Hoste's conjecture on zeros of Alexander polynomials of alternating knots

Let $K$ be an alternating knot, and let $t \in \mathbb{C}$ be such that

$$\Delta_K(t)=0.$$

Hoste's conjecture. Then $\Re(t) > -1$. This conjecture concerns the location of zeros of Alexander polynomials for alternating knots. The source recalls it while analyzing zeros in rational and pretzel knot families; its general status is not resolved in the supplied context.
