An emulsifiable concentrate formulation containing 30 g/l (2.7% w/w) diflufenican and 300 g/l (27.3% w/w) pendimethalin. Also contains N-methylpyrrolidone and chlorobenzene.
For the control of certain germinating broad-leaved weeds in winter wheat, winter barley, winter rye and triticale.

DIRECTIONS FOR USE
OMAHA is a selective herbicide for use pre-crop emergence in winter rye and triticale and pre and post crop emergence in winter wheat and winter barley.
The product is taken up by germinating seedlings through the shoot and partially by the roots, with little translocation in larger plants.

 
RESTRICTIONS
DO NOT apply pre-emergence to winter crops drilled after 20th November.
DO NOT apply if crop is stressed due to water-logging, drought, nutrient deficiency, pest infestation etc.
DO NOT apply during prolonged periods of frosty weather. Frost following application may cause crop damage.
DO NOT apply if heavy rain is expected with 4 hours.
DO NOT overlap spray swaths.
Crops may suffer some transient damage such as bleaching which is normally outgrown without affecting yield.
DO NOT direct drill autumn sown broad-leaved crops following application of OMAHA in the previous crop.
DO NOT treat broadcast crops.
DO NOT roll autumn treated crops until the spring.
DO NOT harrow the crop at any time following application.
DO NOT apply to soils with greater than 10% organic matter.
DO NOT treat under-sown cereals or those due to be under-sown.
See 'Following Crops' section for further information.
DO NOT soil incorporate.
DO NOT disturb the soil after OMAHA has been applied.
Extreme care should be tak en to avoid damage by drift onto plants outside the target area.
 
WEED CONTROL
Application should be made pre-weed emergence, and the susceptibilities shown below are from application made pre-emergence of the weed.
CROP SPECIFIC INFORMATION
Crops
Post-emergence use on winter wheat and winter barley.
Pre-emergence use on winter rye and triticale.
Do not treat under-sown cereals or those due to be under-sown.
 
Application
Make only one application of OMAHA to the crop.
 
Rate of Use and Volume
Apply 3.3 l/ha OMAHA per crop in 100-250 l water/ha.
Ensure a good coverage of soil.
Apply as a MEDIUM spray (BCPC category).
 
Timing
For winter wheat and winter barley apply early post-emergence and before leaf sheath erect stage (GS 30).
For winter rye and triticale apply pre-crop emergence.
 
Soil Condition
Prepare a firm fine seedbed for best results, with clods no more than fist size. The crop should be sown to a depth of 32 mm. It is important to ensure that the seed is well covered. Good weed control depends on burying and dispersing of any trash or burnt straw before or during seedbed preparation.
Residual control may be reduced, under prolonged dry conditions, on soils with a high Kd factor, where organic matter exceeds 6% or where ash content is high.
For best results apply to a moist seedbed. Do not apply to dry, cracked or waterlogged soils.
Do not use on sands (Soil Texture [85] System) or very stony or gravelly soils due to risk of crop damage.
 
Mixing and Application
Ensure the sprayer is clean and in good working order.
Calibrate according to the sprayer manufacturers recommendations.
Half fill the spray tank with clean water and begin agitation. Add the required quantity of OMAHA to the tank and complete filling. Continue agitation until spraying is complete.
Do not leave the sprayer standing with the spray mixture in it for a long period of time.
Wash out the sprayer thoroughly after use, using a wetting agent or a proprietary tank cleaner.
