Named plant diseases that are similar to each other in the video
one Gray rot and mosaic
Gray rot is a fungal disease, and mosaic is viral. In both cases, dark spots appear on the leaves, which can be misleading. But with gray rot, you can also see fluff — this is mold. With a mosaic virus, the spots are smooth, it seems that the leaves just started to dry out from the inside.
What to do
Gray mold is almost impossible to cure, and the affected plant is best discarded before it infects the rest. Healthy flowers should be washed in the shower and treated with an antifungal spray for prevention. Most likely, they will also have to change their habitat, since gray mold occurs in damp, poorly ventilated areas.
From the mosaic virus of the green pet, you can have time to cure if you quickly notice the spots. Damaged leaves are cut off if possible, and the plant is quarantined and treated with antiviral drugs.
2 Powdery mildew and downy mildew
These are two fungal diseases in which light, fluffy spots appear on plants. In the first case, only the leaves are affected, and in the second, the disease passes to the stems and flowers. Another difference: powdery mildew spots are white, while downy mildew spots are yellowish with a gray tint.
What to do
Both diseases can be cured with antifungal drugs at an early stage, until the spots cover no more than 15-20% of the plant surface. But if the indoor flower has been ill with powdery mildew, in the coming months, nitrogenous fertilizers should be removed from its top dressing. It is also worth increasing the frequency of ventilation in the room. After downy mildew, it is necessary to carry out preventive treatment of leaves and stems with a one percent solution of Bordeaux liquid for a week.
6 most common houseplant diseases and how to treat them
3 Dry spotting and anthracnose
Two fungal diseases in which brown dry spots appear on the leaves. The disease spreads quickly enough throughout the flower, and it dies if treatment is not started in time. At the same time, dry spotting always goes from the lower leaves to the upper ones, without affecting the stem. Anthracnose also affects the stems and moves through the plant quite spontaneously.
What to do
If dry spotting is detected, the first step is to move the plant pot to a cooler room to slow down the development of the fungus. Then remove the most damaged leaves and start the fungicide treatment. In the case of anthracnose, all spots will have to be removed, because this fungus does not die even at sub-zero temperatures. After that, they are treated with fungicides, be sure to update the soil, as spores remain in it. All nearby plants also need to be treated for prevention.
four dropsy and leaf rust
Both diseases cause the formation of seals and protrusions on the leaves. But dropsy is more common in plants that accumulate moisture in them, such as succulents. This is the reaction of the plant organism to waterlogging of the soil, due to which some of the roots die. Irregularities on the leaves are either light green or dark brown. At the same time, rust is a fungus that provokes tubercles of yellow or orange colors.
What to do
In the case of dropsy, you do not need to worry, the affected areas will not die. Just reduce watering and loosen the soil in the pot more often. Rust will have to be treated with fungicides. Damaged leaves will fall off, but the plant can survive. After treatment, reduce watering a little and use only soil from the store for transplanting. Rust is often found in gardens, so you should not use the soil from there without pre-treatment.
