lady's
thumb, wild
mustard, velvetleaf,
common
ragweed. |
| Uptake and Translocation |
Following foliar application and uptake, prosulfuron
is translocated through phloem to meristematic tissues. Growth
of susceptible species ceases rapidly, followed by discolouration
of leaves; death takes one to three weeks to occur. |
| Basis of Selectivity |
Inhibition of the enzyme acetolactate synthase.
Tolerant species rapidly metabolize prosulfuron. |
| Application Methods |
Postemergent, within the 2 to 7 leaf stages of
corn. |
| Residual Activity |
Degradation primarily by soil microbial action.
Prosulfuron will provide a sufficient degree of control of later
germinating broadleaf weeds. Approved rotational crops are soybeans,
dry beans, peas, cerelas, and corn. See the label and Table
4-3 Herbicide Crop Rotation and Soil pH Restrictions and Table
4-4 Herbicide Crop Rotation and Soil pH Restrictions or rotational
restrictions. |
| Unique Characteristics |
Prosulfuron must be applied in a tank mix combination
with a reduced rate of dicamba.
Refer to the corn recommendation section for products and rates.
An adjuvant must be added at 0.2% v/v. Do not apply to corn treated
with a granular organophosphate insecticide. |
