Central Iowa | I'd like to get some feedback on this year's chemical program.
3 yr rotation is 1: Strip-till corn 2: Strip-till corn 3: No-till soybeans (15inch, and early planted)
Weeds are various winter annuals and some GRW followed by waterhemp. I'm sure there are more but those are the ones I know and see.
We are north of hwy 30 in central IA, so moderately flat and heavy dirt with potholes.
Corn Pre-emerge @ 10-12gpa
2qts Trizar (dual, callisto, atrazine) (gen. Lexar)
20oz gen. Roundup (Maybe hotter around the borders)
1.5lbs AMS
1gal/100 MSO
Corn Post @ 20gpa
2qts Trizar again
34oz gen. Liberty
3lbs AMS
1pint Atrazine 4L? (optional)
Bean Pre-emerge @ 10-12gpa
5oz gen. Authority First (sulfen-/cloran-)
2oz Zidua SC
20oz gen. Roundup
1.5lbs AMS
