of fuchsia, causing the leaves to shrivel and drop, and in severe cases can lead to the death of the whole plant. The control method is to use a specific dimethoate solution, fenpropathrin and deltamethrin solution for spraying control.
Whiteflies
Whiteflies suck the sap from the leaf mesophyll, mainly harming the young leaves of fuchsia, causing the leaves to curl and dry up. When whitefly infestation is found, promptly spray a specific omethoate or fenvalerate solution, about once every seven days, spraying three or four times.
Fuchsia is very susceptible to pests and diseases, so gardening friends should take good care of them.
