Each of botanical pesticide powder to insert in plastic bag 0,25 kg size that has holed and every plastic bag contents one gram botanical pesticide. The results research that the aplication of pesticide treatmen juicy tuber leaf powder, neem leaf powder, the sweet flag rhizome powder, and greater galingale rhizome powder with the treatment of 1 g/kg tuber can controlling the sweet potato weevil (Cylas formicarius) in the sweet potato tuber at the storage.

It’s shown at parameter the cumulative mortality percentage is reach 70,00% at adult, the sum of egg at tuber only 8 egg/jar and the total of hole at the tuber surface is 604,40 hole/tuber/jar.
