Resumo: | The objective of this research was to analyze, under laboratorial conditions, the compatibility between the entomopathogenic fungi Metarhizium anisopliae and fungicides recommended to bean crop (Phaseolus vulgaris L.). The pesticides analyzed were Manzate WG® (a.i. mancozeb) (500 g × 100 L-1), Nativo® (a.i. tebuconazole + trifloxystrobin) (300 mL × 100 L-1), Portero® (i.a. carbendazim) (250 mL × 100 L-1) and Tebuco Nortox (i.a. tebuconazole) (250 mL × 100 L1). The toxic effect of fungicides on the entomopathogen was performed in laboratorial conditions by the addition of the pesticides in culture medium BDA. After medium solidification were inoculated the reproductive structures of entomopathogen, at 107 conidia/mL, totaling eight replicates per treatment. After 24 h the conidia viability was analyzed, and after seven days , the area of colony growth (cm2) was measured and the number of conidia for each treatment was counted, being the media compared by Tukey test (P < 0.05), and standardized by compatibility classification. All fungicides inhibited the vegetative growth and conidiogenesis of M. anisopliae. Only the active ingredient mancozeb provided conidia viability of M. anisopliae, represented by 7.25 ± 1.11% of viable conidia. All tested fungicides were toxic to the entomopathogenic fungi M. anisopliae, under laboratorial conditions. |

Os agrotóxicos analisados foram Manzate WG® (i.a. mancozebe) (500 g × 100 L-1), Nativo® (i.a. tebuconazol + trifloxistrobina) (300 mL × 100 L-1), Portero® (i.a. carbendazim) (250 mL × 100 L-1) e Tebuco Nortox (i.a. tebuconazol) (250 mL × 100 L1). O efeito tóxico dos fungicidas sobre o entomopatógeno foi determinado em condição laboratorial, através da adição dos produtos químicos em meio de cultura BDA. Após solidificação do meio, foram inoculadas as estruturas reprodutivas do entomopatógeno, na concentração de 107 conídios/mL, totalizando oito repetições por tratamento. A viabilidade dos conídios foi analisada 24 h após inoculação, e após sete dias foi mensurada a área de crescimento da colônia (cm2), e contabilizado o número de conídios em cada tratamento, sendo as médias comparadas pelo teste de Tukey (P < 0,05), e padronizadas pela classificação de compatibilidade. Todos os fungicidas inibiram por completo o crescimento vegetativo e a conidiogênese de M. anisopliae. Apenas o ingrediente ativo mancozebe propiciou a viabilidade de conídios de M. anisopliae, representado por 7,25 ± 1,11% de conídios viáveis. Todos os fungicidas testados são tóxicos ao fungo entomopatogênico M. anisopliae, sob condição laboratorial.Revista Brasileira Multidisciplinar - ReBraM2020-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistarebram.com/index.php/revistauniara/article/view/74310.25061/2527-2675/ReBraM/2020.v23i2.743Revista Brasileira Multidisciplinar - ReBraM; v. 23 n. 2 (2020): Maio-Agosto; 180-1872527-26751415-3580reponame:Revista Brasileira Multidisciplinarinstname:Universidade de Araraquara (UNIARA)instacron:UNIARAporhttp://revistarebram.com/index.php/revistauniara/article/view/743/601Copyright (c) 2020 Revista Brasileira Multidisciplinarinfo:eu-repo/semantics/openAccessLópez Espinosa, David JossueAparecida Cunha, NatáliaIsla Rivera, SilviaFlores Ricardez, Alejandro GregorioNunes Carvalho, ValdeirBatista da Silva, AleskaTeixeira Duarte, Rogério2020-10-05T03:34:04Zoai:ojs.revistarebram.com:article/743Revistahttp://revistarebram.com/index.php/revistauniaraPRIhttps://revistarebram.com/index.php/revistauniara/oairevistauniara@uniara.com||2527-26752527-2675opendoar:2020-10-05T03:34:04Revista Brasileira Multidisciplinar - Universidade de Araraquara (UNIARA)false |
