What can be done in the field now?
Soil Sampling: It is a good time to finish up soil sampling if you have not already done so.
Burndown Applications: Get out a good burndown now. It become more difficult to control some weeds the closer we get to planting if no applications were made in the fall.
Italian Ryegrass: For smaller ryegrass clumps 32 - 40 oz of Paraquat should be sufficient, however for larger clumps apply 40 oz of Paraquat + 3 oz of Metribuzin. Select is another option, however there is a 30 day plant back interval for most crops except for cotton and soybean.
Marestail/Horsetail: Valor at 2 oz rate is still recommended for residual pre-emergence control.
Further Recommendations: Make sure to check out pages 21 - 29 for all burndown recommendations. Also take note of the sensitivity of major Arkansas field crops to commonly used herbicides on page 29. Last note, make sure to pay attention to the plant-back recommendations for burndown herbicides in the publication: MP519, which you can access by clicking on it below:
