Compatibility of Beauveria bassiana and alternative phytosanitary products

“…). A similar study using the extracts of cedar plant, Toona cilliata M. Roemer (Meliaceae) and neem oil, mixed with the fungus B. bassiana before application did not interfere with the pathogenicity of the fungus on Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae) (Ferreira ).…”

“…The index considers the production of conidia as a more important factor than vegetative growth, since they are the propagules of the fungus that will act in the development of the disease in the insect (Moino and Alves 1998). There are studies in the literature that evaluate the toxicity of the products, using the equation model proposed by Alves et al (1998b) (Cavalcanti et al 2002;de Oliveira et al 2003;Santos et al 2009;Mertz et al 2010;Ferreira 2011), and works evaluating the Biological Index proposed by Rossi-Zalaf et al (2008) (Pires et al 2010;Ferreira 2011;Mamprim et al 2013).…”

“…Although several studies have already been carried out on the compatibility of alternative products and entomopathogenic fungi, new natural products appear on the market every year; thus, compatibility tests become necessary for the success of these control agents. With this objective, studies were carried out to evaluate the compatibility of entomopathogenic fungi with aqueous extract of seeds and neem leaves (Depieri et al 2005;Zorzetti et al 2012;Mamprim et al 2013;Togb e et al 2014), neem oil (Marques et al 2004;Araujo et al 2009), extracts of meliaceae (Ferreira 2011) and alternative commercial products (Mertz et al 2010;Mamprim et al 2013Mamprim et al , 2014.…”
