We used 32 oz of origional max (22 oz is full rate) on roughly 90% of our beans this year.   First trip was closer to 22 oz, then 32 oz were used on the last two.  Strip till/no-till means another trip with the sprayer.  On our conventional tilled ground, one shot of 22oz and the last at 32 has worked beutifull.   

Thinking of using a pre put on with the F.C. for next year. Also small rate of Harmony mixed with pre and the follow up shot of rup, Lambsquarters are tuff!

Long story short, I think its not working like in years past.

Good Luck
