right, you dont have to beat him up (depending on his age) kids talk too much. maybe threaten him a little,lol. it is saddening to tell you to rip them out(make something else out of them) but from expierience kids parents listen to them and talk to each other.

I dont really think its your brothers fault.

Your his older brother and in his eyes you are "Cool".He probably was telling people my bro is so cool he is growing pot.

As Stinkyattic said sit him down without anger and talk to him.

I'm also jumping on the Talk to him without anger boat.

As a little brother, i'm sure he was bragging on you, and thats one of many things he told his friends. This one happened to be true.
Play it safe, let him know people go to jail for growing, and the more he talks about it, the more likely hes going to be indirectly at fault if something were to happen from it.
