Grass I know, bushes and trees I don't. Need some help with an ID on this bush/tree for a client.
Thanks for the help.

Thanks X-Terminator, from my internet research that was my best guess so far.

drsogr..I am sure there are alot of things in this world you have not seen yet.

LOL....why do you have to be so mean? So what if I haven't seen a lot of bush.

I am as nice as nice can be

this used to be a wonderful screen planting in our area. They have had battles with disease that make them not a hardy planting in central NC

yep, that's what they are. i am familiar with them in the more diseased state as all of them around here seem to be dying.

you can fight the disease if you keep them sprayed, I found a chemical for my mother's hedge, and I can't remember if it was a fungus or what was killing them off. But she sprayed the bushes regularly and they survived. Still healthy today and this problem was a few years back.

Entomosporium Leaf Spot on Red Tip
Ronald K. Jones, Plant Pathologist (retired)
Mike Benson, Plant Pathologist
Leaf spot, caused by the fungus Entomosporium maculatum, is a widespread and destructive disease of red tip (Photinia fraseri), loquat (Eriobotrya japonica), India hawthorn (Rhaphiolepis indica), some pear cultivars (Pyrus sp.) and several other members of the rose family. This disease is most damaging to plants in the landscape and nurseries during periods of cool, wet weather and when active growth is occurring.
Entomosporium leaf spot on red tip.
Tiny, circular, bright red spots on both the upper and lower surfaces of young expanding leaves are the first symptoms of Entomosporium leaf spot. Numerous small spots may coalesce into large maroon blotches on heavily diseased leaves. Leaf spots on mature leaves have ash brown to light gray centers with a distinctive deep red to maroon border. Tiny black specks, spore producing bodies of the fungus, can often be observed in the center of each leaf spot. Spots similar to those on the leaves can develop on leaf petioles and tender stem growth during prolonged periods of cool, wet weather.
Low levels of leaf spot usually cause little more than cosmetic damage but maintain a source of spores for future infections. Severe infections, however, often result in early and heavy leaf drop. Heavy leaf drop severely reduces the landscape value of red tip and can cause plant death. Some cultivars of India hawthorn are as severely affected as red tip.
Spots on the leaves and young shoots are important in the survival of the Entomosporium leaf spot fungus. Fallen, diseases leaves are less important sources of the fungus. Masses of spores are released during periods of wet weather from the fungal spore producing structures in the center of the spots from late winter through much of the year except during the hot periods of summer. These spores are spread to healthy foliage by a combination of splashing water and wind. New leaf spot symptoms appear within 10-14 days after a wet infection period.
For the landscape, purchase plants showing no leaf spot symptoms. Isolated healthy plants or hedges can often remain healthy as the spores are only splashed over short distances. Space plants to improve the air movement around the plants and promote rapid drying of leaf surfaces. If it is necessary to irrigate the plants, do not wet the foliage or irrigate in midday to reduce the period of time foliage remains wet. If possible, remove fallen diseased leaves. Do not water or fertilize plants any more than necessary to avoid promoting excess new growth. Also, reduce pruning during the summer which promotes continual new growth. Severely defoliated plants may need to be pruned heavily to have a small, easier to spray plant, to reduce the source of spores and improve air movement. It may be necessary to remove severely diseased plants that have also been damaged by cold injury and replace them with another plant species that is not susceptible to leaf spot.
Several fungicides may also be help in the management of leaf spot in the landscape.
Fungicides Recommended for Entomosporium Leaf Spot Control
Fungicide Rate per gallon Rate per 100 gallons
Banner 1 tsp. 12-20 fl. oz.
Daconil 2787 75W* 1 1/2 tbs. 1 1/2 lb.
Daconil 2787 4.1F 2/3 tbs. 2 pt.
Chlorothalonil* see label see label
Fore 80W 3/4 tbs. 1 1/2 lb.
Bayeleton 25W** 2 tsp. 1/2 - 1.0 lb.
Funginex EC* see label see label
*Available in small packages.
**Repeated applications may cause some injury.
This disease is very difficult to control after plants are severely infected. During extended cool, wet periods, protective sprays may be necessary. Where leaf spot is a problem, applications of one of the above fungicides should begin as new growth starts in the spring with additional sprays at 10 - 14 day intervals until mid-June. Make applications at 10 day intervals during cool, wet periods and at 14 day intervals during drier periods. Fungicide applications should not be necessary during hot, dry periods. It may also be helpful to make 3-4 applications from mid-October to late November if wet weather prevails.
