Chlorpyrifos belongs to IRAC Group 1B and inhibits acetylcholinesterase in susceptible insects. Cypermethrin belongs to IRAC Group 3A and acts on insect nerve sodium channels. The two target sites are combined in one premix. Where another treatment is necessary, follow the label and rotate to an effective insecticide from a different IRAC group rather than repeatedly relying on Group 1B + 3A.

PHI = Pre-Harvest Interval. The current physical pack label controls. Do not extend this use table to unlisted crops, pests or soil treatments.

• Scout the crop and confirm a registered target pest before treatment.
• Measure the crop-specific quantity and apply with the label water volume using calibrated equipment.
• Pre-mix the measured EC in a small quantity of clean water, add it to the tank, then top up while agitating.
• Apply during calm conditions and obtain uniform coverage while preventing drift.
• No tank-mix recommendation is made here. Recommendations below are standalone alternatives.

• Wear the protective clothing, chemical-resistant gloves, eye protection and respiratory protection required by the current label.
• Avoid skin, eye and mouth contact and avoid breathing spray mist or vapour.
• Do not eat, drink or smoke while handling or applying the product; wash thoroughly afterwards.
• Protect bees by avoiding spray during active foraging and flowering exposure as directed on the label.
• The formulation is hazardous to aquatic organisms and birds; prevent drift, runoff and rinsate from reaching water bodies, aquaculture areas and bird habitat.
• Store locked in the original container away from children, livestock, food and feed. Do not reuse empty containers.

Always read and follow the current official product label and leaflet. Crop, pest, dose, water volume, timing, PPE, environmental precautions and PHI must match the label. Related and upsell products are alternatives, not tank-mix instructions.
