Magnolia scale, a sap-sucking scale insect, is found on Magnolia species , as well as Japanese and Chinquapin Oaks, Kwanzan Cherry and other ornamentals. There are several species of Magnolia scale: the Asian, European, Coccus hesanius Linnaeus (syn. C. orientalis) and Platycotis vanderbilti Ashmead (aka palaestina ). The two most damaging are P. vanderbilti and C. hesanius .  Scale insects feed by inserting mouthparts into plant stems and tapping the plant vascular system for food. They suck out plant juices in excess of their own needs which weakens the plant, and if there are enough pests feeding on a host plant, it may cause death or at least stunt its growth. When the vine first appears to be dying back or becomes increasingly stunted and shriveled, systemic insecticide for magnolia scale is likely needed. Typically, this happens when nurseries or gardeners talk about how to get rid of white bugs on magnolia trees, they are talking about a type of scale called magnolia scales. Systemic insecticides are not labeled for the treatment of magnolia scale. The systemic insecticides containing imidacloprid or dinotefuran that are labeled for use on magnolia trees have a long list of restrictions and precautionary statements which make them impractical to use on any type of small-scale project like in home gardens.

Systemic Insecticide For Magnolia Scale

Section: Magnolia Scale

The Magnolia Scale is a sap-sucking insect that feeds on the plant’s nutrients. It can be controlled with a systemic insecticide, but first you must identify it. Magnolia scale insects are easy to detect because they look like brown or gray bumps on your magnolia leaves and stems. The nymphs are small and translucent white, while the adult female lays her eggs under her waxy coverings (scales).

Whiteflies

Whiteflies are a common pest of magnolia trees. These sap-sucking insects can cause yellowing and wilting of the leaves. Whiteflies are attracted to yellow sticky cards, so it is possible to monitor their populations in this way.

It is difficult to control whiteflies with insecticides because they are resistant to many chemicals commonly used against them. However, if you’re looking for an organic solution then try spraying your magnolia tree with neem oil on a monthly basis (or every two weeks during warm weather) until the problem subsides.

Plant Symptoms

The symptoms of magnolia scale infestation are quite distinctive and easy to recognize. The first signs of the pest are a yellowish discoloration on the leaves, often with a sickly appearance. As the infestation worsens, branches will droop or wilt as they become weak from nutrient loss. If magnolia scale is allowed to remain untreated long-term, it can lead to branch dieback and eventual plant death.

Black sooty mold (sooty mold) is another symptom that results from this pest’s feeding activities; honeydew excreted by adult scales creates an ideal environment for sooty mold growth if conditions are right (i.e., warm temperatures and high humidity). While not directly harmful to plants themselves, these black fungal mats serve as an indicator for other issues such as root damage caused by overfeeding–and therefore warrant immediate attention!

Home Remedies

A systemic insecticide is the best way to control magnolia scale. However, be careful when using these products on tender plants. Another option is to use insecticidal soap, which can be applied in the early spring before new growth emerges from buds or twigs. Follow label instructions carefully and avoid getting any product on leaves or flowers.

Pesticide products are available at garden centers and hardware stores.

Solutions

A systemic insecticide is an insecticide that is taken up by a plant through its roots and transported to other parts of the plant. This type of insecticide can be used to control scale insects because it is applied to the soil around your magnolia and will kill all insects feeding on them, even those inside your tree.

You should use a systemic insecticide when scale are actively feeding in early spring (before the buds open), as this will give it time to move throughout the tree before any eggs hatch later in the summer. However, be aware that some systemic insecticides may harm other plants nearby if they are sprayed too close or during flowering times when bees are present on your property (such as roses). Therefore, you should always follow directions on labels when using any kind of pesticide so as not to risk damaging sensitive plants around yours!

Magnolia Scale can be controlled with a systemic insecticide, but be careful about using these kinds of products on tender plants.

Magnolia scale is a common pest that can be controlled with a systemic insecticide. However, you should use these products carefully as they are not always safe for your plants. Systemic insecticides work by getting into the plant and affecting its vascular system, which then kills the insect pests that suck on it.

Systemic pesticides can be harmful to plants if they’re applied incorrectly or at the wrong time of year, so make sure to read the label carefully before applying them and try to avoid doing so during rainy days or when there’s already standing water around your trees.
