Azur top 325 SC is a broad-spectrum fungicide containing axoystrobin and difenoconazole.
It has systemic, translaminar and protectant properties, giving broad-spectrum contral of diseases of horticultural crops.
AZUR TOP 325 SC contains a mixture of azoxystrobin, which is derived from natural
strobilurins found in mushrooms, and the triazole fungicide difenoconazole. It
inhibits fungal respiration and growth. It is best used as a protectant spray
or during the early stages of disease development.

AZUR TOP 325 SC is formulated as an easy to handle fine
suspension concentrate, containing 200 g/l azoxystrobin and 125 g/l
difenoconazole. It mixes well with a wide range of other fungicides and
Spectrum of activity
AZUR TOP 325 SC controls early blight, Alternaria spp, in potatoes and other crops. It can also control
Ascochyta, Colletotrichum, Cercospora, powdery mildew and Alternaria in a range
of other crops.
Azoxystrobin inhibits mitochondrial
respiration in fungi by preventing electron transfer between cytochromes b and
c. It acts preventatively, inhibiting spore formation in the early stages of
disease development. It also has a curative effect against rusts. Azoxystrobin has limited
systemic movement, redistributing to leaves emerging at the time of treatment.
It distributes uniformly within sprayed leaves and has translaminar movement,
penetrating through the leaf to control disease developing on its underside.
Difenoconazole inhibits synthesis of the
sterol components of the fungal cell wall, which leads to malformation and
rapid death of the pathogens.
These two unrelated modes of action confer
robustness to the fungicide by extending the range and efficacy of control, and
giving the product much greater resilience to the development of resistance by
