Leystar

Product information

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

Leystar is much valued by grassland farmers for its wide weed spectrum including chickweed, seedling docks and thistles and good grass safety when used on new sown leys. Leystar is also for use in maize and grass grown for seed.

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

– 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

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
