II. Pest and disease prevention and control for bougainvillea (pests)
1. Aphids
Aphids are a pest that can appear on many plants, and bougainvillea is no exception. They mainly use nymphs to suck the sap from leaves, stems, tender tips and tender ears, causing the plant to lose a large amount of nutrients and finally wither.
Prevention and control method: For aphids, this pest and disease problem of bougainvillea, the most direct method is to use a pesticide to spray and kill them. In terms of pesticide, we can choose a 3000-fold dilution of 50% pirimicarb wettable powder.
2. Scale insects
Scale insects are an extremely harmful pest, mainly threatening the leaves, branches and fruits of the flamingo flower. They gather on branches, leaves and fruits, causing leaves to turn yellow, branch tips to wither, tree vigor to decline, and they can also trigger sooty mold.
Prevention and control method: When dealing with scale insects, this pest and disease problem of bougainvillea, we can directly use a 1000-fold dilution of 45% malathion emulsifiable concentrate to spray and kill them.
III. Pest and disease prevention and control for bougainvillea (diseases)
1. Leaf spot disease
Leaf spot disease, as its name suggests, harms plant leaves. When it occurs, many irregular lesions appear on the leaves of bougainvillea, and as time goes on small black dots also appear on the lesions, greatly affecting the ornamental value.
Prevention and control method: When dealing with this pest and disease problem of bougainvillea, we can use a 500-fold dilution of 50% carbendazim wettable powder to spray the diseased plant. Generally spray once every 7-10 days, and after 3-4 times it is enough for it to recover.
2. Brown spot disease
Brown spot disease, also called Rhizoctonia damping-off blight, is a fungal disease caused by Rhizoctonia solani. When it occurs, many yellow-brown to light brown lesions with a diameter of 0.1-0.5cm appear on the leaves, and as time goes on the lesions gradually spread, eventually causing the plant to wither and die.
