Details & Formulations

Pyrethrum 5EC is a natural insecticide containing 5% natural pyrethrum and will therefore kill most insect predators used in integrated pest management programmes (IPM). Natural pyrethrum has not been notified as an insecticide with a high risk resistance, and it is synergised in this product with piperonyl butoxide (prepared from a a natural oil). Therefore insects are extremely unlikely to develop resistance to Pyrethrum 5EC.

Pyrethrum 5EC can be used on ornamentals, fruits and vegetables such as strawberries, raspberries, lettuce, cabbages, tomatoes, cucumbers, peppers etc. It is for use against a wide range of Irish pest insects including aphids, caterpillars, moths, flea beetle, red spider mite (or "velvet mite" or "blood suckers"), thrips, whitefly, blackfly, greenfly etc.
