Formatted Abstract/Summary
This study quantifies the combined effect
of competitive pasture plants with biological control
agents upon parthenium weed growth, first under
shade-house then under field conditions at two locations
in Central Queensland (Monto and Injune). The
glasshouse study showed that the competitive ability
of two test species (viz. bull Mitchell grass, Astrebla
squarrosa
C.E.Hubb. and butterfly pea, Clitoria ternatea
L.) were significantly increased in the presence of
the biological control agent Zygogramma bicolorata
Pallister. In the field trial at Injune competitive plants
were shown to suppress the growth of parthenium
weed by 18–51% in the absence of biological control
agents or by 60–86% in the presence of biological
control agents. In addition, the presence of the biological
control agents increased the productivity of the
test plants by 6–21%. In the field trial at Monto two
competitive plants (butterfly pea and buffel grass) were
shown to suppress the growth of parthenium weed
by around 33 and 50%, respectively, in the absence
of biological control agents or by 62 and 69% in the
presence of biological control agents. In addition, the
presence of the biological control agents increased the
productivity of the test plants by 15–30%. The early
indications are that the use of competitive plants in
the field where biological control agents have been
released will increase their effectiveness and provide
a source of fodder for grazing animals.
