Pyrethrum 5EC

Fast natural knockdown for sap-sucking pests

Pyrethrum 5EC is a natural pyrethrin-based contact insecticide approved for use outdoors, in greenhouses and on pot plants throughout the season. It controls aphids, blackfly, greenfly, caterpillars and whitefly on flowers, fruit and vegetables, drawing its active punch from botanical pyrethrins rather than synthetic chemistry - a fast-acting option for growers keeping their spray programme organic-friendly. MAPP No. 18532. For professional use only.

Key Benefits

• Broad-spectrum control of aphids, blackfly, greenfly, caterpillars and whitefly
• Natural pyrethrin formulation from botanical sources, not synthetic actives
• Fast knockdown on contact, hitting active infestations before they spread through the canopy
• Suitable for flowers, fruit and vegetables across outdoor, greenhouse and pot-plant use
• Season-long use as populations flare and reappear

Aphids and whitefly multiplying faster than you can spray?

Sap-sucking pests like aphids and whitefly breed explosively once established, weakening plants and spreading through the canopy, while caterpillars can strip leaves in days. Applied as a thorough contact spray, Pyrethrum 5EC knocks populations back before an infestation runs out of control.
