The active ingredients in Slasher are made from natural plant oils – a combination of pelargonic acid (nonanoic acid) and orange oil terpenes (D-limonene). Pelargonic acid occurs naturally in plants, including geraniums. Orange oil is an essential oil extracted from citrus peel. Together they act on the foliage, causing it to quickly dehydrate and collapse. Results are seen as browning and wilting, usually within 1 hour of application.

Slasher is a non-selective weedkiller and will control many weed species on contact.
Slasher is non-residual in soil and biodegrades within a few days.
