The Langlands-Shahidi method over a global function field will be presented for the split classical groups. We will highlight the difficulties that arise in positive characteristic with local-global arguments. Important applications to functoriality for generic representations of the split classical groups to an appropriate GL(N) are then obtained when the Langlands-Shahidi method is used together with a converse of Cogdell and Piatetski-Shapiro. Finally, we will mention how to go from the weak functorial lift to the strong lift. This has an important application to the Ramanujan conjecture, due to the fact that it is a theorem of Lafforgue for GL(N).
