It is apparent in a number of corn fields that the Pre applied herbicide has given out. In fields where the weed control is relying completely on a Pre applied herbicide, weeds, particularly Palmer amaranth, are emerging. Continue reading

The annual UT Cotton Scout School will be held Friday, May 27th. The school will be held in Jackson at the West Tennessee Research and Education Center. Registration will start at 8:00 AM, and the program will begin at 8:30 AM. A box lunch will be provided, and those interested can attend a “go to the field” session after lunch. Registration is FREE and pre-registration is NOT required. Topics covered will include cotton growth and development, identification of pests, beneficial insects and weeds (including those resistant to glyphosate). Live and preserved specimens will be available for viewing.
The call of the week has been concerns on the herbicide fomesafen (Flexstar, Reflex). A few farmers believe (and some are correct) that they have Flexstar carryover stunting corn. There is a 10 month wait to plant corn after a Flexstar application just for carryover reasons. If Flexstar is applied after mid-June and is coupled with a dry fall there is a chance for carryover. Corn suffering from Flexstar carryover will display very distinctive leaf symptoms. The corn leaf veins will turn yellow to brown and the midrib will often become distinctly yellowish/brown while the tissue between the veins Continue reading

We have seen a major flush of grasses and Palmer pigweed in many of the early planted corn fields. A follow-up herbicide application will be necessary in these cases. Continue reading
There have been a number of calls from folks who were disappointed in dicamba + glyphosate control on horseweed (marestail). Most of the applications were applied right before this wet cold period which is probably at least part of the reason for the poor control. Continue reading
Over the past several years, I have had numerous complaints of glyphosate not controlling goosegrass. With each of these past complaints, our field and greenhouse research showed that resistance was not the issue. Unfortunately, that has now changed. Continue reading
There have been a number of folks enquiring how to control fescue, bermuda grass, broomsedge, switchgrass and other warm season grasses in corn. Continue reading
