DOSE (L/HA)
MAXIMUM NUMBER OF APPLICATIONS
BROTH VOLUME (L/HA)
Apply in 200 – 400 L water/ha.
APPLICATION TIME
For all cereals apply in the spring before 1st node detectable stages (GS 31).
- WINTER WHEAT, BARLEY, OATS AND RYE: Spray in the spring from the leaf sheath erect stage.
- SPRING WHEAT, BARLEY AND RYE: Spray after the crop has developed five fully expanded leaves.
- SPRING OATS: Spray after the crop has developed one fully expanded leaf.
Application under very hot conditions at later timings can cause ear damage if the crop comes under stress after application.
Barley is particularly subject to malformation and particular attention must be paid to the correct growth stage if this crop is intended for malting.
All varieties of winter and spring wheat, barley, oats and rye may be treated.
UNDERSOWN CEREALS
Do not apply to cereals undersown with lucerne, peas or safoin.
Red Clover
- Application rate: 1.4 L product/ha
- Maximum total dose: 1.4 L product/ha
Application should be made when the red clover has at least two trifoliate leaves, and the cereal crop is at the correct growth stage, as listed above.
Only apply if the weeds canopy is dense and covers most of the clover seedlings. Some damage to red clover must be expected, but this will normally be out-grown. Do not apply if white clover is present.
Grasses
- Application rate: 2.7 L product/ha
- Maximum total dose: 2.7 L product/ha
Application should be made when the grasses have begun to tiller, and the cereal crop is at the correct growth stage, as listed above.
Apply in 200 – 400 L water/ha.
Grassland
usage instructions
Use on established grassland and leys no less than 1 year old. Apply HAKSAR 500 SL in spring and summer when growing conditions are favorable. Spray grass for hay or silage 3-4 weeks before cutting. Clover may be checked but recovers by the following Spring. Follow-up applications may also be needed where new seedling weeds appear. An interval of 4-6 weeks should elapse between successive applications if weeds persist.
A top dressing ten days before treatment is recommended to assist kill of weeds and subsequent recovery of the sward. Annual weed species will be best controlled if spraying is done while the majority of weeds are seedlings. Perennial weeds should be sprayed during their period of maximum growth, usually when the flower buds are beginning to form. The response of perennial weeds to treatments are often variable with only the aerial parts killed, though often suppression will occur. The recovery of the weeds will be reduced if the grass is growing vigorously at the time of treatment.
