Materials required


    Metarhizium anisopliae
  • Coconut water
  • Flat glass bottles
  • Cotton plug
  • Pressure cooker
  • Injection syringe
  • Bunsen burner
  • Laminar flow chamber
  • Mixer grinder

Methodology

Metarhizium anisopliae

Take glass bottles containing 40 ml of coconut water. Plug these bottles with cotton plug and sterilize in autoclave for 20 minutes at 15 psi. The bottles are inoculated with 1 ml suspension containing spores of the fungus with the help of a sterile injection syringe. Sterilize the bottles with the help of burner. Spores are inoculated in bottles with the help of syringe in a laminar flow chamber. Keep inoculated bottles till the surface of medium is fully covered by the olive green sporulated fungus. Whole culture is grinded thoroughly in mixer. Keep culture in cool and dry place in packets.

In Carrot broth

Material Required
