% Aphid control
HALLMARK Zeon is highly active
against cereal aphids. Independent
work has demonstrated that
HALLMARK Zeon is more potent than
other pyrethroid products even against
resistant forms of grain aphids due to
its higher intrinsic activity.

DO GENERICS PERFORM DIFFERENTLY?
HALLMARK Zeon provides higher
levels of efficacy than generic
products due to its superior
microcapsule formulation and the
addition of titanium dioxide which
provides UV protection. This enables
HALLMARK Zeon to offer the best
chance of achieving high levels of
control.
