ID-254: An IPM Scouting Guide for Common Problems of Grape in Kentucky

Ric Bessin, Cheryl Kaiser, Matthew Springer, John Strang, Nicole Gauthier, Patsy Wilson, Shawn Wright | Jun. 11, 2019 (New)

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky grape plantings.

CCD-CP-80: Hops

Matthew Ernst, Cheryl Kaiser | May. 3, 2019 (Minor Revision)

Hop (Humulus lupulus) is a native herbaceous plant with a perennial crown and annual climbing stems (bines). Bines are similar to vines; however, bines wind around a support structure and lack the suckers or tendrils typical of vines. Hop crowns can survive for 25 years or more; however, the fast growing bines die back to the ground each winter. Bines can reach a height of 15 to 30 feet in a single growing season. Hops are valued for their female cones, which contain the resins and essential oils used to provide the distinctive flavor, aroma and bitterness to beer.

CCD-CP-77: Bamboo

Matthew Ernst, Cheryl Kaiser | Apr. 9, 2019 (Minor Revision)

Bamboo is the general name used for a number of perennial, woody-stemmed grasses. Native cane (Arundinaria gigantea), which is commonly referred to as river cane, grows naturally in Kentucky and throughout much of the Southeast. It is one of three bamboo species native to North America. There are more than a hundred introduced species that can be grown in the U.S., with growth habits ranging from low-growing groundcovers to full-sized trees that reach a height of over 30 feet at maturity. Bamboos are well known for their vigorous growth and variety of uses.

PPFS-VG-21: Sustainable Disease Management of Solanaceous Crops in the Home Garden

Kimberly Leonberger, Emily Pfeufer | Apr. 1, 2019 (Minor Revision)

Solanaceous crops, including tomatoes, peppers, eggplants, and potatoes, may be the most popular garden plants, but many diseases commonly affect them. Early blight and Septoria leaf spot occur each year under even the best disease management, and bacterial spot may be spread easily under rainy conditions. A combination of approaches, such as using resistant varieties, record-keeping, cultural, and chemical management, is the best practice for minimizing vegetable garden diseases.

PPFS-GEN-7: Homeowner's Guide to Fungicides

Kenny Seebold, Nicole Gauthier | Apr. 1, 2019 (Minor Revision)

Diseases in home gardens, orchards, and landscapes do not always cause total losses, but they can be serious problems if left unmanaged. As a rule, chemicals are not recommended as the only means of disease control for homeowners. Cultural practices such as sanitation, irrigation management, attention to plant health, rotation, and selection of disease-resistant varieties are usually enough to control diseases. Chemicals may be required, though, and should be used as a supplement to good management practices.
