Abstract	O experimento foi conduzido na Fazenda Escola da UEPG, em Ponta Grossa-PR, em Latossolo Vermelho Escuro de textura media argilosa, com o objetivo de verificar a praticabilidade e a eficiencia agronomica dos herbicidas metolachlor e metribuzin + metolachlor no controle de plantas daninhas na cultura da batata. O delineamento experimental foi de blocos ao acaso com nove tratamentos e quatro repeticoes, quais sejam: metolachlor (1,92; 2,88 e 3,84 kg i.a./ha); metribuzin + metolachlor (0,24 + 1,68; 0,36 + 2,52 e 0,48 + 3,36 kg i.a./ha); metribuzin (0,48 kg i.a./ha); testemunha capinada e testemunha sem capina. O plantio foi realizado em outubro/95 utilizando-se a cultivar Elvira, no espacamento 0,70 x 0,35 m. As plantas daninhas predominantes foram Brachiaria plantaginea (capim-papua), Digitaria horizontalis (capim-milha) e Galinsoga parviflora (fazendeiro). As avaliacoes foram efetuadas aos 15, 30 e 45 dias apos a aplicacao dos tratamentos onde verificou-se que foram eficientes os seguintes herbicidas: metolachlor no controle sobre capim-papua e capim-milha nas doses de 2,88 e 3,84 kg i.a./ha; a mistura metribuzin + metolachlor no controle sobre capim-papua e capim-milha nas doses 0,36 + 2,52 e 0,48 + 3,36 kg i.a./ha; metolachlor (1,92; 2,88 e 3,84 kg i.a./ha) e metribuzin + metolachlor (0,24 + 1,68; 0,36 + 2,52 e 0,48 + 3,36 kg i.a./ha) no controle sobre fazendeiro. Nao foram observados efeitos fitotoxicos dos produtos sobre as plantas de batata.
