Species: Excellent Biocontrol Agents against Tomato Diseases.

Tomatoes encounter many pathogens, such as fungi and bacteria, which reduce the yield and quality of plants and lead to large losses in production. The application of plant protection products (PPPs) is still an important and most effective measure to control plant diseases. However, the use of chemicals in agriculture contributes to environmental pollution and biodiversity loss, and it can also threaten non-target living organisms.

First Report of pv. Causing Bacterial Blight on Hazelnut Tree () in Montenegro.

Hazelnut is a minor but rapidly increasing commercially grown species in Montenegro. In June 2021, severe infection, affecting more than 80% of the trees, was observed on 6-year-old hazelnut plants () cultivar Hall's Giant, in a 0.3ha plantation near Cetinje, central Montenegro.

Characterization of Strains Associated with Shoot Blight of Raspberry and Blackberry in Serbia.

During May 2016, severe blight symptoms were observed in several raspberry and blackberry fields in Serbia. In total, 22 strains were isolated: 16 from symptomatic raspberry shoots, 2 from asymptomatic raspberry leaves, and 4 from symptomatic blackberry shoots. Additionally, eight raspberry strains, isolated earlier from two similar outbreaks, were included in the study.

Isolation, Characterization and Draft Genome Analysis of Bacteriophages Infecting .

Bacterial fruit blotch and seedling blight, caused by , is one of the most destructive diseases of melon and watermelon in many countries. Pathogen-free seed and cultural practices are major pillars of the disease control. However, use of bacteriophages as natural biocontrol agents might also contribute to the disease management.

Complete Genome of the Specific Bacteriophage KΦ1, Its Survival and Potential in Control of Pepper Bacterial Spot.

phage KΦ1, a member of family, was isolated from the rhizosphere of pepper plants showing symptoms of bacterial spot. The phage strain expressed antibacterial activity to all strains tested and did not lyse other spp., nor other less related bacterial species.

Agrobacterium arsenijevicii sp. nov., isolated from crown gall tumors on raspberry and cherry plum.

Two plant-tumorigenic strains KFB 330(T) and KFB 335 isolated from galls on raspberry (Rubus idaeus) in Serbia, and a non-pathogenic strain AL51.1 recovered from a cherry plum (Prunus cerasifera) tumor in Poland, were genotypically and phenotypically characterized. Phylogenetic reconstruction based on 16S rDNA placed them within the genus Agrobacterium, with A.

Draft Genome Sequences of Agrobacterium nepotum Strain 39/7T and Agrobacterium sp. Strain KFB 330.

Tumorigenic strains of Agrobacterium spp. are responsible for crown gall disease of numerous plant species. We present here draft genome sequences of nonpathogenic Agrobacterium nepotum strain 39/7(T) (CFBP 7436(T), LMG 26435(T)), isolated from crown gall tumor on Prunus cerasifera, and tumorigenic Agrobacterium sp.

A novel plasmid pEA68 of Erwinia amylovora and the description of a new family of plasmids.

Recent genome analysis of Erwinia amylovora, the causal agent of fire blight disease on Rosaceae, has shown that the chromosome is highly conserved among strains and that plasmids are the principal source of genomic diversity. A new circular plasmid, pEA68, was found in E. amylovora strain 692 (LMG 28361), isolated in Poland from Sorbus (mountain ash) with fire blight symptoms.

A New View of Sooty Blotch and Flyspeck.

Sooty blotch and flyspeck (SBFS) fungi colonize the surface wax layer of the fruit of apple, pear, persimmon, banana, orange, papaya, and several other cultivated tree and vine crops. In addition to colonizing cultivated fruit crops, SBFS fungi also grow on the surfaces of stems, twigs, leaves, and fruit of a wide range of wild plants. The disease occurs worldwide in regions with moist growing seasons.
