In addition to its effects on grain yield, the infection can be detrimental to grain quality (Czembor et al.

andiyazi) belonging to the Fusarium fujikuroi species complex (FFSC) is responsible for stalk and ear rot of maize, a current problem of maize in northern Sinaloa, Mexico (Leyva-Madrigal et al. A consortium of four different Fusarium species ( Fv, F. Maize monoculture has provoked a high incidence of the disease as well as crop losses due to Fv, in Mexico’s Sinaloa state (Quintero-Benítez and Apodaca-Sánchez 2008). is the most commonly reported fungal species infecting maize, causing stalk, ear and root rot (SERR) of maize, and is responsible for important economic losses worldwide (Hernández-Rodríguez et al. Fusarium verticillioides ( Fv) (Sacc.) Nirenb. Maize is an important crop in Mexico due to cultural consumption habits and economic profitability. Maize ( Zea mays L.) is one of the most important cereals grown worldwide. Antagonistic activity analysis revealed that these strains produce glucanases, proteases or chitinases, as well as siderophores and auxins and suggests these as possible control mechanisms against Fv.

Pot experiments performed in a greenhouse with Bacillus cereus sensu lato B25 confirmed these findings and showed a reduction of Fv disease severity and incidence on plants. ( B35) displayed the highest antagonistic activity against Fv. cereus sensu lato ( B25) and Bacillus sp. In planta assays demonstrated that three Bacillus isolates: B. The complete collection was screened for potential activity against Fv using a liquid antagonism assay followed by dual cultures in solid medium, selecting for 42 bacteria ( Bacillus, Pseudomonas and Paenibacillus) that inhibit Fv growth (>45 %). A culturable bacterial collection consisting of 11,520 isolates enriched in Firmicutes and Proteobacteria was created from rhizosphere samples taken from SERR symptomatic or asymptomatic maize plants. The aim of the present work was to screen bacterial isolates in order to find novel native biocontrol agents against Fv. The stalk, ear and root rot (SERR) of maize caused by Fusarium verticillioides ( Fv) severely impacts crop production in tropical and subtropical regions.
