Division Question (b): For the different uses specified in the applications for renewal, are alternative authorised biocidal products or non-chemical means of control and prevention methods available?
United Kingdom
Tables 2 and 3 provide an overview of the alternatives considered in the opinion in order to address this question.
Table 2
Overview of the alternative authorised biocidal products to the specified uses of anticoagulant rodenticides
| Use number as described in Table 1 | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Active substance in the alternative biocidal products | Application type | #1 | #2 | #3 | #4 | #5 | #6 | #7 | #8 | #9 | #10 |
| Alpha chloralose | Bait | yes | yes | Only mice | |||||||
| Aluminium phosphide releasing phosphine | Fumigant | Only for R. norvegicus | Only for R. norvegicus | ||||||||
| Carbon dioxide | Cannister for trapping device | Only mice | |||||||||
The alternative authorised biocidal products do not cover all the uses specified for anticoagulant rodenticides (see Table 2). For some uses (uses number #2, #3, #5, #6 and #10), no alternative authorised biocidal products are available. For use #7, there are alternative authorised biocidal products only for mice, and for uses #8 and #9 there are alternative authorised biocidal products only for rats (R. norvegicus).
