Table 2 Description of the eligibility criteria: population, climate, language, intervention, outcome and study type(s) in the screening process
Eligible criteria | Included | Excluded |
|---|---|---|
Population | Studies on oilseed rape crops (Brassica napus) conducted in the field | Studies not including B. napus or including oilseed rape (B. napus) but performed in laboratories or greenhouses, as pot experiments or based on GMO cultivars or lineages |
Climate | This inclusion criterion was based on the Köppen-Geiger climate classification [27]. Studies from temperate regions in zones Cfb and Dfb, corresponding to the main agricultural areas of southern Sweden, and Dfc, corresponding to northern Sweden. Studies from regions in the climate zone Cfa since this climate is expected to prevail in Sweden due to climate change | Studies conducted in a geographical region with no relevant climate based on the Köppen-Geiger climate classification zones |
Language | Full text in English, Swedish, Norwegian or Danish | Any study not available with its full text in one of the relevant languages |
Interventiona | Any disease management intervention, independently or in combination, including but not limited to crop rotation, resistant cultivars, cultivar mixtures, ploughs, no-tillage, biological control, and biofungicide and pesticide applications | Studies that applied pesticide active substances not allowed for use against plant diseases in the EU. For this purpose, a list of active substances allowed for use in the EU was retrieved from the European Commission database (https://ec.europa.eu/food/plant/pesticides) at the start of the article screening process (Additional file 3) |
Outcome | Any type of effect of disease control interventions measured by productivity in terms of total harvest, the yield per unit area or relevant crop quality measures, e.g., plant health status or reduced disease symptoms. Disease reduction was included as a proxy for a potential yield increase or an increase in crop quality | |
Study design | Use of any relevant experimental study design including but not limited to before and after (BA) studies, randomized control trials (RCTs) randomized split block trials (RSBTs) and exposure versus no exposures/control impact (CI) | Articles and reports not including original data and/or with no relevant study design or experimental data not statistically evaluated |
