The actual yield losses due to early blight disease in potato worldwide are not well described, and therefore, we analysed a decade-long series of field trials performed in Sweden. The series involved 18 trials with starch potato and six ware potato trials where early blight infection rate and yield were studied in untreated and fungicide-treated plots. Yield loss was estimated as the difference between the best fungicide stra...

Integrated pest management (IPM) is an important tool for sustainable crop production. IPM includes a diversity of methods, e.g., the use of biological control agents (BCAs) for disease control or growth promotion. While there is an increasing interest in the use of BCAs, less is known about their environmental costs and benefits on wild species, such as wild crop relatives. For example, a BCA may have the positive effect of c...

Alternaria solani is causing early blight and thereby yield reduction in the potato production. The pathogen is today mainly controlled by fungicide applications. The severity of early blight can vary largely among fields. The aim of this study was to gain understanding of what field and management parameters are the most important for early blight severity to create more farm-specific fungicide treatment recommendations. Over...

Early blight in potato, caused by Alternaria solani , is mainly controlled by frequent applications of synthetic fungicides. Reducing the use of synthetic fungicides in agriculture is desired to reach an overall sustainable development since the active components can be harmful for humans and for the ecosystem. In integrated pest management, IPM, the idea is to combine various measures, including optimized crop management, cro...

The choroid plexus is the site of the blood–cerebrospinal fluid (CSF) barrier (BCSFB) and has also been considered as a possible route for peripheral immune signals and cells to transfer to the central nervous system. Infection/inflammation stimulates innate and subsequent adaptive immune responses via Toll-like receptors (TLRs). In this study, we have investigated the mRNA expression of TLRs, cytokines, and tight junction pro...
