Sprayer Cleaning:
Thifensulfuron/tribenuron can cause severe injury to sensitive crops at very low concentrations. Sprayers used to spray
Thifensulfuron/tribenuron should be drained and flushed out immediately after use.
Refer to ‘Method A’ in the general section on sprayer cleaning on page 9 and 10. If mixing with another pesticide with
different cleaning measures, those measures should be integrated into ‘Method A’ (e.g. addition of detergent).
