• Environment: Toxic to aquatic organisms and non-target terrestrial plants. DO NOT discharge effluent containing this
product into sewer systems, lakes, streams, ponds, estuaries, oceans or other water. Dispose of all excess treated seed.
Left over seed may be double-sown around the headland or buried away from water sources in accordance with local
requirements. DO NOT leave exposed treated seed on soil surface. Any spilled or exposed seeds must be incorporated
into the soil or otherwise cleaned-up from the soil surface. The use of this chemical may result in contamination of
groundwater particularly in areas where soils are permeable (e.g. sandy soil) and/or depth to the water is shallow.
Hazard Rating:
None listed.

• Container sizes - 10, 100, 1000 L
Crops, Diseases, Insects and Rates:

Under high insect pressure, a foliar insecticide may also be required. Monitor crop regularly for insect infestation
levels.
3
In areas where flea beetle populations are often high, use the higher rates.
Application Information:
For use in commercial seed treaters only. Seed treatment must be thoroughly agitated to ensure uniform mixing of product
prior to and during application. DO NOT apply direct heat to container. These products DO NOT contain colourant. A blue
colourant must be added when products are applied to oilseeds. Treatment of highly mechanically scarred or damaged
seed or seed known to be of low vigour and poor quality may result in reduced germination and/or reduction of seed and
seedling vigour.
How it Works:
Imidacloprid is a chloronicotinyl insecticide with systemic activity. For more information refer to “Insecticide Groups
Based on Modes of Action”on page 624. Carbathiin is a carboximide fungicide with systemic activity and thiram is a
dithiocarbamate fungicide with contact activity. For more information refer to “Fungicide Modes of Action”on page 435.
