General Instructions General Instructions1
FASTAC Duo is a contact and residual insecticide. It can be used as a protective treatment when applied at regular intervals or as a knockdown treatment to control existing infestations.
The product can be applied mixed either with water carrier or oil based bulking agents such as D-C-TRON+ Cotton Spray Oil or compatible ULV products.

Dilute spraying
- Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the crop being sprayed.
- Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off.
- The required water volume may be determined by applying different test volumes using different settings on the sprayer, from industry guidelines or expert advice.
- Add the amount of product specified in the Directions for Use table for each 100 L of water. Spray to the point of run-off.
- The required dilute spray volume will change and the sprayer set up and operation may also need to be changed as the crop grows.
Concentrate spraying
- Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the crop being sprayed.
- Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.
- Determine an appropriate dilute spray volume (See Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate.
- The mixing rate for concentrate spraying can then be calculated in the following way:
1. Dilute spray volume as determined above: For example 1500 L/ha
2. Your chosen concentrate spray volume: For example 500 L/ha
3. The concentration factor in this example is: 3 X (i.e. 1500 L ÷ 500 L = 3)
4. If the dilute label rate is 100 g/100 L, then the concentrate rate becomes 3 x 100, that is 300 g/ 100 L of concentrate spray.
- The chosen spray volume, amount of product per 100 L of water, and the sprayer set up and operation may need to be changed as the crop grows.
- For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.
For concentrate application, use a spray volume of at least 200 litres per hectare.
For dilute application, apply to run-off. See Dilute spraying above.
APPLICATION - Crops other than grapevines, pome and stone fruit
Low Volume and High Volume by ground rig or aircraft when FASTAC Duo is applied with water carrier.
FASTAC Duo can be applied by ground or aircraft with a water carrier. Thorough coverage is essential to ensure adequate control. Always apply with a non-ionic surfactant unless detailed on the label of a tank mix partner. Apply during the cooler parts of the day or night.
Ground application - water carrier
For low volume spraying of field crops with ground rigs, use a total volume of 50-200 L/ha except for sweet corn, tomatoes and tobacco where higher volumes should be used. Drop arms should be used on ground rigs in row crops taller than 30 cm (0.3 m). The application should be made as a fine spray, preferably using hollow cone nozzles, unless otherwise directed in the Critical Comments.
Aerial application - water carrier
Do NOT apply to trellis tomatoes by aircraft. Use a minimum spray volume of 20 L/ha. For spring/early summer application to cereals, linola, canola, rice and to other dense crops, apply in a total spray volume of 30 to 35 L/ha. If possible, spray in a crosswind. Avoid spraying in calm conditions or when wind is light and variable in direction. Apply as a spray of 100-150 microns VMD. Ultra Low Volume (ULV) application by aircraft
FASTAC Duo, mixed with D-C-TRON Cotton Spray Oil, D-C-TRATE, Synertrol+, Ulvapron+ or other compatible products should be applied in a minimum total spray volume of 1.5 L/ha. It should only be applied by aircraft with suitable equipment to provide a droplet size of approximately 80-100 microns VMD.
Applications should be made during the cooler parts of the day or at night. Avoid application in calm or very windy conditions. Prefera

Low Volume and High Volume applications by ground rig or aircraft when FASTAC Duo is applied with water carrier.
Add the required quantity of FASTAC Duo to water in the spray tank and mix thoroughly. Maintain agitation during mixing and application.
Ultra Low Volume (ULV) applications by aircraft when FASTAC Duo is applied with oil based bulking agents.
This product can be mixed with D-C-TRON Cotton Spray Oil or other compatible products (See COMPATIBILITY section).
First add the mixing partner to the spray tank and then, with the agitator in motion, add the required quantity of FASTAC Duo direct to the spray tank. Do NOT mix with water and ensure that no water is in the spraying system.

This product is compatible with D-C-TRATE, D-C-TRON Cotton Spray Oil, Synertrol+, Ulvapron+, Bullet+, Copper hydroxide, Dithane+M45, dicamba, Ensign+, Fusilade+, Fusion+, Kelthane+ MF, Kocide+, Lannate L, NUDRIN Insecticide, NUDRIN 225, Parathion 500 EC, Parathion M500, PIX, Predator+ 300, Ridomil+, Wuxal+, Saboteur+, Select+, dimethoate (ROXION), paraquat, diquat, glyphosate, Tigrex+, Jaguar+, simazine, Simagranz+, SPINNAKER, 2,4-D amine and ester, 2,4-DB, MCPA and Coptrel+.
Do NOT mix FASTAC Duo with wettable powders and water disperable granules BEFORE addition to the spray tank. FASTAC Duo can be mixed with Dithane WDG providing the mixture is agitated efficiently and used immediately. Ultra Low Volume (ULV) application by aircraft
This product should be mixed only with specific ULV formulations of other insecticides, eg. NUDRIN 225, Predator 300, and PBO synergists, when mixed according to the directions on the PBO synergist labels.

Restraints Do NOT apply if rain is expected within 6 hours after application. NOTE: This product is ineffective against synthetic pyrethroid-resistant Helicoverpa armigera larvae longer than 5 mm. All Helicoverpa armigera in NSW and Qld should be treated as being resistant to synthetic pyrethroids. Refer to RESISTANCE MANAGEMENT under GENERAL INSTRUCTIONS. This product is ineffective against synthetic pyrethroid-resistant Plutella xylostella.
Resistance Warning For insecticide resistance management FASTAC is a Group 3A insecticide. Some naturally occurring insect biotypes resistant to FASTAC and other Group 3A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if FASTAC or other Group 3A insecticides are used repeatedly. The effectiveness of FASTAC on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, BASF Australia Ltd accepts no liability for any losses that may result from the failure of FASTAC to control resistant insects.
FASTAC may be subject to specific resistance management strategies. For further information, contact your local supplier, BASF Australia Ltd representative or local agricultural department agronomist.
In NSW and Qld, application of this product to Helicoverpa armigera larvae longer than 5 mm may not only be ineffective but it may increase the level of synthetic pyrethroid resistance.
This product should NOT be used to treat infestations that were not controlled by an earlier application of it or another synthetic pyrethroid. Infestations not controlled by this product should be treated with an insecticide from another chemical group. Application of this product with an insecticide from another chemical group such as NUDRIN will assist with the management of synthetic pyrethroid resistant Helicoverpa armigera.
Protection of wildlife, fish, crustaceans and environment Dangerous to fish and aquatic invertebrates such as yabbies. Do NOT contaminate fish ponds, dams, drains, rivers or streams with product or used containers. Drift and run-off from treated areas may be hazardous to fish or crustaceans in adjacent sites.
Protection of livestock Dangerous to bees. Do NOT spray on any plants in flower while bees are foraging. FASTAC Duo is known to have a deterrent effect on foraging bees for a short period of time after spraying. Risk to bees is reduced by spraying in early morning and late evening while bees are not foraging.
