Are camouflaged seeds less attacked by wild birds? Scientia Agricola
Almeida,Alexandre de; Couto,Hilton Thadeu Zarate do; Almeida,Álvaro Fernando de.
Wheat, corn and rice crops in Brazil use seeds treated with systemic insecticide/nematicide carbofuran, mixed to rhodamine B red dye. Carbofuran is toxic and rhodamine B is attractive to wild birds that eat up these seeds, resulting in notable mortality during planting. A field experiment was performed in southeast Brazil to evaluate if camouflaged seeds would be less consumed by wild birds in comparison to commercial seeds with red-colored rhodamine B and aposematic blue seeds. Camouflaged seeds were less removed than seeds with rhodamine B and natural colors. The camouflaging was more effective in the presence of irregularities and litter. There was no removal of blue-colored seeds. As legislation requires treated seeds to receive a different color to...

Camouflaging of seeds treated with pesticides mitigates the mortality of wild birds in wheat and rice crops Scientia Agricola
Almeida,Alexandre de; Couto,Hilton Thadeu Zarate do; Almeida,Álvaro Fernando de.
Seeds used to plant wheat, corn and rice crops in Brazil are treated with the insecticide carbofuran associated with the dye rhodamine B, attracting granivorous birds and causing mortality during sowing. The objective of this study was to evaluate if using camouflaged seeds can minimize mortality caused by the ingestion of seeds with carbofuran. Alternatives for reducing mortality, such as using carbofuran without rhodamine B or replacing carbofuran by carbosulfan, were compared. Three experiments were carried out in regions of known bird mortality in the states of Paraná and São Paulo, Brazil, using conventional sowing over plowed soil in the traditional planting system, 15,896 kg of seeds in 111.46 ha. Bird carcasses were collected and dissected to...

Efeitos de tratamentos diferenciados no plantio de banana var. Prata-Anã através da quantificação de resíduos de carbofuran Rev. Bras. Frutic.
Castro,Izabela Miranda de; Rodrigues,Maria Geralda Vilela; Godoy,Ronoel Luiz de Oliveira; Quinteiro,Leila Martins da Costa; Carvalho,Lucia Maria Jaeger de.
Este trabalho teve como objetivo avaliar os níveis de resíduos de carbofuran utilizando métodos específicos de análise em amostras de bananas Musa spp submetidas a nove tratamentos distintos de controle químico. As aplicações do produto na plantação foram realizadas durante o cultivo segundo as Boas Práticas Agrícolas (BPA), evidenciando-se os seus efeitos nas concentrações de resíduos. Em seis destes tratamentos, efetuou-se a aplicação de 80g/planta do produto comercial diretamente no solo, de acordo com a recomendação do fabricante, e nos outros três tratamentos restantes, foram feitas aplicações com uma quantidade aproximadamente seis vezes menor (12g/planta) na muda desbastada. Após a colheita, os frutos foram analisados casca e polpa separadamente por...

Evaluation of biomarkers in oyster larvae in natural and polluted conditions ArchiMer
Damiens, Gautier; His, Edouard; Gnassia Barelli, Mauricette; Quiniou, Francoise; Romeo, Michèle.
Crassostrea gigas D-shaped larvae were subjected to different conditions of temperature and salinity for 24 h and four biomarkers (acetylcholinesterase (AChE) activity, thiobarbituric acid reactive substances (TBARS) levels, glutathione S-transferase (GST) and catalase (CAT) activities) were measured. AChE activity decreased when salinity increased from 25 to 30 and 35 psu at 20 and 25 degreesC. Temperature did not seem to have an influence on AChE activity. TBARS levels increased as a function of salinity when the temperature was maintained at 20 degreesC, whereas at 25 degreesC no effect of salinity could be observed. Variations in GST and CAT activities were not significant with salinity and temperature except that catalase activity was higher at 25...

Qualidade fisiológica de sementes de milho tratadas associadas a polímeros durante o armazenamento Ciência e Agrotecnologia
Pereira,Carlos Eduardo; Oliveira,João Almir; Evangelista,José Renato Emiliorelli.
O uso de produtos fitossanitários aplicados via sementes é uma prática rotineira para a cultura do milho. No entanto, a crescente preocupação com o meio ambiente e com a segurança humana torna necessário o desenvolvimento de tecnologias que venham reduzir os riscos com a manipulação destes fitoprotetores, sendo este um dos principais objetivos do uso de polímeros. Assim, com este trabalho, objetivou-se avaliar a qualidade fisiológica e sanitária de sementes de milho submetidas a tratamentos fitossanitários em associação com diferentes polímeros, durante o armazenamento. Para tanto, as sementes de milho dos híbridos AG9010 e AG122 foram tratadas ou não com inseticida carbofuran (nome comercial: Furazin) na dosagem de 1,5 L/100 kg de sementes e em mistura...
