Kidney Mite On Currants: Control Measures, Preparations, Folk Remedies

The currant bud mite (Cecidophyopsis ribis) is a four-legged microscopic insect that belongs to the genus Cecidophyopsis of the family Eriophyidae (Trombidiformes). This pest is widespread in Asia, Europe and Australia. It can be found in areas with gooseberry or currant bushes.

The insect causes damage to buds, which significantly reduces the leaf mass of the shrub and markedly impairs stem development. In addition, this pest is a carrier of a viral disease called "terrapins".

It also causes rebirth of generative organs, causing the shrub to stop forming berries.

Peculiarities of the bud mite

The bud mite has a white worm-shaped body. Males reach up to 0.15 mm in length, females are larger at about 0.3 mm.

The head ends with a mouthpiece similar in appearance to a wedge-shaped trunk. The pest has 2 pairs of legs equipped with pinnate bristles. Elongate-oval larvae have light coloration. The bud mite can harm gooseberries and black currants, but it can also settle on white and red currants. Over the winter, the mites climb into the buds.

A single bud may contain 3,000 to 8,000 animals, and large buds may contain 8,000 to 30,000 animals. Those buds with pests inside look more bulging and larger. In early spring, they increase to pea-size and look like small cabbage heads, with deformed leaves sticking out. Those buds with not too many pests cannot be distinguished from healthy ones, which is the main difficulty in the fight against kidney mite.

Pest spreading occurs with the wind, together with seedlings, thanks to birds and various insects.

Female life span is 20-45 days, with one being able to lay 5-100 eggs. Eggs take 7-15 days to develop, and larvae take 7-30 days. The first mite generation appears at the very end of currant blossoming. During one season the mite is capable of giving 5-6 generations of offspring: 2 in spring time and 3 in summer-autumn period.

Control measures

In order to protect your garden from the bud mite, you must not forget preventive measures.

When purchasing seedlings, conduct a thorough inspection of their buds to make sure you don't bring a colony of pests along with them. Phytoncides, which are contained in garlic and onions, can repel the pest, so these crops are recommended to be planted between the rows of currants. However, in this case, in the fall onions or garlic are not dug up, but left in the ground for the winter.

If you decide to propagate a currant bush with a cuttings, then cut it from a plant that is fully healthy. Experienced gardeners recommend, disinfect the cuttings, for this they are placed for a quarter of an hour in warm water (about 45 degrees), in which first add indolylmalic acid (0.

5 grams of means per bucket of water).

If the buds in which live mite on the bush, very little, then they can be severed by hand and destroyed by fire. If the pest is in almost every bud, then the above-ground part of such a shrub is cut down and destroyed, and the stump that was left in the ground is capped. After a while, new stems will grow. To avoid such pruning, it is recommended that each shrub be thoroughly examined annually in the spring, during which all buds that look suspicious are cut off and burnt.

Chemical preparations

To get rid of the bud mite you should start fighting it already in spring time. For this purpose, before the sap starts to flow, the currant bushes and ground near them are sprayed with Nitrafen solution (30 grams per 1 liter of water) as a preventive. As soon as the inflorescences and leaves begin to form, 3 treatments of currants with an interval of 7 days, for this purpose use biological pesticides against pests, such as Bitoxybacillin, Actofit or Fitoverm. These sprays will only be effective if the air outside is warm to 5 degrees or higher.

If the weather is cooler or overcast, then treatment should be postponed.

While pests are moving from diseased buds to healthy buds, they can be killed by spraying the bush with ISO (lime-sulfur decoction), Carbophos or other sulfur-containing products. At the time the buds are exposed, the bushes are sprayed with ISO solution (2%) for the first time. Repeated treatment is carried out after 10-12 days or as soon as the currants blossom, but in this case, the solution must be one percent. In the same way and at the same time, bushes can be sprayed with a solution of colloidal sulfur (10 grams of agent per 1 liter of water).

The following acaricide preparations can also be used to kill the mite: Endidor, Vertimek, Oberon, Nissoran, Apollo or Neoron. When spraying, try to ensure that each bud and branch of the currant bush is well soaked with the solution.

Bud mite on gooseberries

Since gooseberries are a close relative of currants, the bud mite also settles on them. Both preventive measures and chemical preparations used in the fight against the insect are the same as in the cultivation of currants, namely: inspect seedlings before purchase, in early spring check all the buds on the shrub, break off and destroy those that have caused suspicion, plant garlic and onions between the rows, and in case of total pest infestation, cut and burn all the stems. As for pesticides, you can use the same products for treating gooseberries and at the same time as for spraying currant bushes.

It is also noticed that bushes doused with hot water give a richer harvest.

    Its fruits are medium sized, oval in shape, and have a sweet and sour taste and firm skin. A disadvantage of this variety is that it requires frequent watering.

  2. Selechenskaya. A versatile early maturing variety with high productivity and resistance to frost and drought. This variety combines all the advantages of currants as well as gooseberries.

    Its large, glossy black fruits with thin skin have a sweet taste and weigh about 5 grams. It is very resistant to kidney mite.

  3. Kipiana. This medium-late variety is resistant to both powdery mildew and bud mite. The almost black rounded dessert fruits have a sweet-sour taste and medium size.

  4. Yadrenaya. This late maturing, high-yielding variety is very popular with gardeners. Its cherry-sized, oval-shaped fruit weighs about 8 grams and has a refreshingly sour taste with firm flesh. They are very hardy against pests and diseases, but require systematic pruning.
