The adaptable autumn herbicide, bringing together the complementary combination of active ingredients flufenacet and picolinafen for both residual and contact activity. Excellent efficacy against a range of grasses and broad-leaved weeds.
- Effective against a wide spectrum of grass and broad-leaved weed species.
- Fast acting on grass control, which reduces competitive pressure at early crop development stage.
- No rotational or following crop restrictions.
Quirinus® is a suspension concentrate containing 50 g/l picolinafen and 240 g/l flufenacet. This herbicide has residual and contact activity for the control of a range of grass and broad-leaved weeds in winter wheat, barley, rye and triticale.
This adaptable autumn herbicide has three benefits in one: broad spectrum weed control, flexibility and easy handling.
Quirinus® can be applied at pre-emergence or post emergence until the start of stem elongation BBCH 30.
The formulation of the two active ingredients makes Quirinus® an effective herbicide solution that is flexible to fit into any situation. The half-life of picolinafen means there are no issues caused for following crops.
For many comparable products, herbicide resistance has been a growing trend. Quirinus® has proven to be effective against Black-grass, Annual meadow grass, Italian Ryegrass and annual broad-leaved weeds.
Picolinafen – the performance partner
Picolinafen is the performance partner, an ideal combination with flufenacet that brings a different mode of action. Picolinafen has a complementary effect on flufenacet, it broadens the broad-leaved weed spectrum, speed of activity and grass-weed efficacy.
In areas with heavy black-grass infestation, no single product can do the job alone. Stacking and sequencing programmes are necessary to get sufficient control. Quirinus® can be used as a tank mix partner with Stomp Aqua to get maximum control.
Application and timing
More consistent control is achieved from early application:
pre-emergence up to 1-2 leaves
- Broad-leaved weeds:
Pre-emergence up to 2-4 leaves
In high grass pressure situations tank mix with different actives or products e.g. Stomp® Aqua and diflufenican.
At later post-emergence timings tank mix with a contact acting graminicide.
