Pyrethrum flowers cover north-west Tasmanian coast with 2015 natural insecticide harvest set to be biggest ever

By Alex Blucher

Every summer, the rugged northern Tasmanian coastline is covered with white, as fields of pyrethrum, a perennial white daisy, come into bloom.

Botanical Resources Australia (BRA) is the world’s largest supplier of the natural insecticide made from the dried flower heads.

With a cracker season and new high yielding varieties, this year looks set to be the biggest pyrethrum harvest on record.

Field production and research manager, Tim Groom, says it’s a unique crop to grow.

“It’s one of the few natural insecticides that exist in nature and it’s certainly the biggest one in usage to control a variety of insects, including spiders,” he said.
