Very happy to share our new article available in Weed Research.

We compared the morphology, phenology and fecundity of waterhemp cohorts across five canopy types. Results revealed the suppressive ability of spring wheat and oat canopies.

A reminder for glufosinate applications with the variable temperature this week. If the humidity drops below 60% at application or temperature is below 75 degrees, waterhemp control becomes less consistent.
Plan applications accordingly to reduce the chance of escapes.

@jasonmauck1 What do you mean by zap? Weed zapper?

[GROW.IWM @GetRidOfWeeds]

Continuous-contact weed electrocution (commonly used in orchards) could offer a more flexible way for row crop farmers to zap inter-row weeds, but companies need to better adapt this tech to row crops before you’ll see these machines in corn, soybean or cotton fields.

Learn more about ongoing row crop weed electrocution research from Cornell’s Dr. @LynnSosnoskie and Texas A&M’s @Ryan_C_Hamberg and Dr. @MBagavathiannan in this article.

An update regarding the postponement of the upcoming SWSS Annual Meeting. Please do not cancel hotel reservations as we are working with the hotel to adjust any block rooms to the new meeting dates. Stay tuned and stay warm!

[Richard Roth, PhD @DrRichardRoth]

Come join our team at the @ISUFieldLab! We're looking for someone with experience operating equipment to lead field operations at the farm. Plot scale research and/or demonstration experience is a plus. The job posting should answer most questions, but feel free to reach out.

@CropsCover @GetRidOfWeeds @MBagavathiannan @TAMUWeedNinjas @OregonState @zassogroup You are correct.

for your question: It would likely take additional passes (more energy) - but I think it depends on which species you are trying to terminate. The lethal threshold varies by species.

Soil and plant moisture at termination also matter.
