| É importante avaliar a tolerância de variedade de mandioca a novas alternativas de controle químico, com o intuito de ampliar as opções disponíveis. Este trabalho teve como objetivo avaliar a seletividade de herbicidas aplicados em pré-emergência, para duas importantes variedades de mandioca cultivadas no Estado do Paraná. Os herbicidas e respectivas doses (g i.a. ha-1) avaliadas foram: diuron (400 e 800), metribuzin (360 e 720), isoxaflutole (60), atrazine (720), S-metolachlor (1.920) e as misturas ametryn + clomazone (1.350+1.900), ametryn+trifluralin (1.500+1.350), isoxaflutole+metribuzin (60+320), isoxaflutole+diuron (60+400), combinados com uso de uma testemunha dupla adjacente a cada tratamento. Os cultivares utilizados neste trabalho foram Fécula... |

| Tank mixtures among herbicides of different action mechanisms might increase weed control spectrum and may be an important strategy for preventing the development of resistance in RR soybean. However, little is known about the effects of these herbicide combinations on soybean plants. Hence, two experiments were carried out aiming at evaluating the selectivity of glyphosate mixtures with other active ingredients applied in postemergence to RR soybean. The first application was carried out at V1 to V2 soybean stage and the second at V3 to V4 (15 days after the first one). For experiment I, treatments (rates in g ha-1) evaluated were composed by two sequential applications: the first one with glyphosate (720) in tank mixtures with cloransulam (30.24),... |
