O objetivo do trabalho foi realizar estudos que comprovem a eficácia do tratamento fungicida com epoxiconazole + pyraclostrobin na melhoria da qualidade das sementes de soja. Os experimentos foram instalados em 2003, no Centro Tecnológico do Triângulo e Alto Paranaíba (CTTP/EPAMIG), em Uberaba, MG, e em Sacramento, MG. Em ambos os locais, as unidades experimentais foram constituídas por quatro linhas de 5,0 m, no espaçamento de 0,50m. As pulverizações foram realizadas com pulverizador costal pressurizado. Foram utilizadas seis cultivares de soja (BRSMG 250 [Nobreza], BRSMG 68 [Vencedora], BRSMG 251 [Robusta], MG/BR-46 Conquista, BRSMG Garantia e BRSMG Sublime), combinados com dois tratamentos (1- Testemunha, sem tratamento; 2- Parcelas tratadas com duas aplicações de epoxiconazole + pyraclostrobin, 66,5 + 25,0 g/ha, respectivamente). Os tratamentos foram formados pelo fatorial 6x2 (seis cultivares vs. dois tratamentos fungicidas), totalizando 12. Adotou- se o delineamento em blocos completos ao acaso, com quatro repetições. Nas parcelas que não receberam fungicida houve desfolha provocada pela ferrugem asiática da soja. De maneira geral constatou-se que, entre as cultivares estudadas, aquelas de menor ciclo tiveram vantagens comparativas, tanto em rendimento quanto em qualidade fisiológica de sementes. O fato é observado nos tratamentos com fungicidas, mas foi particularmente nítido nos tratamentos sem fungicidas, em que as menores diferenças entre tratamentos fungicidas foram observadas nas cultivares precoces. Houve diferenças varietais para as variáveis analisadas. Nos tratamentos sem fungicida, ocorrerram redução do ciclo, do rendimento, do peso de 100 sementes e da qualidade fisiológica das sementes.

The use of sensors for livestock monitoring has grown in the last decade, motivated not only by the search for improvements in animal production and health, but also by the better use of physical, fnancial, and human resources in the management of livestock. Since precision livestock farming depends on technological innovation, including the use of sensors, it is essential to validate their applicability in confned animals. Therefore, the objective was to evaluate the functioning of the SCR Heatime® HR System sensor in heifers and analyze the behavioral diferences of these animals in two feedlot systems (tie-stall and loose-housing). Eleven Gyr heifers of 10 months of age and an average body weight of 179±26 kg were used. Animals were equipped with the SCR Heatime® HR System 7 days before the evaluations for adaptation, with the behavioral and system studies carried out during two periods each of 5 days, for 8 h a day. Five heifers were housed in tie-stall bedding and six were housed in loose-housing. After the evaluations for a period, animals have been switched systems in the following period. While the animals had the sensors attached to their bodies, behavioral evaluations were also performed visually, every 3 min by two evaluators per system. Behavior activities were characterized as standing, lying, idle standing, idle lying, ruminating standing, ruminating lying, feed, and water intake. The regression for the rumination activity recorded between the sensor and the visual assessment was signifcant only for loose-housing (P=0.0002), but the Pearson correlation between both was negative and low (r= ?0.25; P=0.0002). The sensor overestimated rumination by 27.3% in loose-housing (28 vs. 22 min/2 h) and 38.5% in tie-stall (36 vs. 26 min/2 h). Thus, when considering the diferent feedlot systems, validation was not possible due to the overestimation of time spent on rumination activity determined by the sensor. In the behavioral comparison between the systems by visual assessment, there was a signifcant diference (P<0.05) for the behaviors of motor activity, idle lying, total idle time, and feed intake between the animals in the two housing systems. As for idle standing, ruminating standing, total rumination time, and water intake, there was no diference (P>0.05). However, the time spent ruminating lying was greater from 10:00 to 12:00 h (43±3 min/2 h) in the tie-stall, whereas in the loose-housing the animals distribute more uniformly their rumination from 08:00 to 16:00 h (26 min/2 h on average). Therefore, the use of the SCR Heatime® HR System sensor is not recommended for Gyr heifers housed in tie-stall and loose-housing systems. Regarding the daytime range of rumination and the accuracy improvements of similar sensors, it is recommended to develop them in both feedlot systems using the periods of less rumination in early morning in tie-stall and late afternoon in loose-housing.
