In the later stage of growth, spraying the whole plant with the mixture of 3g/kg and 2,4 and 5m T of 0.3g/kg was more effective in preventing sprouting. In addition, after the potato was harvested, methyl naphthyl acetate was sprayed on the dry soil, and then the potato was mixed with the dry soil. Methyl naphthalene acetate was used for 10 g / 500kg. Or according to 1000kg potato using 1.4kg potato sprouting inhibitor, the sprouting agent can be prevented by evenly applying the sprouting agent on the surface of potato pile.
