A pot experiment was carried out under controlled
conditions to evaluate the residual effects of different doses of
atrazinealachlor and foramsulfuron used in corn fields on the
growth and physiology of rapeseed (Brassica napus L.). A splitplot
experiment in CRD with 4 replications was used. The main plots
consisted of herbicide type (atrazinealachlor mixture and
foramsulfuron) and the subplots were different residual doses of the
herbicides (0, 1, 5, 10, 20, 40, 50 and 100). 7 cm
diameter pots were filled with a virgin soil and seeds of rapeseed cv.
Hayola were planted in them. The pots were kept under controlled
conditions for 8 weeks after germination. At harvest, the growth
parameters and the chlorophyll contents of the leaves were
determined. The results showed that the growth of rapeseed plants
was completely prevented at the highest residual doses of the
herbicides (50 and 100 ). The growth parameters of rapeseed plants
were affected by all doses of both types of the herbicide as compared
to the controls. The residual effects of atrazinealachlor mixture in
reducing the growth parameters of rapeseed were more pronounced
as compared to the residual effects of foramsulfuron alone.
