PRODUCT GUIDE
What is Brodal Options?
Brodal Options is an advanced formulation of Brodal
Outstanding crop safety
that provides improved efficacy on broadleaf weeds,
while retaining the same residual control and
crop safety.
Brodal Options is the culmination of many years of
development by Bayer CropScience chemists and field
scientists in the quest to provide better products for
Australian farmers.
Bayer CropScience has found that Brodal Options
formulation produces a slight increase in crop effect,
but still offers a significantly higher level of crop safety
than a competitive product.
Graph 2: Field pea tolerance trial
(Mallala, 2001)
The optimum application window for Brodal
Options in lentils is between the appearance of
the 3rd and 6th leaf nodes. This early timing
maximises weed control (contact and residual),
while minimising any signs of crop phytotoxicity.

Trial results show that the new Brodal Options
Brodal Options should be applied
after emergence for optimal weed control.
The crop should be at least 3-node before the
application of the herbicide (Diagram 1),
which can be applied up to the flowering
stage. However, for optimal weed control,
Brodal Options should be applied early:
approximately 4–6 weeks post-sowing, when
weeds are small and actively growing.
% crop effect
Brodal has long been recognised as the
leading herbicide for the control of
broadleaf weeds in lupin, field pea and
lentil crops. Brodal’s key strengths are its
high levels of cruciferous weed control,
residual activity and crop safety.
