Identifying and Assessing Delayed Emergence and Reduced Yield from Glyphosate Residues in Seed Potato
Seed potato fields can unintentionally come into contact with glyphosate by physical drift, contamination of spraying equipment, inversions, or misapplication. Glyphosate translocates to the daughter tubers and can be stored there until planting the next spring. This results in delayed emergence when potato seed is planted the next growing season. Symptomology of potato clones with glyphosate residues may include erratic emergence, malformed leaves, multiple shoots from a single eye, and enlarged shoots.
