ACTARA contains 250 g/kg thiamethoxam formulated as a water dispersible granule. It
controls a range of aphids that commonly attack seed and ware potatoes including strains of
Myzus persicae resistant to organophosphate, carbamate and pyrethroid insecticides.
ACTARA belongs to the neonicotinoid class of chemicals. It has contact, stomach and systemic
properties. ACTARA applied as a foliar spray provides rapid knock down of aphids and
through its systemic activity long lasting (typically 2–3 weeks) efficacy against re-invasion of
aphids. ACTARA applied to the soil at planting as an in-furrow spray will provide protection
against aphid infestation during the early growth of the crop; typically for three to four
weeks after crop emergence.
ACTARA when applied as a foliar spray will reduce the transmission of potato viruses (e.g.
potato leaf roll virus and potato virus Y) by controlling the aphid vectors which spread
these viruses. The aphids controlled include: peach-potato aphid (Myzus persicae), potato
aphid (Macrosiphum euphorbiae), glasshouse and potato aphid (Aulacorthum solani) and
buckthorn-potato aphid (Aphis nasturtii). The use of ACTARA as an in-furrow treatment for
seed potatoes at planting will provide early protection against the establishment of aphids
which will also help in minimising the early transmission of virus diseases.
