The complaints about herbicide drift run the gamut — drift from an adjacent field, drift from long distances, temperature inversion issues, plane getting in the wrong field, farmer getting his own fields mixed up, contamination in the load, carryover.
At a recent meeting at the Arkansas State Plant Board, new dicamba- and 2,4-D-tolerant crops were discussed. There were presentations by several university weed scientists and representatives of the respective companies.
If farmers go forward with only one weed control technology — regardless of which one it is — it could have a three- to five-year lifespan. Maybe shorter.
A new weed control technology could be dead before the seed industry gets completely geared up on variety choice and availability.
It would be easy to say the cleaner crop is due to the big increase in LibertyLink cotton and soybeans. I am sure that is some of it, but there are some good-looking Roundup Ready crops out there as well. More and more folks seem to be learning that we are in a fight and they are hooking up to do whatever it takes to win.
My list of things that were not said at the recent National Summit on Strategies to Manage Herbicide Resistant Weeds is not all-inclusive, but until we can come to grips with some of them there is little hope of moving forward.
The season has started out difficult in many areas of Arkansas — primarily due to the lack of rainfall. A lot of the residual herbicides applied in all crops have not been activated properly, which puts more pressure on the postemergence herbicide timing.
