Active Ingredient: 500g/kg pirimicarb

hemical Group: CARBAMATE

Formulation: Water dispersible granule

Piritek is a fast acting aphicide with contact, translaminar and fumigant activity - especially during warm weather. It is selective to aphids and does not harm many beneficial insects. Importantly, it is effective against aphids that have become resistant to organo-phosphates (OP's) or synthetic pyrethroids (SP's).

DANGER: When handling wear full protective clothing such as gloves, hat, coat and trousers (worn outside rubber boots). Suitable or appropriate respiratory and eye protection should also be worn. WARNING: This substance may be harmful if swallowed, inhaled or absorbed through the skin, and may cause irritation to eyes. Avoid eye contact. May cause internal organ damage from repeated oral exposure at high doses. Avoid inhalation of vapours or mist from spray. May cause sensitisation from prolonged skin contact. Avoid skin contact.
ECOTOXICITY: VERY TOXIC TO AQUATIC ORGANISMS. DO NOT contaminate an aquatic environment with chemical or empty container. DO NOT spray over, or allow drift to drift over, an aquatic environment. Must not be applied onto or into water. DO NOT allow drift outside the target area to occur. Spray must not be applied in an area where bees are foraging. Toxic to the soil environment. Very toxic to terrestrial vertebrates. Very toxic to terrestrial invertebrates.


HANDLING PRECAUTIONS: EQUIPMENT: Apply using calibrated and maintained equipment in accordance with the NZ Standard for the Management of Agrichemicals (NZS8409).

STORAGE: Store in original container tightly closed and in a locked, dry, cool, well ventilated area, away from foodstuffs. Storage must be generally in accordance with the NZ Standard for the Management of Agrichemicals (NZS8409).

SPRAY DRIFT: The person applying the substance must not cause adverse effects beyond the boundary of the treated property, and must also avoid adverse effects from spray drift occurring. Mitigation measures employed must be recorded as part of the application records.

PERSONAL PROTECTIVE (PPE) AND RESPIRATORY PROTECTIVE EQUIPMENT (RPE): Avoid contact with eyes and skin. Avoid inhalation of vapour or spray mist. When mixing or applying, wear chemical resistant overalls, chemical resistant boots and gloves, chemical resistant footwear plus socks, chemical resistant head gear, eye protection and respirator (organic vapour and particulate matter). Clean protective clothing daily after work. Do not eat, drink or smoke while using. Remove protective clothing and wash hands and face thoroughly before meals and after work. Avoid handling, mixing or use of the product or container near heat, flame or other source of ignition.

Do not use near air vents or ducts. Apply with well maintained and calibrated spray equipment.

THIS PRODUCT IS VERY TOXIC TO BEES. Do not apply this product to any plant or tree likely to be visited by bees:

  • At the time of application; or
  • Immediately after application until spray has dried; or
  • In areas where bees are foraging.

RESTRICTED ENTRY INTERVAL (REI): The REI is 24 hours. The person in charge is responsible for making sure no person enters the application area before the end of the REI. A person may only enter the indoor treated area if PPE and RPE is worn as if they were applying the substance, and they are entering to carry out tasks associated with the ventilation of the building or building structure.

SPILLAGE: Wear appropriate protective clothing and prevent material from entering waterways. Absorb spills with inert material and place in waste containers. Wash area with water and absorb with further inert material. Dispose of waste safely, according to local Council regulations.

DISPOSAL: Crush and bury in a suitable landfill. Do not burn empty packaging.

Piritek is a GROUP 1 INSECTICIDE and is a member of the carbamate chemical group. Resistance to this insecticide could develop from excessive use. To minimise this risk use strictly in accordance with the label instructions and resistance management strategies that exist for any pest listed on the label. Piritek should be used in a programme that incorporates insecticides with different modes of action to that of GROUP 1 INSECTICIDES. Refer to the NZCPR website: ( for more detailed information.

GENERAL INFORMATION: PIRITEK is a fast-acting contact insecticide which is partially systemic and has strong fumigant action within the crop. It is effective on most aphid species in a wide range of agricultural and horticultural crops and active on strains of aphids resistant to organophosphate insecticides. Aphids controlled by PIRITEK at recommended rates include: Black Bean Aphid, Blue Green Lucerne Aphid, Cabbage Aphid, Cereal Aphid, Grain Aphid, Rose-Grain Aphid, Green Peach Aphid, Pea Aphid, Potato Aphid and Rose Aphid.

It is an offence to use this product on animals.

DIRECTIONS FOR USE TIME OF APPLICATION: Apply PIRITEK when aphids appear and repeat applications as required for crop hygiene and protection. It is recommended that vegetation growing on the crop perimeter be inspected regularly and if necessary treated to reduce the risk of crop reinfestation.

APPLICATION: A non-ionic low foam wetting agent at label rates is recommended for difficult-to-wet crops such as brassicas and potatoes. Rates suggested in horticulture are for high-volume spraying to run-off. For concentrate spraying, adjust dilution rate accordingly.

Crop Pest Rate Critical comments
Apples Woolly Apple Aphid 50 g/100 litres of water (or no less than 1 kg/ha) Add a non-ionic low foam wetting agent at label rates for summer applications Where a high over-wintering pest population exists, apply at bud- movement plus a suitable spraying oil. To control Woolly Apple Aphid infesting shoot growth during summer pest build-up, apply as required during the growing season. Timing of application should be in accordance with infestation thresholds such as outlined in the Pipfruit NZ guidelines. Concentrate spraying is NOT recommended.
Beans, Broadbeans, Oil Seed, Peas, Rape Aphids 250 g/ha Apply in a minimum of 200 litres of water from the ground or 100 litres from the air.
Cereals, Lucerne, Kale, Swedes, Turnips Aphids 200 to 250 g/ha Use the lower rate only on short or sparse crops. Apply in a minimum of 200 litres of water from the ground or 100 litres from the air.
Cucurbits Aphids 250 g/ha Apply as a preventative spray over the flowering period with a second application 10 to 14 days later. A third application may be applied if required later in the season. Apply in 200 to 700 litres of water from the ground or 100 litres from the air.
Lettuce, Tomatoes, Vegetable Brassicas Aphids 250 g/ha Apply in 400 to 700 litres of water, depending on stage of crop development.
Potatoes Aphids 500 g/ha Apply in 200 to 400 litres of water at a pressure of not less than 500 kPa.
Stonefruit Aphids 25 g per 100 litres of water Apply in a minimum of 2000 litres of water per hectare.
FLOWERING CROPS: Broadbeans, Clovers, Forage Brassicas Lucerne, Peas, Oil seed rape Aphids 250 g/ha Avoid direct contact with bees by applying in the evening when bees are NOT foraging.

MIXING: Pour the measured quantity of PIRITEK into a partly filled tank and agitate the spray mixture while adding the remaining water. The spray mixture should be continually agitated before and during spraying and after a stoppage.

EQUIPMENT: PIRITEK is non-corrosive and almost non-abrasive and can be applied through standard ground and aerial spraying equipment. Flush equipment with clean water after use. Surplus spray solution and washings from equipment should NOT be disposed of on cropping land or in streams.

IT IS AN OFFENCE for users of this product to cause residues exceeding the relevant MRL in the New Zealand (Maximum Residue Limits of Agricultural Compounds) Food Standards.
