We give a global description of the Frobenius elements in the division fields of Drinfeld modules of rank 2. We apply this description to derive a criterion for the splitting modulo primes of a class of nonsolvable polynomials, and to study the frequency with which the reductions of Drinfeld modules have small endomorphism rings. We also generalize some of these results to higher rank Drinfeld modules and prove CM-lifting theorems for Drinfeld modules.
