Fusarium head blight (FHB), caused mainly by Fusarium graminearum, is best controlled with demethylation inhibitor (DMI) fungicides during flowering. However, the use of premixes of DMI and quinone outside inhibitor (QoI) fungicides to control FHB has increased in Brazil. Data on FHB severity and wheat yields measured in field experiments conducted in Brazil were gathered from both peer- and non-peer-reviewed sources published from 2000 to 2018. After applying selection criteria, 73 field trials from 35 bibliographic sources were identified, among which 50% of the data were obtained from cooperative network trials conducted after 2011. To be included in the analysis, a DMI+QoI premixes or tebuconazole (TEB) were tested in at least 14 trials and three years. Four premixes met the criteria. Estimates of percent control (and respective 95% confidence interval) by a network model fitted to the log of the treatment means ranged from 44.1% (pyraclostrobin + metconazole applied once; 32.4 to 53.7) to 64.3% (pyraclostrobin + metconazole; 58.4 to 69.3); the latter not differing from TEB (59.9%, 53.6 to 65.3). Yield response was statistically similar for pyraclostrobin + metconazole (532.1 kg/ha, 441 to 623) and trifloxystrobin + prothioconazole (494.9 kg/ha, 385 to 551), and both differed statistically from a group composed of TEB (448.2 kg/ha, 342 to 554), trifloxystrobin + TEB (468.2 kg/ha, 385 to 551), azoxystrobin + TEB (462.4 kg/ha, 366 to 558) and pyraclostrobin + metconazole applied once (413.7 kg/ha, 308 to 518). The two categories of FHB index (7% cut off) and yield (3,000 kg/ha cut off), both in the non-treated check, did not explain the heterogeneity in the estimates. Two sequential sprays of TEB or one spray of pyraclostrobin + metconazole as management choices are likely more profitable than DIM+QoI premixes sprayed twice during flowering considering only the fungicide effects on yield.

ABSTRACT - The objective of this work was to evaluate the effect of different water salinity levels on the growth performance, survival, and masculinization rate of Nile tilapia (Oreochromis niloticus) larvae in a biofloc technology (BFT) system. Seven salinity levels (0, 2, 4, 6, 8, 10, and 12 g L-¹) were tested during four weeks in the masculinization period after the absorption of the yolk sac in a matured biofloc system. The water quality variables were within the recommended range for Nile tilapia farming. However, the nitrite peaks were higher at higher salinity levels and were associated with the lower survival of fish at salinity levels equal to or higher than 6 g L-¹. There was no difference between treatments for average final body weight and masculinization rate. Final biomass and survival decreased, and the feed offered as a proportion of final biomass showed the worst results because of the increase in salinity. Therefore, since higher masculinization rates are not obtained at slight and moderate levels of saline water, salinity should be kept close to 0 g L-¹ for the masculinization protocol of Nile tilapia in a BFT, for a better survival and higher biomass of the fish, as well as a lower waste of the offered feed. RESUMO - O objetivo deste trabalho foi avaliar o efeito de diferentes níveis de salinidade da água sobre o desempenho de crescimento, a sobrevivência e a taxa de masculinização de larvas de tilápia-do-nilo (Oreochromis niloticus) em sistema de tecnologia de bioflocos (BFT). Sete níveis de salinidade (0, 2, 4, 6, 8, 10 e 12 g L-¹) foram testados durante quatro semanas no período de masculinização após a absorção do saco vitelino, em sistema de bioflocos maturados. As variáveis de qualidade da água estiveram dentro dos intervalos recomendados para a produção de tilápia-do-nilo. Entretanto, os picos de nitrito foram mais altos nos tratamentos com maiores níveis de salinidade e foram associados à menor sobrevivência dos peixes em salinidade igual ou superior a 6 g L-¹. Não houve diferença entre os tratamentos quanto ao peso médio final e à taxa de masculinização. A biomassa final e a sobrevivência diminuíram, e o alimento oferecido como proporção da biomassa final apresentou os piores resultados em razão do aumento da salinidade. Portanto, uma vez que não são obtidas taxas de masculinização maiores em água leve ou moderadamente salinizada, a salinidade deve ser mantida próxima de 0 g L-¹ para o protocolo de masculinização de larvas de tilápia-do-nilo em BFT, para melhor sobrevivência e maior biomassa dos peixes, assim como menor desperdício do alimento oferecido.
