Summary

O objetivo deste estudo foi avaliar o efeito in vitro dos produtos comerciais Dalneem®, Ecolife® e Stubble Aid® na concentração rotulada (CR), na metade (½CR) e no dobro dessa concentração (2CR) e dos extratos aquosos de raiz de Curcuma longa (Zingiberaceae) e de folhas de Cymbopogon citratus (Poaceae), Corymbia citriodora (Myrtaceae) e Rosmarinus officinalis (Lamiaceae), na concentração de 10% (p/v) sobre Metarhizium anisopliae. Os tratamentos foram pulverizados sobre o fungo previamente inoculado no meio de cultura BDA (batata, dextrose e ágar), em placas de Petri. Foram avaliadas as unidades formadoras de colônias (UFC), crescimento vegetativo, produção de conídios, germinação de conídios e atividade inseticida sobre lagartas de Diatraea saccharalis (Lepidoptera: Crambidae). Apesar dos produtos comerciais terem afetado significativamente alguns parâmetros biológicos do fungo, somente Dalneem® 2CR foi classificado como incompatível com o fungo. Os extratos vegetais ocasionaram efeito significativo somente sobre o crescimento vegetativo do fungo (variando de 4 a 7%), sendo todos classificados como compatíveis com o isolado de M. anisopliae.


Summary translation

This study aimed to evaluate in vitro effect of commercial products Dalneem®, Ecolife® and Stubble- Aid® in recommended concentration of the product (RC), half that concentration (½RC) and twice that concentration (2RC) and the aqueous rhizomes extracts of Curcuma longa (Zingiberaceae), aqueous leaves extracts of Cymbopogon citratus (Poaceae), Corymbia citriodora (Myrtaceae) and Rosmarinus officinalis (Lamiaceae) in 10% concentration (w/v) on Metarhizium anisopliae. The treatments were sprayed onto the fungus previously grown in Petri dishes with PDA (potato, dextrose and agar) culture medium. There were analyzed the colony forming units (CFU), vegetative growth, conidial production, conidial germination and insecticidal activity against Diatraea saccharalis larvae (Lepidoptera: Crambidae). Although commercial products significantly affected some biological parameters of the fungus, only Dalneem® 2RC was classified as incompatible with the fungus. The plant extracts caused significant effect only to vegetative growth (ranging from 4 to 7%), and were all classified as being compatible with the strain of M. anisopliae.
