TARGETED PEST:  Two-striped slug, Veronicella cubensis

Copper hydroxide is usually used as a fungicide but is also formulated as a root growth regulator that prevents root-bound containers. The College of Tropical Agriculture at the University of Hawaii discovered that the copper hydroxide coating is very repellent to the two-striped slug, Veronicella cubensis. Plastic pots, grow bags and weed mats coated with a special formulation of copper hydroxide significantly repelled slugs. (See Spinout, Griffin Corporation, http://www.lerio.com)

For example, in one test, pots were placed in a contained area of 15 square feet with 500 slugs. Copper hydroxide-coated pots harbored an average of zero slugs per pot while uncoated pots harbored an average of 24 slugs per pot.

Presently, copper hydroxide-coated products are not registered for use as a molluscicide but registered only as a root growth regulator.
