Is Sooty Mold Dangerous
Generally, it is harmless to humans. Sooty mold is unpleasant to look at but luckily it is a harmless fungus disease that grows on the branches, leaves, and also the fruit of most fruit trees.A fruit affected by sooty mold doesnt look very appetizing, however, its edible. Simply remove the mold with warm soapy water. The fungi are non-parasitic and non-pathogenic to plants. However, although harmless in general, a massive presence of this mold on the leaves could interfere with the trees growth and its ability to benefit from solar energy .
Often this fungus occurs when trees are in the shade or they have an excess of foliage. If not treated, the lack of sun will prevent the tree from bearing fruit.
How To Kill Sucking Insects & Prevent The Mold
If you kill the sucking insects and prevent their return, the mold goes away. Ill give you two ways to do this.
1. Apply Bayer Advanced Tree & Shrub Protect & Feed according to label directions. This product contains a systemic insecticide thats absorbed by the plant. When insects suck the sap, they suck in the systemic and it kills them. This product works for months.
2. If you prefer a natural pesticide, spray all leaf and stem surfaces according to label directions with an all-season horticultural oil. This product kills insects, their larvae, and their eggs on contact, but it doesnt keep them from returning. So youll have to spray multiple times.

Does Sooty Mold Spread
Sooty mold is a fungal disease that can spread to any area of an infected plant that is coated with honeydew. Honeydew is the sweet, sticky substance that is secreted onto plants from small, sucking insects such as aphids, whiteflies, scale, and mealybugs. Large infestations of these pests can lead to plants covered in honeydew. Sooty mold fungal spores adhere to the leaves of infected plants by sticking to the honeydew on the surface of the foliage. Sooty mold fungus then quickly spreads to all of the areas of the plant where honeydew is present.
To kill and remove sooty mold fungus from affected plants, destroying the pests responsible for the infection is first and foremost. After the pest infestation is contained and destroyed, sooty mold can then be removed from the affected plants. If sooty mold removal was successful, the plant should remain free of any signs of the fungus. Sooty mold cannot spread without the presence of honeydew, so if the mold starts to come back, that means that the pests that caused the fungus are still present.
Control Insects That Produce Honeydew
Good gardening practices can help to prevent the pest infestation that can lead to an outbreak of sooty mold.
Healthy plants are less susceptible to insect infestations. Be sure to maintain airflow by correct spacing between plants, provide adequate irrigation, and keep the garden free from weeds and plant debris that may play host to pests.
You may not need to resort to the use of insecticides to control the infestation.
In the case of aphids, whiteflies, and softscale, something as simple as using a strong blast from a hose to dislodge the pests from a tree branch can do the trick.
You can also use an insecticidal soap, neem oil, or horticultural oils.
If the insects are limited to a small part of a shrub or tree, you might be able to get rid of them by carefully pruning out the infested area.
Keep in mind that SLF infestations are so difficult to control that this approach is generally not feasible.

It is important to identify the responsible pests for the infestation and kill them as soon as you notice them.

To treat your plant against these pest, spray the leaves with a solution of either horticultural oil or neem oil. Horticultural oil and neem oil are less toxic pesticides that will rid your plant of heavy infestations. Spray in the early evening after the plant is no longer in direct sunlight. Just like tanning oil, neem and horticultural oil can exaggerate the effects of the sun and you run the risk of sunburning the leaves if you apply in full sun. Depending on the severity of the infestation, repeat applications may need to be made every two weeks or so. Always follow the directions when using any pesticide.
Step 2: Soot Removal
You remove the soot in the same way you would remove greasy caked on goo in the kitchen, by letting it soak in dishwashing liquid. Use your sprayer and hose down the plant with a solution of dishwashing soap. This step does double-duty by cleaning up the sooty mold and killing some of the pests that cause sooty mold. Avoid using a degreaser or soap/detergent for an automatic washer. Let the soap stay on the plant for a while as it loosens up the soot.

What Was The Black Soot On My Gardenias
The sooty substance is actually called sooty mold, and it is a fungus that is spread by insects. It is an unattractive nuisance, but in itself it is rarely lethal.
According to the Cooperative Extension Service of Hawaii, the most common sooty molds are Cladosporium, Aureobasidium, Antennariella, Limacinula, Scorias, andCapnodium.
Sooty mold is easily differentiated from other diseases by the ease with which it wipes off. It does not actually penetrate the leaf’s surface, so no damage is done to the structure of the plant. The fungus will interfere with the plant’s photosynthesis process, so a severe infestation will weaken a plant considerably.
Symptoms Of Sooty Plant Mold Growth
Sooty mold looks a lot like the name implies. Your plants twigs, branches, or leaves will be covered in a grimy, black soot. Many people believe that someone may have dumped ashes or may have even caught the plant on fire when they first see this plant mold.
Most plants affected by this plant mold growth will also have some sort of pest problem. Some plants, like gardenias and roses, which are prone to pest problems, will be more susceptible to this plant mold growth.

Getting Rid Of Insects
Look for insects including aphids, whiteflies, leafhoppers, mealybugs and scale.
Check both sides of the leaves, the trunk and any flowers or fruit on the bushes.
Spray infected parts of the plant with pre-mixed insecticidal soap spray, coating the insects directly until the leaf area is dripping slightly.
Check for re-infestation weekly and follow up with additional treatments once a week until the insects disappear.
Things You Will Need
Pre-mixed insecticidal soap
Sooty mold comes off naturally as rain, wind and sun break down the fungus, so if the soap and water cleaning doesn’t get rid of the problem, time often will, as long as you follow up with regular insect inspections and treat any problems as they appear.
Broadleaf evergreens clean up the best. Deciduous trees shed their leaves in the fall so any mold will disappear. You can clean deciduous trees but it’s often not worth the effort. As long as you keep aphids and other insects in check, the mold won’t return when the leaves re-grow. Needle-like evergreen shrubs are difficult to clean. Ideally, focus on getting rid of the insects rather than trying to clean individual needles.
Check and follow the warnings on pesticides to avoid personal harm or injury.
