Visando o controle do ataque do caruncho, Sitophilus oryzae (L, 1763) em trigo armazenado, aplicou-se, em mistura direta com os grãos, 7,5; 10; 15 e 20g i.a. de Diclorvos (DDVP-500) e 12g i.a de Diclorvos (DDVP-1000) por tonelada. Utilizando-se um calador retirou-se 0,5 litros de grãos por parcela, em cinco ocasiões, sendo uma antes e quatro após a aplicação dos produtos, para avaliação do número de insetos vivos. Todas as doses e produtos controlaram eficientemente o caruncho no trigo armazenado, com exceção da dose de 7,5g i.a./t de grãos, de Diclorvos, que não atingiu 90% de controle em todas as datas e, pêlos níveis de infestação ocorrentes durante o teste não deve ser recomendada. |
