Pyrethrum is the fastest-acting, most effective, and strongest contact insecticide allowed under National Organic Standards, targeting the widest range of pests, including, but not limited to, chewing and sucking pests like aphids (blackfly and greenfly), caterpillars, whitefly and red spider mite.

Cost-Efficient & Easy To Use As an emulsifiable concentrate (EC), you mix only a maximum of 4ml to 1 litre of water, shake and use. 50ml makes 12.5 litres of spray.

Made by Plants for Plants Pyrethrum (Tanacetum cineraiifolium) is a perennial plant in the family of Asteraceae, which produces the pyrethrins that possess insecticidal properties, as a defence mechanism to ward off pests. 

Rapid Knockdown Action Pyrethrum excites the nervous system of insects that touch or eat it almost immediately. Even before it kills, it knocks down and paralyses insects almost immediately. Pyrethrum also causes the erratic activity of many insects so that they are ‘flushed’ out of their hiding places, increasing their exposure to the insecticide.

Broad Spectrum Because Pyrethrum consists of a group of six related compounds, it has a wider spectrum of activity against insect species than many single insecticides. It can be used against any insect found in the house or garden, and will non-selectively kill any insect you spray it on, including cockroaches, mosquitoes, ants, flies, fleas, wasps, moths, crickets, and other pests.

Low Mammalian Toxicity Crops may be sprayed at 7 day intervals and harvested 24 hours after the last application. Studies and the experience of use over a century demonstrate that pyrethrins are the safest effective organic insecticide. The pyrethrins are extensively metabolised by mammals and quickly excreted from the body. Tested on human volunteers.

Lack of Insect Immunity Pyrethrum is a mixture of six active ingredients. The structure of the molecule is so complex that insect resistance to Pyrethrum is not a practical problem. Any 'survivors' are unlikely to become super-bugs.

Environmentally friendly Easily degraded by oxygen, sunlight, temperature, and changes in pH, into non-toxic products which are immobile in soil, pyrethrum compounds are environmentally friendly and compatible with organic farming.

Proven Insect Repellent As part of the defense mechanism of pyrethrum flowers, pyrethins repel herbivorous insects and recruit carnivorous insects by producing aphid alarm pheromones. Even small amounts of Pyrethrum can jam the 'black box' of the insect’s food searching mechanism. Because of this effect, low level Pyrethrum applications have been shown to reduce the risk of malaria carried by indoor mosquitoes.

Aquatic Toxicity Pyrethrum is highly toxic to fish and other aquatic organisms, so care needs to be exercised when spraying pyrethrum to avoid wind drift near waterways, ponds and water gardens.

Plant Sensitivity Some species of plant may be sensitive to Pyrethrum 5 EC and show signs of yellowing, particularly after a second application. Always test spray before spraying larger batches. Certain types of bedding plants may suffer some damage to any flowers present at the time of spraying. Subsequent new growth is unaffected.
