    Pests of roses.

    Optimal placement of the rosary and the proper care healthy, powerful rose bushes are more resistant to pests, but these intruders are not insured by any garden plant. The rapid spread and multiplication of pests of plants contribute to adverse weather conditions.

    Pests of Roses



    First single pest on plants is hard to notice, so it is important to regularly inspect the roses, to take urgent measures for their early detection and destruction. Should be involved in the garden and to protect the natural enemies of insect pests. This bird garden and numerous residents - lacewings, ladybugs, centipedes, spiders, hoverflies, lizards, frogs, toads and other beneficial creatures that kill pests and preserving a healthy garden.

    To attract mates natural pest plants in a garden variety of flowers and aromatic herbs; garden pond will attract and please also useful garden inhabitants. In the struggle with a variety of plant pests are very helpful to the birds, so I recommend to place far away from the rose garden birdhouse. It is useful to put in the garden plants and seeds they love birds, as well as to feed the birds in the garden in winter.

    Seen on roses single pests often easy to assemble by hand. Gardeners practiced spraying the affected plant pests environmentally friendly products manufactured from plant-defenders. Chemicals as a method of pest control, use only when absolutely necessary, as in the processing plant chemicals destroyed useful garden being harmed soil and human health.

    Talk about plant pests, which are most often found on roses, as well as measures to combat them.

    Thrips - tiny and thin, very elongated body with podvizhnyenasekomye wintering in the soil and on plant debris. In the microscope in these insects distinguishable fringe on the wings and vesicular suckers on their feet, so also called thrips puzyrenozhkami. Thrips lay their eggs in the leaves of plants. Eating, thrips pierce plant tissue and suck out the juice. In places where they are formed point injections, merging with each other.

    Symptoms on the leaves and petals of roses from thrips appear discolored silver stripes and spots, often turning black around the edges. Kidneys from affected thrips roses bloom poorly, leaves are deformed and dry out, buds wither, blooming flowers lose their decorative effect. In Silene reproduction and distribution of thrips helps dry and hot weather.

    Measures to combat all the affected parts of the plants thrips removed and destroyed. Autumn around the bushes were collected and burned plant remains, dug up the soil. Rosalie sawflies (warty, ascending, grebenchatousy, descending, slimy) - relatively krupnyekrylatye insects, larvae and pupae that overwinter in the soil under the rose bushes. Symptoms: individual shoots roses droop, the leaves on the affected sawfly shoots wither, and die nadlamyvayutsya shoots.

    Spring sawflies lay eggs under the skin of the leaves or young shoots in veins or in the leaf axils. The eggs appear large whitish larvae (about 15 mm), which devour the flesh of the sheet penetrate escape and come on down (top-down) or up (ascending sawfly). Rosalie borers harm roses similarly sawflies laying eggs on the ends of the young shoots of roses. Hatched larvae penetrate into the flight, the damaged part of which perishes.

    Rosalie uzkotelye borers - beetles that appear on the roses in late spring. They eat away at the leaves of a small hole, hold the clutch of eggs on the bark of the shoots. Borers larvae penetrate the escape and move under the bark along the escape rose, gnawing at him intersecting passages. The presence of larvae borers inside shoots evidenced by their browning. Borers overwinter as pupae in the shoots.

    Control measures include the affected sawflies, borers and Zlatko shoots roses are pruned to healthy tissue and burn; it is desirable to do so prior to the release of pests pobegov.Obnaruzhennyh larvae destroy. The whole season periodically loosen the soil around the bushes. In the rose garden carefully collect the dry fallen leaves, cut off the dry parts of the shoots, burn crop residues roses and dug up the soil in the fall.

    Rosalie leafhoppers - quite clearly visible pests (up to 4 mm in length), providing laying eggs on the bark of the shoots. Adult leafhoppers and their larvae eat away the flesh and suck the juice from the leaves of roses. In central leafhoppers produce two generations - at the beginning and at the end of the summer. Wintering leafhoppers passes on the bark of the shoots of roses.

    Leafhoppers are often found on the roses growing in a dry and warm place. T his greenish-yellow insects usually sit on the underside of leaves along the veins, sucking the cell sap. When anxiety leafhoppers jump to the ground or fly. Symptoms: When you are in the rose garden of leafhoppers on the upper side of the leaves of roses there are white spots and flecks. Leaves wither and fall prematurely.

    Control measures at a mass invasion of leafhoppers leaves roses on all sides thoroughly sprayed with insecticide (eg, sodium kinmiksa - 2.5 g per 10 liters of water). Rosalie listovёrtki - small inconspicuous butterflies flying at dusk or at night. Listovёrtki overwinter in the bark of the trunk or branches of fruit trees. Symptoms: The individual leaves of roses wrapped into a tube and die.

    Butterflies - listovёrtki lay their eggs on the edges of the leaves. The eggs appear whitish or pale green caterpillar larvae; at the end of July they reach a length of approximately 9 mm. Leaf-caterpillars gnaw cavity in the kidney, eat up leaves and buds of roses; they entangle leaves cobwebs, turning them into a tube.

    Control measures in low lesion individual infected leaves and buds pluck out and destroy. In severe cases the plants are sprayed with pyrethrin-containing preparations (including the underside of leaves). Rose and thick-walled gall wasps - small (about 4 mm) winged insects that lay their eggs in the leaves and shoots of roses in May and June.

    Symptoms: in feeding hatched larvae are formed multi-chamber growths Gallen (5-50 mm in diameter) with dense long hairs, where the wintering larvae and pupation. Control measures include cutting and burning of the Gauls seen until the spring of them flew, new pests.

    Rosalie aphids sucking juices from the leaves, petioles, peduncles, buds, young shoots imozhet infect rose by more than 10 viruses; overwinters on the bark of the shoots of roses. Symptoms: buds, leaves, stems of roses tips in the presence of aphids on them deformed, shoots and flowers cease to grow due to lack of nutritious juices. Appearance and active reproduction of aphids helps dry weather, excess nitrogen fertilizer.

    Control measures should ensure that the plants in the rose garden fresh air, observe the dosage nitrogen-containing feed roses. Upon detection of a small number of aphids destroy her hands; aphids easily crush fingers.

    Strongly struck with aphids rose bushes can sprinkle soap solution (100-200 g of soap per 10 liters of water), nettle or other suitable preparation of plant defenders. On my roses all aphids collected numerous sparrows, which I fertilize in winter in the garden. Live birds under our roof; passerine families a lot.

    Bedbugs fields (field) and their larvae, as well as aphids, are vectors of viral diseases. They vysysyvayut juice from the leaves, buds and flowers of roses. Bugs lay eggs in the petioles and veins of leaves; overwinter in plant debris and weeds. Symptoms: leaves and shoot tips turn yellow and dry up roses, flowers and buds covered with spots and fall off. Control measures include cleaning the garden of weeds and plant residues; spraying drugs from plants defenders or insecticides with a large number of pests.

    Spider mites - microscopic and subtle to the naked eye, but very harmful arthropods that suck sap from the leaves and young shoots. Mites overwinter in the bark of the shoots and branches, garden plants, in the crevices of the greenhouses, in leaf litter, in the weeds.

    Symptoms: leaf surface affected by ticks roses covered with yellow speckles, which then becomes brown. On the underside of the affected leaves visible mites finest web within which mites lay eggs. Control measures include spider mites are actively developing in the dry and hot air at high temperature. Protect the predatory mites destroying spider mites. Treat the affected spider mites rose decoction of horsetail, sulfur-the tar emulsion and acaricide.

    Scale insects - moving in the stage of microscopic larvae, and with the growth and development of becoming fixed (as an adult) insects. The adult scale insects has reliable protection from external influences in the form of small waxy "flake-boards."

    Symptoms: scale insects firmly fixed on the leaves and shoots of roses, sucking the juice from them. The first sign of the emergence of scale insects - their shiny sticky discharge, similar to spray syrup. In these secretions settles sooty fungus that looks like a black plaque. Development of the affected plants schitovkami slows; with mass infection rose may die. Most often, scale insects appear on the loose roses growing with insufficient care for very dry or wet areas.

    Control measures should carefully choose the place for planting roses and protect the natural enemies of scale insects. Detected on individual scale insects rose brushes brush, swab or soapy cloth. Accumulations of pests sprinkle with paraffin or mineral oil, which covers the scale insects film, so that pests becomes hard to breathe. Last resort to combat scale insects - the use of insecticides.

    Leaf-cutting bees that feed on the nectar of flowers, cut along the edges of the leaves of roses small right semicircles, thus causing no significant harm to plants. Recommended weeding in the garden sow-thistle, thistle and other Compositae weeds in the stems that leaf-cutting bee suits home.

    The greatest harm flowering roses causes bud midge, caterpillars that eat the tops of the shoots, ie flower buds in the bud. Of the pest I've never seen, only traces of it - the web. If caterpillars midge do not fight, instead of beautiful flowering rose bushes only get greens, as the caterpillars eat all the flowers in the bud. But this is not always the pest affects roses, mostly - in a hot April and May.

    In early May, I will first spray the roses from leaf-eating beetles and caterpillars in cloudy or windless weather in the evening (polyethylene film protecting growing near fruit plants and soil). During the season I spend processing roses from pests as needed.
