Laser (Trifolium resupinatum var. majus) is a soft seeded Persian Clover with a semi erect to erect growth habit that demonstrates late season maturity. This late maturity makes Laser well suited to areas with a long growing season. Laser produces large numbers of thin walled, hollowed stems, which contribute to the erect and bushy appearance. It is also well adapted to various soil types, tolerant to waterlogging and mild soil salinity. Laser was developed as a superior replacement for Maral providing improved herbage production and Rust resistance. Laser is very palatable, highly digestible (16-24% crude protein) and is well suited to multiple hay cuts, grazing or silage production and can be successfully used in pasture mixes with ryegrass or oats to increase winter production. Laser Persian Clover is an effective disease break in cropping rotation and has the ability to fix high levels of soil nitrogen. Laser Persian Clover will also assist in management of problem weeds including those that are herbicide resistant.
Laser demonstrates late maturity, flowering approximately 155-176 days after sowing. As the flowering habit is indeterminate flowering times can vary depending on the season.
Persian Clovers are susceptible to attack from Lucerne Flea (Sminthurus viridis) and Red Legged Earth Mite (Halotydens destructor). Control measures will need to take place as required.

- Shows good early vigour
- Offers excellent winter and early spring production
- Adapted to a large range of soil types, especially lighter soils
- Suitable for grazing, fodder, green manure and High Density Legume mixes
- Excellent pioneering plant, especially on acid soil
- Laser is well adapted to various soil types, tolerating both waterlogging and mild soil salinity. This allows it to be used in a variety of regions throughout Australia
- Laser is a large improvement over Shaftal, resulting in higher herbage production and rust resistance
Laser is resistant to Clover Scorch (Kabatiella caulivora) and has low resistance to Rust (Uromyces trifolii-repentis) on stems and leaves.
Laser is a very soft seeded variety and will require re-sowing. It is recommended that Laser only be used as a one year rotational crop as Rust (Uromyces trifoliirepentis) can cause losses if consecutive crops are produced. Laser is well suited to hay and silage but not tolerant to heavy grazing and should be treated as a fodder crop and grazed rotationally.
