“…The compatibility of plant extracts with B. bassiana might be due to inconsistent concentrations of phytoalexins, sulfurade, terpenoids, and triterpenoids compounds (Diepieri et al 2005). The compatibility of EPF with botanicals also depends upon the qualitative and quantitative variations in secondary metabolites composition, which may have a negative impact on the entomopathogenic microorganisms (Ribeiro et al 2012). It is also important that the genetic variability of fungal isolates may also produce varied grades of susceptibility or compatibility to different phytosanitary products (Mohan et al 2007).…”

Wheat aphid, Sitobion avenae (Fab.), is a serious pest of wheat crop across the world. The present study was conducted to evaluate the potentials of the water plant extracts of Azadirachta indica (neem) or Eucalyptus camaldulensis and the entomopathogenic fungi (EPF); Beauveria bassiana or Metarhizium anisopliae against the aphid species. After 5 days of applications, the combined mixture of B. bassiana and eucalyptus extract caused the maximum mortality rate (87%). While the combination of B. bassiana with neem extract showed the least rate (54%). Fecundity was negatively affected by the single and combined treatments of EPF and botanicals extracts. The lowest fecundity (7 nymphs per female) was recorded when the aphid was treated by the binary mixture of B. bassiana and eucalyptus extract. Correspondent maximum fecundity (29 nymphs per female) in 5 days was recorded in control treatment, while 23 nymphs were produced by a single female when treated with the binary mixture of B. bassiana and neem extract. The results indicated that EPF and botanical extracts (neem or eucalyptus) caused significant reduction in survival and fecundity of S. avenae. Therefore, they may be used as promising natural alternatives to synthetic insecticides against the wheat aphid species.

“…Granulosis virus, Spinosad insecticide, and B. thuringiensis were reported to be efficient pest control agents (Aselage and Johnson 2009;Johnson et al 2010). Interactions between biopesticides and entomopathogens such as Beauveria bassiana were also studied for organic production systems (Ribeiro et al 2012), as were strategies such as mass trapping with a mixture of pheromones and pheromone-based mating disruption to control fruit pests (Johnson et al 2010;Arroyo et al 2012). For organic production of onion, the entomopathogens Metarhizium anisopliae, Verticillium lecanii, and Beauveria bassiana and the entomophilic nematode Steinernema carpocapsae considerably reduced the thrips (Thrips tabaci) population, resulting in a higher yield (Visalakshy and Krishnamoorthy 2012).…”

“…as cited in Alves et al 16 . and others 36,37 was used, calculated as

italicBI = \frac{((), 47 * italicVG) + ((), 43 * italicSP) + ((), 10 * italicGER)}{100}

where VG is the percentage of vegetative growth of fungal colony, SP is the percentage of colony sporulation and GER is the percentage of conidia germination relative to the control. The value of BI indicates the level of compatibility where a BI value of 0 to 41 = toxic, 42 to 66 = moderately toxic, and more than 66 = compatible.…”

Background Integrating fungal biocontrol agents into crop protection programs dominated by synthetic pesticides is an important first step towards developing an integrated pest management (IPM) program; however, their successful integration relies on an understanding of how their performance may be impacted by the remaining agrochemicals deployed for managing other pests and diseases. In this study we tested 10 formulated pesticides used in macadamia production at different concentrations to determine their effects on the germination, mycelial growth and sporulation of Metarhizium anisopliae and Beauveria bassiana in vitro. Further tests with laboratory‐grade actives of the noncompatible pesticides were conducted to determine whether any antagonistic effects were caused by the active constituent or by formulation additives. Results At their registered concentrations, formulated trichlorfon, acephate and indoxacarb were compatible with M. anisopliae, whereas B. bassiana showed compatibility with formulated trichlorfon, acephate, indoxacarb, sulfoxaflor and spinetoram. Bioassays using laboratory‐grade active constituents indicated that the adverse impact of formulated beta‐cyfluthrin on both fungal species and that of formulated methidathion on B. bassiana is probably due to components of the emulsifiable concentrate formulations rather than their active constituents. Diazinon was the only insecticidal active that showed high toxicity to both fungal species. The two fungicides, carbendazim and pyraclostrobin, were toxic to both fungal species at all tested concentrations. Conclusion Our results identify which pesticides used on macadamias in Australia are compatible and incompatible with entomopathogenic fungi. Future studies on pesticide degradation rates will help define the spray intervals required to eliminate these adverse effects.
