Abstract

A method is described whereby the release of chlorpropham, or isopropyl-N-(3-chlorophenyl) carbamate (CIPC), from a formulation with alumina as carrier can be evaluated by a biological assay involving the measurement of root length of cress (Lepidium sativum L.). Several additives were identified which limit the release of CIPC. Formulations with Tween 20 (15% w/w) and Triton X-114 (15% w/w) as additives were found to produce consistently lower release rates of CIPC than a corresponding formulation without additive. The lowering of the release rate should enhance potato sprout suppression at high temperatures and this was confirmed in a 10 kg box-scale storage experiment.
