February and Two Weeks from Spring - Ready or not here it comes!

We are back from the trade show and doing all the follow-up activities from the seminars and returning phone calls and to do's that were left in the stack in order to get ready for GSHE (which was great!). We had about 450 people attending our seminars. The evaluations were very good. If you missed the educational sessions and the education on the Trade Show floor, I am sorry. It is an expense and time away from work but I always come away recharged with new ideas.

We are already planning for next year and trying to determine what areas of horticulture we should concentrate on or what speakers you would like to hear. This is your educational program and we want to tailor it to your needs. Let us know. If you have some great information you would like to share, we will try to work you into the program. We always have comments that we need to increase the number of growers and in-the-ditches people on the program to balance the academics. However, most growers are modest and think everyone is doing things just as well as they are. They are not sure they have that much to share. This is not true. Everyone likes to hear another grower or landscaper share their successes and failures. It is nice to know that you share the same concerns and probably have some answers. Let us know if you would like to offer some time on a panel or share some thoughts about your landscape, nursery, or greenhouse company.

Below you will see a list of LANDSCAPE HINTS that I collected from landscapers and faculty a couple of years ago. I asked them what are some basic hints that everyone should remember going into a landscape job. The list below is what emerged from the responses. We published the hints in the newsletter quite a while ago so it's time for a repeat performance.

This is a short newsletter but I am sure the buds are swelling, the trucks are revved-up and the the herbicide needs to be out now! The break is over for some and the Spring frenzy begins!


HELPFUL HINTS FOR SUCCESSFUL LANDSCAPES

GREAT URBAN FORESTRY SITE

We haven't reviewed a website in a long time. Ken found this site on trees hosted by urban forester Dr. Kim Coder at the University of Georgia. It has a great FAQs area. The URL is:

PLANT PATHOLOGY REPORT

AUBURN PLANT DISEASE REPORT - DECEMBER 2003
Jackie Mullen
Extension Plant Pathology Specialist

As usual, December was a relatively quiet month with respect to plant samples: 26 plant samples were received.

Diseases seen in December included anthracnose, Fusarium, and Phomopsis leaf spots/blotches on Boston fern; and Phytophthora root rot on juniper; Bipolaris seedling disease and seed rot of bermuda; bacterial leaf spot of flowering cherry; anthracnose on lavender; Cercospora leaf spot on oleander; and Pythium blight on bentgrass. In November we received red maple, holly, and live oak, and southern magnolia which all showed trunk cankers. Culture work on all except the magnolia produced Botryosphaeria fungal isolates. We suspect the magnolia canker may also be a Botryosphaeria problem.

The brown leaf spots/blotches on the fern were associated with the three fungi, Colletotrichum, Fusarium, and Phomopsis. Some root damage was also present but culture work did not indicate a root disease. Root abiotic stress damage may have caused an increase in foliage susceptibility to disease.

The juniper showed foliage yellowing on inner and lower branches. Root decay produced a Phytophthora isolate in culture. Damaged junipers should be removed. Watering practices should be examined and reduced if appropriate. In greenhouse/nursery situations, a protective fungicide drench treatments should be applied (See ANR-1173 or check the web site http://www.aces.edu/pubs/docs/A/ANR-1173/ANR-1173.pdf ).

BIRMINGHAM PLANT DISEASE REPORT - DECEMBER 2003
J. Jacobi
Extension Plant Pathology Specialist

The lab received a total of 11 samples during the month of December. The most common problem seen last month was fungal canker diseases of woody ornamentals. For more information on canker diseases of Leyland Cypress see ANR-1160 http://www.aces.edu/pubs/docs/A/ANR-1160/. General information on the identification and control of several other dieback and canker diseases can be found at the following web site http://www.ipm.uiuc.edu/diseases/series600/rpd636/.

Pansy root and soil problems were the other main problems seen last month. Above ground symptoms of Black and Pythium root rot are similar. One of the first above ground symptoms is yellowing of the lower leaves. Root symptoms are different for each disease, but typically require laboratory study for exact diagnosis. For a complete description of both diseases including control recommendations see ANR-1214, Diseases of Pansy and Their Control http://www.aces.edu/pubs/docs/A/ANR-1214/ANR-1214.pdf.

Disease Possibilities for January
In January, brown patch on turf grasses may be problems. Pythium blight/root rot may occur on cool-season grasses; this is mostly a problem on golf course areas. Black root rot (Thielaviopsis basicola) may occur on pansies and container hollies. Botrytis is a common problem on greenhouse crops.

In November, December, and early January we have seen Corynespora cassiicola. C. cassiicola has a large host range which includes vegetables and many ornamentals.
