Information about the natural habitat in which a particular native is found may be used as a guide to determine what native plants can be used in particular landscape situations. Armored scales are relatively waterproof; they live under a waxy cover. The life-stage most susceptible to insecticides is the crawler stage, which typically appears in spring. The insect is native to Asia. Cupressus nootkatensis aka Chamaecyparis nootkatensis (Nootka false cypress, Zones 4-7(8)) is a conical specimen with numerous drooping branches with long flattened leaves which are dark bluish green or grayish green.

Follow Lubell on Facebook at Native Plant Gal for help with native shrub propagation and production, as well as landscape use. A three-pronged approach is recommended, so that all life stages of tea scale may be addressed. Japanese barberry (Berberis thunbergii) and winged euonymus (Euonymous alatus) were also planted as controls to understand how the natives perform compared to these tough, old landscaping standbys. Within a site, crawler emergence is fairly synchronized and lasts two to three weeks. ‘Nana’ is an extremely slow growing cultivar to about 3 feet high and slightly broader with dark green foliage. Emerging technologies can also be used to remotely monitor real-time soil moisture levels, as well as provide weather, soil temperature, flow meter and other sensor-based data. Armored scale parasites include species of tiny Aphytis and Aspidiotiphagus (family Aphelinidae), ... (REI) is the number of hours (unless otherwise noted) from treatment until the treated area can be safely entered without protective clothing. Have light bulbs and fixtures been cleaned recently?

The next step in efficient irrigation is regular maintenance and audits of your irrigation system. A.G. Dale, NCSU. This can reduce plant growth and vigor. Scale has several different “pupa” stages referred to as nymphs or instars. Scales, especially armored scales, are difficult to control. Deciding if management is necessary—an important IPM concept—is not well-established for scale insects or any landscape pests. Performing irrigation audits is more time intensive. The benefits of sensor-based irrigation management are similar to compound interest with your savings account: good decisions made on a frequent basis are likely to lead to multiple benefits, because the plant has optimal growing conditions for an extended period of time. Horticultural oils can also be effective for armored scale management. One of the most stubborn examples of an armored scale is the San Jose scale, Quadraspidiotus perniciosus. Water-use efficiency begins with irrigation design. These yellowish lights are also suitable for indoor areas where color rendition is not important. Used in Mystic Forge. So, learn ways on how to treat hard or armored scale. Drip or spray stakes are recommended for size #5 or #7 containers or greater, as these larger containers typically cover only 9-35 percent of the production area. Sweet gale (Myrica gale) Crawlers are the only mobile stage of armored scales and the only stage without a test. Sarah White is assistant professor, Nursery Extension Specialist at Clemson University. There are also cultivars in my selection deserving of a larger audience. Sweet gale will tolerate light shade and infertile soils, the latter due to its nitrogen fixing ability. Are water faucets dripping? Imidacloprid controls European elm scale and most soft scales but does not control cottony cushion scale and most armored scales.
