Undoubtedly, on some occasions, your plants have suffered the attack of the imaging. A fungus that is characterized by creating a kind of black dust on the surface of the leaves. Something that is quickly detected, since it significantly affects the appearance of a particular plant. While it is true that his presence does not have significant consequences on her, that is why we cannot let him be at ease. The imaging or black fungus is nothing more than a symptom of something more important: the existence of a pest.
Although its appearance is widespread during the summer months, it is not exclusive to this season. In those areas with warm autumns, it is more than likely that the fumagina appears in our plants. And, although its effects are not harmful in domestic plants, the same is not right with fruit trees and garden plants. In these two cases, the presence of fumagina is synonymous most of the time of ruined harvest.
For these reasons, it is important to know how to detect fumagina. And, most importantly, know how to eliminate it in time.
WHAT IS FUMAGINA AND WHY IT APPEARS
To begin, it is important to understand that fumagina is an opportunistic fungus. Or, what is the same, only uses the plant as support and appears in our plants as a result of other insect infections. The black fungus is seen in areas of the leaves where, previously, there is a molasses residue excreted by certain pests.
Thus, these black spots are nothing more than the synonym that our plant has aphids, mealybugs, or whiteflies. Three of the most common garden pests and which, unlike the fumagina, can compromise the health of a plant.
In an initial stratum, the imaging manifests itself as a slight dark powder on the leaves. At this time of infection, it can be removed without much complication simply by swiping your finger. However, over time, the fungus can colonize and harden on the leaves.
In addition to shaving the whole, this entails something that can be negative for the plant. And, when the fungus proliferates, it ends up completely covering the leaves. A fact that prevents photosynthesis from being carried out normally. Or, what is the same, that despite the irrigation that we apply, the plant can not feed on one of the foods of any plant: sunlight.
HOW TO ELIMINATE THE FUMAGINA
Before going into detail on how to eliminate smoking, we have to consider something more immediate. We mean eliminating pests that are affecting our planet. Some that, unlike the black fungus, can end it.
As always, when we talk about eliminating pests, the first step is to identify it. The best way to choose the right insecticides for each of them. Or, if we prefer, we can opt for a broad-spectrum insecticide that stops infections of different insects.
We can also opt for an insecticide with a broader spectrum. We refer to one that not only serves to stop insect pests but also fungi and mites. In this way, we will be fighting all those enemies of our plants simultaneously.
Once we have taken the appropriate measures with insects, it is time to deal with the imaging. Ideally, clean the plant thoroughly, sheet by sheet. We can do it with a cloth or using a sheet cleaner. Thus we will eradicate its presence, and we will be preventing it from hardening.
It is not too much to carry out a good sanitation pruning. It is very likely that in the areas most affected by imagining, there is a greater presence of the plague that has attracted it. If we eliminate them, we will be helping the plant to regrow more strongly and free of uncomfortable inhabitants.
STRENGTHEN AND TREAT THE PLANT TO AVOID IMAGINE
Another of the usual doubts about fumagina is how to prevent it from appearing in our plants. Something that has a lot to do with the general state of a plant. A well-nourished plant will be much more resistant to attack by any opportunistic pest or fungus. However, a plant decayed either due to lack of nutrients in the substrate, due to lack of fertilizer or irrigation is more exposed.
To avoid this, the ideal is to fertilize the plants according to your needs. And, at the beginning of spring and autumn, add a rich organic substrate that can nourish them deeply.
But in addition to this, it does not hurt to treat the plant before it appears. Thanks to this prophylaxis, we will be guaranteeing that the imaging cannot be installed in our plants. Ideally, from the beginning of autumn until spring, we apply a copper-based fungicide. A gesture that will help us prevent the black fungus from installing and proliferating.
Despite its effectiveness, it is important to consider a couple of aspects. On the one hand, that does not exceed the indications of each manufacturer. By having copper in its compound, an excess can ruin our plant. And, on the other hand, it is important that we always apply it when there are no high temperatures. That is why it is ideal to wait for colder seasons to use it.
