Final Verdict on First Field with Reported Poor Palmer Amaranth Control with Dicamba

Author: Larry Steckel, Extension Weed Specialist Comments Off on Final Verdict on First Field with Reported Poor Palmer Amaranth Control with Dicamba

I blogged several weeks back on the poor Palmer amaranth control with Engenia in a field in Fayette County.  We followed up by applying another application of Engenia on the still green Palmer 14 days after the first application.   I am glad to report that all the Palmer amaranth were controlled 14 days after the second Engenia application.

Will the Palmer Amaranth Die after an Engenia or Xtendimax Application???

Author: Larry Steckel, Extension Weed Specialist Comments Off on Will the Palmer Amaranth Die after an Engenia or Xtendimax Application???

The question of the week is will the Palmer amaranth die that is still green after an Engenia or Xtendimax application? The situation is that many pigweeds in some fields have not grown after an Engenia or Xtendimax application but still remain green going on 10 days or more after the application.  The question is will these pigweeds start to regrow?

Follow Up Questions on Reports of Poor Palmer Amaranth Control with Dicamba

Author: Larry Steckel, Extension Weed Specialist 1 Comment

The blog on inconsistent dicamba performance on Palmer amaranth has caused some follow up questions.

Is there any difference between Engenia, Xtendimax and Clarity for actual Palmer amaranth control? NO. I know from repeated research with all three that they all perform fairly well on a 1 to 4” Palmer amaranth.  They all often need follow up applications on Palmer that is larger than 4”.

Are PRE applied herbicides needed in Xtend soybeans?  YES. The folks to date who have had issues with dicamba performance were not using any PRE applied herbicides. It is hard to get good coverage in those thick mats of pigweeds where PREs have not been used.

In a March blog I noted the lack of horseweed (marestail) in many fields but thought an April germination event of this weed could come late to the party and pose a problem.  On occasion I make a good guess, as that has clearly been the case.  Continue reading
