mustard, cocklebur,
stinkweed,
shepherd's-purse
and common
chickweed. Triazine-tolerant biotypes of lamb's-quarters,
redroot pigweed, common ragweed and common groundsel are also
controlled. Top growth of Canada thistle and nut sedge are controlled.
Field bindweed may be suppressed by two applications applied 10
days apart. |
| Uptake and Translocation |
Taken up through the foliage. Not translocated. |
| Basis of Selectivity |
Metabolism by tolerant species. |
| Application Methods |
Postemergence when weeds are small and actively
growing. Apply in 100-400 L water/ha. Crop must be in a tolerant
growth stage (see specific recommendations on label). Thorough
spray coverage is necessary. Use flat fan nozzles tilted 45º
forward. Use Assist
Oil Concentrate with Basagran. Reduce the Assist rate under
hot, humid conditions. Liquid ammonium sulphate or 28% urea ammonium
nitrate may be added to Basagran Forte or Basagran for improved
and more consistent control of velvetleaf and lamb's-quarters
in soybeans only. Pinnacle
may be tank mixed with Basagran Forte or Basagran for improved
pigweed and lamb's-quarters control in soybeans only. Basagran
Forte does not require additional adjuvants. Basagran Forte is
not registered for aerial application. Basagran is registered
for aircraft application for soybeans, dry and snap beans. |
| Residual Activity |
Essentially none |
| Unique Characteristics |
Corn and turf are tolerant at all stages of growth.
Bentazon is not volatile. Temporary crop injury can be expected
if bentazon is applied during hot, humid weather or if crop is
stressed (flooding, drought, cold). Cool weather or drought may
delay control. Rainfall within 6-8 hours after application may
reduce effectiveness. Since there is no residual activity, a new
flush of weeds may emerge after the first flush has been controlled. |
