Over the past several years many have had concerns about scouring rush creeping into crop production areas. Scouring rush is not a typical agronomic weed. It normally grows along fence rows, ditch banks, and low lying areas. However, in long term no-tillage production systems scouring rush is increasingly encroaching into crop production areas.
There have been a number of reports of Palmer amaranth up with newly emerged soybeans and cotton. There are various reasons for this development. The number one reason is pre applied herbicides were not activated by rainfall and the pigweed emerged with the crop. Continue reading
UT Cotton Scout School on Friday, May 25th at the West Tennessee Research and Education Center in Jackson. Registration will begin at 8:00 AM (no fee or preregistration required). The program will end with a box lunch and a go-to-the-field session for those interested after lunch.
Just by driving through Tennessee there is no doubt we are a corn state this year. It seems like everywhere you look there is a field of corn. Much of this corn will get the “layby” application applied over the next 10 days. Continue reading
Horseweed (marestail) still present in fields after dicamba and glyphosate applied 2 to 3 weeks ago has been the most common call of the week. Many want to know if the twisted up horseweed will go ahead and die or if it will recover (picture right).
Some of this can be determined by pulling some individual horseweed plants out of these fields and breaking the stem in half. If the stem is beginning to discolor or Continue reading
“Planting cotton is the second great urge known to man.” I am not sure who to accurately attribute that quote to, but I have heard it several times from Dr. Will McCarty, former Extension Cotton Specialist at Mississippi State University. Continue reading
There have been a number of reports of pre applied herbicides not becoming activated in corn. In most cases a significant stand of Palmer amaranth is up with the corn. Continue reading
The call of the last 10 days continues to be concerns on fomesafen carryover in corn. I had an opportunity to walk a number of these fields this week. The corn was showing the characteristic corn leaf vein chlorosis (picture right) caused by fomesafen carryover. It is not a real surprise as it is well known that fomesafen applied within 10 months of corn planting can carry over into corn. This has not happened often over the last several years because the summers/falls were wet compared to 2011. Wet soils will readily break down fomesafen. Another reason this has not happened in the last several years is due to Continue reading
