Summary

The use of imazethapyr as a sprout suppressant in potatoes has been investigated. Novel radionuclide techniques were developed to establish the patterns of uptake and movement of imazethapyr in potatoes. Protocols for tissue analysis were established to homogenise potato tuber tissue samples, enabling radiolabel recovery by liquid scintillation counting to approach 100%. The movement of imazethapyr was also examined in the presence of an acidic formulation of thiabendazole which caused increased uptake. The movement of imazethapyr within the tuber was also influenced by pH and ion trapping.
