Registrations |
Corn (field, seed and
sweet) |
| Sensitive Weeds |
Annual broadleaf weeds,
including triazine and group 2 resistant biotypes. |
| Uptake and Translocation |
Readily absorbed by,
shoots, roots, stems and leaves and then translocated to other
plant parts. |
| Basis of Selectivity |
Inhibits the HPPD enzyme
found in photosynthetic cells of susceptible species. Symptoms
on susceptible plants are bleaching followed by necrosis. Tolerant
species rapidly metabolize mesotrione. |
| Application Methods |
Preemergence in field,
seed and sweet corn. Postemergence up to the 8-leaf stage of
field corn only. Postemergence applications require the addition
of a non-ionic surfactant. |
| Residual Activity |
Degradation primarily
by soil microbial action. Mesotrione will provide residual control
of annual broadleaf weeds. |
| Unique Characteristics |
When mesotrione is tank-mixed
with atrazine there is a synergistic effect and improved control
of broadleaf weed species. Mesotrione can be tank-mixed with
either a soil applied or postemergence grass herbicide for one-pass
weed control. Mesotrione has low volatility and poses a reduced
risk to nearby sensitive crops. |
