Australia permitted emergency use for PIRIMOR® to combat Russian wheat aphid

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has issued an emergency use permit (PER82792) for the use of Syngenta’s PIRIMOR® (active ingredient: pirimicarb; rate: 200-250g/ha) to control Russian Wheat Aphid (RWA) in winter cereals. The permit is valid from 8 June 2016 until 30 June 2018.
 

The first case of RWA was identified in a wheat crop at Tarlee in South Australia’s Mid North in mid-May and infestations have now spread into Victoria.

 

PIRIMOR has a unique 3-way action that provides fast action and rapid knockdown against aphids:

 

Direct contact: PIRIMOR gives rapid knockdown of aphids. This is evident within hours under ideal conditions.

 

Fumigant action: PIRIMOR produces a powerful fumigant action after application which helps control aphids which may be hidden under leaves, inside the crop canopy and shielded from direct spray contact. Fumigant activity is most evident when applying pirimicarb in temperatures above 20°C.

 

Translaminar activity: PIRIMOR penetrates the upper sprayed side of leaves and moves to the underside of leaves. Any aphids sheltering on the back of leaves are controlled when feeding.

 

PIRIMOR is a specific aphicide which is IPM compatible. It has low risk to bees (application while bees are foraging should be avoided if possible) and other beneficial insects. This causes minimal disruption to natural predators which are important to naturally manage insect pest numbers in cereals.
