“…Intercropping a legume in the rotation with winter wheat reduces the inoculum of Gaeumannomyces graminis (an incidence of foot disease of between 20 and 60% in the third year in this study). Other studies also confirmed the positive effect of rotating wheat with legumes as a pre-crop, observing a reduction in the incidence and severity of the disease in the following year [35]. The higher incidence of foot and root diseases could have been a key factor in this decline in monoculture plots, as other authors also noted [10].…”

In north-western Spain, the cultivation of wheat landraces represents the pillar of quality Galician bread; today, a minimum of 25% Galician flour is required to produce bread under the auspices of the Protected Geographical Indication “Pan Galego”. The main objective of this study was to evaluate the effect of the rotation of two wheat landraces—‘Carral’ and ‘Caaveiro’—with lupin (sweet Lupinus albus), together with a fallow period, on crop yield and quality, as well as the environmental benefits of rotations over conventional monoculture systems. After the different agricultural activities, twelve agronomic parameters were analysed at the end of the third year. For the environmental analysis, the Life Cycle Assessment methodology was applied. The results showed a positive influence of rotation systems on wheat yield and quality parameters, reporting higher specific weight and lower impurities compared to monoculture. No significant differences were observed between wheat rotation and monoculture in other parameters related to baking quality, such as protein, wet gluten, baking strength (W), elasticity (L), tenacity (P), and swelling (G). However, soil quality influenced wheat quality independently of rotation, and higher organic matter and lower phosphorus produced higher W and P, respectively. Moreover, rotation had a positive effect on yield, up to 62% when fallow preceded wheat, and in reducing diseases, pests, and weeds. Finally, in terms of environmental performance, the best results were identified when lupin preceded wheat due to lower fertiliser application. In this regard, the worst profiles corresponded to the scenarios based on monoculture for both wheat landraces.

“…Take-all is a common worldwide root disease of wheat caused by the soil-borne fungus Gaeumannomyces graminis var tritici ( Hernández-Restrepo et al., 2016 ; Gargouri et al., 2020 ). The pathogen has a wide range within the Poaceae family, of which wheat ( Triticum aestivum ), barley ( Hordeum vulgare ), and oats ( Avena sativa ) are the major hosts.…”

“…Take-all infection begins with root rot and later spreads to the crown and interrupts the water transport into plants. The aerial symptoms include stunted plants, premature ripening, and whiteheads which can be confused with other soil-borne diseases like fusarium foot rot ( Cook, 2003 ; Kwak and Weller, 2013 ; Gargouri et al., 2020 ). The disease can develop at a soil pH of 5.5 to 8.5, and the optimum temperature for its growth is 20-25°C.…”

Wheat is a crop of historical significance, as it marks the turning point of human civilization 10,000 years ago with its domestication. Due to the rapid increase in population, wheat production needs to be increased by 50% by 2050 and this growth will be mainly based on yield increases, as there is strong competition for scarce productive arable land from other sectors. This increasing demand can be further achieved using sustainable approaches including integrated disease pest management, adaption to warmer climates, less use of water resources and increased frequency of abiotic stress tolerances. Out of 200 diseases of wheat, 50 cause economic losses and are widely distributed. Each year, about 20% of wheat is lost due to diseases. Some major wheat diseases are rusts, smut, tan spot, spot blotch, fusarium head blight, common root rot, septoria blotch, powdery mildew, blast, and several viral, nematode, and bacterial diseases. These diseases badly impact the yield and cause mortality of the plants. This review focuses on important diseases of the wheat present in the United States, with comprehensive information of causal organism, economic damage, symptoms and host range, favorable conditions, and disease management strategies. Furthermore, major genetic and breeding efforts to control and manage these diseases are discussed. A detailed description of all the QTLs, genes reported and cloned for these diseases are provided in this review. This study will be of utmost importance to wheat breeding programs throughout the world to breed for resistance under changing environmental conditions.

“…In particular, the density of host crop species can be a crucial factor in recruiting and multiplying crop-specific pathogens (Zhu et al, 2000;Hiddink et al, 2010), with monocultures tending to accumulate specific pathogens in soils, as compared to more diverse plant communities where the presence of such pathogens becomes diluted (Zhu et al, 2000;Hiddink et al, 2010;Boudreau, 2013;Ampt et al, 2018;Mommer et al, 2018). For instance, monocultures of wheat, maize and soybean have been shown to accumulate high abundances of soilborne fungal pathogens specialized in attacking each crop, such as Gaeumannomyces graminis in wheat (Ramanauskienė et al, 2018;Gargouri et al, 2020), Stenocarpella maydis in maize (Flett & Wehner, 1991;Pinto et al, 2022), and Macrophomina phaseolina in soybean (Pérez-Brandán et al, 2014). On the other hand, the intensive use of fungicides (Price et al, 2015;Ons et al, 2020;Mu et al, 2022), as well as other management practices associated with the main crops in the area (Li et al, 2018;Wang et al, 2019;Chen et al, 2019b;Liu et al, 2019;Sun et al, 2020), could have effects on the regional soil-borne 1 3…”
