Diseased leaves weaken tree vitality, and the weakened tree is turn yellow or brown and drop in the early more susceptible to winter injury and growth stages. Fruit and twigs rarely get opportunistic diseases. The disease is infected.

The Phylogeny of Plant and Animal Pathogens in the Ascomycota
Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus. -

Peach Leaf Curl and Plum Pockets
report on RPD No. 821 PLANT December 2017 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN PEACH LEAF CURL AND PLUM POCKETS Peach leaf curl, caused by the fungus Taphrina deformans, has been reported from most of production areas of peaches and nectarines in the world. It is an important disease of peaches and nectarines in Illinois. In home plantings, this is one of the most common diseases. Commercial peach orchards are sometimes seriously damaged when a dormant fungicide application has not been made. Plum pockets also occurs worldwide. This disease is caused by the fungi Taphrina communis and in some areas by T. Pruni. Plum pockets attacks a number of cultivated and wild species of plums. Neither peach leaf curl nor plum pockets normally kills trees, but both may leave them in a weakened condition and, thus, more susceptible to winter injury and infection by other disease-causing organisms. The fruit crop is reduced for the following year, or even longer. Both diseases are discussed here because their management and conditions for their development are the same. Disease development is favored by cool, moist weather (frequent light showers) during the buds break dormancy in early spring. Symptoms Leaves. Infected leaves are severely puckered, distorted, thickened, crisp in texture, and curled downward and inward within a month after full bloom (Figure 1). Usually the whole leaf is affected. Such leaves lose their normal green color, which is replaced by red and purple tints. Later, a grayish white “velvet” spore-producing layer of the Taphrina fungi covers the upper surface of diseased areas. -

L. (Rosaceae)] for consumption from continental Spain into the continental United States. Based on the scientific literature, port-of-entry pest interception data, and information from the government of Spain, we developed a list of all potential pests with actionable regulatory status for the continental United States that are known to occur in continental Spain and that are known to be associated with the commodity plant species anywhere in the world. From this list, we identified and further analyzed 9 organisms that have a reasonable likelihood of being associated with the commodity following harvesting from the field and prior to any post-harvest processing.

Peach Leaf Curl, If Uncontrolled, Can Be a Serious Disease in Most of the Peach-Growing Areas of the World
Plant Pathology Circular No. 55 Florida Department of Agriculture March 1967 Division of Plant Industry PEACH LEAF CURL, TAPHRINA DEFORMANS (BERK.) TUL. OF PEACH, PRUNUS PERSICA (L.) BATSCH Harry C. Burnett, Plant Pathologist Peach leaf curl, if uncontrolled, can be a serious disease in most of the peach-growing areas of the world. This disease is important in all peach- growing areas of the United States except in the irrigated sections of Washington and the semi-arid regions of the Southwest. The peach leaf curl organism also attacks nectarines, apricots and almonds. Low temperatures and wet weather at the time when new leaves are opening from the bud appear to favor the peach leaf curl disease (2). In Florida unsprayed trees have shown little or no disease, and to date peach leaf curl has been of minor importance (3). In February 1966 approximately 150 unsprayed peaches of the Bonita variety in 5 gal containers were observed showing moderate to severe symptoms of peach leaf curl. SYMPTOMS. Peach leaf curl is generally confined to the new growth of leaves, blossoms, twigs, and fruit. With the onset of new growth in the spring, the diseased leaves are curled, arched, puckered, and distorted. The affected tissue is much thickened and very firm. The leaf margins curl inward so that the undersurface of the leaf is a series of concave chambers (Fig. 1). In some cases the entire leaf shows these symptoms, although it is not uncommon for small portions to be affected. Peach leaf curl symptoms may be minor, wherein only a few leaves may show distortion, to very severe with practically all of the foliage affected. -
