Agricultural Uses: May be applied to grass forage (pastures and rangeland) for the control of fire ants in Texas and other (refer to label) southern states. Use on grass forage (pastures and rangeland) in states other than those listed is unlawful.  See Outdoor Use table on container label for application directions. Do not bale and cut treated pastures and rangelands for 7 days following application. These cutting and baling hay restrictions for pasture and rangeland do not apply when the treated pasture and rangeland is used solely to support COMPANION ANIMALS (e.g., horses, llamas, etc.). Companion animals grazed on treated areas cannot be used for food or feed. Amdro®Pro may be used on uncultivated, agricultural, non-food crop and non-agricultural land.  Can be used in pineapples and bait stations for numerous tropical fruit and nut crops.

Mixing with other products: approved to mix with Extinguish®; will work to speed activity of other slow-acting products, but mixing is not supported by company. Do not mix with other products if prohibited on other labels.

General Comments: Amdro® Pro is a reliable, inexpensive product and one of only two baits labeled for use on grazed or hayed land. Other than Advion®, it is the fastest-acting treatment available. Some poor performance of the product has been noted in very hot, dry conditions.

Because of the constantly changing availability of fire ant insecticides, it is virtually impossible to include every product on the market.
