I am trying to remove the action hooks added by SEO ultimate plugin for some pages. The way it is added in the plugin's class is

    //Hook to output all <head> code i changed the priority to 2
    add_action('wp_head', array(&$this, 'template_head'), 2);

The SEO plugin creates a global variable like this

global $seo_ultimate;
    $seo_ultimate =& new SEO_Ultimate(__FILE__);

In my plugin, i try removing it by

add_action('wp_head',array($this, 'remove_seo_header'),1);

    function remove_seo_header() {

         remove_action('wp_head', array($seo_ultimate,'template_head'));

But it does not remove the action. Can anyone point out where am I wrong?

You have to use the same priority, and you need access to the global variable:

function remove_seo_header() {

        array( $GLOBALS['seo_ultimate'], 'template_head' ), 2 

You can also foreach through the registered hooks like this:

function remove_filter_in_class( $tag, $function_to_remove, $priority, $class ) {
    if ( isset( $GLOBALS['wp_filter'][ $tag ][ $priority ] ) ) {
        foreach ( $GLOBALS['wp_filter'][ $tag ][ $priority ] as $key => $function ) {
            if ( is_array( $function['function'] )
                && $function_to_remove === array_pop( $function['function'] )
                && $class === get_class( array_pop( $function['function'] ) )
            ) {
                return remove_filter( $tag, $key, $priority );
