    Apricot, Prunus armeniaca is a deciduous tree in the family Rosaceae grown for its edible fruit. The apricot tree is has an erect growth habit and a spreading canopy. The leaves of the tree are ovate with a rounded base, pointed tip and serrated margin. The tree produces white to pink flowers, singly or in pairs, and a fleshy yellow to orange. Infected trees leaf out prematurely. The disease is spread by grafting and feeding by the plum leafhopper Macropsis trimaculata (Fitch). After infection, it may be 40 days to three years before disease symptoms are visible. Use only bud wood from healthy trees and destroy any trees which show typical disease symptoms.

    Affects: apricot trees, cherry trees, peach trees, plum trees, nectarine trees Description: Brown rot infects stone fruit blossoms, stems and fruit. During summers with higher-than-average rainfall, young fruit that is damaged by insect chewing will develop this condition. Brown rot is a fungal disease that commonly affects stone-fruit trees, including peach trees, especially after a long, warm, wet spring. It is one of the most common peach-tree diseases. It affects the fruit tree’s flowers and fruit crop, but is not fatal. Fortunately, brown rot is easy to spot, prevent, and treat.

    Stone fruit diseases are successfully managed by the combined use of cultural, chemical and biological measures supplemented with the cultivation of resistant cultivars. Foliar diseases are effectively controlled by timely sprays of fungicides. Proper pruning, applying chemicals and antagonist effectively manage canker and by: 4.   There are few diseases of fruit trees that can be as devastating as bacterial blast, the disease affecting stonefruit trees that is also known as .

Shot hole disease on stone fruit trees There is increasing number of leaf samples collected from cherry, peach or plum arriving at my office this year. Those samples had the same problem: shot hole disease. The name of shot hole implies that the symptom of the disease looks like gun shots.

Bul. ] Shot-Hole Disease of Stone Fruit Trees 35 SUMMARY AND CONCLUSIONS This paper describes the symptoms of the peach blight or shot-hole dis- ease occurring on peach, almond, and apricot.

Although attacking twigs, dormant buds, leaves, blossoms, and fruit, the disease varies considerably in its severity on different organs of these three stone fruits.

Shot hole disease, survival and pathogenicity of the causal agent on stone fruit trees of North East Iran Samples taken from trees where shot-hole disease levels were high during the growing. Keywords: Shot-hole disease, overwintering, virulence, stone fruit shoots Introduction 12 Shot hole disease is one of the major foliar diseases of Prunus species worldwide which is caused by several pathogens and particularly by Wilsonomyces carpophilus (Adaskaveg et al., ).

The fungus was first observed on peach trees in France inlater in Africa, Asia, Europe, North, Central and.

Study on Fungal Agents Causing Shot Hole Disease on Stone Fruit Trees in. Shot hole, or Coryneum blight— Wilsonomyces carpophilus. Shot hole disease affects Prunus spp. Hosts include almonds, Catalina and Japanese flowering cherries, English laurel, ornamental plums, nectarines, peaches, and especially apricot.

The disease will develop on cherries, plums, and prunes only when growing near more susceptible hosts during years with unusually wet weather. Shot hole disease attacks almonds, apricots, nectarines, peaches, plums and prunes.

Ornamental flowering peach and plum trees are often affected as severely as the fruit trees. Most people recognize shot hole in spring, when it causes spots or lesions on buds, leaves, twigs and fruit.

The disease can be quite severe following warm, wet winters File Size: 46KB. The guy at the nursery said the disease is called “shot hole” but wasn’t sure how to control it. Do you know. A: Shothole is a common bacterial disease on ‘Otto Luyken’, ‘Zabal’ and ‘Schip’ laurel plants.

The diseases’s name is descriptive of the symptoms: it looks like someone shot the shrub with a shotgun.

Shot hole disease, which may also be known as Coryneum blight, is a serious issue in many fruit trees. It is most commonly seen in peach, nectarine, apricot, and plum trees but may also affect almond and prune trees. Some flowering ornamental trees can be affected as well.

Shot hole disease (also called Coryneum blight) is a serious fungal disease that creates BB-sized holes in leaves, rough areas on fruit, and concentric lesions on branches.

The pathogen that causes shot hole disease is Wilsonomyces carpophilus. one stone fruit tree in their yard. A number of serious fungal, bacterial, nematode, and viral diseases are common to stone fruits and should be of concern to all growers.

Symptoms of several common diseases and their control measures are discussed. Fungal Diseases Brown Rot Brown rot is a very destructive disease of all stone fruits.

Black leaf spot, also sometimes known as shot hole disease, is a problem that affects all stone fruit trees, including cherries. It isn’t as serious on cherries as it is on some other fruit trees. best control of shot hole disease. Keywords: Stone fruit trees, shot- hole, Stigmina carpophila, disease management.

INTRODUCTION. Shot-hole disease of stone fruits, caused by S. carpophila (Lev.) (Adaskaveg et al., ) is a serious disease of Prunus species in many temperates to semi-arid regions of the world.

Identify the problem Shot hole is a symptom of fungal and bacterial disease of stone fruit causing small spots that turn dark and eventually die. In the Zurich district of Switzerland the shot hole disease of cherries [Clasterosporium carpophilum[Stigmina carpophila]: see preceding abstracts] has been well controlled by a pre-blossom application of 10 per cent.

On the leaves appears circular spots in whose right the tissue brunifies, and finally it breaks away from the rest of the leaf. Shot hole disease is one of the most important diseases of stone fruit trees in Iran.

The disease is wide spread among orchards of Prunus spp. During spring and summer of80 monoconidial isolates of the pathogen were recovered from infected leaves, fruits and twigs of different Prunus spp. in West Azerbaijan, Tehran, Ghazvin and Razavi Khorasan provinces of Iran and were Cited by: 4.

Spots on young leaves usually fall out, leaving a hole (the shot hole); older leaves retain their lesions. Fruit spots are small with purplish margins, slightly corky, and raised. Spots are found on the upper surface of fruit with respect to the way it hangs on trees.Bacterial spot of stone fruit | Primefact 76 3 Examination of nursery trees On receiving trees from a nursery it is important to inspect them for cankers.

Pruning and shaping trees Pruning to allow thorough spray penetration and more rapid drying of the canopy helps to reduce the severity of the disease.The table below lists plant host, disease common name, scientific name, and disease type for pests included in this Web site.
