You can use Widget Logic plugin.
or Conditional Widgets plugin.
2. Hide One Adsense Code In Single Post (single.php) Template.
Go to Appearance >>Editor >> Single Post (single.php).
Look for your Adsense code.
Now do this:
<?php if($post->ID != xxx): ?>
(Adsense code here)<?php endif; ?>
xxx is the ID number of the blog post.(Adsense code here)<?php endif; ?>
How To Find Post ID Number
You can find it by going to "All Posts" under "Posts".
Put your cursor over that particular post title.

For this example, the XXX is 357.

<?php if($post->ID != 357): ?>
<script type="text/javascript"><!--
google_ad_client = "pub-xxxxxxxxxxxxxxxxx";
/* 336x280, created 02/06/11 */
google_ad_slot = "6379290360";
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/s
how_ads.js"></script>)
<?php endif; ?>
in your single post template.<script type="text/javascript"><!--
google_ad_client = "pub-xxxxxxxxxxxxxxxxx";
/* 336x280, created 02/06/11 */
google_ad_slot = "6379290360";
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/s
how_ads.js"></script>)
<?php endif; ?>
