pigweed (including triazine-resistant), hairy
nightshade, Suppression of yellow
foxtail, witch
grass, lamb's-quarters. |
| Uptake and Translocation |
Following foliar application, rimsulfuron is rapidly
absorbed through the leaves and translocated in both xylem and
phloem. |
| Basis of Selectivity |
Inhibition of acetolactate synthase (ALS) enzyme
in susceptible plants leads to a rapid cessation of cell division
and growth. Tolerant species rapidly convert rimsulfuron to non-phytotoxic
metobolites. |
| Application Methods |
Postemergent, within the spike-3-leaf stage of
corn. Prior to initiation of flowering in potatoes. |
| Residual Activity |
Provides season long control of labeled weeds to
canopy closure. |
| Unique Characteristics |
Emerged grasses will be controlled by rimsulfuron,
but subsequent germinating grass weeds will not be controlled.
A non-ionic surfactant must be added at 0.2% v/v. Typical symptoms
of plant death (chlorosis, necrosis) occur 5-10 days after application,
depending on growing conditions. Do not use Elim on corn hybrids
with a Crop Heat Unit (CHU) rating of 2500 or less, or in geographic
regions with 2500 or less average seasonal CHU. |
