What phalaenopsis are sick with

"Prei monituse, prei minituse" - he who is forewarned is armed.

In this article we will tell you about the possible diseases of the most popular orchids - Phalaenopsis. What phalaenopsis are sick with, what the causative agents of the disease look like, and, most importantly, how to save a sick orchid, read on.

 Root rot

Phalaenopsis infection with rot pathogens such as Naevala perexigua and Microthyriella rubi manifests itself in the appearance of black convex spots on the roots. Can be added with new specimens in your orchid collection. The disease spreads through the air and through water for irrigation.

Root rot control measures are to isolate the infected plant, remove all parts affected by the pathogen, and treat with a systemic fungicide, which is used to combat root rot.

Mites

The plant is affected by spider mites and flat mites, thrips and bedbugs.

When phalaenopsis are infected with a spider mite (Brevipalpus californicus) and flat mites (Tetranychus cinnabarinus, T. urticae and Tenuipalpus pacificus), a silvery bloom becomes noticeable on the leaves. A change in leaf color is an alarm. During this time, the population of these pests can already reach a huge amount. Ticks settle on the inner side of the leaf along the midrib, where even the pros do not often inspect the plants. Moreover, phalaenopsis have juicy leaf blades, which are mechanically easily damaged anyway.

Temperatures within 22 ° C and dry air contribute to the favorable spread of pests. During a bite, spider mites secrete a substance into plant cells that dissolves their membranes. The juice that is secreted at the same time serves as food for the ticks. Air enters the cavities formed on the leaves. Therefore, the color of the leaves changes. Later, a spider web appears. Damaged leaves dry out and fall off.

Flat ticks do not form cobwebs. Symptoms of damage to the plant are the appearance at the base of the leaves of white and then red blooms, which do not disappear when held over the leaf with a cotton swab or napkin. This is the actual accumulation of ticks and the places of their bites. In addition, these types of mites are carriers of various types of fungal diseases.

A similar plaque appears when phalaenopsis is affected by thrips and bedbugs, only more intense.

To combat ticks, the affected plant is washed with a solution of laundry soap. In this case, it is important not to flood the soil, since with a large amount of soap solution, the acidity of the substrate changes. And this is of no use to us. Then the humidity in the dwelling is increased. You can cover the potted plant itself with plastic. With a slight infestation by ticks, this will be enough.

If it was not possible to get rid of the pests in this way, one cannot do without the use of chemistry. Actellic, phytoverm, thiophos, neoron, etc. will come to our rescue. It is advisable to purchase drugs recommended by the current list of pesticides specifically for the fight against ticks. Ticks have the ability to multiply quickly and can develop immunity to one of the drugs within a short period of time. For successful pest control, alternate acaricides.

Among the folk remedies for combating ticks, rubbing the damaged areas of plants with medical alcohol should be noted. You can also wipe it with a pharmacy tincture of calendula. But so delicate so as not to cause burns to the leaves.

If you fell in love with these plants, which are striking in their color of flowers, such as phalaenopsis, then you should know both preventive and exterminatory measures to combat diseases and pests.

Do not let these problems shock you. We are all sick. You only need to notice the symptoms in time and react to them correctly. And the luxurious, blossoming branches of orchids will become gratitude for your care and love.
