“…The variables that differed significantly were grains per pod, pods per plant and productivity. Thus, we confirm the importance of chemical control, within the integrated management of diseases (Garcia et al, 2002;Vieira et al, 2012;Cunha et al, 2014;Souza et al, 2014;Garcia et al, 2016;Tackenberg, et al, 2016).…”

“…However, the occurrence and incidence of diseases stands out as one of the main limiting factors for crop productivity. In the integrated pathogens management, the use of appropriate techniques to place the pesticides in the targeted pathogen is crucial for an effective disease control (Garcia et al, 2002;Souza et al, 2014;Garcia et al 2016).…”

This study aimed to determine the influence of air-assisted and trailing boom technologies on fungicide applications to control diseases incidence and severity on wheat, bean and soybean. The experiments were conducted in three different sites in the Campos Gerais (PR) region in a completely randomized blocks design. In the wheat crop season of 2011, the treatments were: i) control (no fungicide application on the plants); fungicide spray with ii) nozzles in conventional ground boom sprayer; iii) nozzles in trailing boom; and iv) nozzles in conventional boom sprayer + trailing boom simultaneously. In the bean and soybean crop season of 2011-12, we added an extra treatment of boom with airassisted sprayer, since the farmers had this technology available. We conclude that at the area under the disease progress curve (AUDPC), the diseases controlled with fungicides presented lower severity and incidence compared with the control treatment for all the crops evaluated. The fungicide spraying technology aggregated to air-assisted and trailing boom did not differ from the conventional boom sprayer for disease control and yield components of wheat, beans and soybeans.

“…Recentemente, desenvolveu-se adjuvantes naturais baseados em óleos essenciais extraídos da casca de laranjas (Citrus spp. L.), no entanto, há carência de informações sobre sua eficiência (Souza et al, 2014;Coradini et al, 2016;Zampiroli et al, 2019). Diante do exposto o presente trabalho teve como objetivo comparar o produto comercial Valio a base de óleo de laranja com óleo mineral e adjuvante na deposição de gotas de pulverização de produtos químicos nos alvos desejados na aplicação terrestre.…”

O presente trabalho teve como objetivo comparar o produto comercial Valio® a base de óleo de laranja com óleo mineral e adjuvante na deposição de gotas de pulverização de produtos químicos nos alvos desejados na aplicação terrestre. O teste foi realizado em condições de campo, utilizou-se a cultura do feijoeiro comum no municio de Rio Verde, Goiás, na estação experimental MRE Agropesquisa Ltda, localizada nas coordenadas geográficas (17°55'23.68"S e 51° 8'45.32"O). Para a deposição de gotas, foram colocados três coletores de papel hidrossensível distribuídos transversalmente à linha de aplicação ao longo da barra de pulverização. O delineamento foi inteiramente casualizado com quatro repetições, considerando o controle como 0 mL ha-1 de produto comercial na calda. Os papeis hidrossensíveis foram escaneados e analisados com o auxílio do software de análise de deposição de agrotóxicos DepositScan® e depois tabulados no Excel®. Foram definidos o tamanho de gotas, número de gotas, cobertura e volume para todos os tratamentos nas diferentes posições de coleta. O produto comercial Valio® (óleo de laranja) teve um comportamento satisfatório na qualidade da aplicação.

“…Spray adjuvant is used in pesticide applications to alter the physicochemical properties of spray solutions and to increase their effectiveness (Chuah, Tan, & Ismail, 2013). Several studies on the addition of adjuvants to spray solutions have confirmed positive effects of adjuvants on the control of weeds and fungi (Gauvrit, Müller, Milius, & Trouvé, 2007;Souza et al, 2014). These positive effects can be attributed to changes in the physicochemical properties of the spray solution, such as conductivity, viscosity, and surface tension (Sasaki et al, 2015).…”

Using LC–MS/MS, a rapid and sensitive method for the simultaneous determination of pyraclostrobin and azoxystrobin residues in banana matrices (leaf and whole banana) and soil was established. The samples were extracted using acetonitrile and purified through C18 dispersive solid‐phase extraction. The average recovery of the analytes in various matrices was in the range of 77.3%–103.9% with an RSD range of 0.9%–9.5%. The initial deposition amounts of pyraclostrobin and azoxystrobin at 2 h in the banana leaves of the mineral oil group were 1.43 and 1.31 times in Guangxi, and 2.10 and 1.81 times in Hainan for the water group, whereas those in the soil of the water group were 3.45 and 3.03 times in Guangxi, and 2.14 and 3.48 times in Hainan for the mineral oil group. The half‐lives in the leaves and soil of the mineral oil group were not remarkably different from those of the water group. The terminal residue of the analytes on the whole banana was <0.02 mg/kg at 14 days after application from the two sites. The results of this work may indicate and promote the safety of using pyraclostrobin and azoxystrobin in banana production, especially with mineral oil spray adjuvants.
