Palmer Amaranth found in Northern Iowa.

Oh Joy...this is ridiculous.  Everyone better keep a eye on this.   I guess the danged CRP seed contained a bit of Palmer mixed in the seed.  The birds will go in the CRP and eat the seed and poop it all over the crop land or the cuffs of hunter`s trousers or the wind or wash down the hill or a machine picking it up if it drives through a waterway.

It`s some nasty stuff that I don`t know if crops can coexist with, it gets like tree trunks stopping a combine sickle cold.  It just laughs at Dicamba...maybe it`ll attract sudden death, white mold and aphids?   One can only hope   🙂

Yep great stuff for erosion control, massive root system.

BTW, why should you be immune, to this challenge?

Has been steadily moving 50 miles a year north and east..

Banvil resistant beans will just make this pest worse.

Well if might`ve not come up here for another decade if not for the contaminated CRP seed.  All these Bigshots around here put really good farms in the CRP and the better the soil type, the more they pay, $350/acre.  If this Palmer is like Waterhemp (1 million seeds/plant) ALS resistant, once it gets a start it really explodes.  i remember in the 90`s "Pigweed" turned into Waterhemp in about a couple years, you sprayed it thinking "WHY WON`T YOU DIE?" ...but yup the party is over and we still fight the waterhemp battle and there is starting to get gaps in the Flexstar GT control of that.

But when I was a kid spraying fencelines with 2,4-D it seemed like every year weeds were getting imune to that, if they got above a certain size.  So, I`m sure the Dicamba beans will have a short honeymoon.  But it sounds like they`re labled for only spraying in the V-stages, so about mid-June you`re done according to the label...I think mostly because of drift to neighbors.   Maybe everyone will have to plant Enlist beans and spray 5 times during the season, nailing the Palmer and waterhemp before it`s over 2"?   Stink the countryside up good all summer   🙂

 Last month I traveled in the western part of Kansas, saw thousands of acres of "banvil"  drift symptoms on beans. 

Some of it miles away from where it was applied in late July on wheat stubble after harvest. Saw it in both the north and south side of the state.

Banvil beans are going to cost a lot of spray people money. Down here many commercial spray companies will not put it in their equipment. Too many grapes, (wineries poping up everywhere) tomatoes, hay and flower beds in this area, let alone specialty beans. 

Doubt it will.be net profitable anywhere near where there are wind farms.

We have been using Dicamba and 24D for 30 years to control weeds including pigweed without destroying neighbors or our own crops It is another tool in the box that must accompany good judgement and a multichemistry approach.. Why is it going to suddenly become the disaster you all speak of. There is really not a lot of options we have.  I bet even naysayers are getting their orders in for the technology.

All the seed salesmen (and women) are saying the new dicamba formulation will be approved by next growing season so get your seed orders in.

After StarLink and two-three other goofs I am not going to plant any untill EVERYTHING is approved.
