MAXIMUM APPLICATION RATE: A maximum of 1500g a.i. chlorpyrifos / ha can be applied.

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.

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

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

NOTIFICATION: Notification is only required for aerial use only. The person applying the substance in this situation must:

  • Give written notice to anyone likely to be directly affected (such as owners and occupiers of land, property, buildings or houses immediately next to the application area).
  • Ensure the notification is given at least 2 working days before, but no more than 4 weeks before, each application of the product.
  • Ensure the written notice includes:
  1. Where the product will be applied;
  2. The date and approximate duration of each application;
  3. The steps that notified parties should take to avoid exposure;
  4. The name of the organisation(s) applying the product;
  5. Contact details for the person in charge of the application (phone, email or postal address, including a contact number for immediate contact during application).

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.

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: Triple rinse empty container and add rinsate to spray tank. Triple rinsed containers should be taken to an AgRecovery collection site. Do not burn empty containers.

FIRST AID: If swallowed do NOT induce vomiting. For advice, contact the National Poisons Centre on 0800 POISON (0800 764766) or a doctor immediately. If spilt on the skin, remove contaminated clothing and wash affected areas of skin. DO NOT SCRUB THE SKIN. If concentrate is splashed in eyes flush with running water for at least 15 minutes. Take to hospital without delay.


WITHHOLDING PERIODS: Pasture, Fodder crops – 7 days. Grapes, maize, avocados – 14 days. Cereals for harvest – 8 weeks. Kiwifruit – Do not apply after bud cracking (first visible petals). Squash – 10 days.

MIXING: Pour the correct amount of Pychlorex 48EC into the partly filled spray tank. Agitate and add the remainder of the water.

COMPATIBILITY: Pychlorex 48EC is compatible with most commonly used pesticides. It is not compatible with highly alkaline materials such as Bordeaux mixture and lime sulphur.

RESISTANCE MANAGEMENT: Pychlorex 48EC is a GROUP 1 INSECTICIDE from the organophosphate chemical group. Resistance to this insecticide and related organophosphate insecticides could develop in some disease situations from repeated use. To minimise this risk, use strictly in accordance with the label instructions and alternate with insecticides from alternative chemical groups. Follow individual crop resistance management strategies or refer to the NZPPS website:


DIRECTIONS FOR USE: The rates suggested for orchard crops are for high volume spraying to runoff. For concentrate spraying, adjust dilution rate accordingly.

Avocado: Leafroller. Use 50-75ml/100 litres of water as a high volume spray to run off. For aerial application, use 1.7 litres/ha in sufficient water for good coverage. Apply pre-flowering, at complete petal fall, then at 21 day intervals until late April, or after April if leafroller is still present.

Kiwifruit: Greedy scale. Use 50ml per 100 litres of water as a dilute spray or not less than 1 litre per hectare. Make the first application at green tip (at least 10 days after the dormant lime sulphur treatment) and repeat just before blossom. Complete wetting of vine trunks, leader and canes is essential for greedy scale control. The addition of a non-ionic wetting agent is recommended.

Grapes: (except table grapes): Leafroller, Mealy bug, aphids, scale crawlers. Use 50-75ml per 100 litres of water. Use the higher rate for mealy bug control or when insect pressure is high. Apply at bud swell (with intermediate oil), pre-flowering, post-flowering and 14 days later, then every 21 days until harvest.

Pipfruit and Stonefruit: Pre-flowering: Mealy bug, scale crawlers, woolly aphid. Use 80ml per 100 litres of water. Ensure complete coverage. For pipfruit apply at bud movement with a suitable spraying oil. Repeat without oil 10-14 days later at tight cluster. For stonefruit apply at early bud movement with a suitable spraying oil. NB: Do not use Pychlorex 48EC after petal fall.

Winter Squash:Caterpillars, aphids. Apply 500ml/ha in approximately 200 litres of water as a single application soon after emergence, at the first sign of insects or insect damage. As a pre-harvest clean-up, apply 500ml/ha in at least 50 litres/ha of water (aerial), or 500 litres/ha of water (ground), only when flowering has finished and bees are not present in the crop.

Brassicas: Aphids. Apply 300-400ml/ha using 100-200 litres of water per hectare for ground application, or 50-100 litres of water per hectare for aerial application. Nysius: Apply 1.25 litres/ha to seedling brassica crops as soon as damage is apparent.

Springtails: Use 200ml/ha in 50-200 litres of water/ha. Apply 1-2 days before crop emergence or as soon as damage is first noticed.

Ryegrass/Cereals: Argentine stem weevil. Apply 1.25 litres/ha as soon as eggs are present on the lower leaf sheath.

Pasture: Lucerne flea: Use 200ml/ha. Apply in late autumn/early winter at first sign of clover damage. Army caterpillar: Apply 400ml/ha when damage is first seen (usually associated with severe flood damage). Use 100-200 litres of water per hectare for ground application or 50-100 litres of water per hectare for aerial application. Porina caterpillar: Apply 1.25-1.7 litres in 50-200 litres of water per hectare. Use the low rate against small caterpillars, before frosts occur. Closely graze pasture before spraying. Tasmanian Grass Grub: Use 1.25 – 1.5 litres/ha in 100-200 litres of water/ha. Apply to short dry pasture between April and June at first signs of pasture damage. Harrowing of dung patches is recommended prior to spraying, to expose the larvae. Use higher rates when the population is large.

Maize: Army caterpillar, corn earworm: Use 500ml/ha. Apply immediately damage is first seen and repeat if necessary 14-21 days later. Cutworm: Use 600ml/ha in sufficient water for complete coverage of the seedlings and surrounding soil. Spray in the evening at first signs of damage. Lucerne: Aphids: Use 300-450ml/ha. Apply as soon as aphids appear. Use the lower rate on short crops with little leaf and the higher rate on tall crops. Do not spray plants in flower. Sitona weevil: Apply 600- 800ml/ha in 100-200 litres of water/ha to control adults in mid-late May, after flights cease and before egg laying occurs. Use the high rate in dense stands and spray during a warm calm day.
