Example - Type 12, 15, 17 and 18 - Item 14 (Ag) - Scenario 5

Scenario 5: Variation to application rate of a product in a non-food producing situation


An application is made to increase the application rate for a herbicide used to control broadleaf weeds in non-crop areas from 0.5–1 L/ha to 0.5–2.5 L/ha in order to change a claim of weed suppression to weed control. The applicant has only provided efficacy data to support the application in relation to the new claim. The current label has a grazing WHP of do not graze treated areas and the holder does not propose to change this.

Application type

This application is considered under a technical variation (Item 14) as evidence is needed to demonstrate that product’s capacity to meet the safety (Agvet Code, s 5A) criterion will not be affected by the increased application rate.
