semicarbazone/benzoic acid. |
| Crop and/or Non-Crop
Registrations |
Field corn (silage and grain). |
| Sensitive Weeds |
Redroot
pigweed, common
ragweed, lamb's-quarters,
wild
buckwheat, lady's-thumb,
and velvetleaf.
Controls horsenettle
and horsetail
when tank-mixed with nicosulfuron/rimsulfuron.
Control is best when weeds are actively growing. |
| Uptake and Translocation |
Readily absorbed by roots, stems or leaves and
then translocated to other plant parts. |
| Basis of Selectivity |
Metabolism by tolerant species. |
| Application Methods |
Early postemergence to 6 leaf corn recommended. |
| Residual Activity |
Half-life in soil is approximately 30 days. Residue
carryover into the next season is not a problem when applied at
registered rates. |
| Unique Characteristics |
This product has a wider application window, a
lower use rate and has better activity on perennial weeds than
dicamba alone. Spray drift is toxic to sensitive plants in the
same manner as 2,4-D, thus similar precautions should be followed.
The auxin transport inhibitor, diflufenzopyr, will also be active
with other growth hormone herbicides such as 2,4-D
and clopyralid
and may cause crop injury if tank-mixed. Do not use additives
such as oils, ionic surfactants, wetting agents, sticking agents
etc. Do not apply when there is a risk of severe drop in night
temperature. Do not spray when temperatures are expected to exceed
27°C. Do not spray in high humidity or fog. Do not apply preemergence
on sandy or sandy loam soils. Do not till or cultivate treated
area for at least 7 days following application. The addition of
a non-ionic surfactant at 0.25% v/v plus liquid nitrogen fertilizer
28-0-0 at 1.25% is recommended under postemergence applications. |
