Hybrid bait formulation

Derrex® slug pellets are manufactured with the help of a new bait technology. The high temperature of the pressing process ensures an optimal agglutination of the starch and protein components contained in the bait. This markedly improves the resistance to rain in comparison with conventional dry baits.


An innovative bait formulation makes Derrex® slug pellets particularly resistant to rain. This means that the pellets will also stay in shape and retain their attractiveness for snails in langer rainfall.

Organic farming

Iron (III) phosphate, the active ingredient of Derrex® slug pellets, is approved for organic farming operations as per EC regulation.

Derrex® is registered with the Research Institute of Organic Agriculture (FiBL).

Public greens

Derrex® is grouped with plant protection prod­ucts that are suitable for areas intended for the general public in the list as per section 17 of the Federal Office of Consumer Protection (BVL) in Germany.


Application in agriculture

Derrex® can either be applied using fertilizer spreaders or special snail pellet spreaders. Please have a look at the homepage of the spreader manufacturer for details of the equip­ment settings and scattering range.

Application date

The treatment should be started as soon as possible directly after the sowing and/or planting. The best time for the application are the early hours of the evening when the snails leave their hiding places.

The application rate of 7 kg/ha must not be re­duced under any circumstances in areas under high infestation pressure and at the edge of the field. In case of a lower infestation rate, the quantity in the field can be reduced to 5 kg/ha.
