Critical comments: maximum total dose: 2.5 l product / ha / crop. Latest time of application: Before 7th true leaf stage (GS 17). A maximum total dose of 1000 g metazachlor/hectare may be applied in a three-year period on the same field.
For professional use only. When Katamaran Turbo is applied pre emergence, it is important for crop safety to ensure physical separation of the herbicide from the seed. Ensure that the seed is well covered with soil to a depth of 15 mm. With direct drilled crops, harrow across the slits to cover the seed before spraying. Do not disturb the soil after application. Do not apply to broadcast crops until the crop has attained the two fully expanded cotyledon growth stage. Katamaran Turbo is suitable for use on all soil types as defined by Soil Texture (85) System, except sands and very light soils and soils containing more than 10% organic matter. Do not apply to stony soils; i.e. stones, flints or chalk readily visible on surface. On brashy and stony soils, Katamaran Turbo may cause some reduction in crop vigour and/or plant stand. Do not apply to cloddy seedbeds. Seedbeds must have a fine, firm tilth for optimum weed control. Loose or cloddy seedbeds must be consolidated prior to application. Do not apply when heavy rain is forecast and do not use on waterlogged soil or soils prone to waterlogging. Crop thinning or reductions in crop vigour can occur if there is very wet weather after application. Where a crop check has occurred, this normally grows out after a few weeks and yields are normally unaffected. Soil moisture is required for effective weed control via root uptake. Residual control may be reduced under prolonged dry conditions. Weeds germinating from depth may not be controlled. Do not apply Katamaran Turbo to crops suffering from stress, which may be caused, for example, by pests, disease, waterlogging, poor seedbed conditions or previous chemical treatment. Under frosty conditions a transient scorch may occur.
Extreme care should be taken to avoid damage by drift onto plants outside the target area.
Care should be taken to avoid overlap of spray swaths To reduce the risk of movement of Katamaran Turbo to water:- a. On clay soils, create a fine, consolidated seedbed to slow the downward movement of water. b. Do not apply Katamaran Turbo to dry soil. Moist soils have fewer and smaller cracks. c. Do not apply Katamaran Turbo if heavy rain is forecast, wait until after the event.
Katamaran Turbo is taken up via cotyledons and roots and takes maximum affect before, or shortly after, weed emergence. Optimum results are obtained from applications made to fine, firm and moist seedbeds.
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 Turbo:
Always follow 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 Turbo in sequence with other effective graminicides with different modes of action.
Monitor fields regularly and investigate the reasons for any poor control.
Katamaran Turbo can be used on all varieties of winter oilseed rape.
Time of application
Katamaran Turbo may be applied pre or post emergence of the crop but for optimum activity application must be pre emergence or early post-emergence of the weeds. Extreme care must be taken to avoid spray drift onto non-crop plants outside the target area.
Pre-crop emergence applications:-
should be made before the crop seed chits, which in optimum conditions may occur within 48 hours of drilling.
should only be made on medium and heavy soils (as defined by the ADAS Soil Texture (85) System).
DO NOT USE Katamaran Turbo pre-crop emergence when any of the following conditions apply:-
When crop has been broadcast.
The crop seed has started to germinate (i.e. 48 hours after drilling)
Seed is not covered with 15 mm of soil;
When heavy rain is forecast;
Dry, cloddy or open seedbeds;
Late drilled crops – as a guide these are crops drilled later than the first week in September in Northern England and Scotland and later than mid-September in the rest of the UK;
Stony soils, i.e. stones, flints or chalk are readily visible on the soil surface.
Post crop emergence applications can be made in the following circumstances:
When the majority of the crop has two fully expanded cotyledons and up to the sixth true leaf growth stage (GS 16);
On light, medium and heavy soils (as defined by the ADAS Soil Texture (85) System);
When seedbed conditions are not ideal for pre-emergence use;
When the seed is not covered with 15 mm of soil (as with broadcast crops);
To light, stony, brashy or gravely soils, particularly if heavy rainfall was forecast for the period following drilling;
When late-drilled crops are to be treated.
Rate of application
Apply 2.5 litres/hectare Katamaran Turbo in a recommend water volume of 200 litres per hectare.
Qualified recommendation Katamaran Turbo may be applied at 2.5 l/ha in 100 litres of water per hectare however this recommendation has not been supported by effectiveness or crop safety data.
For all situations following or rotational crops must not be planted until four months after application of ‘Katamaran Turbo’.
Following crops after normally harvested winter oilseed rape
Any crop can follow normally harvested winter oilseed rape treated with Katamaran Turbo. Ploughing is not essential before sowing a following cereal crop, but is required for all other crops.
Re-drilling due to crop failure
In the event of a crop failing in the autumn or winter, the listed crops can be drilled four months after the application of Katamaran Turbo:
cereals (excluding durum wheat),
spring oilseed rape,
peas and field beans.
Mixing and Spraying
Apply as a MEDIUM spray, as defined by BCPC. Katamaran Turbo should be applied in a recommended water volume of 200 litres/ hectare.
Never prepare more spray solution than is required. 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 Turbo to the spray tank while re-circulating. Fill up the tank with 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.
