Cotton Consultant's Corner:
Worked with Danny Bennett, a well known consultant, at the University
of Georgia where I received a degree in Agronomy
It’s not to the point that we will walk away from a field, but we know there are some fields with pockets of weeds that we will have trouble with.
However, even though resistance is spreading, everyone is working together to come up with a game plan to combat it. For example, whether we have resistant Palmer amaranth or not, we’re going to Valor and Roundup at burndown and using Prowl, Staple and Reflex behind the wheel at planting. We’re dusting off the old playbook so to speak.
For growers who aren’t dealing with the resistant Palmer amaranth issue yet, I would recommend paying attention to timing and don’t skimp on rates. Many times there is the misconception that you have to wait until the 4-leaf stage to spray Roundup. I think it’s better to spray Roundup as soon as the cotelydon uncurls because although a lot of weeds are resistant, many are just less susceptible after they get some age and size on them. When weeds are small and the cotton is small, you can start clean and end up clean. Monsanto’s pilot preemerge rebate program is going to help Southeastern growers, too. You have to keep your receipts and adhere to certain criteria, and Monsanto will rebate for partial Valor and Parrlay purchases on an acreage basis. There are many ways that resistance can spread – with birds or even pollen traveling in the air.
Monsanto is conducting a lot of research on this subject. My Dad and I farm together and are paying more attention to timing and calibration. We check everything – planters, spray rigs, etc. I do this for my growers, too. You have to be precise with rates, pay attention to ground speed, use new tips and the proper amount of water. As for impacting cotton acres in my area, the price of commodities is a greater factor than resistance. My growers are above average and quick to adjust to adverse conditions. They are still farming because they easily embrace new chemistry.
