Active materials
A emulsifiable concentrate formulation containing 18.75 g/l diflufenican and 300 g/l pendimethalin. Also contains N-methylpyrrolidone and chlorobenzene.
For the control of certain germinating broad-leaved weeds in wheat, barley, rye and triticale.
 
DIRECTIONS FOR USE
RESTRICTIONS
DO NOT apply pre-emergence to winter crops drilled after 20th November.
DO NOT apply if crop is stressed due to waterlogging, 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 CHURCHILL 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 undersown cereals or those due to be undersown.
See ‘Following Crops’ section for further information.
Avoid spray drift onto neighbouring crops.
Do not soil incorporate.
Do not disturb the soil after CHURCHILL has been applied.
 
CROP SPECIFIC INFORMATION
Crops
Pre-emergence and post-emergence use on wheat and barley. Pre-emergence use on durum wheat, winter rye and triticale.
Do not treat undersown cereals or those due to be undersown.
 
Application
Make only one application of CHURCHILL to the crop.
 
Rate of Use and Volume
Apply 3.3 l/ha CHURCHILL 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 up to leaf sheath erect stage (GS30). For durum wheat, 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.
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.
Do not use on soils prone to waterlogging.
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.
 
Following Crops
Plough to 150 mm and thoroughly mix the soil before drilling or planting any following crops (either after crop failure or normal harvest).
CROP FAILURE: If a crop fails for any reason, only re-drill with winter wheat or winter barley, after ploughing. A period of 5 months must lapse after ploughing before spring crops of wheat, barley, peas, field beans, carrots or edible brassicas may be drilled.
NORMAL HARVEST: In the Autumn following normal harvest, only drill winter cereals, oilseed rape, field beans and leaf brassicas. In the Spring following normal harvest, only the spring crops listed above (under CROP FAILURE) can be drilled.
Occasionally seedlings of brassica crops may exhibit slight discoloration of the cotyledons, which is normally outgrown without affecting subsequent growth.
A minimum interval of 12 months must elapse between application and sowing red beet, sugar beet and spinach.
Where diflufenican containing products are applied to successive cereal crops, levels of diflufenican will build up in the soil. Even with ploughing to 150mm and thorough mixing of the soil, there may still be a risk of damage to following crops of onions, leeks, other allium crops and clover. As a precaution, users who rent out their land to growers of these crops should not use diflufenican containing products in successive years before renting out that land.
Before rye grass is drilled after a very dry season, plough or cultivate to at least 15cm.
 
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 CHURCHILL 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.
Extreme care should be taken to avoid damage by drift onto plants outside the target area.
