Banastar®
Banastar® is a residual herbicide that can be used on all varieties of winter oilseed rape for the control of a range of broad-leaved weeds.
Benefits
- Protects yield by early removal of weed competition
- A low resistance risk herbicide that provides a key start to the black-grass programme
- Provides excellent residual control of key broad-leaved weeds
- The three active ingredients are taken up at multiple points by the weed, providing more consistent control in dry conditions
- Quinmerac adds post-emergence and persistent activity to cleavers control
Why Banastar?
Banastar® is a residual herbicide for oilseed rape that offers excellent control of a wide range of weeds. Banastar® is taken up via the 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)

Dimethenamid-p
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.
