A foliar applied herbicide for the control of annual and perennial grasses and broad-leaved weeds before sowing or planting all crops. For use pre-harvest in cereals and certain other crops, destruction of grassland, and in stubbles, orchards, green cover on land not being used for production, forestry and noncrop areas.

Tractor Mounted Applicators
Conventional Hydraulic Sprayers:
1. Sprayer and Nozzle Selection:
All machines should be capable of applying accurately 80-250 L/ha, as a
'MEDIUM' or 'COARSE' quality spray - (BCPC definition) within a pressure range of 1.5-2.5 bars using 80 or 110 degree nozzles. For application preharvest of crops it is essential to use a sprayer whose boom may be raised to the correct height.
2. Water Volume:
For general use 200-250 L/ha is the preferred volume range. For specific uses, volumes may be reduced to 80-120 L/ha by selecting low volume hydraulic nozzles, and adjusting pressure of application and tractor forward speed.
3. Spray Pressure:
Pressures must be related to tractor forward speed, desired water volume and nozzle type. A range of 1.5 - 2.5 bars must be used to ensure optimum results with minimum risk of drift.
4. Tractor Forward Speed:
Speed of travel must be related to nozzle output characteristics. The typical range is from 4-9 kph. The slower speeds should be selected for applications pre-harvest of crops and where soil conditions could cause excessive boom bounce and yaw at faster speeds.
5. Recommended Nozzle Type, Pressure, Volumes and Tractor Speeds for the Application of 80-120 L/ha: 80 or 110 degree nozzles able to apply the required volume at pressures between 1.5 -2.5 bars at between 4-9 kph are recommended. Examples of these nozzles are available in a separate handbook.
6. Filling the Sprayer:
Half fill the spray tank with water and start agitation. Add recommended quantity of SNAPPER herbicide, top-up tank with water to required level.
To avoid foaming do not use top tank agitation. Use of a defoamer may be necessary.
7. Calibration:
Before using a sprayer and, especially, after nozzles have been changed, it is essential to calibrate the sprayer by checking the output of at least one nozzle for each separate boom section of the sprayer.

Operation in the Field:
Check the following before starting to spray:
- That the nozzles are aligned evenly at the correct angle to the direction of travel.
- That the boom is level over its width.
- The boom height permits the correct pattern of spray overlap on the target weeds.
