To assess the efficacy of imidacloprid applied at varying rates
Imidacloprid is continually being detected in local waterways at above threshold levels. One way of reducing this value is to close the application channel using a stool zipper. This project will compare water quality from locations using a stool zipper.
This trial uses two treatments, one applied in an opening in the soil followed by the closing of the opening using a stool zipper and one applied in an opening in the soil with no closure. The stool zipper is a device that travels behind the applicator and closes the application channel over thereby reducing the risk of water entering the application channel causing imidacloprid to be transported out of the paddock.
