Using Correct Nozzles Correctly: Thoughts on the Additional Nozzles Added to XtendiMax Label

Author: Larry Steckel, Extension Weed Specialist No Comments

The fifth blog on stewardship of XtendiMax and Engenia on Xtend crops will revisit nozzles. Just this past Friday the EPA approved the use of 20 other nozzles and/or orifice sizes besides the TTI 11004 for XtendiMax.   The additional nozzles on the list are good with respect to having more options but keep in mind that the nozzles are only approved if used at the designated operating pressures listed on that website.  Continue reading

Using the Correct Nozzles Correctly 2

The fourth blog on stewardship of XtendiMax and Engenia on Xtend crops will revisit nozzles. Dr. Bob Wolf, a leading expert on nozzles, wrote me after he read my last blog and stated that his research would suggest that the ideal pressure range to run TTI11004 nozzles on is between 45 and 60 PSI.  I had suggested 30 to 60 psi.

Xtend Crop Herbicide Stewardship 3 – Watch the Wind

Author: Larry Steckel, Extension Weed Specialist Comments Off on Xtend Crop Herbicide Stewardship 3 – Watch the Wind

The third blog on stewardship of XtendiMax and Engenia on Xtend crops will focus on application as affected by wind speed.  The supplemental labels for XtendiMax and Engenia use in Xtend crops read the same with respect to what wind speed these herbicides can be applied. The labels indicate that the optimum wind speed window to apply either herbicide is between 3 and 10 mph. Continue reading

The second blog on stewardship of XtendiMax and Engenia on Xtend crops will focus on nozzles.  There is only one labeled nozzle and one orifice size that can be used to apply XtendiMax or Engenia over Xtend crops. That nozzle is Spraying Systems Turbo Tee Jet air Induction 04 (TTI11004) nozzle. Continue reading

Xtend Crop Herbicide Stewardship 1 – Using and Stewarding the Correct Herbicides

Author: Larry Steckel, Extension Weed Specialist Comments Off on Xtend Crop Herbicide Stewardship 1 – Using and Stewarding the Correct Herbicides

A lot of labels on herbicides for the new herbicide trait technologies have arrived. The label to spray XtendiMax on Xtend soybean and cotton was granted in late November.  The label to apply Engenia to Xtend soybean and cotton was approved ten days ago.  This past Friday the EPA approved the label for Enlist Duo on Enlist crops for Tennessee.

I will be writing a series of blogs on stewardship of these herbicides focusing mainly on Xtend crops as Enlist will be planted on few acres in Tennessee in 2017.  We also put together a 30 minute training module on stewardship of these herbicides as part of the pesticide re-certification that many applicators will take this year.  Also, stewardship of these herbicides will be discussed in full at all the county producer meetings put on by UT Extension.  I highly encourage everyone to attend one of these meetings.

The first of these blogs will focus on utilizing and stewarding the correct herbicides.  Judging from calls there is a lot of uncertainty and in a few cases, some misinformation, out there about XtendiMax and Engenia. Continue reading
