After the delayed pre-emergence herbicides, the next step will be early postemergence herbicides. With those, the objective is to kill any weeds that have emerged, and also to get some additional residual into the program.
Some herbicide drift complaints are due to miscommunication and some are due to planting a herbicide-tolerant field in the middle of several conventional fields or vice versa. Most of these situations could be prevented.
Anywhere farmers are gathered, herbicide resistance is the main topic of discussion. Growers are exchanging a lot of ideas among themselves about how they can best solve or avoid the problem on their farms.
The PigPosium organized by the University of Arkansas and co-hosted by Delta Farm Press was a great experience for me and I must admit to a lot of different emotions. Who would have ever thought you would see 800 or so folks (a high percentage were growers) get to a meeting an hour before starting time to spend the day listening to speakers talk about one weed — Palmer pigweed.
A key to success with the LibertyLink system is starting clean at planting. One big mistake this past year, especially later in the season, was farmers planting both LibertyLink and Roundup Ready soybeans into standing 2-foot pigweeds and hitting them with a burndown — usually a high rate of Ignite.
Using residual herbicides is something we must learn to do again. Everyone likes the “spray twice with two postemergence treatments and be through.” That was a nice program when you could kill them anytime you wanted to.
There is no doubt that this year’s rice crop was a big disappointment to a lot of good farmers. Of course, there were success stories and most of them I have heard came from early-planted rice. It seems that year in and year out early-planted rice beats late-planted rice.
