To apply a biopesticide based on an entomopathogenic fungus for control of insect pests you have to take in account some factors, especially if it's part of a program of Integrated Pest Management (IPM), which involves many different methods and combinations of products that a priori could incompatible, as the biopesticide based on a fungus with fungicide, or as the insect is not that for which said biopesticide applies. If we apply both products together what would ask the fungicide to the bioinsectide fungus? Definitely a "Are you sure to apply with me?, Sure we are compatible?"

These issues are being dealt between 23 and 25 October at the VIII Congress of the Spanish Society of Applied Entomology (SEEA), asked and answered, of course, in a more profound and scientific way, as a conference of the trends of research about insects to solve problems such as, for example, insect pests in urban and agricultural ecosystems or in animal health. Applied Entomology focused mostly on agriculture and livestock.

Much of the conference program was dedicated to the incidence of insect populations in agricultural crops for improving IPM and reduce the impact of chemical pesticides on the environment. Among the techniques of IPM there's biological control, such as the use of natural enemies to control pest population concentration. The IPM is expecting a boost by government initiatives such as Directive 2009/128/EC that from the 1st January 2014 that will force farmers to have a program of sustainable use of pesticides to reduce the associated risks of the use of pesticides on health and the environment, and the promotion of IPM and use of techniques, alternative or complementary products than conventional pesticides.

As part of this growing interest in IPM, Marta Almazán, head of the Phytopathology, Nematology and Entomology Laboratories of the R&D Department of Futureco Bioscience, presented at this conference to study the compatibility of the entomopathogenic fungus Isaria fumosoroseus strain FE9901, the active ingredient of the bioinsecticide NOFLY, with conventional control products (such as other insecticides and fungicides), and non-target organisms (such as insects and pollinators).

Almazán explained how Futureco Bioscience R&D Department tried, on one hand, the compatibility of the biopesticide with thirty commercial insecticides and seven fungicides using a simulation method of tank mix, and on the other hand, the safety on five natural enemies and two pollinators. The product was compatible with 27% of fungicides and 85% of the insecticides tested and proved not to assume any risk on pollinators. In conclusion, the suitability of incorporating this bioinsectide in IMP proframs, allows its application in conjunction with other control tools that are apparently antagonists.
