1
Effects of Reduced Methyl Bromide Rates and Mulches on Nutsedge Control
  • Bielinski M. Santos James P. Gilreath Myriam N. Siham
2
Why controlling nutsedge?
  • Cyperus rotundus and C. esculentus.



  • Interference with the crop causing yield losses.
3
MBr Research
4
Methyl Bromide (MBr)
  • MBr phased out since January 2005.


  • Critical use exemptions.


  • MBr cost increase.
5
Impact of mulch on
weed management
  • Virtually impermeable films (VIF): More retentive than LDPE or HDPE.


  • Metalized: Few or no reports available on weed control.


  • Disadvantages:
    • Cost
    • Handling properties.
6
Objectives
  • Determine the MBr retention differences among mulch types.


  • Evaluate the effect of reduced rates of MBr on nutsedge control in combination with different mulches.
