PPFS-OR-W-28: Laurel Wilt Disease and Redbay Ambrosia Beetle

Ellen Crocker, Tyler Dreaden, Nicole Gauthier, Jonathan Larson, Kimberly Leonberger | July 8, 2020 (New)

Laurel wilt is a newly discovered fungal disease that presents a major threat to sassafras in Kentucky. The disease was first detected in the U.S. in 2003 and in southwestern Kentucky in 2019. Currently, laurel wilt is known to occur in eleven southeastern states bordered by Kentucky (north), North Carolina (east), Florida (south), and Texas (west). Research is ongoing to determine the impact and distribution of both the laurel wilt fungus and the redbay ambrosia beetle that carries it.

ID-260: An IPM Scouting Guide for Common Problems of Peach in Kentucky

Ric Bessin, Nicole Gauthier, Cheryl Kaiser, Matthew Springer, John Strang, Shawn Wright | June 8, 2020 (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 peach plantings.

PPFS-FR-S-30: Cultural Calendar for Commercial Strawberry Production

Ric Bessin, Nicole Gauthier, Kimberly Leonberger, Matthew Springer, John Strang, Shawn Wright | May 27, 2020 (New)

Inegrated pest management (IPM) includes the combination of biological, cultural, physical, and chemical tools in efforts to manage diseases and pests while minimizing risks associated with pesticides. Cultural practices are an integral part of an IPM program and should be incorporated into all commercial systems whether large or small, conventional or organic. This publication provides recommended practices at approximate growth stages and/or production periods. However, these timelines are approximate and may require adjustment for particular conditions. Growers who encounter situations that may not align with suggestions here should contact their county Extension office for assistance.

FOR-137: Hardwood Growth Rings

Terry Conners | January 10, 2020 (New)

As in softwoods, hardwood species identification is accomplished by looking at species-specific combinations of features. Almost all hardwood species (including all of those from North America) contain vessels which appear as holes (pores) on wood cross-sections; hardwood species without vessels are unlikely to be encountered in North America. Those species are more commonly found in the southern hemisphere and are rarely sold as commercial species.

FOR-135: Softwood Growth Rings

Terry Conners | January 10, 2020 (New)

Many softwoods look similar to the naked eye at first; the colors are often similar, maybe light-colored overlaid with tinges of yellow-brown or perhaps a slight pinkish cast. Even the weights of similarly-sized pieces (the densities) might seem similar. There are, however, differences in the wood structure that we can use to separate the various species. Two of the most important characteristics we look at are 1) the presence or absence of resin canals (as discussed previously) and 2) the appearance of the earlywood--latewood transition in annual growth rings.

FOR-138: Wood Structure and Mechanical Performance are Related

Terry Conners | January 10, 2020 (New)

There is a strong correlation between wood density and mechanical properties, and this is true for both softwood and hardwood species. Density and strength properties can vary even within species due to different growth conditions.

FOR-136: Further Distinguishing Softwood Species

Terry Conners | January 10, 2020 (New)

Recognizing that an unidentified sample is a resinous or non-resinous softwood, with either an abrupt or a gradual transition is a good start towards identifying an unknown specimen. The problem is that this information is rarely enough! Other characteristics need to be combined with that data. Some of the things to look out for include characteristic odors, the diameter of the tracheids, and the presence of storage cells. Sometimes the context or original location of the material can be helpful.
