“…8 Therefore, it is critical to develop sustainable management strategies for the control of bacterial wilt diseases, which can be strategically approached by screening resistant seeds, soil fumigation treatment with natural essential oils, chemical control, and microbial control. [9][10][11][12][13][14] Currently, the major strategy is still chemical control, involving applying agricultural bactericides (such as Thiessen copper, Zn thiazole, etc.) or essential oils with antibacterial active ingredients (such as phenols, terpenes, etc.)…”

“…Several studies have reported the effectiveness of hot water treatments against seedborne pathogens (Table 3), and it has been applied successfully applied on a large scale (Koch & Roberts, 2014). Hot water treatments are classical physical methods of plant protection and are reported to reduce the incidence of seedborne fungi, enhance germination and seedling emergence, when conducted under specific conditions with a precise temperature according to each crop and pathogen (Alkemade et al, 2022;Mancini & Romanazzi, 2014). Temperature and the seed immersion time depend on the texture of the seed coat and target pathogen.…”

Seed is a critically important basic input of agriculture, because sowing healthy seeds is essential to food production. Using high quality seed enables less use of synthetic pesticides in the field. Seedborne pathogens can reduce yield quantity and quality of the crops produced. Seed treatments protect plant seedlings from pathogen attacks at emergence and at the early growth stages, contributing to healthy crop plants and good yield. However, there is increased concern about the application of synthetic pesticides to seeds, while alternatives are becoming increasingly addressed in seedborne pathogen research. A series of strategies based on synthetic fungicides, natural compounds, biocontrol agents (BCAs), and physical means has been developed to reduce seed contamination by pathogens. The volume of research on seed treatment has increased considerably in the past decade, along with the search for green technologies to control seedborne diseases. This review focuses on recent research results dealing with protocols that are effective in the management of seedborne pathogens. Moreover, the review illustrated an innovative system for routine seed health testing and need-based cereal seed treatment implemented in Norway. Graphical Abstract

“…Lupin anthracnose, however, is significantly hampering a further increase in lupin cultivation. As no effective sustainable treatment is available yet (Alkemade, Arncken, et al, 2022 ), host resistance would be the most desired solution. Recent studies identified three resistance genes in blue lupin (Fischer et al, 2015 ; Yang et al, 2004 , 2008 ) and one candidate gene and two major quantitative trait loci in white lupin (Alkemade, Nazzicari, et al, 2022 ; Książkiewicz et al, 2017 ).…”

Colletotrichum lupini, the causative agent of lupin anthracnose, affects lupin cultivation worldwide. Understanding its population structure and evolutionary potential is crucial to design successful disease management strategies. The objective of this study was to employ population genetics to investigate the diversity, evolutionary dynamics, and molecular basis of the interaction of this notorious lupin pathogen with its host. A collection of globally representative C. lupini isolates was genotyped through triple digest restriction site‐associated DNA sequencing, resulting in a data set of unparalleled resolution. Phylogenetic and structural analysis could distinguish four independent lineages (I–IV). The strong population structure and high overall standardized index of association (r̅d) indicates that C. lupini reproduces clonally. Different morphologies and virulence patterns on white lupin (Lupinus albus) and Andean lupin (Lupinus mutabilis) were observed between and within clonal lineages. Isolates belonging to lineage II were shown to have a minichromosome that was also partly present in lineage III and IV, but not in lineage I isolates. Variation in the presence of this minichromosome could imply a role in host–pathogen interaction. All four lineages were present in the South American Andes region, which is suggested to be the centre of origin of this species. Only members of lineage II have been found outside South America since the 1990s, indicating it as the current pandemic population. As a seedborne pathogen, C. lupini has mainly spread through infected but symptomless seeds, stressing the importance of phytosanitary measures to prevent future outbreaks of strains that are yet confined to South America.
