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
There have been a number of calls on corn that is showing some stunting and interveinal chlorosis (Picture right). In some cases the injury is more substantial with some leaves showing some burn. The reason for some of this injury is fomesafen (Flexstar, Prefix, Reflex, Dawn, Rhythm) carryover from last year. Continue reading
Corn planting is winding down. The post application timing for corn has now started. There have been a number of calls from folks who are concerned they will get poor weed control spraying this week with the cooler night time temperatures. Continue reading
Much of the Palmer amaranth that is now 3 to 5” tall is flowering. Quite a few folks have asked what the reason is for this early flower. The Palmer amaranth has been triggered to flower by the short day length of March and now early April. Quite literally the Palmer amaranth that has emerged thinks it is late August or September. Palmer amaranth that we are most familiar with emerges from late-April through June. Continue reading
