A New Resource to Help Manage Pests on Nursery Crops and Landscape Plantings

Nursery/greenhouse growers and landscape professionals have a new tool that they can download to help manage pests and diseases. The Southern Nursery IPM Group (SNIPM) just released the  2017 Southeastern US Pest Control Guide for Nursery Crops and Landscape Plantings.  This new resource contains information about products used to control diseases and pests on nursery crops and landscape plantings. The intent is that the information be used as a guide to pest control decision-making and not a substitute for other aspects of IPM (Integrated Pest Management). The Guide was developed by Joe Neal (North Carolina State University), J.C. Chong (Clemson University) and Jean Williams-Woodward (University of Georgia) with contributions from many other university faculty, including Gary Knox and Chris Marble from the University of Florida. The Guide is available for download at the  NC State webpage , and check out additional IPM resources on the  SNIPM website.  
Nematode Assay Sampling

The Florida Nematode Assay lab is a facility in the State of Florida diagnosing samples for nematode assay. The lab determines the types and numbers of plant-parasitic nematodes in soil and plant samples.

Nematodes are a diverse group of worm-like animals. They are found in virtually every environment that can support life, and are found in fresh water, in salt water, in all kinds of soil, and as internal parasites of humans and animals. Most of the nematodes that inhabit the soil are microbial feeders or predators of other soil organisms, but some parasitize plants and are called plant-parasitic nematodes.

Plant-parasitic nematodes are important because they inhibit root growth and eventually overall plant development. Because plant-parasitic nematodes are difficult or impossible to see in the field, and their symptoms are often non-specific, the damage they cause is often attributed to other, more visible causes. The amount of damage nematodes cause depends on a wide range of factors, such as their population density, the virulence of the species, or strain, and the resistance or tolerance of the host plant, etc. The identification of plant- parasitic nematodes is necessary to confirm their presence. A nematode assay is a microscopic examination of soil and roots that identifies the identity of the given nematode and estimates population size and assesses the potential damage of any plant-parasitic species present. This is important to help in the development and evaluation of efficient nematode control strategies.

Dr. Billy Crow has developed two new videos about sampling for the nematode assay. He is sampling on a golf course, but the techniques would be the same in a landscape.
Recently, root knot nematodes have become a bigger problem in turf and the sample needed by the lab is roots.

Deer Damage

If you notice damage to plants in a landscape, and you think deer might be the culprit, there are a few signs you can look for. Damage to plants that is high off the ground is one indicator that deer may be to blame. Deer can reach various parts of plants as high as 6 feet up from the ground, a height that generally rules out other animals. The appearance of the damage is another good indicator of what kind of animal is doing the chewing. Damage done to plants by deer leaves ragged ends on twigs, stems, and leaves because deer don't have upper incisors. This lack of upper incisors means deer tear or jerk away the plant material they are eating. For a broader look at the damage various animals can do to plants, read the UF/IFAS publication, "How To Identify the Wildlife Species Responsible for Damage in Your Yard."
 
Fencing off the landscape, or parts of your landscape is one way to protect your plants from deer. Permanent fencing options vary widely in cost, so you may want to look into a few options before deciding if fencing off areas from deer is feasible for your landscape.
 
While a variety of deer repellents can be found on the market, it is important to note that these rarely completely eliminate deer damage. The efficacy of repellents will vary depending on factors like your location, availability of food for deer, and the number of deer in the area. This, coupled with the high monetary and labor cost of repellent application, makes the use of these products a better short-term option rather than long term. Instead of investing time and money into repellent application, many people who experience repeated deer damage choose to look for plants that are naturally deer resistant.
 
Deer feeding preferences will vary by area, so finding a "deer proof" plant is less an exact science and more of a trial and error guessing game. While truly deer proof plants are hard to identify, there are a number of plants that have been determined to be deer resistant. For a comprehensive list, see the UF/IFAS publication, "  Ornamental Plant Susceptibility to Damage by Deer in Florida."
