Abstract

Control of chickweed (Drymaria cordata) in declining tropical pastures.

Abstract

On the Atherton Tableland D. cordata is an increasing problem in irrigated pastures. Fenoprop propylene glycol ethyl ester or the butyl ester at 1.68-2.24 kg/ha + 0.1% non-ionic wetter has given satisfactory control. No advantage was gained by raking off dead plant material after treatment. Tinaroo glycine (Glycine wightii) was severely damaged by fenoprop. Cultivation appeared as effective as fenoprop in controlling D. cordata, while under non-irrigated conditions a dry spring season was sufficient to suppress the weed.
