Plant development in soursob populations and some implications for control


, : Plant development in soursob populations and some implications for control. Proceedings of the Sixth Australian Weeds Conference, 1981 (Volume 1): 55

In pot trials, the time of emergence of soursob (Oxalis pes-caprae) extended over 4 wks. Emergence was delayed by up to 18 days by planting at a depth of 20 cm rather than at 5 cm and delays of 3 months were induced by withholding water. Late emerging plants could be affected by competition.
