Pests currant and gooseberry
CECIDOPHYOPSIS RIBIS - the scourge of black currant.Red and white currants are suffering from it often.The presence of the tick indicate large swollen buds, similar to small blond heads of cabbage, which can be found in the autumn, after leaf fall or early spring.The mite is very small (0.2-0.3 mm), similar to a light crustacean with two pairs of legs.In the spring, as soon as the air warms up to 5 ° C, the females begin to lay eggs in the same kidney.By the time of formation at the currant flower hands the number of individuals in one kidney may reach 3-8 thousand.Then, most ticks go outside, climb the twigs and colonize new buds that are dying like the first.In addition, the mite spreads a dangerous viral disease - terry, causing infertility currant bush.
Control measures. Use only healthy planting material.If there is no firm confidence, the cuttings before planting is disinfected by immersing in hot water with a temperature of 45-46 ° C for 13-15 minutes or 3 and held in Georgian tea infusion (
Proper care will increase the resistance of plants planting.To repel ticks practiced planting rows or groups among the currant bushes onions or garlic.At low infection bushes gives a certain effect spraying in the period of extension of inflorescences freshly prepared slurry of garlic (50-100 g pounded cloves of 10 liters of water).At a higher degree of settlement (5-10% kidney) using sulfur preparations spraying method (colloidal sulfur - the rate of 40-100 g per 10 liters of water), but not to be exposed to drugs gooseberry bushes avoid defoliation.
autumn after leaf fall or early spring (before bud swelling) should pluck swollen, damaged kidneys or remove the entire tick escape, cut it to the ground level.
currant bud moth, damaging the buds and berries of all kinds of currants, red and white preferred.Hibernate gusenichka (2 mm) at the base of the bush cocoons under peeling bark or stumps left after the cutting of irregular branches.In the spring they went up the shoots, penetrate into the kidneys, destroying them.Before flowering currant the caterpillars go into the top layer of soil for pupation.At the time of the formation of the ovary appear butterflies, which lay their eggs in the flesh of green berries.Hatched larvae eat away the seeds.
Control measures. autumn cut at the very root of dry twigs and stumps, destroy all plant residues.If in the previous year mol destroyed up to 3% of the kidneys, in the spring at the time of bud swelling (at a temperature of 13- 15 ° C) to process the bushes with a decoction of tobacco onions or mustard extract (100 g per 10 liters of water) or soap and ash solution.At a higher degree of infection to apply the 5 ^ th kinmiksa emulsion (2.5 ml per 10 liters of water).Late treatment with unacceptable, so in this case it is firstly ineffective and, secondly, leads to the death of riders - moth pests.
currant steklyannitsa - is wilting and drying of individual branches in the bush currant developing well.If you cut a branch, it is clear that the core will drive and looks like a wormhole with a sleek black walls.Where you can find white or pinkish caterpillar with dark head.Adult caterpillars reach a length of 2-2.5 cm. Living 2 years.For the second year in late spring they gnaw a hole to the outside and turn into pupae and then into butterflies, which lay their eggs on the bark of twigs, usually about cracks.Wilting and drying branches usually occurs at the end of flowering or later - at the beginning of ripening gooseberry and currant berries.
Control measures. With proper care is less risk of damage steklyannitsey bushes.Early spring pruning is especially important with the simultaneous removal and immediate burning of cut branches, which may be a caterpillar.Large sections should cover up garden pitch.
careful not to damage the bark, so as not to create conditions for laying eggs and butterflies.
Leaf gall aphid - a frequent lodger red and white currants.In the spring on young leaves stand out noticeably swelling red - it galls.On the underside of the leaf galls in these can be detected and their perpetrators - small yellowish-green larvae of aphids.Damaged leaves wither and fall off.Of the natural enemies of aphids gallic widespread eating its predators: ladybird, lacewing larvae, flies, flower flies, and bugs-antokorisy.
Control measures. first leaves with symptoms of redness is better to cut and destroy.Keep the reproduction of the pest will spray the bushes with infusions of tobacco dust, tobacco, celandine, dandelion, chamomile, sorrel, tansy, yarrow with the addition of soap.When using herbal infusions should be thoroughly wet the underside of the leaf.Before flowering plants treated with the drug-M of the spark caterpillars (5 ml in 5 liters of water).When planting garlic near the currant tomatoes and onions reduced the population of aphids bushes.
Most currant aphid affects mainly black currants, but also found in other types of currants and gooseberries on.The leaves, which feed on aphids, pale, twisted, going lumpy, shoot tips are bent and do not grow. Control measures. See. Gallic aphids.
gooseberry sawflies (and the pale yellow) damage leaves gooseberry, red and white currants.They differ mainly in the size and color of the body.In the yellow sawfly adult insects reddish-yellow, from the pale - black with light spots.Larvae like caterpillars, but have 10 pairs of legs.And lie-nogusenitsy first have a length of 18 mm, they are bluish-green with a black beard, girl children, the second - is smaller, up to 10 mm, single-color, green.Eats leaves, leaving some veins.They hibernate in dense cocoons of the larvae under the bushes at a depth of 5-10 cm. Control measures. Shallow digging of the soil in the fall and spring.In spring and summer it is recommended to shake the larvae from the bushes on the mat.If this is not sufficient, the spark are sprayed (one tablet per 10 liters of water) bitoksibatsillin (80-100 g per 10 liters of water) Lepidocide (20-30 g per 10 liters of water).In their absence use infusions of wormwood, tobacco, tobacco, garlic.Effective fosbetsid (5 ml in 5 liters of water).
gooseberry Moth hearth has spread.Caterpillars with five pairs of legs, a fairly large (30-40 mm), bright with characteristic black spots on the back quadrangular. Control measures. See. Sheet sawfly.
gooseberry moth as pupae overwinter in the spider cocoons in the upper layers of soil under a bush.Spring chrysalis turning into butterflies, which after a while lay eggs in the flowers of gooseberries and currants.Hatched larvae penetrate into the ovary and they eat away.Going from berries berries, caterpillars braid their cobwebs. Control measures. spend the autumn digging the soil and hilling bushes to a height of 10 cm. In the period of formation of ovaries tobacco plants are sprayed with infusion or decoction of wormwood 2-3 times every 5-8 days.Damaged berries were collected and destroyed.
