The spot treatment rate for Amitrol 240 on non-crop land is incorrect in Table 7.2 on page 71 of the new nursery production guide.

The correct rates are:

• 165 mL in 10 L of water/100 m2 to control Canada thistle, dandelion, hoary cress, milkweed, poison ivy, sow thistle and toadflax.
• 460 mL in 10 L of water/100 m2 to control horsetail, leafy spurge, quackgrass and most other weeds.

Please update your guide accordingly.
