Herbicide
Leystar is a selective herbicide for use in new sown leys, grass for seed and maize.

• 3 actives delivering effective translocation and wide spectrum of weed control
• Controls key weeds such as chickweed, fat-hen (2 true leaves), mayweeds, seedling docks and thistles
• Handy small pack which treats 2 ha / 5 acres at 1.0 L/ha
• Good grass safety
Benefits
Grassland
Best use advice - Grass
• For best results apply to weeds which are small and actively growing
• Broad-leaved weeds not present at application will not be controlled
• Allow an interval of 4 weeks after application before cutting grass to optimise the effect of the herbicide
• Do not roll or harrow grass for 10 days before or 7 days after application
• Do not spray where clover or other legumes are a valuable constituent of the sward
• Grass seed can be stitched in 1 month after application
• Clover can be stitched in 3 months after application
• Grazing can resume just 7 days after application
– This may need to be longer if foliage of poisonous weeds such as ragwort is present
• To avoid subsequent injury to crops other than grassland and cereals, all spraying equipment must be thoroughly cleaned using All Clear Extra spray cleaner
Maize
Best use advice - Maize
• Apply when maize is between 3-6 leaf stage, and before the crop is over 20 cm tall. Do not apply once the buttress roots have started to develop on the first node.
• Crops that can be sown in the year of treatment with Leystar to forage maize include:
– Cereals, oilseed rape, grass and vegetable brassicas as transplants
• To protect surface water, do not apply to maize before 10th April
• To avoid subsequent injury to crops other than grassland and cereals, all spraying equipment must be thoroughly cleaned using All Clear Extra spray cleaner
• Tank mixes are not supported on maize
Cereals and Cereals Undersown With Grass
• Leystar can be applied in the spring on all varieties of winter and spring cereal
• Applications should be made from 1st February once the crop has reached 3 leaves
