Diseases of the plum and the fight against them, photo to help the gardener
It is possible to grow a plum in the garden and annually harvest delicious fruits, knowing the secrets of agricultural technology. Some plum diseases and the fight against them are described here, and a photo to help the gardener. Any disease is easier to prevent at the stage of care and prevention. It is impossible to eradicate once and for all all sources of disease, they are included in the program of Nature. But people have learned how to restrain, prevent viruses and fungi from entering their garden.
Classification of plum diseases
- fungal;
- bacterial;
- viral.
Improper care can also provoke non-communicable diseases. Consider a photo of plum diseases and the fight against them.
If plum leaves are sore with rust, you need to remove the juniper and anemone from the garden.
Fungal diseases
Fungal diseases are transmitted from tree to tree when foliage is thickened, which does not have time to dry out from rain and dew for a long time. In a warm, humid summer, spores of fungi brought from outside take root in tissues and create a mycelium. A few days - the disease is already in charge, eating fruits and foliage. Examples of such diseases are plum moniliosis, clasterosporium disease, and rust.
Often a tree suffers from more than one, several diseases. Fungicides destroy any fungal diseases; there are systemic drugs. Different substances are used for insect pests and diseases.
Experts consider the most formidable disease to be moniliosis or monilial burn... A symptom of the disease is the instant drying of individual branches. The leaves turn black, but do not fall off, the fruits continue to develop. The infection is introduced into the fruit if there are scratches or wounds on the skin, causing plum disease - the gray rot of the fruit. Spores are transmitted from one berry to another by touching. As a result, the crop is ruined and it will take a long time to eradicate the infection. The fungus lives in fruits, fallen leaves, after overwintering, it will begin to multiply again in the spring.
Another disease that can leave the owner without a crop is marsupial disease, or plum pockets. A sign that the disease will manifest itself is long flowering, a long fruit is poured, which remains green for a long time, turns brown, dries up and falls. Only the fruits are affected.
Viral diseases
Viral diseases are terrible for any plant. Look at the photo of plum viral diseases, the fight against them so far consists in the use of systemic drugs. The disease affects the vascular system, is transmitted by leaf-eating and sap-sucking insects. Sharka or smallpox is a terrible disease for plums. She can go to the tree even from clover. Another viral disease is chlorotic annular leaf spot. In this case, the leaves are lightened, the dried plate becomes in holes, the tree is oppressed. Curly leaves may appear. Any modification of the leaf blade of the seedling should alert you when buying.
Bacterial diseases
Bacterial diseases are caused by microbes and bacteria transmitted with the planting material, tools. Bordered small spots appear on the leaves. The inner part of the plate dries, crumbles, and a clear border is visible from the outside and the leaf around it becomes lighter. The fruits are covered with black and brown spots. Plums become inedible and fall off.
It happens that bunches of thin twigs appear on the branches - a witch's broom. This is mycoplasmosis. An infectious plaque forms on the leaves below.
Non-communicable diseases include gum flowcaused by careless pruning when the tree tries to heal the wound with gum. Therefore, caring for stone fruit trees should be as careful as possible. All of a sudden, the plum can begin to dry out. The reason lies in the close standing of groundwater, freezing or the soil is not suitable for the tree.
As you can see, any of the plum diseases weakens the tree, deprives the crop, and their treatment must be timely so that the tree does not die.
Prevention and folk remedies for combating plum diseases
Prevention of plum diseases consists in choosing the right place under the tree. The soil should be fertile, the plant should receive top dressing and preventive treatments during the period. To get rid of breeding grounds of diseases, foliage from the garden is not used in compost, but is burned. The trunk must be revised after whitening. Keep the trunk circle clean, free of weeds.
There are no recipes for dealing with plum diseases using folk methods, only special chemicals can cope with them. Even preventive spraying in the spring should be done with copper-containing preparations.
Hello. I don’t know who to ask for help. On the plum branches below, growths are orange and dark gray, like an octopus. It looks like an infected plum is about ten meters away. Not visible on the cherry nearby. The plum looks alive, there are fruits, although not much. According to the descriptions, I did not find anything similar. Help me please.
Please attach a photo of the build-up and we will try to help you.
Olga, thank you very much for your participation. The growths on the branches from below can be difficult to see. Yes, I am not a computer expert yet. Thank you in advance. There are already many growths.
The growths are very similar to the scabbard. Try to pick it out. If it's still a scabbard, you will understand right away. After all, it is a living organism. It is possible and necessary to fight the pest. True, the affected area is large and it will take a lot of time and patience. The shield reacts to lubrication with alcohol or vodka. The adhesion to the bark of the tree is weakened. At this time, brush the branches with a brush. Spread oilcloth under the tree to collect and burn the fallen pests. I would like to know the test results.
Olga, thank you very much for your participation. Once again I try to send a photo, but it doesn't work. I'm a bad programmer. The growths from the bottom of the branches are poorly visible. Thank you in advance.
For large-scale lesions, chemical methods can also be used. This will help preserve the tree, but the harvest will have to be sacrificed, since at this time there are already fruits on the branches. Against the scale insects, drugs such as Inta-Vir, Iskra-M, Calypso, Karbofos-500, Bi-58 new work well. It is advisable to do at least 2 treatments at intervals of a week, alternating between different means. The tree should be sprayed from all sides, both above and below. Pay special attention to branches.
Natali, thanks for the advice. I will definitely try to fight. It is definitely a living organism. You can pick out and crush with your fingernail. Just how much vodka is needed !!! Just kidding. But there is no way out.
Water wears away the stone. Moisten a cloth or cotton swab with alcohol and every day, one branch can be cleaned. Of course, this is the case if you want to save the tree. If there is no opportunity or desire to fight, the tree must be cut, doused with diesel fuel and burned so that it does not spread to other trees.
Of course, Natali, I will fight. It is a pity for the plum, very tasty, and labor, of course.After cleaning I will try Bordeaux liquid.
Girls, I want to tell you how today is the first day I collected this shield, if this is it. With a fingernail, and some even with a finger, she picked off the branches. I'm afraid it might be too late. Some of them turn into dust or sand, and some don't, leaving a whitish mark on the tree. Of course, it does not work that none of them fall to the ground, even though they have laid a blanket under a tree. I collected about a fifth part, it's hard, but nothing, I can handle it. Thank you again for participating, the main thing is that it would not be in vain.
You will succeed. The tree will need to be fed in order for it to regain its strength. Treat the soil under the tree with the preparations recommended by Olga. In the fall, after the leaves have fallen, treat with Bordeaux liquid. A whitish trace confirms that the pest is alive.
Good evening. Today I cleaned a fifth of the plum. I'm afraid it's late, some growths are crumbling in my hands, the trail of them is whitish. I would like to believe that it will be possible to save the plum.
What is this disease and how to deal with it? Leaves like warts.
We got a plot with overlooked trees and bushes. Some of them we removed completely, some I would like to leave. There is a yellow plum, the bark of which is covered with some kind of disease, the fruits fall already wormy without even ripening. What can be done with it and by what means, When is it better to do it? Or is it no longer cured and it is better to cut it down?
If the tree bears fruit, you can leave it. After the leaves have fallen off, treat with copper sulfate. In the spring, before bud break, carry out another treatment with copper sulfate. Give the tree some food.
