Perceptions and knowledge regarding the COVID-19 pandemic between U.S. and China: a mixed methods study.

Background: SARS-CoV-2, a new coronavirus first reported by China on December 31st, 2019, has led to a global health crisis that continues to challenge governments and public health organizations. Understanding COVID-19 knowledge, attitudes, and practices (KAP) is key for informing messaging strategies to contain the pandemic. Cross-national studies (e.

Stimulatory Effects of Sublethal Doses of Carbendazim on the Virulence and Sclerotial Production of .

Stimulatory effects of low doses of fungicides on the virulence of phytopathogens have profound implications for applications of fungicides. The present study demonstrated that carbendazim sprayed at 0.001 to 0.

Stimulatory Effects of Flusilazole on Virulence of Sclerotinia sclerotiorum.

Flusilazole, a member of the demethylation inhibitor fungicides, is highly efficacious for control of Sclerotinia sclerotiorum. To achieve judicious applications of flusilazole, its hormetic effects on virulence of S. sclerotiorum were investigated.

Hormetic Effects of Carbendazim on the Virulence of Botrytis cinerea.

The ascomycete plant-pathogenic fungus Botrytis cinerea infects more than 1,400 plant species worldwide. Stimulatory effects of sublethal doses of fungicides on plant pathogens are of close relevance to disease management. In the present study, stimulatory effects of carbendazim on the virulence of B.

Hormetic Effects of Mixtures of Carbendazim and Iprodione on the Virulence of Botrytis cinerea.

Hormetic effects of fungicides on mycelial growth and virulence of plant pathogenic fungi have been reported, but the effects of fungicide mixtures on virulence hormesis of plant pathogens remain to be investigated. In this study, hormetic effects of mixtures of carbendazim and iprodione on the virulence of two carbendazim-resistant isolates of Botrytis cinerea were determined. Spraying carbendazim alone at 3 to 800 μg/ml exhibited hormetic effects on virulence to cucumber leaves, and carbendazim at 10 μg/ml had the maximum stimulation of 16.

Hormetic Effects of Trifloxystrobin on Aggressiveness of Sclerotinia sclerotiorum.

Sclerotinia sclerotiorum is a devastating ascomycete plant pathogen with an extremely wide host range. Fungicides are still the mainstay for control of this pathogen, and stimulations to mycelial growth and aggressiveness by subtoxic doses of fungicides carbendazim and dimethachlon have been reported. The present study assessed hormetic effects of the quinone outside inhibitor (QoI) fungicide trifloxystrobin on aggressiveness of S.
