Disease Lesion Mimic

Seed Type: 
Corn

Disease lesion mimic is a physiological plant disorder or stress phenotype caused by mutant genes in hybrid genetic backgrounds. Hybrids across the industry are affected but not specific brands. Mutant gene expression is triggered by bright sunlight and high temperatures especially when plants are in saturated soil conditions up to tassel stage. Corn followed corn rotations are affected more than corn following soybeans. Leaf spotting or longitudinal striping symptoms look like disease development. It is called an abiotic stress disorder by university plant diagnostic labs.
