Yield losses of cereal crops by Fusarium Link: A review on the perspective of biological control practices

Abstract

Fusarium wilt caused by 58 species is one of the most common fungal diseases causing both quantitative and qualitative losses in all cereal regions around the world. Thus, F. graminearum is the most dominant species on wheat and barley, F. verticilloides on maize, F. fujikiroi on rice and F. thapsinum on sorghum. The use of biological methods seems promising because of their high efficiency in terms of economy, ecology, and disease control. In addition, the key to successful biocontrol is to choose a strong biocontrol agent first. However, the main objective of the work is to make a bibliographical synthesis to facilitate the choice of various practice to control of Fusarium wilt. A complete study was carried out on 180 published literatures during the period 2000–2021, of which 30% were published from 2000–2011 and 70% from 2012–2021. Among 55 genera, strains of genus Trichoderma, Bacillus, Pseudomonas, Streptomyces reduced Fusarium wilt on average by 72.97, 51, 51.77 and 33.36% in greenhouse tests and 56.82, 42.83, 51.51 and 34.91% in the field, respectively. C. rosea, T. harzianum, P. fluorescens and B. subtilis reduced Fusarium on average by 70.33, 74.16, 51.77 and 49.95% in greenhouse tests and 62.55, 48.72, 56.62 and 49.3C%o in the field, respectively. In conclusion, this literature review gathers promising biocontrol agents to control Fusarium species in cereals. Finally, we point out that it would be necessary to take into account the number of repeated uses of biocontrol agents during the cereal production cycle, which is lacking in the literature.
