How can you control potato sprouts? Normally potato sprout inhibition is done by using chemical inhibitors such as maleic hydrazide, CIPC or chlorpropham. Irradiation is also a good method of controlling the potato sprouts. With the increasing demand of organic potatoes, research is being carried out on organic control of potato sprouts.

There are two types of sprout inhibitors registered for use on potatoes in Canada. One is applied as a foliar spray during the growing season while the other is applied as a fog throughout the ventilation system of a potato storage AFTER the potatoes have cured, or as a spray on packing lines.
