Gooseberry. Diseases and pests of northern grapes

An unpretentious perennial bush is grown in Russia from time immemorial. Gooseberry berries are delicious and very useful, and thorny branches allow the use of culture as a hedgerow. With good agricultural technology, gardeners can receive up to 15 kg. Berries from one bush, so can be prolific gooseberries. Diseases and insects significantly reduce the yield, so it is important to ensure the plant good care during the vegetative period. It consists in loosening the soil, timely watering and fertilizing, and also in pruning and removing the affected branches and berries.

Diseases and pests of gooseberry

Most plants suffer from pathogenic fungi, but they are also affected by viruses. It is necessary to carefully examine gooseberries - diseases usually begin with lesions of leaves.

Spheroteka

More commonly known as American powdery mildew, it can kill a plant in a few years. In spring shoots and leaves start to cover a white coating, which later darkens and becomes like felt. It is difficult to defeat the disease: the fungus hibernates directly on the shoots, and the spores remain active in spring and summer.

Control measures:

• To acquire gooseberry-resistant in the nursery;
• Diseases can be prevented by applying bacterial methods: repartition manure pour water in a ratio of 1: 3, insist 3 days, dilute with two parts of water, drain, process bushes;
• Removal of diseased branches in spring and autumn, burning of sick berries and plant debris;
• Spring treatment of the tips of shoots with hot water or spraying with 1% solution of copper sulfate ;
• Treatment of bushes with colloidal sulfur before and after flowering, the introduction of potassium and phosphorus fertilizers in the second half of summer.

Anthracnose

Disease, rapidly developing in conditions of high humidity. Brown stems begin to appear on the stems and shoots. Gradually spreading, they cause death of the leaves. The plant is weakening, the yield is decreasing.

Control measures:

• To keep the soil clean from weeds, in the beginning of spring and in the autumn to conduct a digging of the earth under bushes;
• In the spring, before the dissolution of the kidneys, spray the branches and soil with copper sulfate or nitrafen. At the first signs of anthracnose, treat Bordeaux fluid, but you can do it no later than 1 month before picking berries or 10 days after it.

Rust columnar and goblet

Is showing itself in June. These are externally similar diseases of gooseberries (the photo can be seen on the right), their appearance is caused by the neighborhood with sedge grasses and conifers. The outer part of the leaf plate is covered with yellow spots, and orange felt pads appear on the underside.

Control measures:

• Plant bushes away from planting pine and cedar and mow sedge near the place where gooseberries grow - diseases can be avoided;
• Treatment of bushes with biofungicides or Bordeaux fluid during the period of foliage blossoming, with bud bud separation and immediately after flowering.

Pests

There are many harmful insects who are not averse to sharing their harvest with the gardeners.

Gooseberry bud aphid

He prefers to settle on young plants. It attacks fresh leaves, which "attacks" begin to curl and dry up. Females lay the larvae on the crust for the winter, and in the spring an increased colony can spread throughout the garden.

Control measures:

• Spraying with "Carbophos", "Aktellikom", "Khostavkom";
• Method without the use of chemistry - treatment with mustard white infusion .

Gooseberry sawfly  

Females of this pest lay their eggs on the underside of the leaf, and within a week caterpillars leave them. They swiftly devour foliage, and after 3 weeks go to the ground for pupation. For a season 2-3 generations of sawfly can harm a plant.

Control measures:

• Tearing of diseased ovaries, removal of fallen leaves, loosening of soil;
• Treatment with insecticides at the time of the dissolution of the kidneys and after flowering.

Gooseberries

The most common pest, annoying the plant. One butterfly can lay flowers up to 200 eggs. The newly born caterpillars bite into the resulting ovary, trying to get to the seeds. The habitats of the sawfly larvae are covered with cobwebs. Affected berries, not having developed, acquire a ripe appearance, then rot and wilt.

Control measures: destruction of spider's nests, treatment of bushes with insecticides.
