Best nematode extraction method for all stage nematode is Correct Answer Cobbs sieving and decanting method

Best nematode extraction method for all-stage nematode is Cobbs sieving and decanting method.
This method is to submerge a plant sample in water in a Petri dish and directly select the nematodes for further identification using the microscope.
This set of 5 stainless steel sieves can be used for extracting nematodes with Cobb's method: decanting and sieving. The high extraction efficiency is obtained using only this small set of sieves and little water. The set contains 5 sieves with a decreasing mesh sizes being 1000 μm, 365 μm, 180 μm, 105 μm and 45 μm.
