How Our Pyrethrum Insecticides Work
Our Pyrethrum-based solutions (also known as pyrethrin insecticide) are a natural, fast-acting and effective way to control pests. Derived from the dried flowers of Tanacetum cinerariifolium (pyrethrum daisies), these formulas work by disrupting the nerve function of insects, causing rapid paralysis and death within minutes of contact. They contain six active compounds—pyrethrins and related esters—which make it difficult for pests to develop resistance.
How should I mix and apply Kendon Pyrethrum?
For best results, shake the container well before use. Mix the recommended amount of this solvent-free product with water (as per label instructions). Apply the mixed pyrethrin solution as a fine mist spray, ensuring thorough coverage of the affected plants. In commercial applications, use calibrated ground spraying equipment to apply 500-1500 litres of water per hectare, depending on the size of the crop, but avoid excess run-off. For knapsack applications, follow the label instructions for dilution rates. Apply at dusk or in overcast conditions to maximise effectiveness and slow UV breakdown.

Is pyrethrin safe for use on edible crops and in home gardens?
Yes, when used as directed, these solutions are safe for edible crops and home gardens. Our formulations break down quickly when exposed to sunlight, leaving minimal residue. You can harvest treated vegetables just one day after application, making them ideal for growers and gardeners who value both safety and effectiveness.
What pests can I control with Kendon’s pyrethrin-based insecticides?
Kendon’s pyrethrin formulas effectively control a broad spectrum of common garden pests, including aphids, ants, caterpillars, leaf hoppers, glasshouse whitefly, thrips, and outdoors only for houseflies and cockroaches. These products are suitable for use on vegetables, ornamental flowers and roses, fruit trees, indoor plants and ferns.
When and how often should I apply these solutions during the growing season?
Apply our solutions at 5–7 day intervals during crop growth, or more frequently during periods of heavy pest pressure. Spraying at the first sign of larvae or insect infestation helps minimise crop damage and keeps pest populations under control. Apply at dusk to slow breakdown and extend period of insect exposure.
Can I mix these formulas with other garden products?
Yes, Kendon’s pyrethrum formulations are compatible with Triforine Rose Fungicide and Kanolacide Spray Adjuvant (canola oil). Mixing with an adjuvant can enhance spray coverage and slow down UV degradation, improving pest control results. Always follow label instructions for compatibility and safe use.
What is the withholding period after application on vegetables?
The withholding period for Kendon’s pyrethrin formulations is just one day. This means you can safely harvest and consume treated vegetables one day after spraying, provided you follow all label instructions.
Why choose a natural insecticide over synthetic options?
Natural insecticides like pyrethrum offer quick knockdown of pests, minimal environmental impact, and low risk of resistance development. Pyrethrum breaks down rapidly in sunlight, leaving little residue, and is safe for use in organic gardening when used according to directions. Its broad-spectrum action makes it a versatile solution for both home gardeners and commercial growers.
What safety precautions and storage guidelines should I follow?
Always store pyrethrum insecticides in the original, closed container in a cool, dry place out of direct sunlight and out of reach of children. Do not spray directly on humans, pets, food, or food preparation areas and utensils. Avoid contaminating drains, water sources, ponds and fish tanks. Dispose of empty containers responsibly, and wash application equipment thoroughly after use. In case of accidental poisoning, contact a doctor or Poisons Information Centre immediately.
