Strains of some annual grasses (e.g. black-grass, wild-oats, and Italian rye-grass) have developed resistance to 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 (WRAG) and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.

Repeated use of herbicides with the same mode of action can increase the risk of strains of weeds developing resistance to these compounds, leading to poor control. In order to minimise the risk, a strategy for preventing and managing such resistance should be adopted. Use products with different modes of action and from different chemical groups in sequence or tank-mix, in conjunction with effective cropping rotation and cultivation techniques. In all cases the recommended rate of use should be adhered to. Follow WRAG guidelines.

Key elements of the resistance management strategy for Katamaran: • Always follow HRAC & WRAG guidelines for preventing and managing herbicide resistant weeds. • Maximise the use of cultural control measures wherever possible (e.g. crop rotation, ploughing, stale seedbeds, delayed drilling, etc). • Use tank mixes or sequences of effective herbicides with different modes of action within individual crops, or successive crops. • For the control of herbicide resistant grass weeds, always use Katamaran in sequence with other effective graminicides with different modes of action. • Monitor fields regularly and investigate the reasons for any poor control.

SHAKE WELL BEFORE USE.

Fill the spray tank three quarters full with water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of Katamaran to the spray tank while re-circulating. Fill the tank with the remaining required amount of water and continue agitation until spraying is completed. On emptying the product container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely.

Apply 2.0 litres/hectare of Katamaran as a MEDIUM spray, as defined by BCPC. Katamaran should be applied in a recommended water volume of 200 litres/ hectare. Qualified recommendation

Katamaran may be applied at 2.0 l/ha in 100 litres of water per hectare although efficacy and crop safety at this reduced volume has not been evaluated.

Care should be taken to avoid overlap of spray swaths.

Wash sprayer thoroughly immediately after use, using clean water and following the guidance provided by the equipment manufacturer.

For all situations following or rotational crops must not be planted until four months after application of ‘Katamaran’. Any crop may follow normally harvested winter and spring-sown oilseed rape treated with Katamaran. Re-drilling due to crop failure Following or rotational crops must not be planted until four months after application of ‘Katamaran’. Plough to a depth of at least 150 mm before sowing or planting any succeeding crop.
