A selective pre-plant pre-emergence soil incorporated herbicide for the long-lasting control of certain varieties of germinating annual grasses and broadleaf weeds in agricultural and horticultural crops.

Beware: Apply this product carefully. Spray drift may cause serious damage to desirable plants.

DIRECTIONS FOR USE
Trifluralin Herbicide is a selective pre-plant soil incorporated herbicide for the long lasting control of certain varieties of germinating annual grasses and broadleaf weeds in agricultural and horticultural crops as show in the Application Table. Trifluralin Herbicide controls weeds as they germinate, but will not control established weeds. The active ingredient of Trifluralin Herbicide is broken down by ultra violet light, so it must be incorporated into the soil immediately after application.

CROP SAFETY
Trifluralin Herbicide applied according to directions and under normal growing conditions will not harm the treated crop, however seedling disease, cold weather, deep planting, excessive moisture, high salt concentration, or drought may weaken crop seedlings and increase the possibility of crop damage. Under these conditions, delayed crop development, or reduced yields may result. Sowing linseed deeper than 3cm may result in some linseed stand reduction. Under prolonged dry conditions, or prolonged cold wet conditions, certain crops are susceptible to injury when planted in soil previously treated with Trifluralin Herbicide. To avoid such injury, it is not advisable to plant sensitive grasses, such as ryegrass or wheat, for 12 months following Trifluralin Herbicide application.

APPLICATION AND INCORPORATION
The soil should be flat, free of trash and large clods and not excessively wet. Foreign material such as plant residues or stones on or in the soil can reduce herbicide effectiveness. Trifluralin Herbicide should be evenly applied to the soil surface in a spray volume of 100-400 litres of water per hectare, at pressures of 200-300kPa. Avoid boom overlaps to minimise the risk of crop injury. Thorough incorporation is essential for weed control. Incorporation can be carried out as part of the normal seed bed preparation providing that the implements are used as per the following recommendations:
1. Power driven rotary implements set to cut to depth of 5-10 cm. Lely Roterra may be used only if the spray boom is mounted on the implement.
2. Tandem discs set to cut 8-15cm deep and operated at a speed of not less than 6- 10kg/h.
3. Heavy spike or diamond harrows or dutch harrows operated at 10-13km/h. Trailing harrows must be weighted 20-30kg per section. Chain harrows are not recommended.

A minimum of two workings in different directions (ie at 90o to each other) is essential (except with rotary hoe) for thorough incorporation. The soil surface should be left relatively clod free, i.e. max. clod size 4cm diam. Shallow cultivation during the growth of the crop will not reduce weed control. Soil organic matter warning: Do not use on soils with 9% or higher organic matter content, or peat type soils. Soil texture is given only as an indicator to organic matter level. If in doubt, contact your representative of ADAMA New Zealand Limited.

MIXING
Partially fill the spray tank and add the correct amount of Trifluralin Herbicide. Agitate thoroughly while filling and spraying. After a stoppage and before recommencing spraying the spray solution must be vigorously agitated to ensure it is well mixed.
