Grape moth controls bear fruit in Argentina
The extent of European grapevine moth ( Lobesia botrana) infestations in Argentina has dropped since last year due to growers carrying out official controls, official monitors say. Traps have captured fewer moths in the Mendosa region for this growing season, while spread across the rest of the country has been avoided, the national animal and plant health inspection service, the Senasa, says. In one region, no new incidences of the pest have been found. In 2011/12, some 2,800 smallholders received around 19,800 litres of pesticides to be applied on up to 18,000 ha, while pheromones were used on 1,600 ha. Inspections have shown that 65% of chemical applications and 90% of “cultural control” methods were correctly carried out, the Senasa says. More pesticides are being distributed as part of the programme to grapevine growers with less than 25 ha.
