BRIGHENTI, Alexandre M. et al. Chemical weed control in sucessive crops of corn and field bean. Planta daninha [online]. 1998, vol.16, n.2, pp. 109-116. ISSN 0100-8358. http://dx.doi.org/10.1590/S0100-83581998000200004.
This trial was carried out at the Sooretama Experimental Farm, in Linhares, State of Espírito Santo, Brazil, in order to evaluate the efficiency of herbicides on weed control in sucessive crops of corn and beans. The comercial mixture of atrazine plus metolachlor was more efficient to control weeds in corn (Zea mays) crop than atrazine and metolachlor applied alone. The comercial rate of 8,04 l ha-1 led to the highest yield of corn (7004,92 kg ha-1). The tank mixture of fomesafen plus sethoxydim was more efficient to control weeds in the field bean (Phaseolus vulgaris) crop than linuron and metolachlor applied alone. The tank mixture of 0,74 l ha-1 of fomesafen plus 0,74 l ha-1 of sethoxydim showed the highest yield of bean (1454,05 kg ha-1).
