Brazil tomato growers cut agchem use by half

Tomato growers in a Brazilian region have cut their use of pesticides by half in less than four years. Some growers in Santa Catarina have taken part in an IPM project, which was set up in 2005 and gained Ministry of Agriculture backing last year, the newswire, Agrolink, reports. Monitoring of traps is carried out and only when inspections show 20 pests are present are pesticides applied, except in the case of the tomato fruitworm borer ( Helicoverpa zea) , the main pest. The presence of just one of those requires a pesticide application. The presence of tomato fruitworms could result in loss of 80% of the crop, the Brazilian agricultural research corporation, the Embrapa, says.
