@WiscWeeds @CropNetwork @_arsenijevic @WISoyCheckoff @derff53 @agronomybadger @badgerbean Similar economics for corn?

@clusteredbytes @llama_index Could this process be specific to a certain research journal? E.g. I have a subscription to a journal which houses current and archived issues on website. The report would be limited to articles from that journal only but that’s fine with me.

@simonmaechling This will be an interesting read. Thank you for sharing.

Acheiving excellent weed control in soybean research trial with metribuzin rates 8 oz and above @cornellweedsci @LynnSosnoskie @NYSIPM

@abgagservices I like this but also hate this at the same time. 😄

@jasonmauck1 Off top of my head*, Killing the winter annuals w/o glyphosate is possible with something like Audit 9:1. The app can be made fall or spring depending on growth. 7 day interval to soybeans. Can also incl metribuzin but may incr crop response. *Need to verify w/ labels

[Ryan Henry @RHenry_UPL]

@WiscWeeds @derff53 @wicorngrowers Looking forward to reading the results of this trial.

@burgwx @postage27 Which do you recommend? Your pic in tweet is the default iPhone app?

[Ryan Henry @RHenry_UPL]

@jasonmauck1 Would need to check chem label in case there is language that prohibits such use though.

[Ryan Henry @RHenry_UPL]

@jasonmauck1 Might be able to save some weight with an Ultra low volume application of the chem. Something like a 3-5 gpa setup using a peristaltic pump and air atomization setup. There was such research done at UNL, I can dig that up if of interest. Nozzles can be set to band down rows

[Ryan Henry @RHenry_UPL]

@jasonmauck1 I may be oversimplifying the setup though. Row spacing of crop and nozzles will be important. And need to control weeds nearest crop

[Ryan Henry @RHenry_UPL]

@jasonmauck1 I’ve had similar thoughts. Doesn’t seem necessary to be spraying e.g. glufos onto bean. Or have crop intercept a soil residual. Seems like a multi boom system that can band the herbicide down row middle w/ other boom foliar feeding , fungicide, etc to the crop makes sense?

@FVCJeffW @douglas_moffat @grantkevin13 ~ 10 years ago. The timing was always critical. If some of the kochia was already germinated in fall, metri was a bust but still seemed to hold back spring germinating kochia and Russian thistle. Especially with the sulfentrazone. Flumi + metri always looked good too.

[Ryan Henry @RHenry_UPL]

@douglas_moffat @FVCJeffW @grantkevin13 Metribuzin is an option for fall applications. We used to apply metri plus sulfentrazone out near Brule, NE in fall for kochia. Made a world of difference.

[Ryan Henry @RHenry_UPL]

@jasonmauck1 It would be interesting to do some measurements on weed seed bank in your fields with the poly/relay crop vs the mono crop fields

[Ryan Henry @RHenry_UPL]

@matt_montgo That looks like cutworm damage. Developing plant looks to be cut just below cotyledons in several plants. They probably overwintered on the debris/winter annuals.

[Ryan Henry @RHenry_UPL]

@svpino How structured does the data need to be for these type of applications? Can it come from a variety of users, formats (pdf, excel etc), be in tabluar and non-tabular forms?

[Ryan Henry @RHenry_UPL]

@Rishabh90428185 Thanks for sharing. I look l forward to reading this article

@WiscWeeds @derff53 @JoseJr_Nunes @gchudzik1 @_arsenijevic @ZaimUgljic @FFaleco @JacobFelsman @AhmadrezaMobli @agronomybadger Great work and great publication. Tables and pictures are very helpful.

@Dusty42402999 Interesting. Seeing these older promos are neat
