Plant Pathology Science

In last decades, development of Biology science, importance of protection of environmentand high demand to the nutrients is caused that usage of the biological materials, in order to increase crop yield, have been viewed by researchers. Some of the Bacilli, Rhizobia and Trichoderma species are distinguished as Plant Growth Promoting. These micro-organisms with colonization and abundant sporulation in soil especially in rhizosphere of most of the cultivated and non-cultivated plants not only decrease the pathogenic agents, but also increase growth of the plants by bio-chemical mechanisms. With attention to isolate and study of many Trichoderma species in Iran, importance of performance researches about plant growth promoting effects of theTrichoderma species is necessary. In this paper, review of the plant growth promoting effects of Trichoderma is presented.

Anthracnose disease is one of the most destructive diseases of strawberry which caused by Colletotrichum acutatum, C. gloeosporioides and C. fragariae.  C. acutatum and C. gloeosporioides species complexes possess wider host range. According to the latest multi-gene phylogenetic evaluation, different strains of the causal agent of strawberry anthracnose disease which have been collected from different regions of the world, belong to these two species and are divided into several clusters, related to cryptic species. Despite infecting various parts of the plant, C. acutatum is mostly responsible for fruit rot and in comparison with two other species, causes crown rot and is more prevalent and destructive. Dispersal of pathogen inoculums mainly takes place by rain splash and sprinkler irrigation as well as by movement of human beings and animals. Integrated management of this disease is mainly achieved through cultural, chemical, biological and the use of resistant cultivars. Giving the importance of strawberry anthracnose disease in terms of damage rate and its recent incidence in many strawberry growing areas in Iran, different aspects of the disease, including diagnosis of the causal agent, biology and efficient management methods are discussed in the present review.
