ALBUS LUPINS HARD TO RESIST
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office"
Andromeda albus lupin, released last year, boasts improved resistance to
anthracnose and tolerance to most herbicides.
A Grains Research and Development Corporation (GRDC) supported project has
assessed the herbicide tolerance of Andromeda.
On average, WA growers annually deliver 700,000 tonnes of all lupin types.
Albus lupin is projected to have potential across 50,000 hectares in WA.
Production peaked at 30,000 hectares in 1995, before anthracnose arrived.
GRDC supported Department of Agriculture and Food researcher,
Dr Harmohinder Dhammu said Andromeda had good tolerance to herbicides
commonly used on lupins.
Andromeda showed better tolerance to metribuzin and its mixtures with other
herbicides than the older albus lupin variety, Kiev mutant.
However, applying metribuzin at 112 grams of the active ingredient per
hectare, caused moderate to severe leaf burning in both varieties, resulting
in a 15 35 per cent biomass reduction at flowering.
Increasing metribuzin application rates to 187 grams per hectare intensified
leaf burning symptoms and drastically reduced Kiev mutant yields.
The maximum metribuzin rate registered for lupins is 112 grams per hectare.
Andromeda has proved extremely popular and the Council of Grain Grower
Organisations sold out of this years seed in December 2005.
Growers keen to grow it in 2007 should place their orders soon.
