As pragas das hortaliças: seu controle e o selo verde

Abstract: O plantio de hortaliças no Brasil ocupa uma área aproximada de 326 mil hectares. Todas as hortaliças são exigentes na aplicação de defensivos, o que cria não só riscos de intoxicação de agricultores, mas também de consumidores, devido aos resíduos tóxicos nos alimentos. Isso acontece porque na maioria dos casos há poucas opções de controle de pragas além do controle químico. O controle biológico é pouco explorado porque, em plantas de ciclo curto, as chances de que o predador ou parasitóide atuem com eficiênci… Show more

“…O controle químico das pragas tem sido o mais disponível ao tomaticultor e é muito utilizado no controle das brocas e traças dos frutos do tomateiro (França et al 1983, Haji et al 1986. Nakano (1999) citou diversas razões pela qual o controle químico tem sido predominante em hortaliças, entre elas, a especificidade dos agentes de controle biológico e o ciclo curto das culturas, que impedem o estabelecimento de predadores e parasitóides.…”
