Conditional for mobile check in WordPress

Hi thanks for your tutorial, i’m trying to remove all the sidebar, i tryed with:

add_action(‘template_redirect’, ‘remove_sidebar_on_mobile’);
function remove_sidebar_on_mobile() {

if ( !wp_is_mobile() ) {
remove_action(‘genesis_sidebar’, ‘genesis_do_nav’);

}

}

But i’m not sure if it will work, could you help me please?
Many thanks vincenzo
