Broadleaf crops such as sugarbeets, red beets, peas, lentils, rapeseed, mustard, tomatoes and broccoli have been injured in field plant-back studies 1 year or less after application of Assert. Preliminary research indicates that these crops should not be planted within a minimum of 15 months after application of Assert. For additional broadleaf weed control, preliminary research indicates that Assert can be effectively tank-mixed with Glean and other sulfonylurea herbicides. Sharp reductions in wild oat control commonly results from tank mixes with dicamba. Remaining Research Thin concludes that Assert can effectively control wild oats and selected broadleaf weeds in small grains under the varied Idaho cropping conditions.
More research is needed, however.
Additional information must be available on the persistence in the soil as affected by soil type and pH, rotational crop safety, preplant and preemergence nonincorporated applications, tank-mix compatibility and varietal tolerance of wheat and barley.
