PGR Ideas

I sure like the current Plant Growth Regulators, they allow irrigation to happen at and before flag leaf so watering can be reduced during flowering. 
We had some crops last season where we used 2 PGR's such as AAC Schrader Durum, Trical Surge Triticale (forage specific but we are taking for seed), CDC Haymaker oat seed production
When doing two passes (our experience is with Manipulator) we have done:

• Full rate with herbicide even if its on the early side, and a full rate at proper timing (GS 32)
• 3/4 rate with herbicide and 3/4 rate at proper timing
• 1/2 rate early with herbicides and full rate at proper timing

• We don't use Manipulator on Barley and instead use Moddus

Are you doing a forage crop with lodging risk, consider a PGR trial? There has not been too much research around forage yields with PGR's but I feel like stems get bigger when the crop gets shorter meaning forage yield may not be down.
Always talk to your buyer/end users to be sure there are no issues before using, but I am not aware of any issues in the crops above.
