In a plant, spathiphyllum diseases are divided into several types:
These diseases can be caused by pests, fungal spores, viruses and bacteria. People call indoor flower Female happiness and White sail.
The roots of spathiphyllum love to feast on the root aphid, or root mealybug. If a cottony white or grayish coating appears on the walls of the pot or soil surface, this means that aphids have wound up in the roots. In the photo, the pest looks like this (Fig. 1). The pest can start in a pot from improper care and with contaminated soil. Before planting a flower, the soil is best treated with insects. Aphids settle on the roots, which are responsible for the absorption of moisture and nutrients from the soil, so the White Sail begins to wither and wither, and the leaves become not so green.
If spathiphyllum is watered in insufficient or excessive quantities, an excellent environment is created for the reproduction of root aphids. You can fight it if you water the flower 1-2 times a week with a weak solution of potassium permanganate.
If the flower began to lose the brightness of the leaves, and then completely fades without visible external damage, then the roots were affected by root rot. In this case, the plant must be transplanted by carefully removing the rotten roots. After removing the rotten parts of the roots, they are treated with Gliocladin. Frequent watering, too dense or excessively moist soil, and also soil with low acidity contribute to decay. Rot is caused by fungi. A flower needs to be watered less.
When the rot progresses, the leaves discolor, then turn yellow and fade (Fig. 2). Affected roots in spathiphyllum acquire a reddish-brown hue. When spores of fungi fall on the vegetative parts of Feminine happiness, the leaves become covered with brown spots. Infected leaves must be removed to avoid contamination of neighboring plants.
Another dangerous fungus for a plant is phytospore. It causes phytosporosis of the roots and leaf spotting. The roots soften and slowly die off, leaving the plant without nutrition. Do not allow stagnation of water in the pot. The next watering should be done only when the topsoil is dry.
The most common leaf diseases in spathiphyllum are chlorosis and hommosis (Fig. 3). Chlorosis plants are most often affected in the autumn-winter period, when it is quite cool on the windowsill. Some gardeners adhere to the same watering regimen in autumn and winter, forgetting to measure the ambient temperature. It was then that a disease called chlorosis creeps up. Also, this disease can occur against the background of existing root rot or damage to the roots as a result of a flower transplant. If the plant is overfed or it lacks nutrients, then this all affects the leaves - they begin to languish and turn yellow.
When foliage begins to fade under the influence of harmful bacteria, this condition is called plant hommosis. Spathiphyllum leaf plates gradually begin to blacken from the edges. The disease is dangerous for other flowers, and not just for Women's happiness. Affected leaf plates that are already not so green should be removed, the remaining healthy leaves should be washed with soap in running water at a temperature of 22-24 ° C.
In addition to bacteria and fungi, spathiphyllum can be attacked by pests.
Shchitovki settles not only on spathiphyllum, it can infect all plants in the house. Therefore, the pest needs to be urgently disposed of. Adult insects no longer become immobile, and young individuals are able to move. This is how one plant becomes infected from another (Fig. 4). How to save a plant from scale insects? This pest can be destroyed with a soap solution. If this does not help, then you can use a tobacco solution. Adult insects can be removed from the plant with a cotton pad dipped in kerosene or an alcohol solution. It is rather difficult to get rid of a scab. The infected plant can be rubbed with garlic juice or olive oil mixed with water with a brush. 4-5 tbsp. Are added to 1 liter of water. l olive oil and applied to the plant daily for 10 days. Continuous ventilation is still required. If the measures taken did not help, then they will have to fight with the help of chemicals.
Another dangerous pest of the vegetative part of the plant is the spider mite. It is easy to recognize it by a spider web coating on the leaves. You can remove it from the surface of the plant in the same way as the scab - soap and tobacco solution. Treatment should be started immediately so that other indoor plants do not become infected.
How to save spathiphyllum with fungal and insecticidal diseases? Another plant can be dusted with sulfur powder. Sulfur helps in the fight against pests such as spider mites and scale insects. Sulfur is also a powerful fungicide; it can destroy some types of fungi that infect the White Sail.
More often, young buds and flowers of Feminine happiness are affected by abiotic factors. If the room is too dry air or the plant is standing in bright sunlight, then the flowers curl, and young buds can completely fall off.
With excessive moisture, the spathiphyllum does not produce a peduncle long enough. And if the green inhabitant of the windowsill lacks nutrients, then the flowers become smaller in size.
Peduncles and flower buds of a flower are subject to attack by a spider mite and a scab. You can deal with these pests on these parts of the plant in a similar way as on the leaves.
For the prevention of insecticidal diseases, female happiness can be sprayed 3 times a month with an interval of 10 days with a garlic solution. For 1.5 liters of water, take the juice of 3-4 cloves of garlic.
If spathiphyllum grows poorly and does not bloom, and there are no visible visible damages, then the plant needs a smaller pot. All this is due to the fact that the White Sail develops a powerful root system, and then it begins to build up green biomass and bloom. If you want the plant to bloom faster, just transplant it into a smaller pot.
And if the plant builds up green biomass very well, but does not bloom, then this is a sign of a lack of potash and phosphorus fertilizers. The plant has few nutrients.
Due to too dry air, the leaves of the plant may dry at the tips, it must be sprayed daily. If the flower suffers from root rot disease, he needs to spray the green shoots, but it is better to cover the soil with a film during spraying so that it does not absorb excess moisture.
The ambient temperature should be in the region of 22-24 ° C. And in winter, it should not fall below 15 ° C. But then watering should be reduced.
Every year Feminine happiness requires a new pot for itself. In diameter, it should be 2-3 cm larger than the previous one. Then the plant will grow well and bloom annually for a long time.
