fluroxypyr spotlight dowagrosciences
Fluroxypyr (Spotlight) - DowAgroSciences
  • Cool-season tolerance is good
  • Warm-season tolerance is low and highly rate dependent
  • Will see as an ingredient in other 2- and 3-way broadleaf control herbicides
    • Ex. NuFarm Escalade (2,4-D + fluroxypyr + dicamba)
carfentrazone quicksilver fmc
Carfentrazone – QuickSilver - FMC
  • Triazolinone family
  • Post, contact activity, cell membrane disrupter
  • Rapidly absorbed, only limited translocation
  • No soil activity
    • t 1/2 - 2.5 to 4 d
    • non-mobile
  • Negligible volatility
why add carfentrazone
Why add carfentrazone?
  • Tank-mix with 2,4-D, 2,4-DP, dicamba, MCPP, MCPA, atrazine, glufosinate, glyphosate
  • Better activity in cool weather
  • Faster development of control symptoms
    • hours vs. days
    • complete control in 7 to 14 days
  • Better activity on spurges
