The tulu, a popular ornamental plant, does not reproduce naturally, and is only bred and sold by specialized horticultural companies. Unfortunately, the tulu is easily devastated by a contagious fungal rot. The govt ministry plans to reassure worried gardeners by requiring all tulu plants to be tested for fungal rot before being sold. However, infected plants less than 30 weeks old have generally not built enough fungal rot to be detected reliably. And many tulu plants are sold before they are 24 weeks old.

Which of the following, if performed by the govt ministry, could logically be expected to overcome the problem with their plan to test fungal rot.
