Tank mixtures with Proxy

Which products can safely be tank mixed with Proxy (ethephon), the poa seedhead inhibitor?

Mixtures of Proxy plus Primo (trinexapac-ethyl) have been widely tested, and are not only safe to use, but also beneficial for promoting poa seedhead inhibition.

Other than this mixture, however, we suggest that you exercise great caution in mixing Proxy with other products. This is because the low pH (strong acidity) of Proxy makes it incompatible with many other products.

This is not to say that…
