Avian Choice Test
Summary
Avian choice test of a repellent used for maize seed treatment
Contracting entity: EDEN Research plc
Contracted entity: University of Castilla-La Mancha
“Ecovelex™ has a clear repellent effect when used as maize seed treatment at its proposed application rate and also at 50% of that rate.
This effect is noticeable when treated seed availability is similar to that of untreated seeds, although the effect becomes more subtle as untreated seeds become less available and therefore the relative availability of treated seeds grows.
Consequently, after 24 h, and despite partridges had enough alternative food (fodder) to satisfy their daily demands, there was no difference in consumption of treated or untreated seeds.
In general, consumption of Ecovelex (at its recommended application rate) by partridges seemed to occur only under scenarios in which animals were running out of alternatives, and even if there were no significant differences at the end of the trials, treated seed consumption did not reach the same levels as ingestion of untreated seeds.“
