Winning start to Argentine fruit fly controls
Argentine authorities are claiming a “significant advance” in results of an eradication programme in the north-east against Mediterranean fruit flies ( Ceratitis capitata) and South American flies ( Anastrepha fraterculus) on citrus crops. The national animal and plant health inspection service, the Senasa, has worked with farmers, applying Dow AgroSciences’ insecticide, spinosad, on over 16,000 ha in the region. The service chose the “bio-insecticide” for its low environmental toxicity, it says. Some 7,500 ha more are to be sprayed in two provinces this year, and a further 20,000 ha in 2012 in a “massive” bio-insecticide use programme, before the final phase in 2013. The monitoring stage of the eradication programme, “Procem Nea”, began in 2009 with the use of traps across over 56,000 ha. Quarantine areas were set up in 2009 and IPM systems were introduced two years’ before, aiming to cut chemical pesticide use by 80% ( Agrow No 570, p 17).
