The objective of this
study was to determine the effect of several management
strategies on the populations of these species. A ten-year-old
banana plantation was chosen for evaluation with the
following treatments: T1 = untreated control; T2= physical
control, T3= successive sprays with glyphosate, T4=
successive sprays with paraquat, T5= successive sprays with
gluphosinate and T6= mixed control based on weed sampling.
Populations of P. zizanoides in rows were reduced 89, 93, 79
and 68% for T3,T4, T5, T6 respectively compared with T1. In
the area next to the banana plant, populations of P.
conjugatum were reduced by 78, 91, 95, 99 and 75% for T2,
T3, T4, T5 and T6 respectively (Duncan; p< 0.05). The results
indicate that treatments with herbicides and mixed control
reduce the populations of these species, while populations of
the untreated and physical control plots remained constant in
time.
