I want to save my plant. Thanks
Answer: ficus benjamin parasites
the presence of very fine cobwebs is a fairly clear symptom of the presence of red spider mites: they are tiny arachnids, mites, which lurk on the underside of the leaves, ruining them conspicuously; usually the leaves turn yellow, but if you look closely, you can see large amounts of small yellow marks, all of which appear close together to form a single yellow spot; they are the bites of mites, which suck the sap from the foliage. These small animals are definitely harmful and must be quickly eradicated, to prevent them from becoming many and ruining the whole plant. Mites are not insects, and therefore most common insecticides have no effect on them; It is necessary to treat the plant with an acaricide, or with a broad-spectrum insecticide, which also has an effect on mites. I also remind you that these insects tend to develop in areas with little air exchange and characterized by a very dry climate; therefore they tend to develop especially in the apartment, or even in the height of summer on the plants of the terrace. Now that the season is quite cool and humid, if you could move the ficus outdoors, in the garden or on the terrace, the problem with the mites would tend to be considerably limited, as with nighttime minimum temperatures below 20 ° C and a crisp and moist air, mites do not develop so quickly. In addition to guaranteeing a better climate for the plant, moving the ficus outdoors will make it easier to sprinkle it with insecticide, without filling the house with a product that is certainly not healthy even for humans; or you can choose a systemic acaricide, that is to say that it will be added to the water of the waterings, and therefore it will be absorbed by the roots, entering into circulation in the leaves: in this way you can be sure of having supplied acaricide to every single insect. If the plant has many mites it is advisable this second type of acaricides, as often the products that are vaporized on the foliage work by contact on the animals, and do not have a subsequent repellent action; so if you can't hit all the mites, or if there are eggs, you will hardly be able to eradicate the parasite, and in a few weeks you will find yourself with the plant still suffering due to a second attack. To help your ficus recover quickly from pest attack, don't forget to start again with periodic fertilizer supplies, to be done every 12-15 days.
