Promoting best management practice for weed control in Central West New South Wales

摘要

The Central West cropping zone of New South Wales (NSW) is unique in its rainfall pattern and weed spectrum. Little weed management information is available for this zone as weed spectrums and management approaches from the northern and southern cropping areas do not always apply. For this reason, a manual has been produced focusing on best management practice for weed control in these farming systems. Best management practice for this cropping zone includes crop, fallow and pasture agronomy as wellas specific management solutions for the weed spectrum present. Best management practice also needs to consider the effective use of herbicides with respect to herbicide choice and application. Biological control is helping manage major weeds in the Central West such as Paterson's curse (Echium plantagineam L.) and horehound (Marrubium vulgare L.) and can be integrated as part of the farm management system. Herbicide resistance is not yet been widespread in the area. Managing herbicide rotations alongside crop and pasture rotations is a major part of preventing herbicide resistance. Drought and crop availability are limiting factors in effective rotations for long term weed control. The manual has combined the latest research, knowledge of the region'sdistrict agronomists and the experiences of successful farmers. The manual provides information on weed ecology and agronomy, allowing the farmer to assess their own situation and to develop a custom based system that suits their individual situation.
