You can delete Facebook apps connected to your account, but note that you have to delete each app at a time.

Facebook is great at all sorts of things, like keeping you in touch with your friend from eighth grade, giving you a place to show off photos from your trip to Georgia, enabling you to chat with your stylist, and sharing news stories of questionable veracity.
Where Facebook falls a bit short is in keeping your personal information private. In fact, sharing your info is rather a large money maker for them, and every time you log into a new app using Facebook, that's exactly what happens.
Any app you don't use you should delete from your Facebook account, both to keep your info private, and to simply clear clutter that can slow down your computer or phone.
To delete Facebook apps on mobile, follow these steps.
1. Open the Facebook app on your iPhone or Android and tap the menu icon, which are the three lines on the bottom of the screen.
2. Tap "Settings," and on the next page scroll to and tap "Apps and Websites."
3. Tap "Logged in with Facebook."
4. Tap the circle beside the app you wish to remove, then tap the blue "Remove" button that pops up.

5. Confirm the deletion by tapping "Remove."
1. Log into Facebook on your Mac or PC.
2. Click the downward facing arrow at the top-right corner of your screen.
3. Click on "Settings."
4. In the left hand column, click on "Apps and Websites."
5. Click on the button beside the app you wish to remove, then click the blue "Remove" box and click it once more to confirm.

Now repeat that as many times as you need to with any other extraneous apps.
