[Brent Griffin – Prairie County Extension Agent] Just want to visit with you today on some of the issues that are affecting soybean production here in Arkansas. And especially this early spring as the days have warmed up, the things out here are starting to grow. [Pictures of a field with weeds] Many of our winter annuals are starting to take off and grow, mainly our winter junk weeds and we need to be out in front of them this year and taking care of them. [Brent Griffin] And that’s mainly due to rising diesel fuel cost, just in the last few days fuel has increased twenty-five to fifty cents a gallon for farm fuel.
[Picture of a field with weeds. Slide – Spring Annuals; Glyphosate; 1.5 pints of 2,4-D] Just want to visit with growers on a few things and possibilities or potentials to apply for. One is an old standby of glyphosate. One thing that I would ask or suggest to our growers that when they do run glyphosate to control their winter annuals, that they put in at least a pint and a half of 2, 4-D for our broadleaves, especially for glyphosate resistant marestail. [Slide – Spring Annuals; Read Labels; Consult M P 144; Plant-back restrictions] Growers will need to make sure and read their label, consult their MP44 for university recommendations on plant-back restrictions. I know many labels of 2, 4-D for soybeans is a 14-day replant or plant back restriction, on rice it’s 21 days.
[Double Crop; 1.5 pints of 2,4-D; Harmony Extra for broadleaves] Also for growers who have planted wheat this year and looking at double cropping soybeans behind wheat, I still would recommend at least a pint and a half of 2, 4-D with their Harmony Extra applications [Brent Griffin] if their looking at spraying broadleaves out here in the field to help knock these resistant marestail out before they become too large and we have these weedy fields at harvest.
