Highlights

The most common methods of pest slug control involve the use of chemical bait pellets containing metaldehyde or carbamates (Henderson & Triebskorn 2002)
On subsequent days of observation, significant differences were found for the compared objects in the amount of damage done to the plants by A. vulgaris (F3d = 7.5, d.f. = 5; 28, p < 0.001; F5d = 10.3, d.f. = 5; 28, p < 0.001; F7d = 17.8, d.f. = 5; 28, p < 0.001; F9d = 15.4, d.f. = 5; 28, p < 0.001; F11d = 20.5, d.f. = 5; 28, p < 0.001; F13d = 15.9, d.f. = 5; 28, p < 0.001 and F15d = 28.7, d.f. = 5; 28, p < 0.001)
The study of the effectiveness of the molluscicide containing iron phosphate compared with those containing methiocarb and metaldehyde showed that the substances had lethal effects on slugs, causing a reduction in their grazing, and in the damage done to plants

Summary

Introduction

The most common methods of pest slug control involve the use of chemical bait pellets containing metaldehyde or carbamates (methiocarb, thiodicarb) (Henderson & Triebskorn 2002). The use of molluscicides containing these active substances causes numerous problems relating to their application and their adverse impact on the environment. Both substances are toxic to vertebrates (Fletcher et al 1994), and methiocarb is toxic to useful invertebrates such as ground beetles (Purves & Bannon 1992). Laboratory and field experiments have demonstrated a high effectiveness of iron phosphate in protection of various plant species, there are differences in the level of protection achieved against different slug species (Koch et al 2000, Iglesias & Speiser 2001, Iglesias et al 2001a, Speiser & Kistler 2002, Rae et al 2009). The recommended dose of the iron phosphate molluscicide 1% (Ferramol) is high (2.5 to 5 g/m2), which makes
