The following is the pest and disease prevention and treatment for the bird of paradise, with a total of 4 pests and 4 diseases. Let's read on.

II. Pest and Disease Prevention and Treatment for the Bird of Paradise

(1) The 4 Pests of the Bird of Paradise

1. Coconut concave scale (Pinnaspis buxi)

Damaged parts: The leaves of the bird of paradise, gathering on the underside of leaves to suck sap.

Symptoms of infestation: Yellow-green spots appear on the upper surface of the bird of paradise leaves, and in severe cases the growth and development of the entire plant is affected.

Prevention and treatment: After discovering branches and leaves infested by the pest, promptly prune and burn them to reduce the source of infection. In addition, evenly spray a 1000-fold dilution of 90% trichlorfon for control.

2. Snails

Damaged parts: The flowers and tender leaves of the bird of paradise.

Time of appearance: As one of the main pests of the bird of paradise, snails generally appear in the evening or after heavy rain. They gnaw on the flowers and tender leaves of the bird of paradise, causing serious damage to its appearance.

Prevention and treatment: Promptly remove dead branches and fallen leaves. Once pests are found, manually capture and kill them, or spray 50% phoxim and 80% dichlorvos for chemical control.

3. Scarab beetles

Damaged parts: The young tender parts of the bird of paradise roots, causing broken and damaged roots.

Symptoms of infestation: Leaves turn yellow, the plant becomes thin, and in severe cases seedlings wither and die.

Prevention and treatment: After discovering scarab beetles, shake the plant in the early morning or evening to make the beetles fall off, then gather and kill them. In addition, you can also spray a 1000-1500-fold dilution of 50% malathion for control.

4. Stem borers

Damaged parts: The tender shoots and flower buds of the bird of paradise.

Symptoms of infestation: As one of the main pests of the bird of paradise, stem borers often use their larvae to bore into the tender stems of the bird of paradise, causing dead heart seedlings.

Prevention and treatment: When stem borer larvae are found, use 50 ml of 4.5% beta-cypermethrin emulsifiable concentrate mixed with 60 kg of water for spraying, once a week, spraying 2-3 times consecutively. If they are adult stem borers, the plant is at risk, so be sure to observe carefully.

(2) The 4 Diseases of the Bird of Paradise

5. Brown spot disease

Cause: This disease is one of the notable diseases of the bird of paradise. It generally spreads through watering, human handling and other means, and mostly infects and damages leaves that are weak in growth or have wounds.

Symptoms: Brown lesions appear on the leaves, surrounded by yellow halos; afterward they slowly expand, and the lesions become irregular in shape with red-brown edges; in the later stage, the lesions turn black and black granular bodies appear.

Prevention and treatment: When the above symptoms are found, immediately spray a mixture of a 1000-fold dilution of quintozene fungicide and a 1500-fold dilution of nicotine insecticide, spraying several times consecutively.

6. Anthracnose

Cause: This disease mainly occurs in spring, spreading through wind, rain and insects, entering through wounds.

Symptoms: Round or nearly round lesions appear on the bird of paradise leaves, with red-brown thin lines at the edges and gray-brown centers. Old leaves generally develop the disease in early April in the first half of the year, and new leaves develop it in August in the second half of the year.

Prevention and treatment: Promptly prune diseased leaves when found, or remove them and burn or bury them deeply to reduce the source of infection. Apply or spray a 1000-fold dilution of 70% copper oxychloride suspension or an 800-fold dilution of 25% Shibaike emulsifiable concentrate on the wounds, preferably alternating sprays to prevent pesticide resistance.

7. Leaf spot and blight

Cause: One of the diseases of the bird of paradise, it mainly appears in spring, with conidia escaping from pycnidia for primary and secondary infection, causing the disease to spread continuously. Weak plant growth and alkaline potting soil make the plant prone to the disease.

Symptoms: The bird of paradise leaves first develop gray-white blighted spots, with brown-purple rings at the edges and many small black granular dots on them.

Prevention and treatment: Prune off diseased leaves, then apply 30% basic copper sulfate suspension to the wounds. When the above symptoms are found, spray a 400-fold dilution of 30% basic copper sulfate suspension or an 800-fold dilution of 47% Kasumin wettable powder, once every 10 days or so, for 2 to 3 consecutive treatments.

8. Gray mold disease

Cause: This disease spreads through wind, rain and insects, infecting through wounds. When planting is too dense, humidity is high, light is insufficient, or nitrogen fertilizer is applied excessively, the bird of paradise is prone to gray mold disease.

Symptoms: Dark green to dark yellow-white small spots appear on the leaves, appearing water-soaked. Under high temperature and high humidity conditions, the lesions expand rapidly into brown irregular shapes, causing large areas to rot, and a gray mold layer grows.

Prevention and treatment: When the above symptoms are found, use a 500-fold dilution of 80% captafol wettable powder, or a 500-fold dilution of 75% chlorothalonil for spray control.

That is all about the pest and disease prevention and treatment for the bird of paradise. I believe everyone now knows what to do when a bird of paradise gets pests or diseases! Overall, the bird of paradise is very prone to illness, so to avoid unnecessary trouble, everyone should still take careful care of it! Otherwise, these troublesome issues will come one after another, extremely annoying! Finally, may everyone's bird of paradise bloom with beautiful flowers.

The Blooming Period of the Bird of Paradise; Pest and Disease Prevention and Treatment of the Bird of Paradise

The bird of paradise, also called the paradise bird flower, is native to South Africa. After blooming, its appearance resembles a crane raising its head and gazing into the distance, hence the name bird of paradise. Let's take a look together at the knowledge about the blooming period of the bird of paradise and its pest and disease prevention and treatment.

The blooming period of the bird of paradise:

Generally speaking, the cultivation period of the bird of paradise is very long. It is usually sown in March, and only after 2 years can the bird of paradise be planted out. After planting out, it is propagated by division. Once mature, it blooms every winter, and the blooming period is very long, lasting until June of the following year. If artificial pollination is carried out during the blooming period, when the flowers wither and set seed, we can also collect and dry them for a new round of sowing.

Pest and disease prevention and treatment of the bird of paradise:

1. Bird of paradise gray leaf spot

Bird of paradise gray leaf spot mainly occurs on the leaves. The lesions are initially dark brown spots, and multiple lesions join together, or a single lesion expands into an irregular shape, gray-brown inside with dark brown edges; in the later stage the lesions dry up, and under humid conditions black granular bodies appear on the lesions.

Solution: Promptly clean up diseased and residual tissue, avoid causing wounds to the plant during care, strengthen ventilation and light transmission, increase leaf surface spraying, and keep the leaf surface clean and moist. In the early stage of the disease, spray an 800-fold dilution of Tuzet broad-spectrum fungicide.

2. Bird of paradise anthracnose

Bird of paradise anthracnose is caused by Colletotrichum, a type of deuteromycete fungus. The pathogen overwinters as mycelium on diseased leaves and diseased residues, and the following spring spreads through wind, rain and insects, entering through wounds. Old leaves generally develop the disease in early April, and new leaves begin to develop it in August. The disease is prone to occur when humidity is high, and worsens with water accumulation in the pot and poor ventilation. The disease mainly damages leaves. The lesions are round or nearly round, with red-brown thin lines at the edges and flat gray-brown centers, about 6×4 cm in size. When the acervuli mature, small black granular dots are exposed. Generally, old leaves develop the disease in the first half of the year and new leaves in the second half.

Solution: When diseased leaves are found, prune them from the edges, or remove the diseased leaves and burn or bury them deeply. Spray a 500-fold dilution of 25% carbendazim wettable powder, or a 500-fold dilution of 40% sulfur-multi suspension, a 1000-fold dilution of 70% copper oxychloride suspension, an 800-fold dilution of 25% Shibaike emulsifiable concentrate, a 500-fold dilution of 50% captan, or a 1000-fold dilution of 75% thiophanate-methyl.

3. Bird of paradise gray mold disease

Solution: Spray the plant with water as little as possible, apply more potassium fertilizer, and ensure good ventilation; in the early stage of the disease, spray a 500-fold dilution of 75% chlorothalonil wettable powder once every 10 days, for a total of 2-3 applications.

4. Bird of paradise damping-off disease

For the prevention and treatment of bird of paradise damping-off disease, attention should be paid to soil disinfection. When planting, the plant spacing should not be too small, planting should not be too deep, old leaves should be pruned promptly, ventilation and nutrient management should be strengthened, and the plant's growth vigor should be increased.

Solution: Immediately pull out diseased plants when found, and carry out local soil disinfection. During the growing period, regularly spray validamycin to achieve early prevention and treatment.

5. Scale insects

When indoor cultivation has poor ventilation, scale insect damage is likely to occur. They generally parasitize the stems, leaves and inflorescences of the bird of paradise. Their adults and nymphs use piercing-sucking mouthparts to suck plant sap, causing leaves to curl, turn yellow and age, affecting plant growth, and in severe cases causing dead leaves, leaf drop, and even the death of the entire plant; at the same time, when scale insects infest, they excrete large amounts of honeydew at the wounds, polluting the leaves and causing sooty mold, producing a layer of black mold on the leaves, affecting the normal growth and blooming of the bird of paradise.

Solution: Carry it out shortly after the nymphs hatch, before they have formed a waxy shell. Pesticides that can be used include a 1000-fold dilution of 40% dimethoate, or a 250-fold dilution of 50% trichlorfon, or a 1000-1500-fold dilution of 80% dichlorvos emulsifiable concentrate, or a 2000-2500-fold dilution of 2.5% deltamethrin emulsifiable concentrate. Generally, spraying 1-3 times consecutively with an interval of 7-10 days each time gives better results. In addition, special attention should be paid to the fact that scale insects easily develop resistance to pesticides, so the use concentration and alternating use of pesticides should be well managed.

6. Scarab beetles

The larvae of scarab beetles are called white grubs. They feed underground on the young tender parts of the bird of paradise roots, mostly causing broken and damaged roots. When the damage is light, seedling growth is hindered, leaves turn yellow or the plant becomes thin; when the damage is severe, seedlings wilt, yellow and die.

Solution: During the adult occurrence period, mix sugar, vinegar, white liquor and water in a ratio of 1:3:2:20 to make a liquid, add a small amount of pesticide liquid, put it into a canning jar, and hang it in the planting area for trapping and killing. When pest damage occurs, directly spray a 1000-1500-fold dilution of 50% malathion for control.

7. Stem borers

The bird of paradise stem borer, also called the bird of paradise shoot borer, specifically damages tender shoots and flower buds, leaving frass at the bore holes, causing great harm. The main way it causes damage is by larvae boring into the tender stems of the bird of paradise, destroying the growing point and causing dead heart seedlings.

Solution: During the larval stage, use 50 ml of 4.5% beta-cypermethrin emulsifiable concentrate, or 50 ml of 20% fenvalerate emulsifiable concentrate, mixed with 60 kg of water for spraying, once a week, spraying 2-3 times consecutively.

8. Snails

Snails mostly hide in dark, moist places during the day and come out at night to move about, especially in the early morning or evening after heavy rain, when they come out in groups to gnaw on the tender leaves and flowers of the bird of paradise, affecting its ornamental value.

Solution: Use a 1000-1500-fold dilution of 50% phoxim, 80% dichlorvos, etc. for control, spraying once every 5-7 days, for 3-5 consecutive times.
