“…dothidea , F. proliferatum, C. siamense, and C. gloeosporioides, which caused gray mold and brown rot in fresh walnut fruits, have been isolated. Pinter et al reported [ 26 ] that in Hungary, walnut trees were mainly infected by Phomopsis , Diplodia , Cytospora, and Phoma spp., while walnuts were primarily infected by Xanthomonas and Gnomonia spp. during storage.…”

Biological control by antagonistic microorganisms are an effective and environmentally friendly approach in postharvest disease management. In order to develop a biocontrol agent for fresh walnut fruit preservation, the potential biocontrol effects of Bacillus amyloliquefaciens RD.006 and Hanseniaspora uvarum FA.006 against the main fungal pathogen of walnuts were evaluated. Botryosphaeria species showed the highest detection, and the JNHT01 strain showed the strongest pathogenicity. Bot. dothidea JNHT01 caused gray mold and brown rot on fresh walnuts, and its incidence rate reached 100% after an 8 days incubation. The growth of this fungal strain can be promoted by lighting, with a maximum growth rate achieved at a pH of 7 and at 28 °C. B. amyloliquefaciens RD.006 and H. uvarum FA.006 supernatants at a concentration of 1–15% v/v showed antifungal activity. The mycelial growth inhibition rates of Bot. dothidea JNHT01 were 23.67–82.61% for B. amyloliquefaciens RD.006 and 1.45–21.74% for H. uvarum FA.006. During Bot. dothidea JNHT01 growth, the biomass, nucleic acid leakage, and malondialdehyde content gradually increased, while the DPPH scavenging capacity and SOD activity decreased. The B. amyloliquefaciens RD.006 and H. uvarum FA.006 strains showed antifungal activity by damaging fungal cell membranes and reducing fungal antioxidant activity. Moreover, the antifungal effect of B. amyloliquefaciens RD.006 was higher than that of H. uvarum FA.006. Hence, the RD.006 strain of B. amyloliquefaciens can be considered a potential biocontrol agent for the management of postharvest walnut diseases caused by Bot. dothidea.

“…An illustrative U.S. example concerns the middle and lower Mississippi River, wherein different flood risk assessments result from the application of flood stage versus flood discharge time series. 29 For the Missouri River, channelization during the past ~100 years has caused channel capacity losses. At measurement stations spanning Ͼ1000 km from the lower Missouri to the middle Mississippi rivers, increases of up to 3-4 m (in flood stage, for the same discharge) have been linked to the construction of navigational engineering structures and levees.…”
