Figure 3:

Michigan maps showing county distribution of lesion nematode (A), needle nematode (B), stunt nematode (C), and total plant parasitic nematodes (D) in corn fields in 2018. The size of the dots correlates with the number of nematodes.

Figure 4:

Michigan divided into five different regions for corn nematode sampling. Pie-charts show regional nematode distribution during corn harvest time in 2018. Regions: Southeast (A), Northwest (B), North (C), Southwest (D), East/Central (E).

Figure 5:

Mean population density (nematodes per 100 cm3 of soil) of lesion nematode (A), stunt nematode (B), and needle nematode (C) in different tillage practices in Michigan corn end-of-season samples in 2018. No significant differences were observed between nematode population densities and different tillage practices (Tukey HSD, α = 0.05).
