Q: What weedspray do you recommend to kill Wandering Jew?

A: The best spray of all for Wandering Jew is our Triclo.  I have used it personally on a large patch in Rotorua and it does a great job.  You may get some regrowth but a second treatment then does the job very nicely.  Use rate is 6ml/L of water in a knapsack always add Superwetter Penetrant at 1ml/l water.  For very persistent patches you can add glyphosate to the mix at 10ml/l water.

Some Extra Info

Spray WeedKillers to Kill Wandering Jew

Spraying is the preferred method of controlling larger infestations of Wandering Jew, beyond the size that can reasonably be hand-removed.  There are three effective spraying options, each with advantages for certain situations:

  • Triclo at 60ml + 10ml SuperWetter organosilicone penetrant per 10 litres of water.  This is the preferred option.  It’s the most effective and gives a very fast brownout.  However it is best when applied in the warmer months (say Oct-Mar).
  • Glyphosate 360 g/L at 200ml + 10ml SuperWetter organosilicone penetrant per 10 litres of water
  • Glyphosate 540 use 130ml + 10ml SuperWetter organosilicone adjuvant per 10 litres of water
  • Granny, then use 90g + 10ml SuperWetter organosilicone wetter per 10 litres of water.

This is the best option when you don’t want any soil residues, and when you are spraying close to waterways (say 5 metres).  Don’t spray directly onto the waterway.

  • MSF600 at 5g + Glyphosate 360 at 100ml + 10ml SuperWetter organosilicone penetrant per 10 litres of water.  This is a more effective option than Glyphosate 360 alone, and results in less regrowth.  Don’t use this one very close to water as the MSF600 will damage aquatic plants even at low (i.e. overspray) concentrations.

Combining the Triclo  and Glyphosate 360 (or Glyphosate 540 or Granny) recommendations into a single spray has also worked extremely well according to customer reports.
