Critical Comments
1. Use only a spray-on applicator gun recommended by Pharmsmart.
2. Ensure the applicator gun is clean.
3. Calibrate applicator gun using an accurate volume measure.
4. Ensure all areas to be protected are treated.
5. When preventing body strike ensure bands overlap along the midline (Diagram 1).
6. This product is not ideal for treating existing strikes. Treated larvae may take three to four days to die. Use a product registered as a dressing for existing strikes (e.g. Extinosad™ Aerosol, Extinosad™ Eliminator).
7. Should not be mixed with any other product.
8. Should not be applied during gusty or windy weather as spray drift will reduce the period of protection.
9. Heavy rain following the application of this product could diminish the period of protection.
10. Vetrazin™ Spray-On is coloured for band identification. This scourable dye will disappear shortly after treatment
