Crops, Rates and Staging:
The maximum safe rates for various crops are given below. Higher rates used for harder to control weeds (see “Weeds,
Rates and Staging”) may cause crop injury. Application rates for individual products may vary from those listed. Refer to the
label for product specific use rates. Rates greater than those for harder to control weeds may cause crop injury. When tank
mixing, always check the tank mix partner recommendations for additional staging restrictions.
