The use of selective herbicides is important for weed management in agricultural crops. Selectivity studies of new molecules are really important to expand the control options of glyphosate-resistant and -tolerant eudicotyledons in corn. The objective of this work was to evaluate the selectivity of the herbicide saflufenacil applied alone in different doses in post-emergence of corn and in a mixture with glyphosate. The design used was randomized blocks, with four replications, with treatments consisting of five doses of saflufenacil, applied alone and in a mixture with a fixed dose of glyphosate, in addition to the weeded control and only glyphosate. At 7, 14, 21 and 28 days after application (DAT), the phytotoxicity of the herbicides to the crop was evaluated. The physiological variables were measured at 35 DAT. At harvest, yield components were determined, in addition to the mass of 1,000 grains and grain yield. The application of the mixture of glyphosate with saflufenacil increases phytotoxicity symptoms and yield losses. Doses of up to 70 g ha-1, applied alone, caused low phytotoxicity to corn and did not interfere in yield. The use of glyphosate + saflufenacil tank mixtures caused decreases in yield of 43.96 and 40.81% when compared, respectively, with the weeded control and the averages of the applications of the herbicides alone. Saflufenacil has the potential to be used in the management of eudicotyledonous weeds, as long as it is not mixed with glyphosate and the dose limit is respected.

The research investigated the effect of dietary supplementation with Artemia sp. enriched with the autochthonous probiotic Enterococcus faecium on growth performance, microbiota modulation, intestinal morphology, and resistance to pathogenic bacteria of Megaleporinus macrocephalus larvae. The study evaluated four treatments (C: without probiotics; T1: 1 × 104 ; T2:1× 106 ; and T3: 1 × 108 CFU·mL-1) in quadruplicates. The larvae (n = 160; weight = 5.3 ± 2.3mg and length = 3.73±0.4mm) were distributed in 16 L containers at a density of 10 larvae·L-1 for 20 days. The productive performance, survival, gut microbiology, and histology were measured. The larvae were also submitted to acute challenge against the pathogenic bacterium Aeromonas hydrophila. The results showed that supplementation with 1 × 108 CFU·mL-1 promotes greater gain in length (13.78 ± 0.40 cm) and total weight (0.08 ± 0.002 g), higher counts of lactic acid bacteria and lower total heterotrophic in the intestines (7.11±0.30; 0.12 ± 0.09 log CFU·g-1, respectively) and larger villi (0.26 ± 0.03μm). Diets containing probiotics influenced the animals’ resistance to acute infection, with a lower accumulated mortality in T3 (33% ± 11.54%) and a higher one in C+ (93% ± 11.54%). Thus, probiotic supplementation with the autochthonous bacterium E. faecium (1×108CFU·mL-1) provides zootechnical improvement, villus increase and greater resistance to infections.

O estudo avaliou quatro tratamentos (C: sem probióticos; T1: 1 × 104; T2: 1 × 106 ; e T3: 1 × 108 UFC·mL-1) em quadruplicata. As larvas (n = 160; peso = 5,3 ± 2,3 mg e comprimento = 3,73 ± 0,4 mm) foram distribuídas em recipientes de 16 L na densidade de 10 larvas·L-1 por 20 dias. Desempenho produtivo, sobrevivência, microbiologia e histologia intestinal foram medidos. As larvas também foram submetidas a desafio agudo contra a bactéria patogênica Aeromonas hydrophila. Os resultados mostraram que a suplementação com 1 × 108 UFC·mL-1 promoveu maior ganho de comprimento (13,78 ± 0,40 cm) e peso total (0,08 ± 0,002 g), maior contagem de bactérias lácticas e menor de heterotróficos totais nos intestinos (7,11 ± 0,30; 0,12 ± 0,09 log UFC·g-1, respectivamente) e maiores vilosidades (0,26 ± 0,03 μm). As dietas contendo probióticos influenciaram a resistência dos animais à infecção aguda, com menor mortalidade acumulada em T3 (33,33%±11,54%) e maior em C+ (93,33% ± 11,54%). Assim, a suplementação probiótica com a bactéria autóctone E. faecium (1 × 108 UFC·mL-1) proporciona melhora zootécnica, aumento de vilosidades e maior resistência a infecções.
