Biological efficacy of chemical and natural rodenticides in controlling rodents in alfalfa
and wheat crops was investigated. The experiment was set up using a randomized block
design with four replicates and 400 m2 plots in compliace with a standard OEPP/EPPO method.
Examination was based on the average number of active holes and rodenticide efficacy
was measured three, seven, 14 and 28 days after treatment. Rodent numbers were computed
from the number of active holes, and rodenticide efficacy using Abbott’s formula.
The appearance and arrangement of active holes indicated the presence of common vole
(Microtus arvalis Pall) and striped field mouse (Apodemus agrarius) in the plots. The products
tested demonstrated satisfactory efficacy in controlling rodents in alfalfa and wheat
crops. Products based on vitamin D3 achieved 87-90% efficacy in both crops. The efficacy
of a bromadiolone-based product ranged from 84% to 90%, while a cellulose product displayed
the highest variation in efficacy, ranging from 86% to 98%. Ispitivana je biološka efikasnost rodenticida prirodnog i hemijskog porekla za suzbijanje
glodara u usevima lucerke i pšenice.
Eksperimenti su izvedeni prema standardnoj metodi OEPP/EPPO. Ogled je postavljen
po potpuno slučajnom blok sistemu, sa četiri ponavljanja i veličinom osnovne parcele od
400 m2. Obeležja koja su praćena tokom ovog ispitivanja su prosečna brojnost aktivnih rupa
i efikasnost rodenticida u vremenu od tri, sedam, 14 i 28 dana. Brojnost glodara je izračunata
na osnovu broja aktivnih rupa, a efikasnost rodenticida prema Abbott-ovoj formuli.
Na osnovu izgleda i prostornog rasporeda aktivnih rupa utvrđeno je prisustvo poljske
voluharice (Microtus arvalis Pall) i poljskog miša (Apodemus agrarius) na eksperimentalnim
parcelama. Testirani preparati pokazali su zadovoljavajuću efikasnost u suzbijanju glodara
u usevima lucerke i pšenice. Preparati na bazi vitamina D3, u oba useva, pokazali su efikasnost
87-90%. Efikasnost preparata na bazi bromadiolona bila je u intervalu 84-90%, dok
je preparat na bazi celuloze pokazao najveće oscilacije i njegova efikasnost je bila u intervalu
86-98%.
