DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

Restrictions
DO NOT apply to crops affected by waterlogging or pest and disease.
DO NOT apply to crops subject to extreme daily temperature changes or affected by frost.
DO NOT apply to crops under stress as transient yellowing may occur which is outgrown.
DO NOT apply QUIDAM to any crop more than once.
Field beans and broad beans MUST NOT be sown within 12 months of applying QUIDAM.
When using on winter cereals, seed should be covered by 3cm of soil.

Resistance
Strains of some annual grasses (e.g. black-grass, wild oats, and Italian rye-grass) have developed resistance to a range of herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
Use of QUIDAM for control of resistant strains of annual grasses should only be as part of an appropriate resistance management strategy. This should include use of sequences with herbicides with different modes of action and cultural control techniques.

WEEDS CONTROLLED
For best results apply to a firm, moist seedbed which is free from clods.
Note: A pre-emergence application of QUIDAM will reduce levels of black-grass and Italian rye-grass, however it should only be used as part of a resistance management strategy including use of sequences with products with different modes of action and cultural control techniques.
