Chapter: 231 (DBZ 37), P4.2/P6.2/P12.5
Context: Vegeta prepares to fire the Gyarikku-Ho
Vegeta: “Dodge this if you can!!!! Even if you save yourself, the Earth will be smashed to pieces!!!!! [ ] You’ll never block my Gyarikku-Ho…!!!! Turn to space dust together with the Earth!!!!!”
Goku: “x4!!!!!” *he uses the Kaio-ken x4*
Viz:
Steve Simmons Anime translation (Episode 31):
Vegeta: "I don't need this planet anymore! I'm going to crush you along with the rest of the Earth!
Go ahead and try to dodge this, if you can! Even if you do, the Earth will be blown to pieces!"
Note: Vegeta clearly says "uchuu" (space) in the second sentence here in reference to "space dust", equivalent to the Viz version having him refer to turning everything into ashes.
In all translations, Vegeta makes it very apparent he's going to destroy the Earth. Whether or not it'll be blown up as cleanly as Piccolo destroying the moon in the manga is debatable though, considering his space dust comment, but at the very least shows his blast could destroy the planet and pulverise most of it.
