Root and crown rot is an important disease in Kohgiluyeh and Boyerahmad province peach orchards. Its signs are wilting, general weakness, loss of foliage and sometimes sudden wilt and death of the tree. To isolate the pathogen, used corn meal-agar with antibiotics, Delvasid, Ampicillin and rifampicin medium. Pathogen is Phytophthora cactorum. For pathogenesis test, 2 inoculation methods, to a tree branch or contaminated soil around the roots and crown of seedling is used. Inoculation roots and crowns of seedlings and saplings of six varieties of peaches with this pathogen, showed that Takheh is resistant, Alberta, Redhoon and Mashhad red peach are semi-resistant, Angiri and J.H.Hill are sensitive to the disease

Dastjerdi R., Nadi S. and Damyar S. 2018. Sooty canker of fruit trees in Iran. Plant Pathology Science 7(1):15-27.
Neofusicoccum mangiferae is the causal agent of branch wilt, blossom blight, canker and dieback on a variety of fruit trees such as almond, hazelnut, apricot, peach, citrus, grape and apple. Cracking and peeling of thin outer layer of bark and exposing black sooty mass of spores is a characteristic feature of disease. Pathogen causes gradual declining and sometimes complete death of trees. The fungus infects the hosts through wounds, created by pruning, frost damage, drought stress, or bark cracks caused by sunburn and develops under hot and sunny weather in summer. Good sanitation, fertilization of trees, adequate irrigation, appropriate pest control, preventing wounds, and avoiding unnecessary pruning are the methods for disease management.

Sadeghi Garmaroodi H, Seyed Masoumi SY, Nankali A (2022) The reaction of thirteen peach and nectarine cultivars to Verticillium wilt. Plant Pathology Science 11(1):60-73.                  Doi: 10.2982/PPS.11.1.60.
Introduction: Verticillium wilt, caused by Verticillium dahliae, is one of the most important soil-borne diseases of stone-fruit trees. Materials and Methods: Samples showing evidence of Verticillium wilt were collected from stone fruit orchards in the suburbs of Shahroud and Damavand and four isolates of V. dahliae were obtained. The fungal inoculum was prepared on sterile wheat grains and the response of 13 peach and nectarine cultivars propagated by grafting on GF305 (almond-peach hybrid) rootstock was inoculated with it in the canopy area in the garden in early spring. Sixteen weeks after inoculation, disease severity was recorded on a three-point scale. Results: All peach and nectarine cultivars were classified as very susceptible, susceptible, or semi-susceptible and none of them showed resistance. The Nectarine Independence cultivar was highly susceptible to disease, while the peach cultivar had the lowest disease severity index and was therefore classified as semi-susceptible. Conclusion: Among these cultivars, the Romestar peach cultivar is less susceptible to the disease.
