The ultimate solution to this problem will be going back to a suite of native pollinators rather than depending on non-native honeybees.
"The flowers are wind-pollinated, with over 99% of pollination events being self-pollinations and the rest cross-pollinations.[6] "
No mention of ants, and the reference [6] says "Normally at anthesis, the lemma and palea are pushed apart temporally (lasting for 8–30 min) by lodicules swelling, and the pollen dehiscences from anthers and falls on the ovary to accomplish fertilization (de Vries, 1971)."
