Resistance
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 and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
Crop specific information
Katamaran can be used on all varieties of winter sown oilseed rape.
Katamaran may be applied pre or post emergence of the crop but for maximum activity application must be pre emergence of the weeds.
Pre crop emergence
applications should be made before the crop seed chits, which in warm moist soils may occur within 48 hours of drilling.
Seedbeds should be moist, firm and free from clods, but also see Restrictions/Warnings section.
DO NOT USE ON BROADCAST CROPS.
Post crop emergence
applications can be made from when the majority of the crop has two fully expanded cotyledons until the crop has eight true leaves.
Following crops
Any crop can follow normally harvested winter oilseed rape treated with Katamaran. Ploughing is not essential before sowing a following cereal crop, but is required for other crops.
In the event of crop failure in the autumn or winter, then only the crops listed below can be
drilled after the use of Katamaran:
Re-drilling the same autumn – winter wheat (excluding Durum), winter barley, winter beans,
winter oilseed rape may be sown after ploughing to a depth of 15 cm
Re-drilling the following spring – spring wheat, spring barley, spring oilseed rape, potatoes,
peas, field beans and brassicae may be sown after ploughing.
Mixing and Spraying
Apply 2.0 litres per hectare Katamaran as a MEDIUM spray, as defined by BCPC.
Katamaran should be applied in a minimum water volume of 200 litres/hectare.
Do not use filters finer than 50 mesh.
SHAKE WELL BEFORE USE.
Half fill the spray tank with clean water and start the agitation.
Pour in the required amount of Katamaran.
Add the remainder of the water and continue agitation until spraying is completed.
Rinse empty containers thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of safely.
Do not overlap spray swaths, particularly on headlands.
Avoid spray drift onto neighbouring crops.
