Experiment 1: Does fungal-nematode interactions differ across corn genotypes?

• Is there an interaction between fungus and nematode to harm plant health?
• Is the interaction observed between different corn genotypes?
• Does the presence of the fungus reduce the number of nematodes recovered?
• If there is a reduction of nematodes recovered, is it different between corn genotypes?
