A herbicide for the control of a wide range of broad-leaved weeds in winter oilseed rape. Active ingredients are dimethenamid-p, metazachlor and quinmerac.

A residual herbicide for winter oilseed rape crops.


  • Ideal ‘catch all’ herbicide - important for a pre-emergence product
  • More consistent control in a dry autumn: three active ingredients provide three points of uptake – Root, emerging shoot and leaf
  • Less affected by drier conditions, a common occurrence in early autumn
  • Fits metazachlor stewardship guidelines

Why Banastar®?

Banastar® can be used on all varieties of winter oilseed rape and works on a wide variety of weeds. Banastar® is taken up via cotyledons and roots and takes maximum effect before, or shortly after weed emergence. Optimum results are obtained from applications that are made to fine, firm and moist seedbeds.

Banastar® works by employing a three-pronged approach to ensure maximum levels of weed control. The three active ingredients, dimethenamid-p, metazachlor and quinmerac each work on different parts of the seedling.

In terms of application timing, Banastar® may be applied pre or post-emergence of the crop before seven or more true leaf stage (GS 17)

More points of uptake = better control

Banastar® provides greater peach of mind, when applied as a pre-emergence herbicide. Applying pre-emergence covers the widest spectrum of weeds possible. Dimethenamid-p is more effective under dry conditions and there is better distribution on soil when sprayed, to form a better ‘seal’. Better soil absorption than metazachlor means more available at the surface, where required.

The three active ingredients provide three points of uptake, through the leaf, the emerging shoot and the root.
