- Scale Insects Scale insects are a peculiar group and look quite different from the typical insects we encounter day to day. Small, immobile, with no visible legs or antennae, they resemble individual fish scales pressed tightly against the plant on which they are feeding. There are over l50 different kinds of scales in Virginia. Many are common and serious pests of trees, shrubs, and indoor plants.
- Fall Webworm Native to North America, the fall webworm occurs throughout the United States and southern Canada. Its hosts include more than 100 species of deciduous forest, shade, and fruit trees, with preferences varying from region to region.

- Fusarium Wilt of Mimosa (Albizia julibrissin) Fusarium wilt is a common and lethal disease of mimosa (Albizia julibrissin)1, also commonly known as silktree. In the United States this disease occurs in the east from New York southward and also in Louisiana, Arkansas and California. Fusarium wilt is caused by the fungus Fusarium oxysporum forma specialis perniciosum. Albizia spp. are the only known host of F. oxysporum'' f.sp. ''perniciosum''. Fusarium oxysporum f. sp. perniciosum colonizes and clogs the tree’s vascular (water-conducting) tissue, and interferes with the movement of plant sap. This results in relatively rapid tree death.
- Spongy Moth Management for Homeowners "Spongy moth (Lymantria dispar; formerly called gypsy moth), is an invasive pest of hardwood trees in forests and yards. The caterpillars prefer the foliage of oak and other shade trees, but also attack conifers. Spongy moth caterpillars can defoliate large trees during outbreaks, and most homeowners object to the numerous hairy caterpillars and their abundant droppings raining out of infested trees. Since its introduction to Massachusetts in 1869, spongy moth has spread throughout the northeastern US, down in the mid-Atlantic, around the Great Lakes, and into Canada. Most of Virginia is generally infested with spongy moth, but it may not cause widespread defoliation every year."
- American Beautyberry (Callicarpa americana) The primary and sole attribute of beautyberry, a large loosely branched shrub, is the showy display of magenta fruits in the fall.

- Growing Pears in Virginia Pears are the second most important deciduous tree fruit after apple, and it has been grown in Europe since prehistoric times. Pears belong to the genus Pyrus and probably originated near the Black and Caspian Seas. French and English colonists brought pears to America and the first record of pears in the North America was in Massachusetts in 1630. Although pear is a popular fruit, it is not grown as widely as apple. Pears can be grown throughout much of North America because they tolerate a wide range of climatic conditions.
- Growing Cherries in Virginia Cherries are grown in many parts of the world, but they have never gained the popularity in North America that they have in Europe and the Middle East. Cherries probably originated in the region between the Caspian and Black Seas, where trees still grow in the wild.
- Growing Peaches and Nectarines in Virginia An orchard is a long-term investment and careful planning is essential to ensure economic success. Establishing and maintaining a peach planting to bearing age (three years) costs about $3,500 per acre. Mistakes made at planting often cannot be corrected; other mistakes that can be corrected could seriously jeopardize the economic success of the orchard. Because profit margins for commercial fruit plantings are small, orchards should be established only under the most favorable conditions for success.
- Pruning Peach Trees Annual pruning is a critical management practice for producing easily harvested, heavy crops of high quality peaches. However, pruning is not a substitute for other orchard practices such as fertilization, irrigation, and pest control. Pruning practices vary slightly in different regions of the United States, but have changed little in the East during the past 70 years. Although pruning may vary slightly for different varieties and localities, certain general practices should be followed. The successful pruner must understand the principles of plant growth, the natural growth habit of the tree, and how the tree will respond to certain types of pruning cuts. Improper pruning will reduce yield and fruit quality.
