Figure 3:
(A) This inset image shows a re-sealable plastic bag containing a thin sponge. This is how nematodes are stored and shipped prior to inoculation in a spray solution.

(B) This image shows the now empty bag and a 20 litre bucket with the sponge in it. This bucket was filled to 20 litre to form a starter solution which was then added to the 180 litre of water in the 200 litre tank.

(C) This image show Jennifer Llewellyn looking through a microscope and counting the nematodes suspended in 1 millilitre of spray solution sampled form the spray tank.

(D) This inset image shows the view of undiluted nematodes on a microscope slide, as photographed through the microscope ocular.
