A residual herbicide for the control of a wide range of weeds in winter oilseed rape and several other agricultural and horticultural crops
A suspension concentrate containing 400 g/L of propyzamide (35.3 % w/w).

IMPORTANT: This information is approved as part of the product label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

Take care to avoid local overdosing.
Do not make more than one application of PROPER FLO within 9 months to the same area of land.

PROPER FLO can be used on all soil types with the following exceptions:
1. Do not use on soils containing more than 10% organic matter.
2. Do not use on winter fi eld beans grown in certain soil types. See RECOMMENDATIONS.

Soil texture (85 system)
Textural group /Textural class
Sands/ Coarse sand, sand, fi ne sand, loamy coarse sand
Very light soils/ Loamy sand, loamy fi ne sand, coarse sandy loam
Light soils/ Sandy loam, fine sandy loam, sandy silt loam, silt loam (85)
Medium soils/Sandy clay loam, clay loam, silty clay loam
Heavy soils/ Sandy clay, clay, silty clay

PROPER FLO requires moisture for root uptake. Best residual action is obtained in moist soils of fine tilth. PROPER 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 PROPER FLO will be shortened and overall control may be reduced.
The efficacy of PROPER 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

Strains of some annual grasses (eg 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 by the Weed Resistance Action Group and copies are available from your distributor, crop adviser or product manufacturer.

Water volume
Apply PROPER FLO in 200 to 1000 litres of water per hectare in winter oilseed rape, winter field beans, lucerne. Apply in 400 to 1000 litres of water per hectare in all other crops. Ensure good ground cover.
Winter oilseed rape
PROPER FLO can be applied after the use of an approved specifi c graminicide applied in accordance with the manufacturer’s recommendations.
Miscellaneous, including seed crops and lettuce See RECOMMENDATIONS.
Processed crops
No taints have been detected in tests with treated fi eld crops. Consult your processor before use

Control of black grass
Established (well-tillered) black-grass is moderately susceptible: Where populations of black-grass and/or volunteer cereals exceed 50/m2 PROPER FLO should be applied in an approved tank mix with an approved graminicide in accordance with the manufacturer’s recommendations, or following an effective approved graminicide to ensure optimum weed control.
Deeper germinating black-grass within the soil profi le could reduce product effi cacy. Where partial resistance to the partner graminicide is known to exist the dose of PROPER FLO may be increased to 2.1 litres/ha. This may also be done if applications are made early in the season, under warm conditions and an increase in the duration of residual control is required (see Soil and Weather Conditions above).
Where high levels of resistance to the partner graminicide occurs there is no advantage of adding this graminicide to PROPER FLO for black-grass control, and PROPER FLO even at 2.1 litres/ha will not give acceptable levels of established black-grass control in these circumstances.

Time of year Winter oilseed rape 1 st October to 31st January
Timing stage of crop As soon as possible after 3rd true leaf stage Crop selectivity is by depth protection. Factors which cause shallow rooting may reduce crop selectivity

Time of year Winter field beans 1st October to 31st January
Timing stage of crop As soon as possible after 3rd true leaf stage Crop selectivity is by depth protection. Factors which cause shallow rooting may reduce crop selectivity

Time of year Winter oilseed rape 1 st October to 31st January
Timing stage of crop Winter field beans: within 7 days after drilling but before crop emerges

Time of year Lucerne
Timing stage of crop Established crops grown for at least 1 season. Not less than 7 days after last cut

Time of year Lettuce
Timing stage of crop Before or after drilling

Soil type (soil texture (85 system) Winter field beans: Use only on medium or heavy soils with less than 10% organic matter Other crops: all soils with less than 10% organic matter

Add half the required volume of water to the spray tank and begin agitation. Shake the container vigorously and add the recommended quantity of PROPER FLO through the fi lter basket. Rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to the sprayer through the fi lter basket and dispose of safely. 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 and measuring equipment with water immediately after use

Do not apply through broadcast air-assisted sprayers. All crops: application may be made through a ground crop sprayer. PROPER FLO may also be applied via knapsack sprayer in lettuce (outdoor), forest, forest nursery, outdoor woody ornamentals, rhubarb and pome fruit orchards. Applying 500 L water/ha, 140 ml of PROPER FLO in 20 L of water allows to spray 400 m2 through a knapsack sprayer (3,5 L PROPER FLO/ha).
