The effect of Oxalis latifolia competition in maize.
The comparative effect of Oxalis latifolia in maize was investigated during 4 seasons at Cedara Research Station, near Pietermaritzburg, Natal. In each of the 4 seasons initial weed control was achieved on all plots using a mixture of atrazine at 1.125 kg/ha + terbuthylazine 1.125 kg + metolachlor 2.190 kg. This treatment controlled a wide spectrum of weeds, except O. latifolia which became the dominant species present. Maize grain yields, plant lodging counts and the incidence of Diplodia and Fusarium cob rots were not significantly affected by up to 329 O. latifolia plants/m2.
