ABSTRACT: Beef cattle ranching is the main economic activity in the Brazilian Pantanal, undertaken in an extensive manner, mostly in natural environments and dynamic in space and time. The ongoing monitoring, assessment, and performance improvement are key aspects of the search for sustainable use of natural resources in beef cattle ranches, as these ranches are the management units in the Pantanal. In this paper we proposed a data envelopment analysis (DEA) approach to assess the performance of fourteen beef cattle ranches in the Pantanal wetland as a case study, considering financial, productive, and environmental sustainability dimensions. We modeled each dimension separately and calculated an overall performance score. We also fit fractional regression models to study the influence of potential covariates on the performance scores. The methodological approach proposed here proved to be adequate for the case study, as the results are in line with the expectations of decision-makers regarding the performance of the ranches. The overall performance analysis was influenced by the proportion of higher quality native forage resources, which depends on the dynamics and on the spatial-temporal variation of the landscapes. Therefore, overall performance requires adaptive management of ranches based on diversity conservation, which benefits the multifunctionality of products and services. RESUMO: RESUMO: A pecuária de corte é a principal atividade econômica do Pantanal brasileiro, praticada de forma extensiva em ambientes predominantemente naturais e espaço-temporalmente dinâmicos. Monitorar, avaliar e aprimorar continuamente o desempenho das fazendas de pecuária é um aspecto chave na busca do uso sustentável de recursos naturais, já que as fazendas são a unidade de manejo no Pantanal. Nesse sentido, objetivou-se neste artigo a adoção de modelos de análise envoltória de dados (DEA) para avaliar o desempenho de 14 fazendas
pantaneiras como estudo de caso, considerando as dimensões da sustentabilidade financeira, produtiva e ambiental. Cada dimensão foi
modelada separadamente e, na sequência, foi calculado um escore único de desempenho global. Foram ainda ajustados modelos de regressão fracionária para estudar a influência de potenciais covariáveis nos escores de desempenho. A abordagem metodológica aqui proposta mostrou-se adequada ao caso de estudo em questão, com resultados alinhados às expectativas dos tomadores de decisão quanto ao desempenho das fazendas. A análise do desempenho global foi influenciada pela proporção de recursos forrageiros nativos de melhor qualidade, que depende da dinâmica e variação espaço-temporal das paisagens. Portanto, o desempenho global requer uma gestão adaptativa das propriedades com base na conservação da diversidade, o que beneficia a multifuncionalidade de produtos e serviços.

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.
