Hedge Mustard (Sisymbrium officinale)
- Hedge mustard is also sometimes referred to as wireweed or tumble weed.
- It is an annual or biennial and germinates mainly in the autumn. Hedge mustard has a small yellow flower that appears from spring to autumn.
- It is very common throughout the Waikato and Bay of Plenty.
- As the stems mature they become very hard and wire like, hence the alternative name of wire weed.
Control of hedge mustard
- In established pastures the best and most economical products for you to use are Pasture-Kleen* Xtra or Maestro herbicides. Both of these products will suppress clover growth for a short period of time. They are best applied as a broadcast treatment in the autumn and winter when the weed is at the seedling stage.
- Select* and Preside* herbicides are two new pasture and clover selective options. Both of these products work best when the plant is at the seedling stage.
Neither Select nor Preside will suppress clover and therefore are used predominantly when you have newly sown pasture to spray.
