History of cherry plum Kuban comet

Grade Kuban comet bYyl withdrawn G.V.Eryomina and S.N.Zabrodina at the Crimean Experimental Selection Station of the All-Russian Research Institute of Plant Industry named after N.I.Vavilova. He was born thanks to the interbreeding of plum Skoroplodnaya and Cherry plum Pioneer

.First, in 1977, this variety was taken for state tests. And after 10 years it was entered into the State Register in the North-West, Central Black Earth, North Caucasus and Lower Volga regions.

Cherry plum Kuban comet appeared as a result of crossing the plum of Skoroplodnaya and Cherry plumbush. The trees have a gray color and short branches. Green leaves are glossy and not pubescent. Color buds may be small or medium in size with white petals.

Advantages and disadvantages

The Kuban comet has its advantages, here are some of them:

  • fruits are large,
  • is high yields,
  • is quick, grows, and is now a good seed,
  • is partly self-fertilizing,
  • is resistant to disease,

But the variety is not perfect, it also has its drawbacks:

  • bone is very badly separated from the pulp,
  • to ensure large size of fruits, they need to be cut off, leaving them more space next to each other,
  • fruits ripen unevenly.

Planting rules

Trees of this class are planted in early spring or early autumn .First you need to choose the right seedlings. It is best to select them with a closed root system.

Saplings of cherry plum Kuban comet

A good sapling has the following characteristics:

  • height from 1 to 1.20 meters,

Landing Stages:

  • A bit of earth is poured into the hole in the form of a small hill.
  • Insert a wooden stick.
  • Root the neck is located 6 cm above the ground.
  • Ramming the ground.
  • A sapling is tied to a fixed stick.
  • Watered with 2 or 3 buckets of water.
  • At the end of the top piled chips.

In the case of planting several trees, you need to keep a three-meter distance between them.

Care of the Kuban comet

This variety loves moisture, so it must be watered in addition during the growing season. Do it in June, July and September. One tree requires up to 40 liters of water. After watering, be sure to pour chips.

A tree is cut or shortened each year by cuttings and thinning the crown. Most often they make a bottomless or cup-shaped form.

The main pruning is done in the spring .During this period, a crown is formed and frozen and damaged branches are cut off. In the autumn period, dry, sagging and diseased branches are sawn off. Summer pruning is carried out with great need, while cutting off the young shoots that grow inside the crown.

The site of birth of the infection is sclerotia and conidia, which are found in the soil and plant residues .In the case when the disease affects the Kuban comet, branches begin to wither and a brown tint appears on them, and small gray growths appear on the bark and fruits. The fruits begin to rot.

Gray rot( moniliosis) cherry plum Kuban comet

To destroy gray rot before the flowering trees are sprayed with copper sulphate and Nitrofen, which need to be processed wood and soil. And also after flowering, Captan and Kuprozan are used.

To prevent disease, trees should be sprayed with such preparations in early spring:

  • 1% bordovskaya liquid,
  • hand-boron for affected fruit,
  • whitewash.

Brown Spot

Brown Spot, or it is also called leaf mold, is also a fungal disease. Sometimes it can kill around 50% of the crop. This disease is characterized by the appearance of brown spots with dark rims on the leaves, which have a black dot in the center. Over time, the leaves dry out and fall off.

Cherry plum Kuban comet hit by brown spot

Trees against brown mold need to be treated with 1% with burgundy solution as soon as the buds begin to bloom and chlorine oxide 2 or 3 weeks after fading.

Preventive actions that will help prevent the disease are as follows:

  • need to remove damaged branches,
  • before buds are dissolved, you need to sprinkle the tree and soil with 1% copper sulphate.

Rust

Another type of fungal disease is rust. With this disease on the leaves appear rusty stains, which eventually turn into dark pads .Rust wood is treated in the second decade of July. You can use Aktofit. They are sprayed with trees 2 times with an interval of 2-3 weeks.

To prevent rust from attacking the Kuban comet, preventive measures should be taken:

  • 3% urea solution is sprayed on the tree in early spring,
  • when the leaves fall, scrape and burn it.

Goverment

It is dangerous that it can slow down or stop the growth of a tree, and eventually even destroy it.

Govering of Cherry Plum Kuban Comet

Godetreatment is not a fungal disease. The reasons for its occurrence may be mass. Here are the most common of them are : , because of the fact that the company paused,

  • received the burns from the sun, and the
  • failed to prune the . application of fertilizer and watering,
  • infection of tree with bark beetle.
  • When you look at the tree, you can see gum( protrusions of amber resin) on its branches; this is evidence of the tree being affected by this disease. It is possible to process the Kuban comet from this disease throughout the entire season. After pruning, be sure to put petrolatum on slices. And also cut gum growths. The place where they were was disinfected with a 1% solution of copper sulphate and covered with a non-brut putty.

    In order not to have to fight against cumulative activity for a long time, it is necessary to carry out such preventive measures. :

    • soil acidity should be neutral,
    • strict adherence to the terms of fertilizer,
    • to avoid over-wetting.

    In the case when there is a gum therapy on the tree, and horizontal passages with a diameter of 1 to 2 millimeters are seen on the branches and the trunk, this means that the sapberry has settled on the tree.

    A fruit sap is a very common pest of cherry plum

    Before the egg laying period, females eat tissue at the base of the kidneys. When the larvae appear, they absorb the bark and roots. To destroy these pests, a tree is sprayed at the end of an bloom. The treatment is carried out 2 times with an interval of 14 days.

    To prevent a fruit sap from falling onto the tree, needs to saw off dry branches and immediately burn them .The bark is cleaned of moss and lichen, and also the tree is whitened.

    West unpaired bark beetle

    Preventive measures against the occurrence of these insects are as follows:

    • the affected branches are cut down and burned,
    • if the tree is severely affected by this pest, it is better to uproot and burn,
    • before the tree starts to blossom, it is necessary to process Trihlorolem-5.

    Down Silkworm
