Azoles (and other antifungals) are indeed still used in the US and there is documented azole resistance in important opportunistic fungal pathogens such as Aspergillus in the US:

Table 1 in this paper gives estimated azole use in various countries. US is lower than many European nations but still nowhere near zero.

The GP mentions "staple crops". In the US, azoles are used more on corn, wheat and soybean seeds than they are the actual crops themselves. Rice, on the other hand, and others get direct applications to the crops.
Presumably, applying it to the seeds going into storage is safer than applying in the open environment, but it's probably redundant since the Google claims azole use in the US is increasing.
