“…Additionally, calcium amendments in soils with low calcium content have been shown to decrease susceptibility of tubers to soft rot (Ngadze et al 2014). While most commercial potato cultivars are susceptible to soft rot, cultivars with less susceptibility towards blackleg and soft rot have been uncovered in various studies (Lyon 1989;Chung et al 2013). However, reliable screening for cultivars that are less susceptible to blackleg and soft rot is not trivial due to the influence of environmental factors on disease development (Czajkowski et al 2011;Gill et al 2014).…”

“…Pectobacterium carotovorum subsp. Carotovorum, Pcc (Family: Enterobacteriaceae; Class: Gamma Proteobacteria) is soft rot bacteria and favored by low temperature and moist conditions (Chung et al, 2013). The Pectobacterium as is facultative anaerobe, no spore-forming, gram-negative enter-bacteria that cause disease in several vegetable crops (Agrios 2005).…”

In the current study, we formulated and characterized bio-based oil in water nanoemulsions incorporating monoterpenes; (R)-carvone, cinnamaldehyde, citral, geraniol and pulegone and tested their antimicrobial activity against two plant pathogenic bacteria, Pectobacterium carotovorum sub carotovorum and Ralstonia solanacearum in vitro and in vivo studies. Nanoemulsions (NEs) were prepared by adding dropwise monoterpenes at concentration of 5% in an aqueous solution containing 10% a surfactant (tween 80) with constant stirring and then ultrasonication. NEs were confirmed by dynamic light scattering and transmission electron microscopy. Physical stability and viscosity were, also, investigated. NEs monoterpenes had a poly dispersity index ranged from 0.130 to 0.630 and droplet size in the range of 56.64-176.00 nm. Results revealed that NEcinnamaldehyde had great antibacterial activity against P. carotovorum and R. solanacearum (MIC = 60 and 100 mg/L, respectively). NE cinnamaldehyde was induced effective defense responses in vivo in potato plant and tubers against two tested bacteria at a rate 1000 and 3000 mg/kg. Higher activities of polyphenoloxidase (PPO), peroxidase (POD) activities and total phenolic content of tubers and leaves were significantly recorded compared to control at all tested times. This was evident from reduced soft and brown rot diseases symptoms of potato spunta cv treated with elicitors subsequently with tested bacteria. These results showed that the PPO, POD and total soluble phenols play a role in instructing resistance to potato soft and brown mold infections. The observed relationship between formulation and activity can lead to the rational design of nanoemulsion based systems for monoterpenes for applications in antimicrobial and agrochemical industries. Amalgamation of such economical treatments might lessen management costs and minimize the environmental pollution.

“…Effect of pH on phage activity was done according to [23], with some modifications. Each isolated phage was incubated in buffer of different pH values (1,2,3,4,5,6,7,8,9,10,11,12) at 5°C for 24 h. Double layer assay was done and the number of plaques was counted after to determine the optimum pH for phage activity. This test was done in triplicates and repeated twice.…”

Potato crop is one of the most economically important crops, and is considered as the fourth main food crop in the world. One of the most important serious diseases of potato is bacterial soft rot disease. In our study, soil samples were collected from potato rhizosphere from a potato cultivated field in Giza, Egypt. Two bacteriophages were isolated on Kosakonia sacchari as a host, causing potato soft rot disease. Based on the genome characterization and electron microscopy, the two phages were named as vB_KsaM-C1 belonging to Myoviridae and vB_KsaO-C2 belonging to Microviridae. Both phages sustained their activity more than 20 months with a remarkable decrease in phage titre. In addition both recorded the same TIP at 65°C and showed the optimum activity at pH 7. The DEP of vB_KsaM-C1 was 10-7, while that of phage vB_KsaO-C2 was 10-9. A small scale application of the two isolated bacteriophages on infected potato tubers discs, in the lab, successfully inhibited bacterial soft rot caused by Kosakonia sacchari.
