 CHEMICAL WEED CONTROL FOR SUGARCANE

PREEMERGENCE TO ANNUAL WEEDS IN PLANT CANE

A. Early-fall planting (mid-August.to mid-October): Use'a modified ridge-and-
 furrow and apply herbicides immediately after covering and bedding when
 mature seed of good quality .is planted at the proper rate. Use proce-
 dure "B" if seed cane quality is poor or planting rate is low.

B. Late-fall planting (after mid-October): Cultivate until need for replanting
 "skips" can be determined. After replanting "skips" in stand or after
 a decision not to replant: clean-cultivate to a modified ridge-and-
 furrow and apply herbicides immediately with a directed or semi-directed
 spray to minimize wetting the cane foliage. Granular formulations may
 be applied over the plants.

 FOR ORGANIC SOILS

 10 qts/A Uspally requires a postemergence broadleaf weed
 control treatment at 1 to 2 months after appli-
 cation.

 8 to 10 qts/A .This combination will provide good grass and broad-
 + leaf weed control for several months under average
 2 qts/A .soil moisture and rainfall conditions.

 8 qts/A A commercial formulation of "Randox" and 2,4-D
 acid.

 Note "Randox" and "Limit" are not postemergence herbi-
 cides and will not control perennial or established
 weeds. Grass weed control is improved with good
 soil moisture or light rainfall and is decreased by
 heavy, persistent rainfall.

 6 qts/A Duration of good annual grass and broadleaf weed
 control is 2 to 4 months after fall or spring
S4 to 5 lb/A application. The combination also has postemergence
 activity against small grass and broadleaf weeds but
 cane foliage contacted by the combination will be
 : burned".


Provides good annual grass weed control which has
continued into the ratoon crop following applica-
tion. Usually requires a postemergence broadleaf
weed control treatment 1 to 2 months after appli-
cation.
