“…However, worldwide there are currently only four computer simulation studies available that project an altered risk of diseases in maize based on a modelling approach that is linked to a climate change scenario; two of these address Brazil (Ferreira & Miranda, 2020; Moraes et al, 2011), one addresses the Philippines (Salvacion et al, 2015), and one the entire globe (Ramirez‐Cabral et al, 2017). Fortunately, the latter simulation study also considers Europe.…”

Maize productivity is threatened by global climate change. Climate change scenarios suggest that north‐western (NW) Europe will get warmer and drier during the main crop‐growing period. In general, more northerly regions will benefit, whereas more southerly regions will suffer suboptimal rain‐fed farming conditions. In these latter regions in particular, the resulting probable lower realized on‐farm maize grain and biomass yields must be safeguarded. Breeding for resistance against already existing and emerging diseases and insect pests is one component to achieve yield stability across years. Durable multiple‐disease resistance will become especially crucial. Herein, we focus on disease resistance breeding approaches in maize, especially related to northern corn leaf blight and Fusarium ear rots, although virus and bacterial diseases will become more important as well. Continuous adjustments of disease resistance breeding strategies will be required. Insect pest resistance breeding must be improved considerably, as in a warmer world insects will thrive, probably causing detrimental direct (feeding, sucking, etc.) and indirect (vectors of pathogens, feeding wounds creating gateways for many pathogens, passive transport of inoculum across maize plants) effects. Four case studies on insects that are already prevalent in NW Europe or may be expected in the near future are covered in this review. Maize cultivars need to combine both durable multiple‐disease and multiple‐insect resistance, although the implementation of many different effective resistance resources in breeding programmes will be challenging, particularly if trade‐offs among breeding goals appear.

“…The climatic risk for the occurrence of plant diseases has been studied for several pathosystems, such as common corn rust (Ferreira and Miranda 2020) Air temperature, relative humidity, and rainfall are the main environmental drivers for determining the risks for plant diseases (Aparecido and Rolim 2020; Beruski et al 2019). However, these factors present a high seasonal and interannual variability, imposing different risk levels for diseases occurrence.…”

Air temperature and relative humidity are the main drivers of many fungal diseases, such as moniliasis (Moniliophthora roreri), which affects cocoa production worldwide. This disease occurs in some Latin American countries; however, it has not yet occurred in Brazil. Moniliasis could cause serious damage to the Brazilian cocoa production if present in the country. Therefore, to know the risks of moniliasis to cocoa production in the largest Brazilian producing region, in the state of Bahia, this study investigated the climatic favorability for the occurrence of this disease in this state, by defining and mapping the climatic risks and by assessing the influence of El Niño Southern Oscillation (ENSO) phases on it. Daily air temperature and relative humidity data from 28 weather stations of the national weather network in the state of Bahia, between 1988 and 2018, were employed to determine the risk index for cocoa moniliasis occurrence (RICM), based on the number of days favorable to the disease, which was categorized in five levels of favorability, ranging from “unfavorable” to “very favorable”. Seasonal and annual RICM maps were generated by a multiple linear regression procedure, considering raster layers of latitude, longitude, and altitude. The maps showed a high spatial and temporal RICM variability in the state of Bahia, with the highest risk for moniliasis occurrence in the eastern part of the state, where most producing areas are located. The ENSO phase showed to influence cocoa moniliasis occurrence, with the years with a transition between El Niño and Neutral phases being the most critical for this disease in majority of assessed locations. These results show that cocoa producers in the state of Bahia, Brazil, should be concerned with moniliasis occurrence as a potential disease for their crops, mainly in the traditional producing regions and when ENOS is in a transition from El Niño to Neutral.
