Selective contact and residual herbicide for the use in winter and spring cereals.
Suspension Concentrate (SC) containing 500 g/l Diflufenican. Selective contact and residual herbicide in spring wheat and spring barley, winter wheat and winter barley, durum wheat, rye, oats and triticale for the control of annual dicotyledons and grasses.
DIRECTIONS FOR USE
STRIDE DFF is a suspension concentrate formulation, which is used as a selective contact and residual herbicide in winter and spring cereals to control annual dicotyledons and grasses. Under favourable growing conditions, the residual activity can last for up to 8 weeks after application. The level of effective residual control may be reduced under dry conditions, when poor coverage of the soil surface is achieved, when the crop is planted in non-wetting sand or where soils have a high content of clay or organic matter.
The product is taken up by the shoots of germinating seeds and seedlings. Susceptible weeds germinate but show immediate chlorosis followed by a mauve-pink discoloration. The chlorosis spreads with the aerial growth and the plants become necrotic and die back.
After application, some transient crop discolouration may occur, which will have no effect on the subsequent growth.
TRIDE DFF can be used pre-emergence in winter and spring wheat, durum wheat, winter and spring barley, rye, oats and triticale, or post-emergence in spring wheat and spring barley, winter wheat, durum wheat and winter barley.
Maximum number of applications: one per crop. Do not apply when heavy rain is expected within 4 hours or on crops suffering from stress, frost, nutrient deficiency, excessively moist or dry conditions, pest or disease attack or pre-emergence applications.
Do not use on other cereals, broadcast or undersown crops or crops to be undersown.
Do not apply to soils with more than 10% organic matter.
Use on sands (soil texture  system) or very stony or gravely soils may result in crop damage.
Do not harrow after application nor roll autumn-treated crops until spring.
Avoid drift onto neighbouring crops.
CROP SPECIFIC INFORMATION
STRIDE DFF can be applied from shortly after sowing until before the 1st node detectable stage (GS31). Seed beds should be fine and firm and should not contain clods greater than fist size. For optimal efficiency, it is advised to apply under moist conditions at or after application and rainfall during the first weeks after application.
On weak plants, a colouring of the first leaf can occur. This will have no impact on yield.
Drill crop to normal depth (25 mm) and ensure the seed is well covered.
Winter and spring wheat, durum wheat, winter barley, oats, rye and triticale: 0.25 litre/ha.
Spring barley: 0.125 litre/ha
In the event of crop failure, winter wheat may be redrilled immediately after normal cultivation and winter barley may be sown after ploughing. Fields must be ploughed to a depth of 15 cm and 20 weeks must elapse before sowing spring crops of wheat, barley, oilseed rape, peas, field beans, sugar beet, potatoes, carrots, edible brassicas or onions. After normal harvest autumn cereals can be drilled after ploughing. Thorough mixing of the soil must take place before drilling field beans, leaf brassicae or winter oilseed rape. For sugar beet seed crops and winter onions complete inversion of the furrow slice is essential.
Successive treatments of any products containing diflufenican can lead to soil buildup and inversion ploughing must precede sowing and following non-cereal crop. Even where ploughing occurs some crops e.g. onion, leek, other allium crops and clover may be damaged. As a precaution, users who rent out their land to growers should not use diflufenican containing products in successive years before renting out the land.
When herbicides of the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominant. A weed species is considered to be resistant if it survives a correctly timed application at the recommended rate. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural measures. Guidelines have been produced by the Weed Resistance Action Group and copies are available from HGCA, CPA, your distributor, crop advisor or manufacturer.
MIXING AND SPRAYING
Apply with a tractor mounted sprayer. Before spraying ensure the sprayer is clean and in good working order. Half fill the sprayer with clean water and begin to agitate. Add the required quantity of STRIDE DFF and complete filling. Continue to agitate during spraying. Apply in 200-300 litres/ha water as a medium spray (BCPC category). Increase the water volume where weed infestation is heavy or the crop cover is dense.
Complete coverage of weeds is essential.
Wash out the sprayer thoroughly after use using a recognised tank cleaner or wetting agent.
CLEANING OF TANK AND EMPTY PACKAGING
After using STRIDE DFF empty the tank completely and drain the whole system. Thoroughly wash inside the tank with a pressure hose. Quarter fill the tank with clean water and circulate through the pump, line, hoses and nozzles, then drain. Quarter fill the tank again, add a suitable detergent and circulate through the system for at least 15 minutes. Drain, remove filters and nozzles and clean separately. Rinse inside the tank thoroughly using a pressure hose and flush system with clean water. RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add the washings to the sprayer tank at the time of filling and dispose of container safely.
