Abstract

Formulation of biological control agent is an important criterion for sustainable agriculture. Formulation can improve the product stability and viability may result in consistency of field performance of many potential biological control agents. Formulation of biocontrol products has been used against insect pests (bioinsecticides), diseases (biofungicides) and weeds (bioherbicides). Many of the biocontrol agents have been formulated with dried milk, powdered casein, gelatin, saponins, oils, soaps, etc. So far as microbial insecticides are concerned, it is essential that the compound used should not inhibit the successful establishment of the pathogens. Oil based formulation of M. rileyi reduced the pest populations distinctly than other formulations. Ten types of rice bran oil formulations of Metarhizium (Nomuraea) rileyi were prepared by using 5 wetting agents at two different concentrations each. The ten formulations along with an untreated control were evaluated against third in

Conclusion

Development of dry and oil formulations of M. rileyi isolates, combination of different microbial agents and field evaluation against pest complex in crops like groundnut, blackgram and maize. Evaluation of nanomaterial based formulations of M. rileyi against insects. To conduct compatibility studies with novel pesticides under field conditions. To study the efficacy of M. rileyi against insect pests under storage. Development of safety tests data of M. rileyi and documentation, submission for registration as biopesticide.
