Application Tips
Do not exceed recommended rate and apply at appropriate growth stage for each crop. Apply product in warm
weather. Do not apply under drought conditions. Application must be made before the crop shields the weeds.
How it Works
Susceptible plants convert 2,4-DB to 2,4-D. Certain legumes do not convert it. 2,4-DB is translocated to actively
growing parts.
Expected Results
Weeds should die within 2 - 3 weeks of treatment. Smartweeds seedlings only stunted.
Restrictions
Rainfall
:
Rainfall before the foliage has dried from the spraying may decrease activity.
Grazing
:
Do not use treated crops for grazing of livestock or green feed until 30 days after application
