Conteúdo: 	The adoption of biocontrol is low in maize production, although it has been reported
reduction in fumonisin levels when combined with fungicides. The objective of this work was
to evaluate the potential of Streptomyces araujoniae (BC1) and Bacillus sp. (BC2) combined
or not with the fungicide azoxystrobin+ciproconazol (FG), on grain yield, Fusarium
verticillioides incidence and fumonisin (B1 and B2) content. Maize plants were sprayed two
times, at V9 and R1 with Water, BC1, BC2, Fungicide alone or in different combinations two
by two. All plants were inoculated with F. verticillioides. Upon harvest, treatments were
evaluated for total yield, F. verticillioides grain contamination (blotter test) and total fumonisin
(B1+B2) contents. FG (V9) + BC1 (R1) resulted in increased yield in three out of four field
trials, while all other treatments increased yield in only two. All treatments except FG (V9 +
R1) reduced F. verticillioides incidence. None of the treatments reduced fumonisin levels, but
FG (V9 + R1), BC1 (V9) + FG (R1) and BC1 (V9) + BC1 (R1) resulted in higher mycotoxin
content compared to the control. FG (V9) + BC1 (R1) increased yield, reduced grain
contamination and didn?t contribute to higher fumonisin levels compared to control.
Therefore, it can contribute to qualitative and quantitative maize grain yield improvement.
