Barley Grass And Its Management In Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Barley grass is a common name for Hordeum glaucum and H. leporinum. Barley grass is a major crop weeds species because the seed is readily dispersed, it is renowned for rapidly germinating in autumn, and post-emergent herbicide control options are limited. It can also act as an alternate host for cereal diseases and can develop resistance to herbicides.

The rapid germination of the species after rainfall gives barley grass the potential to act as a green bridge for cereal root rot diseases

Managing Crop Weeds, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

In-crop weed competition causes losses costing around $1 billion per annum for Western Australia. There are effective strategic and tactical options available to manage weed competition that will increase crop yields and profitability.

Weeds with herbicide resistance are an increasing problem in grain cropping enterprises. Integrated weed management (IWM) is a system for managing weeds over the long term and is particularly useful for managing and minimising herbicide resistance.

Growers are advised to adopt integrated weed management (IWM) to reduce the damage caused by herbicide-resistant weeds.

Herbicide resistant weed populations are found throughout all cropping areas of Western Australia. The …

Brome Grass And Its Management In Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Brome grass (Bromus spp.) is one of the most competitive grass weeds in wheat. Over the last 10 years, brome grass has increased in importance to a greater extent than any other weed species in Australia.

Recent changes in crop production systems, increased conservation tillage, a lack of available selective herbicides, and a decline in system diversity have seen an increase in the importance of this weed in Western Australia (WA).

Seed is the main source of brome grass infestation and, as few seeds remain dormant, the most important aspect of management is to reduce its seed bank.

Annual Ryegrass And Its Management In Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia. It is highly competitive and can compete with a crop as early as the 2-leaf stage.

Annual ryegrass is a winter to spring growing weed that can emerge from late autumn to early spring. The number of emergence flushes and the density of plants that emerge are related to initial seedbank levels and the frequency and amount of rainfall.

Field Evaluation Of Female- And Male-Targeted Traps For Ceratitis Capitata (Diptera: Tephritidae), Elliot T. Howse, Rieks Van Klinken, Nicholas J. Beeton, Helen Spafford, Kim P. James, Matthew P. Hill

Horticulture Research Articles

Mediterranean fruit fly (Medfly) Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is a globally significant economic pest for which lure based trapping can be used to monitor established populations and for surveillance. Either female- or male-targeted traps can be used; however, recommendations on which to apply are inconsistent and many programs rely on male-targeted traps. Here, we compare the performance of male-targeted traps (Lynfield Trap with Trimedlure) and female-targeted traps (Biotrap Globe trap with the 3-component lure—TMA Plus) in apple orchards in south-west Western Australia over 2 years (September 2019 to September 2021). Male-targeted traps caught more Medflies overall than female-targeted traps, …

Manage Crop Weeds At Harvest, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

This management strategy provides an opportunity to control weed seed set in the pasture and during harvest. The strategy physically removes viable seed from the paddock by collecting weed seed and grazing crop residues.

Weed seed removal at harvest can be achieved in 2 ways:

1. collecting weed seeds from the system to prevent them being spread across the paddock or farm

2. grazing weed contaminated crop residue and pastures.

Assessing Health Implications Of Monarch Butterfly Populations And Behaviors, Kira Goldman, Kelsey E. Fisher Dr.

Honors Scholar Theses

Pollinator populations have seen massive declines over the past decade due to anthropogenic activity and climate change posing serious threats to the health of humans and ecosystems (Ulyshen & Horn, 2023). As agents responsible for the production of about 35% of micronutrient rich food crops necessary for adequate nutrition to lead healthful lives and prevent nutrition associated diseases, pollinator decline is a public health concern (Aizen et al., 2009). Monarch butterflies (Danaus plexippus) serve as bio indicators for the health of pollinator populations because of their analogous habitat and food resources shared with many other pollinator species, including bees and …
