Fusarium verticillioides is pathogenic to maize and mycotoxin-producer, causing yield losses, feed and food contamination, and risks to human and animal health. Endophytic (ISD04 and IPR45) and epiphytic (CT02 and IM14) bacteria from maize silks were tested in vitro and greenhouse against F. verticillioides and for hydrolytic enzyme production (cellulase, pectinase, protease, lipase, and chitinase). The strains preliminarily identifed as Achromobacter xylosoxidans (ISD04), Pseudomonas aeruginosa (IPR45), and Bacillus velezensis (CT02 and IM14) by 16S gene sequencing. All strains showed antifungal activity in vitro with inhibition values from 58.5 to 100%; they changed hyphae morphology and inhibited the conidial germination by up to 100% (IPR45). The four strains produced at least one enzyme with antifungal activity. The microbiolized seeds reduced the fungal development in stored grains and stalk rot severity in the greenhouse by 72.6% (ISD04). These results highlight the potential of these strains as biocontrol agents against F. verticillioides. |

In crop, livestock and forest integrated system (ICLF) tree thinning management is adopted to add value and minimize competition. This study aims to assess the effect of ICLF and thinning management on eucalyptus growth and wood productivity. The experimental design was in randomized blocks, with four replicates. The treatments were: (I) F, forest with 476 tree ha-1 before and 270 trees ha-1 after thinning (II) CF-S8, with 270 and 135 trees ha-1; (III) ILF-T, with 270 and 101 trees ha-1 (IV) ICLF-S5, with 270 and 90 trees ha-1; (V) ICLFS4, with 270 and 90 trees ha-1 and (VI) ICLF-S8, with 270 and 45 trees ha-1. The ICLF systems increased tree growth and production (clone H13), due to the lower tree density in these systems than homogeneous forest. The total wood production was lower in the integrated systems due to the lower initial tree density than homogeneous forest. The differences observed in the integrated systems are due to the thinning management, such as the season, intensity and type (selection or systematic). The integrated system with the largest number of trees remaining after thinning (ILF-T) presents the highest wood production, equal to 57% of the remaining wood in homogeneous forest. |
