In addition to the changes, the resolution determines that package inserts and labels shall be revisited to include information on the use of drift reduction technology in the following cases:

• It is mandatory to use 50% drift reduction technology for doses above 1.800g/ha in coastal, stationary, semi-stationary, and tractor applications; and
• obligation to use 50% drift reduction technology and five-meter boundary for doses above 3,700g/ha in the same circumstances.
