The garlic I planted in my garden last year was infected by white rot (Sclerotium cepivorum).
I'd like to inspect how much of the white rot sclerotia is present in the soil. I've googled and found that determination of sclerotia is mainly done by many rounds of wet sieving and manually counting dull black sphere looking particles through a microscope, picking them up and placing in water agar for 2 weeks
The article is 40 years old, so I am wondering if determination method is still the same. As someone who never never determined any fungi sclerotium before, so I'd love to hear additional info and guidance on how to handle it. What sieving tools are best suitable (I imagine sieving is not done manually)? What is the preferred size of petri dishes and so on.. Even a general description of the whole process is more than welcome.
