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 black-grass 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 efficiency 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 (e.g. black-grass, 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 and are available from your local Teagasc/independent advisor. 

WATER VOLUMES
Winter oil seed rape, winter field beans, lucerne: Apply KERB FLO in 200 to 1000 litres of water per hectare.

Pome fruit, top and cane fruit [apple, blackcurrant, redcurrant, gooseberry, raspberry, loganberry, blackberry, pear, plum], forestry, forest nursery, outdoor woody ornamentals, Christmas trees, lettuce (outdoor), rhubarb (outdoor), strawberry (outdoor): 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.

Knapsack applications: Add half the required amount of water to the knapsack. Shake the KERB FLO container vigorously and add the required amount to the knapsack, agitate the knapsack until the KERB FLO is fully dispersed. Top up the knapsack with the rest of the water and spray immediately, do not allow the mixture to stand.

Micro Herbi Application: Fit the Micron Herbi with the orange nozzle and the 0.19 inch OD breather tube. Any other size could result in uneven application. Add 375 ml KERB FLO to 625 ml of water in the spray bottle. Shake thoroughly to ensure all the product is in suspension. Then add 5 ml of an approved wetting agent and shake gently to ensure an even mixture.
The Herbi applies a 1.2 metre band. To apply the recommended rate of KERB FLO, the operator should cover 10 metres in approximately 13 seconds with sprayer held at approximately 45° to the horizontal. Under very cold conditions (near 0°C) flow is improved by holding the sprayer head at 50°to the horizontal.
Where crosswinds occur allow for drift by moving the Herbi head to the windward side of the tree row.
3 litres of KERB FLO is sufficient to make 8 litres of suspension, which will treat 6,660 metres of tree line.

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. Continue agitation while topping up the tank and whilst spraying.
Spray immediately: do not allow the mixture to stand.
Thoroughly wash all spraying equipment with water immediately after use.
