In order to compare the efficacy of different formulations of Bromodiolone-based
rodenticides against mixed populations of common vole (Microtus arvalis Pall) and striped
field mouse (Apodemus agrarius) in alfalfa, the testing was conducted using the standard
EPPO method at the locations of Belegiš and Putinci, in summer of 2010. The experimental
design consisted of a completely randomized block with four replicates and with the main
plot area of 400 m2. The abundance and distribution of small rodents populations at the
experimental plots were determined on the basis of appearance and spatial distribution of
active holes. The efficacy of different rodenticide formulations was evaluated according to the number of active holes 7, 14, and 28 days after treatment (DAT), using the Henderson-
Tilton’s formula. The testing was done with the commercially available rodenticide formulations:
AB (grain-based baits), RB (ready-to-use baits – pouches) and PT (pellets), containing
0.005% of active ingredient Bromodiolone.
The monofactoral analysing of variance did not result in any statistically significant difference
in efficacy of rodenticide formulations 7 DAT at the Belegiš locality and 7 and 14
DAT at the Putinci locality. But, the statistically significant difference in efficacy of rodenticide
formulations was observed at Belegiš locality on the 14th day of the experiment. Also,
at the end of experiment, the efficacy of rodenticide formulations significantly varied at
both locations. Nominally, the lowest efficacy of 72.5% was exhibited by AB formulation,
while the average efficacy of RB and PT formulations against mixed populations of common
vole and striped field mouse in alfalfa was 88.3% and 77.7%, respectively. It is concluded
that the use of RB formulation of Bromodiolone-based rodenticides can improve the
control of rodent pests in alfalfa. Radi poređenja efikasnosti različitih formulacija rodenticida na bazi bromadiolona u
suzbijanju mešanih populacija poljske voluharice i poljskog miša u usevu lucerke, prema
standardnoj metodi EPPO izvedeni su eksperimenti u proleće 2010. godine na lokalitetima
Belegiš i Putinci. Eksperiment je postavljen po potpuno slučajnom blok sistemu, sa četiri
ponavljanja i veličinom osnovne parcele od 400 m2. Na osnovu izgleda i prostornog rasporeda
aktivnih rupa utvrđena je zastupljenost vrsta sitnih glodara i njihova brojnost na eksperimentalnim
parcelama. Efikasnost formulacija rodenticida je ocenjivana prema formuli
Henderson & Tilton, na osnovu broja aktivnih rupa, sedam, 14 i 28 dana posle tretmana.
Ispitivane su komercijalno dostupne formulacije rodenticida: AB (zrnasti mamak), RB (gotov
mamak za upotrebu – kesice) i PT (pelete), sa sadržajem 0,005% aktivne materije bromadiolona.
Jednofaktorijalnom analizom varijanse nije utvrđena statistički značajna razlika između
efikasnosti formulacija rodenticida posle sedam dana na lokalitetu Belegiš i posle sedam i
14 dana na lokalitetu Putinci. Na lokalitetu Belegiš, 14-og dana od početka eksperimenta
postojala je statistički značajna razlika između efikasnosti formulacija rodenticida. Takođe, i
na kraju eksperimenta, efikasnost formulacija rodenticida se statistički značajno razlikovala
na oba lokaliteta. AB formulacija rodenticida imala je nominalno najnižu prosečnu efikasnost
od 72,5%, dok je prosečna efikasnost RB i PT formulacije bila viša, 88,3%, odnosno
77,7% u suzbijanju mešanih populacija poljske voluharice i poljskog miša u lucerki. Upotrebom
RB formulacije rodenticida na bazi bromadiolona moguće je unaprediti program zaštite
lucerke od štetnih glodara.
