Enable / Disable breadcrumbs

Hi friend I need your help again.
Let me explain to you. What I would like is disable the breadcrumbs but not in all pages, just in all of them except one.

I tried this code, in my css:
.page_heading {
display: none;
}
But what I got was disable breadcrumbs in all of them. How can just enable or disable the breadcrums in just one specific page. ¿?

Ty again.. xD
