“…Thus there is an additional degree of uncertainty about mycotoxin risk above that of projected FHB risk. Inoculum pressure and composition will correlatively but differentially affect these two risks and be driven not only by weather and climate change, but also by competition with other pathogens (Xu et al 2007a, b), fungicide applications (Pirgozliev et al 2002), and cropping practices (Brennan et al 2007;Landschoot et al 2013;Leoni et al 2013). The latter may be influenced by markets and policy that may or may not be affected by climate change.…”

Methods used to assess climate change risk for crop diseases often assume that both host and pathogen are present. Consequently, model output may misrepresent future growing seasons, due to a failure to reflect likely change at the landscape-and farm-scale and its impact on disease risk. In this study, data defining the spatial coverage of crops in Scotland were combined with spatially coherent, probabilistic climate change data to project the future risk of Fusarium head blight (FHB) in wheat. Primary inoculum was initially treated as non-limiting, and a widely accepted crop-diseaseclimate model for FHB risk assessment was used to project the risk of disease occurrence in over 50,000 crop locations. Primary inoculum was then treated as limiting, and an atmospheric dispersion model was used to modify projections according to the risk of inoculum dispersal from overwintering refugia to crop locations. In both cases it was predicted that FHB hazard will decrease in Scotland over time. Consequences for the species composition of the FHB complex and therefore the associated mycotoxin hazard were considered. To guide adaptation strategies, we also considered agronomic scenarios regarding potential climate-changedriven shifts in agricultural practices and planting patterns, and their effects on disease risk. We found that opportunities exist for increased cultivation of crops that are potent sources of Fusarium or Gibberella inoculum, and for movement of crops away from coastal areas vulnerable to sea-level rise, with little additional risk of FHB. These projections, made by considering the temporal and spatial coincidence of host and pathogen species under various climate change scenarios, suggest that improved control of FHB might not be a high priority for future food security in Scotland.

“…Crop rotations are generally longer and spatial diversity is greater under organic compared with conventional management . Crop sequences are adjusted to optimize nutrient availability and minimize the risk of weeds, diseases and pests . Increased habitat diversity is also used to enhance natural pest and disease control, among others by intercropping and planting of trees, shrubs, wild grasses and flowering plants (Table ) .…”

“…It may also include winter cover crops for nitrogen fixation or a reduction in nitrate leaching . The choice of the cover crop is important to reduce the chance of disease outbreaks and nematode damage in the following cash crop . Cover crop mixtures usually perform better than single species owing to optimal niche utilization and reduced spread of diseases and pests .…”

Organic farming (OF) has significantly increased in importance in recent decades. Disease management in OF is largely based on the maintenance of biological diversity and soil health by balanced crop rotations, including nitrogen-fixing and cover crops, intercrops, additions of manure and compost and reductions in soil tillage. Most soil-borne diseases are naturally suppressed, while foliar diseases can sometimes be problematic. Only when a severe disease outbreak is expected are pesticides used that are approved for OF. A detailed overview is given of cultural and biological control measures. Attention is also given to regulated pesticides. We conclude that a systems approach to disease management is required, and that interdisciplinary research is needed to solve lingering disease problems, especially for OF in the tropics. Some of the organic regulations are in need of revision in close collaboration with various stakeholders.

“…Application of compost or a mixture of compost and manure are generally more effective than crop residues (Bonanomi et al, 2007;Senechkin et al, 2014;Serra-Wittling et al, 1996). However, the effect of plant residues on populations of F. oxysporum depends very much on the particular crop providing the residues (Leoni et al, 2013). Moreover, the effects of amendments such as composts are not always the same for different plant pathosystems (Bonanomi et al, 2010;Termorshuizen et al, 2006).…”
