WEED CONTROL

Herbicide Residue

Broadstrike (flumetsulam) is only available in prepackaged
mixtures with Dual, Treflan, Stinger (clopyralid), or Stinger +
2,4-D acid. Broadstrike may have a residue the year following
application. Degradation of Broadstrike is primarily affected by
soil pH. The rate of Broadstrike degradation increases as soil pH
increases. Risk of carry over is greater in low pH soils than in
high pH soils. Rotational crop restrictions for all premix
products containing Broadstrike are found on page 64 of the 1996
North Dakota Weed Control Guide in the table, "Rotation
Restrictions for Crops Grown in North Dakota".
