Pyrethrum 5EC 250ml

Pyrethrum 5EC Natural Organic Insecticide – 250 ml

Pyrethrum 5EC is a highly effective, plant-based insecticide derived from dried Chrysanthemum flowers. Formulated as a professional-grade, emulsifiable concentrate, it delivers rapid knockdown of a broad spectrum of pests while breaking down quickly—leaving virtually no residue and allowing safe harvest within 24 hours.

Key Benefits

• Fast-acting contact insecticide that disrupts the nervous systems of pests

• Controls aphids, whitefly, greenfly, blackfly, thrips, caterpillars, fungus gnats, springtails, red spider mite, tobacco beetles, beetles, moths, and more

• Suitable for both organic and conventional growing methods

• Rapid environmental breakdown ensures minimal residue and a 24-hour safe harvest interval

• Can be applied in indoor, greenhouse, and outdoor systems across soil, coco, and hydro setups

• Low risk of resistance development thanks to the natural mix of pyrethrins and synergist—effective even with repeated use

How It Works

Contains 5% w/v pyrethrins, derived naturally from chrysanthemum flowers, combined with piperonyl butoxide to enhance its potency by inhibiting pests' detoxification processes. It acts only upon direct contact with insects, making it safe for plants when used correctly. 

How to Use

• Mixing Rate: 4–20 ml per 5 litres of water (0.08–0.4% solution), equivalent to 0.02% (20 ml in 5 L) for general use

• Apply using a fine spray, ensuring thorough coverage of both upper and lower leaf surfaces

• Best applied during early morning or evening to minimize heat stress and UV breakdown

• Safe for use on edible crops, including vegetables and fruit; harvest may resume just 24 hours after application

Safety & Handling

• Use protective gloves, clothing, and eye protection during handling

• Avoid drift to non-target areas; highly toxic to aquatic life

• Not recommended for ponds, aquariums, or environments with beneficial insects

• Use in well-ventilated areas, and never inhale the spray mist

• Store securely, away from children and pets, in accordance with pesticide regulations 

Environmental Notes

Pyrethrum breaks down rapidly under light and air exposure, reducing residue risk. However, it remains very toxic to aquatic organisms, so care must be taken to avoid contamination of water sources.
