SOIL AND WEATHER CONDITIONS

KERB FLO requires moisture for root uptake. Best residual action is obtained in moist soils of fine tilth.

KERB FLO can be applied under frosty conditions but should not be used where run-off from the soil surface is likely.

Best results are achieved when growth of weeds (especially blackgrass and volunteer cereals) is slow, but transpiration continues. In mild autumns/winters, emerged weeds may take longer to be controlled, the residual activity of KERB FLO will be shortened and overall control may be reduced.

The efficacy of KERB FLO may be reduced in organic soils and in the presence of excessive surface organic debris, burnt straw, ash, or ploughed-up turf.

In winter field beans ensure a firm seedbed before spraying.

RESISTANCE

Strains of some annual grasses (eg blackgrass, wild oats, Italian ryegrass) 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.

WATER VOLUMES

Winter oilseed rape, sugar beet (seed crops), winter field beans, lucerne, brassicas (for seed production), clover (seed crops): Apply KERB FLO in 200 to 1000 litres of water per hectare. Apple, blackcurrant, blackberry, gooseberry, loganberry, pear, plum, raspberry, redcurrant, rhubarb (outdoor), strawberry (outdoor), lettuce (outdoor), forestry, farm forestry, forest nursery, hedgerow, ornamental plant production (Christmas trees only), amenity vegetation: Apply KERB FLO in 400 to 1000 litres of water per hectare. Ensure good ground cover.

APPLICATION EQUIPMENT

Do not apply through broadcast air-assisted sprayers.

All crops: Application may be made through a ground crop sprayer.

Forestry, farm forestry, forest nursery, hedgerow, ornamental plant production (Christmas trees only), amenity vegetation: KERB FLO may also be applied via a knapsack sprayer.

MIXING

Add half the required volume of water to the spray tank and begin agitation. Shake the container vigorously and add the recommended quantity of KERB FLO through the filter basket. When container becomes empty, wash out with water and add the washings through the filter basket. Rinse through the filter basket and add the rest of the water. Agitate while topping up the tank and continue agitation until spraying is complete. Spray immediately: do not allow the mixture to stand. Thoroughly wash all spraying and measuring equipment with water immediately after use.
