Imported Fire Ant Treatments

Approved Imported Fire Ant (IFA)Treatments for Nursery Stock, Balled or in Containers:

Method B - Drenching

Equipment -

  1. A large-capacity bulk mixing tank, either pressurized or gravity flow, for mixing and holding the insecticide solution.
  2. Properly equipped hoses and watering nozzles that can be attached to the mixing tank and used to thoroughly saturate the plant balls or containers with the insecticide solution.

For Plants in Containers -

Procedure - Apply either a bifenthrin, chlorpyrifos, or diazinon solution to the point of saturation one time only. The volume of the treating solution must be at least 1/5 the volume of the container.

Insecticides and Dosages -

Insecticide     Dosage

   
chlorpyrifos (4EC)     4 fl. oz. 4EC per 100 gal. water
chlorpyrifos (2EC)     8 fl. oz. 2EC per 100 gal. water
diazinon (AG-500 or 50 WP) *     1 pint AG-500 or 1 lb 50WP per 100 gal water
bifenthrin (flowable) * *     25 parts per million (p/m) See table below.
Diazinon is registered under FIFRA, sec. 24(c), Special Local Needs, in some States. Check with your State Regulatory official before using.

* *Dose rate for bifenthrin is 25 p/m based on dry weight bulk density of the potting media. Use this link to access information regarding bulk density determinations.


Potting media bulk density* (lb./yd.³)     Oz. Talstar Flowable/100 gal. water

   
200     2.4
400     4.8
600     7.2
800     9.6
1,000     12.0
1,200     14.4
1,400     16.8

Exposure Period - Plants are certifiable immediately upon completion of the treatment.

Certification Periods -


Insecticide     Certification Period
       
chlorpyrifos     30 days
diazinon     10 days
bifenthrin     180 days

For Balled and Burlapped (B&B) Plants -

Procedures - Apply a chlorpyrifos solution (see table below) as a substitute for plain water to the plants during the routine watering activities after the harvest but prior to shipment. Do not remove burlap from plants prior to treatment. Treat plants singly or in groups with the chlorpyrifos solution to the point of runoff on a twice daily schedule for three consecutive days.

This treatment should be carried out in a well ventilated place normally used to maintain plants prior to shipment. The treatment location should be covered, if possible. The treatment will be enhanced by adding any agricultural wetting agent or surfactant to the chlorpyrifos solution.

Insecticide and Dosages -

Insecticide     Dosage

   
chlorpyrifos (4EC)     4 fl. oz. 4EC per 100 gal. water
chlorpyrifos (2EC)     8 fl. oz. 2EC per 100 gal. water

Certification Period - 30 days.
