General Instructions


Dominex Duo Insecticide 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 larvae. Best results will be obtained by spraying at egg hatch. Thorough coverage is essential to ensure adequate control. Apply during the cooler parts of the day or night. The product can be applied mixed either with water or oil based bulking agents such as DC-TRON Spraying Oil or compatible ULV products.




Low Volume and High Volume applications by ground rig or aircraft when Dominex Duo is applied with water carrier.

Add the required quantity of Dominex Duo Insecticide to water in the spray tank and mix thoroughly. Maintain agitation during mixing and application.

Ultra low volume (ULV) applications by aircraft when Dominex Duo is applied with oil based bulking agents.

This product can be mixed with DC-Tron Spraying 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 Dominex Duo Insecticide to the spray tank.


DO NOT mix with water and ensure that no water is in the spraying system.




APPLICATION Grapevines, pome and stone fruit


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:

(a) 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 runoff)

and matched to the crop being sprayed.

(b) Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.

(c) Determine an appropriate dilute spray volume (See Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate.

(d) The mixing rate for concentrate spraying can then be calculated in the following way:


Example only:

1. Dilute spray volume as determined above: For example 1000 L/ha.

2. Your chosen concentrate spray volume: For example 500L/ha.

3. The concentration factor in this example is: 2 X (ie. 1000L ÷ 500L = 2).

4. If the dilute label rate is 50 mL/100L, then the concentrate rate becomes 2 x 50, that is 100 mL / 100L of concentrate spray.

(e) The chosen spray volume, amount of product per 100L of water, and the sprayer set up and operation may need to be changed as the crop grows.

(f) 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.


APPLICATION – Crops other than grapevines, pome and stone fruit


Low Volume and High Volume by ground rig or aircraft when Dominex Duo is applied with water carrier. Dominex Duo Insecticide 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, 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 than30cm. The application should be made as a fine spray, preferably using hollow cone nozzles and a droplet size of 150-200 microns.


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 applications to cereals, linola, canola, rice and to other dense crops, apply a total spray volume of 30 to 35L/ha. If possible, spray in a cross wind. 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

Dominex Duo, mixed with DC-Tron spraying oil or compatible products, should be applied in a minimum total spray volume of 1.5L/ha. The minimum

application volume in cotton should be 3L/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. Preferably apply in light to moderate cross wind.
