I never thought that this would happen to me, but you can “congratulate” me: one day was not a beautiful day on the leaves of phalaenopsis, I saw uninvited guests. Unfortunately, at work was a terrible zapara, and had to postpone the "disinfection" of flowers for the weekend.
As you have probably already guessed, in a few days I had to treat not one, but all the flowers growing on that window sill. So my very first advice on fighting the shield is: do not delay this fight for a single day. Then the work will be many times more.
What kind of pest is this?
Small insect up to 5 mm in length. Its back is covered with a wax-like shield, which may have a different shape depending on the type of pest.
The females are large, “nailed” to the leaflet. May lay eggs or larvae. Males are smaller, sometimes fly.
Both insects and their larvae drink the sap of the leaves, thus harming the beauty and vital activity of the plant. Moreover: gnawing through the holes, they make these "passes" for other pests - fungi.
Fortunately, on the windowsill the shield can be seen less often than in the garden. But some typical garden insects can be considered your enemies.
Pests of trees and shrubs
- Rose Shchitovka. It spoils not only roses, but also wild rose, strawberries, strawberries.
- Pine spindle-shaped. Conifers are afraid of this pest - yes, there is juice in needles too.
- Tuevaya, it is juniper. It looks like a cypress. What prefers can be understood from the title.
- Californian. Harm to many cultures, most of all likes to live on apple trees. It spoils not only the leaves, but also the fruits.
- False Californian. Already found all over the world. In the garden, the larvae can winter without any problems.
- Red Orange Pest of many plants, including citrus and roses. Can live in the fruit. It nibbles everything: not only the leaves, but also the stems, the buds, the flowers, the fruits.
- Orange He likes to feast on the juice of the leaves of any citrus fruit, so that it can well attack the decorative lemon. Also, do not give up laurel.
- Apple. He loves not only apple trees, but also bushes, and even herbs.
Personal enemy of all orchids. Collects juice not only leaves, but also branches of subtropical and tropical plants.
Often lives in greenhouses of our country, so even if you buy a plant from professionals, it’s not a fact that it will not be infected by this “sweetest” creature.
Another harmful inhabitant of greenhouses.
Moreover, it is difficult to discern this insect, since it often hides under the pieces of the bark of its “victim”.
Prefers subtropical and tropical plants.
These small villains do not have a wax "shell". Larvae and eggs protects the skin of the female. That is, if you lifted the midge from a piece of paper, and she withdrew along with the shell, you have a false shield in front of you. If the "plaque" was removed, and the insect remained on the leaf, it is a shield.
There are a lot of scammers too. I will show photos of those with whom lovers of flowerpots deal.
- Soft Parasitizes on many home flowerpots (from orchids to begonias). It can be recognized by a spray of sugary liquid not only on the leaves, but even on the window.
- Olive. The enemy of bush plants, may encroach on citrus fruits. The females have a brown semi-circular body, the larvae are yellow with two tails.
What plants to taste this insect
- orchids (any),
- rubber plants (all species of this plant),
- room pineapples and other bromeliads,
- palm trees (and most of all these pests love to gnaw fan leaves),
How to understand that a plant is infected
The leaves begin to "decorate" with brown (less often just light) scales of a rounded shape. They can be removed from the sheet, but with difficulty. This is a “classic” scythe.
The leaves turn brown, and if they shone before, the gloss is gradually lost. The surface is covered with a sticky coating.
Looking carefully, you can see the brown-red or icteric points - the place of insect bites. This is the job of a false shield.
But all kinds of harm are the same:
- the young shoots of the plant dry out
- young leaves generally stop growing,
- leaves turn yellow, begin to fall off,
- the plant dies (advanced stage).
- Carefully detach the bitten leaves and twigs. Or moisten a cotton pad in a soapy solution or insecticide (more on them below) and wipe the villains, and if they bite into the stem, scrape them off with the blunt side of the knife.
- Send the diseased pot to the quarantine window sill. All the other flowers (even growing on other window-sills), inspect as the most strict inspector.
- Wash the window sill, as well as the frame with an insecticide or the same soap.
- Spend preventive spraying (washing) among the other vases.
- For a diseased plant, replace the top layer of the soil with a fresh one.
- If the plant can take water treatments (say, this is an orchid), send it to a hot shower.
- When the leaves dry, process them in one of the ways described below.
Allergy sufferers, as well as parents of small children, who are afraid to even bring chemistry to the house, first of all remember them.
It's simple: take a cotton swab, moisten with water (or even better - vodka, alcohol) and wipe the leaves with it.
In addition to simplicity and low cost, this method allows you to take a break for an hour, and then resume processing the flower - you cannot do this with purchased poisons.
But there is such a method and disadvantages:
- it doesn’t work right away - it kills something, but their eggs are gone, and you’ll have to wash off the larvae a couple of times,
- some plants may not like alcohol,
- caustic alcohol is better not to wipe young leaves and buds.
These methods are considered cheap, and often environmentally friendly, but do not always help. In addition, the use of caustic substances can harm the already eaten leaves of your decorative pets. I will write more about them than for reference.
- Tincture of garlic. Another option for young parents. However, with garlic caution: after it can burns.
- Tincture of tobacco. Not the strongest tool, but more gentle than garlic. True, it should be combined with a mechanical "erasure" of the shield.
- Soap solution. Probably the most popular way. Simple, cheap and not scary if the child decides to help. But remember: the remnants of soap on the leaves - not a joy for a flower, so after three hours arrange a shower plant or just wipe the leaves with a washcloth with clean water. In addition, soap is not a poison, so this treatment will have to be repeated.
- Vegetable oil. This method is dangerous because it creates a film on the surface of the sheet. Shchitovka gasps under it - true, and the plant too.
- Kerosene. A stronger remedy. But it can burn tender leaves (especially young ones).
And still the shield can be driven away with the help of tar soap. Everything is simple to disgrace. Video review with the results of such a wash - here:
Leave the solution on the plant to dry. Wash window sills and glass with the same solution (or just soap). When the plants are dry, air the room thoroughly. It is not necessary to rinse off flea and tick products, if the smell remains, then the emulsion can be washed off the next day.
Usually, one treatment with flea and tick treatments is sufficient. But if the defeat was very strong, you need to repeat the treatment after 7 days.
Spray flea and tick spray into the bag as thoroughly as possible, for example, with ‘Bolfo’ spray. We do not recommend the use of dichlorvos - it has a very short-term effect and high initial toxicity. So, put the spray in the bag and press the sprayer for 4-5 seconds. Carefully tying packages, leave it for a day. Pests die from choking.
It is best to carry out all the procedures on the street (take out the plants in the boxes, make up the pelvis) or on the balcony.
