Although frangipanis are fairly kado pernikahan unik, kado untuk pernikahan, there are some pests and diseases that may affect them, predominantly fungus, level, frangipani rust and stem rot.
Fungus, Mold & Powdery Mildew
Leaves affected by fungus or mold could be sprayed with a copper based fungicide and white oil solution. If you like organic solutions, try a mixture of powdered milk powder and white oil or detergent.
Keeping plants well nourished aids in preventing fungal infections. Potash is particularly good for improving disease resistance in frangipanis.
Leaves affected by hemispherical level have dark to light dark brown bumps that are glossy, clean and hemispherical. Leaves may possess a black sooty coating.
Scale can be treated by with white oil in spring to early summertime. If you like organic solutions, try encouraging natural predators to your garden, such as for example ladybugs, the scale consuming caterpillar, and parasitic wasps. Many vegetation attract ladybugs including daisies, zinnias, and zucchini.
There is a fresh disease attacking in Australia known as frangipani rust. It is most noticeable in late summer season and early autumn. An orange to yellow powdery substance (in fact pustules) appears on the underside of leaves. They rupture and pass on spores which pass the condition to other plants close by. The higher sides of the leaves are dark brown and discoloured. Severe infections may cause the leaves to drop prematurely and may result in the death of small plant life, however larger trees may actually suffer no ill effects (aside from leaf drop).
To control frangipani rust try using a fungicide (such as for example Mancozeb) in the warmer months to slow the advancement of the disease. Losing all fallen leaves in winter and spraying the tree and the area under the tree with a fungicide may slow the reappearance of frangipani rust following season.
The good thing is that lately some frangipani trees have developed a resistance to rust, so that it may be on it's way out.
Stem Rot & Black Tip Dieback
As frangipanis reduce their leaves over winter season, soft, withered stems could become visible. It's a condition called stem rot' and it's quite common in trees which have been stressed by frosts, drought, insufficient sunlight or just the usual age.
The easiest method to keep it in order is to basically prune off any diseased growth, but when you do, it's important to be sure you cut it right back to good, healthy tissue.
Dying tip growth is often referred to as black suggestion dieback. Some newer deciduous cultivars and evergreen frangipanis are especially prone to the disease.
Industrial frangipani growers suggest the issue can be worse in areas where fruit-spotting bug and beetle activity can be high. It is because any insect attack on the tip of the plant predisposes it to a second dieback infection.
Affected plants typically reshoot beneath the damaged portion of stem. If plant life appear unsightly or you are concerned that the rot is normally advancing down the stem, use sharp pruners to lessen to clean tissue. Make sure to use warm water or household disinfectant to completely clean pruners between cuts in order to minimise potential disease transfer.
