Hey Hank

[ECIN]

Just wondering if you got your fall spraying done . 

[hanktbd]

Yep. Scouted everything and just ended up spraying the one field where I have been having some marestail issues. Post application on beans in that field in 2012 was untimely and too dry and been struggling to get good control since then so hoping this will help. Found a lot of marestail plants about 2 to 3 inches in diameter in that field just before we sprayed a few weeks ago. Kinda hard to tell how effective the spraying was with the colder weather, but expect that next spring will tell the tale.

What did you end up using. I'm thinking of a late March early April burndown on bean ground with something to get the early mairstail.

Finally was able to get my fall spraying finished. I thought it was a little aggressive, but my crop consultant said I would thank him next spring. I guess time will tell. Now onto other things like fall top dressing of winter wheat.

Buck,

I am not the right guy to ask about herbicides. I do know the mix included some 2,4,D. Herbicide action modes and proper usage is probably my weakest area of farming knowledge. I try to learn from posters on this site and others and tend to rely heavily (maybe too heavily) on the recommendations of my co-op guy. Has generally done a good job of keeping the fields clean, but I suspect my costs are higher than necessary. I believe ECIN has a lot of experience and expertise at this and does some custom spraying also.

Shaggy,

This is my first year to plant winter wheat. What type of fertilizer do you topdress, how much should one use, and what type of yields should one shoot for? I think the average yield for this area is around 70 bpa and was considering replacement fertilizer application but no idea of proper timing or type of N to apply. This field raised 224 bpa corn last year, and I generally plant beans after the corn, but is HEL ground so the wheat rotation is to hopefully improve the erosion control.

So Hank you let the Co-op spray right ?  And if you sprayed the marestail in the rosette stage - buddy you hit a home run - that is the best time to spray them with 2-4-D

Heres a picture of Rosette stage marestail .

wished I would had you leave a strip for a plot -- that would make you a believer - lol

Good luck

Ken

Thanks ECIN,

That is exactly what 98% of them looked like. Saw a couple that were alittle bigger - maybe 4 inches across and an inch tall rather than flat, but most looked just like the pics you posted. We hit them with 2,4,D and some other stuff the co-op claimed was working well about 2 1/2 weeks ago.

Tough question to answer Hank without knowing what your residual N was after your corn crop. Most of my wheat followed a corn crop this year with 20 units of residual N. I applied 50 units at the time of planting (about 7 weeks ago) along with P and a blend of micros. We had above average summertime precipitation here (Central Kansas) and decent fall precipitation, so I'm planning on applying an additional 70 units before years end. 70 BPA would be an above historical average for this area, but that is generally my goal each year.

Hank, your in similar conditions as I for wheat. Where Are you? Avg round here is higher than yours

No fall n unless your in Kansas or the south. The studies show it doesn't pay in the wet lands. You lose N !!!!!!!! Esn does not pay. At all. Only improves protein.

Lately, we have been using 150n here. N+2 fungicides improves yield dramatically. Take one away and things fall apart. Our extension specialist has done the research. I told buck to spray for scab this winter too.. Guess what... He didn't get downgraded to feed like his neighbors. Split apps give small increases... It depends on how many tillers you have at grew up . If your plants break the surface in he spring, all at once!! You really gotta do your homework on splits if you wanna make it pay. Just don't go out in feb and let everything leach away... Please!!

If you didn't do in row p, your 8bpa behind right out of the gate... If you worked the ground, your behind. Notill. It's the only way to grow wheat. I work ground for corn/ Soys. But long term research says you get nothing for tillage in wheat

Also, 10 pounds of S adds 3 or so bushels, as the Ontario data would suggest.
