WHP: 3 days grazing
Critical Comments: 
Application
High rate to be used when there is a high aphid population density or with dense crop growth. Complete coverage and penetration of the crop is essential.
Timing
Queensland only:
On seedling lucerne, treatment is necessary when 1 or 2 aphids are present per plant. Established lucerne and medics (spring and summer) - spray when there are 20 to 40 aphids per stem. Spotted Alfalfa Aphid (NSW, Tas, SA, WA only): Apply when aphids begin to build up on stems and repeat as necessary.
Spotted Alfalfa Aphid and Pea Aphid (Vic only): Seedling lucerne and medics - treat when 1 to 2 aphids per plant are present. Established lucerne and medics (spring and summer) - spray when there are 20 to 40 aphids per stem.
Tasmania only:
A cold weather adapted species which may be found at most times of the year.
Spraying should be carried out when aphids begin to increase and be repeated as necessary.
For the control of both the above lucerne and medic pasture pests PIRIMOR WG at the recommended rate should be applied in 200 to 300 L of water/ha. Complete coverage and penetration of the crop is essential.
Blue Green Aphid
This aphid is cooler weather tolerant and will be found at all times of the year.
Spraying should be carried out as aphids are observed.
In some areas Spotted Alfalfa Aphid has developed tolerance to pirimicarb and in those areas PIRIMOR will not give satisfactory control. However, apparent tolerance should not be confused with poor application. Consult your local Syngenta or Department of Agriculture representative for local information.

GENERAL INSTRUCTIONS
Mixing
Fill tank 50 to 75% full then start agitation. Slowly pour granules into tank and maintain agitation throughout spraying. DO NOT pre-mix PIRIMOR granules.

Application
If this product is applied when the temperature is less than 15C it is essential to have thorough spray coverage for quick and total aphid control.

Fruit Crops - Tree and Vine Crops
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 of 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.

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:
- Dilute spray volume as determined above: For example 1500 L/ha.
- Your chosen concentrate spray volume: For example 500 L/ha.
- The concentration factor in this example is: 3 X (ie 1500 L  500 L = 3)
- If the dilute label rate is 10 mL / 100 L, then the concentrate rate becomes 3 x 10, that is 30 mL / 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 changed as the crop grows. For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and following industry Best Practices.

Compatibility
PIRIMOR WG may be mixed in the spray vat with any one of the following products: Agral and Omite*. A mixture of PIRIMOR WG with more than one of these products or with any other product may be ineffective or may cause serious damage. The use of such a mixture is not recommended and would therefore be entirely at the user’s risk.

GROUP 1A INSECTICIDE

Insecticide Resistance Warning
For insecticide resistance management PIRIMOR WG Aphicide is a Group 1A insecticide. Some naturally occurring insect biotypes resistant to PIRIMOR WG and other Group 1A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if PIRIMOR WG or other Group 1A insecticides are used repeatedly. The effectiveness of PIRIMOR WG on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Syngenta Crop Protection Pty Limited accepts no liability for any losses that may result from the failure of PIRIMOR WG to control insects. PIRIMOR WG may be subject to specific resistance management strategies. For further information contact your local supplier, Syngenta Crop Protection representative or local agricultural department agronomist.

Resistance Management for Green Peach Aphid Control
Some Green Peach Aphids are resistant to all commonly used insecticides including PIRIMOR WG. If resistance is known or suspected, DO NOT use PIRIMOR WG and seek advice on resistance management. If there is no PIRIMOR WG resistance, use a maximum of 2 non-consecutive aphid sprays per season. If PIRIMOR WG was used as the last aphid spray for the season, DO NOT use it as the first aphid spray next season.
