The Effect of Nano-Silver Liquid against the White Rot of the Green Onion Caused by Sclerotium cepivorum
نویسندگان
چکیده
White rot, which is caused by Sclerotium cepivorum, is a lethal disease affecting green onions. Three different types of nano-silver liquid (WA-CV-WA13B, WA-AT-WB13R, and WA-PR-WB13R) were tested in several different concentrations on three types of media to assess their antifungal activities. Results from in vitro experiments showed that all three of the nano-silver liquids had more than 90% inhibition rates at a concentration of 7 ppm. Greenhouse experiments revealed that all of the nano-silver liquids increased biomass and dry weights, and there were minimal changes in the population of various bacteria and fungi from the soil of greenhouse-cultivated green onions. In addition, a soil chemical analysis showed that there were minimal changes in soil composition.

Developing New Integrated Strategies for Controlling White Rot in Garlic
White rot caused by Sclerotium cepivorum Berk is a significant threat to garlic and onion industry in the United States. The pathogen produces a great number of poppy seed-sized sclerotia, which can survive in soil for many years. Populations of just a few sclerotia per liter soil can potentially cause severe disease and result in crop failure. Once the land has been infested, it is generally c...

Metallic silver nanoparticles have been reduced from silver nitrate by employing the extracellular enzymatic machinery of edible White button Mushroom (Agaricus bisporus). The physical properties of these particles, size and shapes have been determined using techniques like TEM, FTIR and XRD and were reported in our earlier report. But, what stands of paramount importance in the presen...

متن کاملThe degradation of onion cell walls by extracellular enzymes of Botrytis allii and Sclerotium cepivorum [proceedings].
Botrytis allii and Sclerotium cepivorum, which respectively cause neck rot and white rot of onions, produce a range of cell-wall-degrading enzymes in onion tissue (Hancock et al., 1964; Beck, 1976). The two fungi have been grown on liquid media using purified onion cell walls, prepared by an adaptation of the method of Jarvis et al. (1977), as the sole carbon source for B. allii and the major c...
