Several foliar sprays applied in 7 to 10 day intervals, or as directed on the products label, may be necessary to provide protection of new foliage through the period of egg hatch, particularly when using insecticide products with little or no residual activity such as insecticidal soap or horticultural oil.

University of Maryland Extension, Scale Management Guidelines. Honeydew drippings from plants can be efficiently monitored using water-sensitive paper, which is commonly used for monitoring insecticide droplets and calibrating sprayers. Unlike other insects, they are immobile once they lock themselves into place to pierce the plant and begin feeding on sap. This is likely the case with barnacle scales, too. Outdoors beneficials, like lady bugs, can help by devouring the scale pests. For assistance with a specific problem, contact your local Cooperative Extension Center. Pest Notes: Black Scale.

Wash dust off of ficus tree foliage with a strong spray of water whenever a large amount of dust accumulates on the ficus leaves during the growing season, as dust disrupts natural predator activity. Pruning infected branches is often the easiest and surest solution if you catch the infestation while it is still light. Inspect the plant thoroughly, as well as any adjacent plants, to ensure you have removed all infested stems. NC State Extension Plant Pathology Factsheets, NC State Horticultural Science Publications, North Carolina Agricultural Chemicals Manual.

Florida wax scales have been reported infesting a wide range of host plants, including shrubs, trees and several herbaceous plant species. However, conserving resident natural enemies is a more efficient and longer lasting strategy than buying and releasing beneficials in gardens and landscapes. The female wasp lays one or several eggs in or on each scale, where the tiny maggotlike wasp larvae feed. Soft Scale Insects, Cottony Cushion Scale and Gumtree Scale all produce honeydew, which is a liquid of concentrated plant sugars they excrete. Thorough spray coverage is especially critical when treating armored scales and oak pit scales as these scales are generally less susceptible to pesticides than soft scales. Effective, slow-acting bait insecticides work over a period of days so that before ants die they will spread the toxicant among many other ants during food sharing. Armored scales, family Diaspididae, have a flattened, platelike cover that is less than 1/8 inch in diameter. Promote plant vigor and health by properly selecting preparing planting sites, and providing optimal watering and fertilization. Nymphs pass through a couple of moults before becoming adults.

Certain plants may be sensitive to oil-based sprays, so do a test spray on a small inconspicuous area and observe over the next couple of days to see if there is a reaction. Horticultural oil is effective in spring or summer on deciduous plants when sprayed soon after most crawlers have emerged and most scales are in the young nymph stage. Wax Scale nymphs resemble smaller versions of adult females. Scale insects typically adhere to the stems, branches, and sometimes the leaves of plants to feed on sap, and they have a shell-like bump appearance, which sometimes causes them to be mistaken for a fungal or bacterial disease. Avoid applying sticky material to horizontal surfaces where birds may roost. Third instar nymphs move to twigs where they mature into females and lay eggs beneath their body. Oakland: Univ. Apart from biological control (seeNatural Enemies), the mainstay of Scale Insect control is the application of horticultural oils. First generation scales settle on leaves, but Tape traps for crawlers and honeydew monitoring are useful in certain situations for determining the need and best timing for pesticide application. The alcohol alone should kill the scale, but the dead insects will remain on your plants and make it difficult for you to scout for new infestations. She's also an author of three gardening books, a plant photographer, public speaker, and a former Cornell Cooperative Extension Horticulture Educator. Identification of E. scitula. Rubbing alcohol can kill scale insects if the infestations are light. Most horticultural oils are some kind of petroleum-based mineral oil although there are some vegetable oils that also fight pests such as cottonseed oil and soybean oil. They then settle down to feed either on leaves, twigs or small branches. Scales attached to branches or twigs may be unaffected. B. and M. L. Williams. Nondiscrimination Statement.

Orange crawlers hatch from the eggs and disperse over the tree. Soft scales and certain other types feed on phloem sap and excrete abundant, sticky honeydew, which drips on plants and surfaces underneath and promotes the growth of blackish sooty mold.

On holly, Florida wax scales are easily spotted because most of them colonize the upper leaf surface. The eggs hatch into crawlers that initially settle along the mid-veins on the underside of leaves, but older nymphs migrate to twigs and branches where they remain. Crawlers walk over the plant surface, are moved to other plants by wind, or are inadvertently transported by people or birds. Provide plants with good growing conditions and proper cultural care, especially appropriate irrigation, so they are more resistant to scale damage. Pruning infected branches is often the easiest and surest solution if you catch the infestation while it is still light. After settling, nymphs insert their thread-like mouthparts into the plant and begin to secrete wax in tufts around the body that give them a star-like appearance.

At this point, the nymphs have legs and are actively crawling to find new spots to attach and feed. Regularly monitoring honeydew beneath plants, such as the number of drops during four hours on the same time of day once a week, can help to develop thresholds and evaluate effectiveness of the treatment. 4). A well-timed and thorough spray of horticultural (narrow-range) oil during the dormant season, or soon after scale crawlers are active in late winter to early summer, can provide good control of most species of scale. WebHeavy infestations of pine needle scale detract from the appearance and reduce the value of trees. For example, rinse small plants when foliage becomes dusty.
