You are correct, glyphosate is a chemical in the herbicide “Round Up” and it's used on many fields of fruits and vegetables (potatoes included) when needed to control the weeds. It is also only used BEFORE potato planting or right after, but before the potato comes out of the ground.

Do organic potatoes have sprout inhibitors?

Ethylene As a Sprout Inhibitor

The best part is that ethylene is considered natural and hence finds its usage in the European Union for Organic Potatoes. Ethylene-based sprout inhibition has been quickly welcomed in the potato chain because it is both safe and cost-efficient.

What are the two plant growth inhibitors?

Growth inhibitors for plants are ethylene and abscisic acid. Examples are auxins, gibberellins, and cytokinins. Plant Growth Inhibitors. These chemicals inhibit growth and promote dormancy and abscission in plants.
