Diseases of Impatiens
Impatiens, or Ivan wet – a very popular houseplant that has long cultivated in the home. It is beautiful and constantly blooming, always looks elegant, and it does not require complex care. But before you start growing plants, it is necessary to understand its features and requirements, diseases and pests had come in, what are the measures of treatment and prevention. If you do not follow basic rules of care, and they each plant their own, will die the most unpretentious flower.
Why hurt Vanka wet? First of all, let us remember that Impatiens growing in the home — water-loving plant. Its stems and leaves are more than half water, it likes high humidity and moist soil. And the water, as you know, the basis of life, not only for humans and plants, but also for pathogenic bacteria and insect pests.Diseases of Impatiens
Therefore, water care little wet must be clean and warm. The pot must make a drainage hole and a drainage layer, and the soil should be loose, breathable and moisture. For disinfection of fertile soils it is possible to add a bit of charcoal, it can help prevent the development of putrefactive bacteria and fungi. Thanks to these measures and proper care, the flower will be more robust, and deal with its diseases and pests, if they do appear, will be much easier.
Problem plants Diseases and pests of Impatiens)Diseases and pests of Impatiens
Name the main disease of Impatiens, and methods of dealing with them at home.
Mosaic Vanka wet or balsam – attacks young leaves, they have yellow spots and they begin to deform. Spots expand, the yellowing will spread to the stems, their striking unilateral necrosis. The leaves turn yellow completely, will begin to dry, but will not fall off. And the plant will stop developing and will die.
The mosaic virus is spread by insects – it might be mites or thrips, they should be destroyed. So the flower treatment of this disease is useless, therefore, great attention should be paid to preventive measures, improve care, and sometimes spray the plant with insecticides.
Grey rot – a fungal disease affecting leaves and stems of the plant. Brown spots first appear on the leaves, but gradually spread to the stems and the whole plants. The next stage of the disease – the appearance of grey patches of fungal spores. So the result is deplorable – plant death.Diseases of Impatiens
And the disease is not spread mites and thrips, and pathogenic bacteria that enter the flower from contaminated water or soil. The disease can develop due to hypothermia or freezing of the flower, due to drafts, cold water and low temperature in the room.
As is known, the disease is easier to prevent than to deal with it, so adjust the care of the flower. Water for irrigation should be warm clean, from time to time to prevent watering the plant with a weak solution of potassium permanganate. You need to create a normal temperature, and often ventilate the area in which the flower, but to avoid drafts. Maintain the purity of the air, because the dust in high humidity – the perfect breeding ground for various bacteria. When feeding Vanka wet, try to make so that the fertilizer does not get to the leaves.
Grey rot is a dangerous disease that can be fought. If you notice spots on the leaves, cut them and transplant the plant to another soil, sprinkle an infusion of garlic husk or fundazol.
Bacteriosis causes watery spots on leaves and stems. The spots eventually turn brown, spread across the leaf surface, they are becoming more as a result, the flower dies. If the sheets appeared these stains, remove them immediately until the disease has spread to the whole flower. Healthy part spray Bordeaux liquid, or preparations containing copper.
Sometimes struggle with bacteriosis is very difficult, the disease spreads very quickly. To prevent the ingress of bacteria on other plants, isolate Impatiens, or destroy it.
Bacteriosis develops in infected soil can get to the plant with dirty tools and dirty hands. Good conditions for the emergence of the disease are excess moisture and fertilizer in the soil, as well as high temperature and polluted air.
Powdery mildew is another disease that affects the balsams growing in the home, even with good care. In this disease on the leaves appears white plaque, which can spread to the entire plant. Diseased leaves are removed, the healthy parts are sprayed with a solution of soda ash prepared at the rate of 2 grams of soda in 1 litre of water. In addition, against a white plaque help – copper-soap solution, or bayleton, a solution which is prepared according to the instructions.
If Impatiens are beset with powdery mildew, so you need to change the care – often ventilate the room, to adjust the schedule of watering and fertilizing to ensure the proper and adequate lighting and normal air temperature.
As you know, the rain on the leaves of Impatiens appear drops of sweet liquid, which attracts insects and mosquitoes and flies, which themselves do not cause the plant harm, but are carriers of pathogenic bacteria and viruses. This feature complicates caring for potted balsams, because their nature cannot be changed. Therefore, Impatiens often than other plants must be treated with insecticides, applying them according to the instructions.
What insect pests attack on flower? The list includes aphids, root aphids, spider mites, whiteflies. We will describe them in detail.Diseases of Impatiens
The aphid sucks SAP from the leaves of the balsam, that’s why they are deformed and cease to grow. With extensive lesions of the Bush aphids are not possible photosynthesis and normal plant development, as a result, it may die, or cease to bloom.
The salvation of the aphids are the infusion of tobacco, dandelion, onion peel, wormwood, Sophora, tansy, marigolds, Sophora, yarrow.
Moreover, plants treated with the soap-ash solution, a solution of potassium soap, pyrethrum, ashes, sulphur or tobacco dust. Chemicals FAS, Decis, Karate, Hostaquick, Aktellik, Fitoverm – they are used according to instructions. When processing flower the earth in the pot should be covered with polyethylene.
Root aphids or root bug is a dangerous pest of white color and elongated shape. The damage this aphid is that it sucks the juices from the roots, it is not immediately notice. But on the walls of the pot visible nests aphid in the form of a white «cotton» plaque. Reflects the disease and the appearance of the plant, it begins to weaken and wither. Root aphids reproduce in dry soil if care little wet is not right, and the glaze – not a regular.
These pests are easily detected during transplantation and examination of the root system. Badly damaged, shrunken fragments of the roots are removed, treated them with insecticides, are soaked in a solution of tobacco, tansy or chemical insecticide. The soil in the pot completely change and wash the pot with detergent. To prevent root aphids plant in the spring and autumn watered with solutions of insecticides.
If the roots are badly damaged, it will be difficult to provide water and nutrients to the lush Bush, it will have to be cut. Cuttings can be used for breeding.
Spider mites are another pest of balsam. If the flower is attacked by spider mites – the struggle will be long and hard. The fact that the ticks are spreading rapidly in the area, creep into all sorts of cracks and crevices, hiding in pots with other flowers, and things near the flower, and bring them very difficult.
At first, spider mites are almost invisible and does not show. He settled on the back of leaves, begins sucking the juice and gradually multiply. If the plant has appeared on the web, then the mite has spread far enough and the disease is in advanced form.
What to do if the Impatiens attacked by spider mites? In the first place to inspect other plants, possible pests and occupied them. Then you need to isolate the flower from other plants and spray his chemicals. To disinfect the surface of the sill or shelf on which stood a flower, perhaps a mite and there.Diseases of Impatiens
Spider mites quickly gets used to chemicals, so every 4-5 days the plant is treated with a new drug. It can be Nissorun, Sunmit, Aktellik, Apollo, Dichlorvos, Kiron, Ortus. After processing Impatiens covered with a plastic bag to enhance the effect of chemical preparations — this simple technique can be used against other insect pests.
As you can see, the fight against spider mites is expensive, since a whole set of drugs is not cheap. Therefore, growers think it’s right to get rid of the flower, the affected spider mites.
And recorded spider mites in the room along with clothes, vegetables and fruits, all other things in which the insect can hide. It’s very small insects, up to 1 mm.
For the prevention from time to time treat Impatiens insecticides, often inspect it to identify mites and other pests, correct care of it.
Whitefly – an insect harmful to Balzaminov, and some other houseplants. It is a small white moth that can reproduce themselves for 30-40 days. Whiteflies lay eggs on the reverse side of the leaves, appear from the eggs the larvae, which occupy all the plant and begin sucking the juice out of it.
Gradually the skin of the larvae harden so that they become immune to insecticides, so the whitefly is not easy. The plant must be processed several times with an interval of 5-6 days.
Under the influence of whitefly larvae balsam leaves lose color, turn yellow, wither and fall off. As a result, the plant may die completely.
But the damage from whitefly does not end there – the leaves, the insect secretes a sugary liquid, which develops a sooty fungus that weakens the plant. In addition, a malicious butterfly carries bacteria and viruses from flower to flower, and can infect all the flowers on the windowsill, in a greenhouse or in a greenhouse. It affects not only the balsams, but also ferns, fuchsia, pelargonium and other plants with soft leaves.
Care for Impatiens becomes more difficult. Collecting butterflies with your hands, but they can hang Velcro, or sticky leaves. Glue traps are easy to make on your own – a sheet of plywood, cardboard or hardboard painted in yellow, smeared with vaseline, castor oil or rosin with honey.
Eggs and larvae from the leaves can be washed off by the shower, it is necessary to keep the jet of water falling on the leaves on both sides.
Growers are advised to frighten the butterfly Bush, and collect them with a vacuum cleaner, but this method does not allow to completely get rid of pests. The most reliable method of controlling and prevention is the treatment of plants with insecticides, or infusion of the pounded garlic.
