Help Can't Disable Plugin For WordPress Theme

Hi Everyone, please am facing a problem right now. I run a wordpress blog and I use two diffrent themes, one for desktop and one for mobile.

I have some plugins setup in the wordpress blog which I want them to show, but I do not want the plugins to show on the mobile site; cause it makes the website load longer, please how can I stop this. Thank you
