Question: 

What do I do if a PHI note contains information with different PHI requirements?

Answer:

If the PHI note contains information describing different application scenarios, input the PHI that matches your specific use.  

For example, if the PHI note says "At 3 fl oz/A, PHI = 1 day; At 6 fl oz/A, PHI = 3 days", input the PHI value that matches your application rate.
