DO NOT GRAZE OR CUT TREATED COTTON CROPS FOR STOCK FOOD
Citrus: DO NOT HARVEST FOR 7 WEEKS AFTER APPLICATION
Tomatoes: DO NOT HARVEST FOR 6 WEEKS AFTER APPLICATION

EXPORT TRADE ADVICE – TREATED CROPS
Citrus destined for export markets may require a longer withholding than specified above. To account for countries where a lower MRL or no MRL has been set a withholding period of 22 weeks should be observed. DO NOT use later than the growth stage GS72-73, ie green fruit surrounded by sepal crown.
Treated tomatoes grown in a protected cropping situation that are destined for export markets may require a longer withholding period than specified above, to be accepted in some export markets. Before using this product, you are advised to contact Syngenta and/or your industry body about any potential trade issues and their management.

GENERAL INSTRUCTIONS
Mixing
Add the required amount of ACTARA to clean water in half-filled spray tank with the agitator or by-pass in operation. Maintain agitation while filling tank with remainder of water. Agitate whilst spraying.

Tomatoes via Drip/Trickle Irrigation
ACTARA should be applied through direct injection into drip/trickle irrigation systems. Injection equipment must be accurately calibrated to achieve the required application rates prior to treatment (see Application).
Calculate the amount of Actara required based on the number of plants to be treated. The amount of Actara to be used must not exceed the total dose required. Prepare the injection solution using a minimum dilution for injection of 8 g of product in 1 L of water. The volume of the injection solution should not exceed what can be injected in ¼ of the total irrigation volume. DO NOT prepare more injection solution than required to dose the total number of plants to be treated.

Application
To be effective ACTARA requires thorough spray coverage. Ensure that equipment is properly calibrated to give an even distribution at the correct volume.
Ground Application: Apply as a spray in a minimum of 100 L water/ha.
Aerial Application: Apply in a minimum of 30 L water/ha.

Tomatoes
Drip/Trickle Irrigation
Apply a single application from 2 days after transplanting or once seedlings have started to recover from transplanting stress.
ACTARA should be applied through direct injection into drip/trickle irrigation systems. Injection equipment must be accurately calibrated to achieve the required application rates prior to treatment. ACTARA should be incorporated into the normal irrigation schedule at the recommended timing within the irrigation cycle. Even distribution is essential. Irrigation systems should be monitored periodically to ensure all delivery points are in working order and there are no clogs or blockages.

The ACTARA injection solution (see Mixing) should be injected into irrigation systems during the third quarter of the irrigation cycle, after the soil has been partially wetted up. The duration of injection should be long enough to distribute ACTARA uniformly, this will vary greatly depending on irrigation system setup and design, area of crop treated, emitter type, irrigation flow rates etc (refer to the manufacturer specifications for the irrigation system). To achieve this inject ACTARA over a period of at least twice the duration that it takes irrigation water to travel between the point of injection and the last emitter. This duration should be determined by observing the time it takes for the last emitter to be fully operational after commencement of the irrigation cycle.

The final quarter of the irrigation cycle is used to flush product from system. DO NOT over irrigate. Soil or growing media moisture levels should be at or slightly below field capacity at the end of the application and irrigation cycle.

Planting Hole Drench Application
ACTARA should be applied with water in a minimum total volume of 50 mL per seedling directly at the base of transplanted seedlings or into the planting hole immediately before transplanting. Actual total volume will vary depending on equipment used, pre-existing soil moisture levels and soil type but should be sufficient to ensure uniform application and distribution.
With applications made after transplanting ACTARA should be incorporated to seedling root depth using sufficient irrigation within 24 hours.

Citrus
Dilute Spraying
Use a sprayer designed to apply high volumes of water up to the point of runoff 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 runoff. Avoid excessive runoff. 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 water. Spray to the point of runoff. The required dilute spray volume will change and the sprayer set up and operation may also need to be changed, as the crop grows. DO NOT exceed a water volume of 5000 L/ha.

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 runoff) 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) 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:

Example only
1. Dilute spray volume as determined above: For example 4000 L/ha
2. Your chosen concentrate spray volume: For example 2000 L/ha
3. The concentration factor in this example is: 2 X (ie. 4000 L / 2000 L = 2)
4. If the dilute label rate is 20 g/100 L, then the concentrate rate becomes 2 x 20, that is 40 g/100 L of concentrate spray.

The chosen spray volume, amount of product per 100 L water, and the sprayer set up and operation may need to be changed as the crop grows.
DO NOT use a concentrate rate that exceeds a total application rate of 1.5 kg product/ha.
For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

Compatibility
As formulations of other manufacturer’s products are beyond the control of Syngenta Crop Protection, and water quality varies with location, all mixtures should be tested prior to mixing commercial quantities.

Insecticide Resistance Warning
For insecticide resistance management ACTARA Insecticide is a Group 4A insecticide. Some naturally occurring insect biotypes resistant to ACTARA and other Group 4A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if ACTARA and other Group 4A insecticides are used repeatedly. The effectiveness of ACTARA on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Syngenta Crop Protection accepts no liability for any losses that may result from failure of ACTARA to control resistant insects. ACTARA may be subject to specific resistance management strategies. For further information contact your supplier, Syngenta Crop Protection representative or local agricultural department agronomist.

Aphid Resistance Management
Aphicides from the same chemical group should not be applied consecutively. DO NOT apply more than two applications of a product from the same chemical group in one season. For managing aphid resistance, organophosphates and carbamates should be regarded as the same chemical group. The first aphicide application of the season must be from a different chemical group than the last aphicide application of the previous season. If a neonicotinod seed treatment such as Cruiser or Gaucho is used, the first aphid spray of the season must not be ACTARA or any other group 4A insecticide. Use ACTARA in accordance with the industry Insecticide Resistance Management Strategy.
