Brome Grass Population Dynamics In Relation To Control Systems, A. H. Cheam Jan 1990

Brome Grass Population Dynamics In Relation To Control Systems, A. H. Cheam

Experimental Summaries - Plant Research

Developing crop rotation systems for controlling brome grass.

Over the last four years the population dynamics of brome grass in various crop and pasture rotation systems have been monitored with the following aims.

To identify the level of control of brome grass under various rotation systems, so that farmers can be advised on the degree of infestation likely to be encountered when using a particular system.

To design the best control to reduce quickly the anticipated large seed population of brome grass in the soil.

To determine whether the persistence of brome grass is related more to survivors shedding seeds …

Experimental Summaries - Plant Research

Trial 90C49

Grass and broad leaved weed control in direct sown crops.

Biological Control Of Doublegee, Dane Panetta Jan 1990

Biological Control Of Doublegee, Dane Panetta

Journal of the Department of Agriculture, Western Australia, Series 4

Doublegee (Emex australis) is one of the worst agricultural weeds in Western Australia. To date, however, biological control of this weed has proved elusive. Multiple releases of two weevils which attack doublegee have not led to insect establishment. For one of these species, further research has shown that doublegee control would probably not be achieved in the wheatbelt even if insect establishment were enhanced by growing its host during the summer months. A joint Western Australian Department of Agriculture/ CSIRO project is investigating the virulence and host specificity of an undescribed South African species o/Phomopsis fungus. Should this pathogen prove …

Pursuit For Weed Control In Peas., S. Curtin

Experimental Summaries - Plant Research

All trials were located in Merredin.

Trial 90ME86

This trial was one of the best demonstrations of pursuits effectiveness against mustard in particular. Other weeds were rough poppy and ryegrass and a small amount of cereal and doublegee.
