Descripon: SARDI-Grazer is the most grazing tolerant lucerne variety currently available in Australia. It is a new winter acve variety developed by SARDI and the Department of Agriculture and Food, Western Australia with funding from the GRDC. SARDI-Grazer was developed primarily for use in cropping rotaons, where large paddocks limit the use of rotaonal grazing. It delivers superior persistence where uneven grazing causes areas of the paddock to be heavily grazed before others can be properly ulised. It is also useful in permanent pastures in the medium to high rainfall areas of Australia where long periods of connuous grazing (over 4 weeks) by sheep or cale is common pracce. Pest Resistance: SARDI-Grazer is highly resistant (HR) to Spoed Alfalfa Aphid (Therioaphis trifolii) and Blue-Green Alphid (Acyrthosiphon kondoi). As with other lucerne variees, SARDI-Grazer is suscepble to damage from Red Legged Earth Mite (Halotydens destructor) and control measures need to take place prior to seeding or soon aſter germinaon.

Description:SARDI-Grazer is the most grazing tolerant lucerne variety currently
available in Australia. It is a newwinter active variety developed by
SARDI and the Department of Agriculture and Food, Western Australia
with funding from theGRDC. SARDI-Grazerwas developed primarily
for use in cropping rotations,where large paddocks limit the use of
rotational grazing. It delivers superior persistence where uneven
grazing causes areas of the paddock to be heavily grazed before others
canbeproperlyutilised.
It is also useful in permanent pastures in the medium to high rainfall areas

Pest Resistance: SARDI-Grazer is highly resistant (HR) to Spotted Alfalfa Aphid
