What To Put On Rose Bushes To Keep Bugs Off
With their showy and ofttimes fragrant blooms, roses are hands 1 of the most popular flowering plants grown in S Carolina. Unfortunately, the numerous insects and related pests that assail them can make growing them "interesting", if not outright challenging. As with whatsoever found, the priority should be to provide the rose with the cultural conditions required for best wellness. A vigorously growing rose is much more likely to survive pest damage than a stressed constitute. For more than data on the cultural requirements of roses, see HGIC 1172, Growing Roses and HGIC 1173, Pruning Roses. For information on diseases of roses, see HGIC 2106, Rose Diseases.
When trying to control insects and related pests on roses, the plants must be thoroughly inspected regularly. These inspections increase the likelihood that a pest infestation volition be detected early on, when pest numbers are low and control is easiest. For the best command methods, information technology is first necessary to place the pest correctly. Frequently, more than one control option is available for a pest. Whenever possible, initially try physical control measures. If chemical control is necessary, use the least toxic chemical, plus exist sure to apply information technology at the about susceptible stage of the insect pest. When applying a pesticide, thorough spray coverage of the plant is of import. Always be sure to read the pesticide characterization before purchasing. Apply all pesticides according to characterization instructions, and follow all precautions.
Aphids

Anne W. Gideon, www.insectimages.org
Various species of aphids feed on roses, but the predominant species is the rose aphid (Macrosiphum rosae). Rose aphids are small (well-nigh ⅛ inch long). They are soft-bodied, pear-shaped, pink or green insects found in clusters on new growth of buds, leaves, and stems.
Aphids feed on plant sap with their piercing-sucking mouthparts. A low population of aphids does little damage to a rose bush; yet, aphids reproduce rapidly and tin speedily achieve numbers that crusade damage. Their feeding results in distorted growth. Heavy infestations tin reduce the number and quality of blooms. As they feed, aphids excrete honeydew, a sugary substance that attracts ants and wasps. The honeydew supports the growth of unsightly, nighttime-colored sooty mold fungi on the leaves.
Control: Aphids have several natural enemies, including parasitic wasps, ladybird beetles (ladybugs) and larvae, and green lacewing adults and larvae. Their natural enemies tend to keep aphid populations under control except in cool weather. Ants are sometimes associated with aphid infestations, and they will protect the aphids from their natural enemies. If ants are present, they should be controlled.
Aphids can exist hosed off with a strong stream of water directed above and below the leaves. Spraying with water should be repeated as oft equally needed, focusing in particular on new growth. Roses can also be sprayed with insecticidal soap to control aphids. Insecticidal soap must be sprayed onto the aphids to be constructive. Repeat the insecticidal soap spray three times at 5 to 7-twenty-four hours intervals. Higher toxicity insecticides are available. However, it is important to note that aphids are very hard to control because they multiply rapidly. Leaving even ane aphid alive can consequence in a large population very apace. In addition, these insecticides kill the natural enemies of rose aphids.
If contact insecticides are accounted necessary, the following are available in homeowner size packaging. Sprays containing bifenthrin, cyfluthrin, horticultural oil, lambda cyhalothrin, malathion, neem oil, permethrin, or pyrethrin volition control aphids. Soil drenches or granular applications of systemic insecticides, such as imidacloprid or dinotefuran, will control aphids and last longer within the plant to prevent future infestations. See Table 1 for products containing these insecticides.
Beetles
Japanese beetles (Popillia japonica) with characteristic damage of leaf skeletonization.
David Cappaert, Michigan State Academy, world wide web.insectimages.org
A number of different protrude species feed on roses. Many of these beetles feed mainly on flower buds or open blossoms merely can feed on leaves. Since many beetles feed mainly at night, the gardener rarely sees them, only the impairment that they crusade.
Japanese beetles (Popillia japonica) feed during the day and are perhaps the most readily recognized beetle pests that feed on roses. An developed Japanese beetle is about ½ inch long and has a metallic green body and legs with coppery-brown wing covers. It can be distinguished from like beetles by the tufts of white pilus visible at the end of its abdomen.
The adults begin emerging from the soil in mid-May and are present through August. They tin live from thirty to 45 days. They lay their eggs in the soil. Grubs hatch from the eggs and feed on grass roots. Every bit the conditions cools, the grubs move more deeply into the soil to overwinter (survive the winter). In the spring, the grubs migrate back up to the root zone and continue to feed. They pupate (alter to developed form) in late Apr and May.
Japanese beetles have chewing mouthparts and feed on flowers, buds, and leaves of roses (as well as numerous other constitute species). Partial or entire flowers and buds may be eaten. Typically, flowers and buds that have been fed on take ragged edges and/or holes in the petals. Affected buds may fail to open. Rose leaves are typically skeletonized (but foliage veins remain) by the feeding. Leaves with tender veins may be eaten completely.
Command: Diverse non-chemical command options are available for Japanese beetles. They can exist handpicked and destroyed by dropping them into soapy water. When only a few plants are involved, fine netting, such as tulle material, or spunbound polyester material, such as Reemay, can exist placed over the bush or private blossoms to exclude the beetles. Japanese beetle traps are available commercially but should exist used with caution. They tin effectively reduce adult populations, but they should be kept at least 50 feet from the institute(s) existence protected. The traps have the potential to create more of a problem by alluring numerous beetles into the landscape Additionally, traps must be emptied often equally beetles are repelled past the odour of ammonia, which is released by dead, rotting beetles.
The number of adults may also exist reduced by using the product Milky Spore against the grubs in the lawn. This product contains a disease-causing bacterium (Paenibacillus popilliae) that specifically infects the grubs of Japanese beetles. It is applied to the entire backyard, and once established, tin be effective for 20 to 30 years. Withal, every bit the adults are strong fliers, they can fly in from nearby lawns and pastures.
It is important to continue in mind that rose blossoms openly speedily and are very attractive to Japanese beetles. These circumstances make information technology challenging to keep the blooms adequately covered with insecticide to protect them. Insecticides labeled for homeowner utilise include sprays containing bifenthrin, cyfluthrin, lambda cyhalothrin, neem oil, permethrin, or pyrethrin to control beetles. Soil drenches or granular applications of imidacloprid or dinotefuran will control Japanese and other beetles and last longer within the constitute to prevent future infestations. Encounter Table i for specific products.
Mites
Mites are non insects but are more closely related to spiders with viii legs as adults instead of 6. They are extremely pocket-sized (almost one/fifty-inch long) and are somewhat difficult to run across without a magnifying lens. One way to detect them is to agree a slice of white paper nether a branch and so tap the branch sharply. Wipe your hand over the paper. If mites are present, reddish streaks volition exist seen.
Two-spotted spider mites (Tetranychus urticae) and southern carmine mites (Oligonychus ilicis) are pests on roses in Due south Carolina. Two-spotted spider mites are more of a problem during hot, dry weather condition, and susceptibility increases when a rose is drought-stressed. Southern ruddy mites are more of a problem during cool weather in leap and fall, and their populations drop during summer.
Spider mite (Tetranychus urticae) webbing and plant injury.
Clemson University – USDA Cooperative Extension Slide Series
Mites accept piercing-sucking mouthparts. They suck establish sap, typically feeding on the lower surface of a foliage. Early damage is seen as yellow or white speckling on the upper surface of leaves. Fine webbing may exist seen on the undersides of leaves. With severe infestations, leaves may develop a grayish-greenish or statuary color, and webbing may cover both sides of leaves and branches. Severely infested leaves may driblet prematurely. In addition, the webbing can collect grit, making the establish look dingy.
Control: Beneficial insects, such as lacewings, lady beetles, and predatory mites, casualty on spider mites. Predatory mites are well-nigh the aforementioned size equally spider mites but can be distinguished from spider mites by their long legs and the speed with which they motion. Several species of predator mites are available commercially for use every bit biological command agents.
A stiff spray of water is a non-chemical control option that removes eggs, larvae (six-legged immature stage), nymphs (eight-legged young mites), and developed mites. Exist certain to spray lower surfaces of leaves and echo as needed. This method is most effective with light infestations, every bit seen with early detection. An important advantage of this control method is that populations of natural enemies are not harmed.
Insecticidal soaps and horticultural oils are effective control options for spider mites, and they are essentially nontoxic to humans, wildlife, and pets, and but minimally toxic to beneficial predators. Adept coverage is critical to ensure contact with the pest when using these products, and reapplication may be needed as determined past follow-up monitoring for the pest. Foliar injury from soaps and oils may occur on plants under drought stress. H2o the plants well before spraying. Practise non spray with soaps or oils if the temperature exceeds 85 °F, and ever spray in the evening to slow the drying time of the soap or oil. Sulfur sprays can too command spider mites. Exercise not spray if the daily temperatures will exceed 85 °F, and do not spray sulfur on plants within 30 days of a horticultural oil spray.
When growing roses, the use of broad-spectrum insecticides should be avoided as much as possible, equally these products can kill off natural enemies that assist proceed spider mite populations in check. Likewise, avoid pesticides that merits to "suppress" mites equally they tend to be weak miticides. When stronger chemical control is needed, the following insecticides/miticides are available in homeowner size packaging: tau-fluvalinate or bifenthrin sprays. Meet Tabular array i for examples of brands and products.
Thrips
Various thrips species feed on roses. Two of the most common are flower thrips (Frankliniella tritici) and western blossom thrips (F. occidentalis).
Thrips (Frankliniella sp.) damage on roses.
Clemson University
Woman thrips of both species are tiny, yellowish-brown insects with fringed or feathery wings. At less than i/16-inch long, they are barely visible without a magnifying glass. However, blowing lightly into the blooms and leaves causes thrips to motion around, making them easier to meet.
Both young and adult thrips feed by scraping surface cells to suck institute sap. They feed on both leaves and flower petals, with the majority of their damage to roses occurring from early on to midsummer. Their feeding may issue in distorted buds that open only partially or abort prematurely. Feeding on petals may result in petals streaked with silvery-white or brown equally well every bit petals with browning edges. White and light-colored rose blossoms announced to be particularly attractive to thrips. Young leaves become distorted and flecked with yellow post-obit extensive thrips feeding.
Control: Control of thrips is hard. Infested rose blossoms should exist removed and destroyed. Grass and weeds in the area should exist kept mowed or removed when possible. Insecticides are available, but the timing of sprays is very important. They must be applied before thrips enter unopened buds. In add-on, because rose blooms expand speedily, it is challenging to keep them adequately covered with insecticide. If it becomes essential to spray an insecticide, the post-obit are available in homeowner size packaging: acephate, spinosad, bifenthrin, cyfluthrin, lambda cyhalothrin, or permethrin. Withal, both acephate and spinosad are foliar systemic insecticides and are capable of penetrating closed flower buds to impale thrips within. Insecticidal soaps will assistance control thrips, but thorough coverage is necessary. The lather spray must contact the pest to exist effective and may crave 3 sprays at 5- to seven-twenty-four hours intervals. Soil drenches or granular applications of dinotefuran or imidacloprid will give thrips suppression. See Table 1 for examples of brands and products.
Rose Calibration
Adult rose scale (Aulacaspis rosae) on a rose cane.
U.S. National Collection of Scale Insects Photographs Annal, USDA ARS, www.insectimages.org
Adult calibration insects have an unusual appearance. They are more often than not pocket-sized and immobile, with no visible legs. They secrete a waxy covering, making some appear white and cottony, while others appear similar white, yellow, brown, or black crusty bumps. The waxy covering or "scale" protects adult scale insects from many insecticides. Their immature forms, called crawlers, are susceptible, however.
Several species of scale are pests of roses, but rose calibration (Aulacaspis rosae) is one of the nearly serious. Female rose scales are round, greyness to white, and about ane/16-inch long. Males are elongate, white, and much smaller than females. These insects overwinter as eggs under the waxy roofing of the female parent.
Rose scales are usually found on rose canes, where they feed on sap with their piercing-sucking mouthparts. With a heavy infestation, rose calibration tin can cause pikestaff turn down or twig dieback.
Command: Various natural enemies, including ladybird beetles (ladybugs) and parasitic wasps, usually keep scale insects nether control. With calorie-free infestations, scrape off and destroy scales past hand. Pruning out and destroying heavily infested canes is helpful. Horticultural oil sprays (too called supreme, superior, or summer oils) work well to control armored scales, such as the rose calibration, by penetrating their waxy covers and smothering them. Horticultural oils practical at higher rates of 3% to 4% during the fallow season (i.east., to a rose bush-league that has lost its leaves) will penetrate the thick waxy covers of the overwintering adults. Applications at lower rates of 1% to two% can be sprayed during the spring to target the crawlers (immatures) and the newly settled scales with thin waxy covers. Information technology is best to spray when temperatures are betwixt twoscore and 85 °F.
Monitor the crawler emergence in the spring with sticky cards, double-faced record wrapped around a co-operative, or past putting an infested shoot into a baggie and watching for crawler movement. The presence of crawlers can sometimes be determined by sharply borer an infested twig on a slice of white paper. Crawlers are very small and appear equally moving specks of dust.
Avoid using insecticides as much every bit possible, as they will often kill the naturally occurring enemies of scale. When insecticides are necessary during the growing season, they should exist applied when the crawler phase is present. The following insecticidal sprays are effective against crawlers only: acephate, bifenthrin, cyfluthrin, lambda cyhalothrin, malathion, or permethrin. Soil drenches of imidacloprid do non command these armored scales, only soil applications of dinotefuran will give practiced control.
Rose Leafhopper
Adult rose leafhoppers (Edwardsiana rosae) vary in color from white to gray to xanthous to dark-green. They are wedge-shaped and between ¼- to ½-inch long. When a constitute is disturbed, they hop or fly away quickly.
The adult female person deposits eggs within the bark of rose canes in the fall. Dark, purple, pimple-like spots on the bark point the presence of eggs. In the spring, the young nymphs (young forms that resemble adults merely are wingless) emerge from the cane. The wounds that remain in the bawl as they emerge, too equally wounds made during egg-laying, tin provide openings for stem canker-causing fungal pathogens to enter. Stalk canker can consequence in plant expiry.
Nymphs and adult leafhoppers feed on the undersides of leaves, using their piercing-sucking mouthparts to suck plant sap. Their feeding causes white stippling (small dots) on the upper surface of the leafage. The stippling spots may merge, causing leaves to appear almost white. Damaged leaves may drop prematurely. Between feeding past the nymphs and adults, and egg laying by adult females, a severely infested rose bush-league may be killed.
Control: Natural enemies of rose leafhoppers include damsel bugs and assassin bugs. Broad spectrum, contact insecticides should be avoided, every bit they may kill these beneficial predators, too. However, when an insecticide is necessary, be sure to spray lower leafage surfaces thoroughly. The following insecticidal sprays are effective confronting rose leafhoppers: acephate, bifenthrin, cyfluthrin, lambda cyhalothrin, malathion, or permethrin. Soil drenches or granular applications of dinotefuran or imidacloprid will suppress leafhopper populations. See Table 1 for specific products.
Rose Slugs

John A. Weidhass, Virginia Tech, world wide web.insectimages.org
Rose slugs are the larvae (immature forms) of sawflies, not-stinging members of the wasp family. Three species of sawflies, the rose slug (Endelomyia aethiops), bristly rose slug (Cladius difformis), and curled rose sawfly (Allantus cinctus), are pests of roses. The larvae of some sawfly species are hairy and often mistaken for caterpillars. Others announced wet and shiny, superficially resembling slugs. The larvae generally reach most ½- to ¾-inch in length.
Generally, rose slugs feed at night. Depending on the species, immature rose slugs feed on the upper or lower surfaces of leaves betwixt veins, leaving a 'window' of translucent tissue that turns brownish. As some species of rose slugs get larger, they chew large holes or the entire leaf with but the midrib remaining. Regular inspection of roses is important because feeding typically progresses quickly, and extensive foliage skeletonizing can occur if infestations are not noticed. In addition, with their coloring, they can be very difficult to spot on leaves.
Control: Rose slugs can exist controlled past handpicking. They tin also be removed by spraying with water. Once dislodged, they cannot climb back onto the plant. Insecticidal soap and horticultural oil are also constructive confronting rose slugs. Other insecticidal sprays that are labeled for homeowner use include acephate, bifenthrin, cyfluthrin, lambda cyhalothrin, permethrin, or spinosad. Sprays should thoroughly cover both upper and lower leafage surfaces. Soil drenches or granular applications of dinotefuran or imidacloprid will control sawfly larvae.Bacillus thuringiensis (Bt) will merely control true caterpillars and not the larvae of sawflies. Encounter Table ane for examples of brands and products.
Leafcutting Bees

Whitney Cranshaw, Colorado State University, www.insectimages.org
Leafcutting bees (Megachile species) are like in size to honeybees only are blackish, metallic purple, or green. The females cut out semi-circular sections of leaves, which they use to line their nests. The cut surface is very smooth as compared to the ragged edge that results with most foliage-feeding insects.
Control: No control is recommended because the harm acquired by leafcutting bees is minimal, and the bees are important every bit pollinators.
Caterpillars
Infrequently caterpillars (young phase of moths and butterflies) will be plant feeding on rose foliage. Feeding damage appears as holes or irregular-shaped areas of the leaf blades. Several caterpillars may feed upon rose foliage, including the corn earworm, eastern tent caterpillar, stinging rose caterpillar, and puss caterpillar.
Command: Insecticidal sprays ofBacillus thuringiensis, acephate, bifenthrin, cyfluthrin, lambda cyhalothrin, malathion, neem oil, permethrin, pyrethrin, or spinosad volition control caterpillars. See Table 1 for examples of brands and products.
Grasshoppers
Grasshoppers are general feeders that feed on the leafage of many kinds of plants.
Control: Keep weeds and grass most roses under control because these are the breeding sites for grasshoppers. Insecticidal sprays with acephate, bifenthrin, cyfluthrin, lambda cyhalothrin, malathion, permethrin, or pyrethrin will control grasshoppers. See Tabular array 1 for examples of brands and products.
