Dear Maliha Fatima

Measure the diameter of the colony every day after inoculation, calculate the growth rate from one day to another. Or calculate the surface of the colony by the

mathematical formula for Sphere Surface Area = 4 • π • r² = π • d²

and then observe the differences that appear from one day to another.

Growth rate is to be calculated day to day basis and measurement is done as explained nicely by Prof. Kawas

Hello Dear

I apllied some methods for measuring grwoth of Beauveria and Metarhizium in my exoeriments. Please see these methods in my puvlication. I' m be very glad if you see them in my profile. I hope I be helpful for you. Best regards
