Frangipani (plumeria) Pests And Diseases

Although frangipanis are pretty hardy, there are several pests and diseases that may affect them, kado unik, hadiah ulang tahun fungus, scale, frangipani rust and stem rot.

Leaves suffering from fungus or mold can be sprayed with a copper based fungicide and white oil solution. If you like organic solutions, try a combination of milk powder and white oil or detergent.

Keeping plants well nourished helps prevent fungal infections. Potash is particularly good for improving disease level of resistance in frangipanis.

Hemispherical Scale
Leaves affected by hemispherical level have dark to light dark brown bumps that are glossy, simple and hemispherical. Leaves may have got a black sooty coating.

Scale can be by spraying with white-colored oil in springtime to early summer. If you prefer organic solutions, try encouraging organic predators to your garden, such as for example ladybugs, the scale consuming caterpillar, and parasitic wasps. Many plant life attract ladybugs which includes daisies, zinnias, and zucchini.

Frangipani Rust
There exists a new disease attacking frangipanis in Australia called frangipani rust. It really is most noticeable in late summer and early autumn. An orange to yellow powdery substance (in fact pustules) appears on the lower of leaves. They rupture and spread spores which pass the condition to other plants close by. The top sides of the leaves are dark brown and discoloured. Severe infections may cause the leaves to drop prematurely and will result in the death of small vegetation, however larger trees may actually suffer no ill effects (apart from leaf drop).

To control frangipani rust try using a fungicide (such as for example Mancozeb) in the warmer weeks to slow the advancement of the disease. Disposing of all fallen leaves in wintertime and spraying the tree and the region beneath the tree with a fungicide may slower the reappearance of frangipani rust following season.

The good thing is that lately some frangipani trees have built up a resistance to rust, so it may be on it's way out.

Stem Rot & Black Tip Dieback
As frangipanis shed their leaves over winter, soft, withered stems may become visible. It's a disorder called stem rot' and it's really quite common in trees that have been stressed by frosts, drought, lack of sunlight or just plain old age.

The ultimate way to keep it in order is to simply prune off any diseased growth, but when you do, it's important to make sure you cut it back to good, healthy tissue.
Dying tip growth is often referred to as black tip dieback. Some newer deciduous cultivars and evergreen frangipanis are particularly prone to the disease.

Commercial frangipani growers suggest the problem is certainly worse in areas where fruit-spotting bug and beetle activity is high. The reason being any insect attack on the end of the plant predisposes it to a second dieback infection.
Affected plants typically reshoot beneath the damaged part of stem. If vegetation appear unsightly or you are worried that the rot is certainly advancing down the stem, use sharp pruners to lessen to clean tissue. Be sure to use warm water or household disinfectant to completely clean pruners between cuts so as to minimise potential disease transfer.
