Extending Knowledge On Biosecurity In Small-Scale And Backyard Systems In The United States, Juliette Di Francesco, Amber Itle, Craig Mcconnel, Ragan Adams, Roselle Busch, Richard Van Vleck Pereira, Terry W. Lehenbauer, Beatriz Martínez-López, Alda F. A. Pires

Journal of Extension

The number of small-scale and backyard operations has increased in the United States during the past decade, but there is currently a lack of outreach efforts and readily-available educational materials targeting these farming systems. We developed a webinar series on biosecurity to provide training for small-scale and backyard producers, and training tools that can be used by local veterinarians and extension educators to disseminate knowledge and consistent recommendations more effectively. Fewer people attended the webinars than registered, suggesting a gap between interest in biosecurity and commitment to the topic. Participants in the webinar series reported a high level of satisfaction …

Modelling The "Bottom-Up" Development Pattern Of Tar Spot Disease In Corn, Brenden Lane, Joaquín Guillermo Ramírez-Gil, Carlos Góngora-Canul, Mariela Sofia Fernandez Campos, Andres Cruz-Sancan, Fidel E. Jiménez-Beitia, Alex G. Acosta-Guatemal, Wily Sic, C. D. Cruz

Graduate Industrial Research Symposium

In 2015, the corn-infecting pathogen Phyllachora maydis (causal agent of tar spot disease) was reported for the first time in the United States. The disease has since spread across the US, causing major yield losses. In 2021 alone, 5.88 million metric tons (231.3 million bushels) of US corn yield were lost to this disease, costing an estimated US$1.25 billion. Though fungicides can protect against these agroeconomic losses, application timing can be difficult to optimize because our understanding of tar spot dynamics is still evolving. The current view is that tar spot typically develops bottom-up through a repeating infection cycle. Because …

A Spatio-Temporal Modelling Approach To Understand The Effect Of Urban Fruit Fly Outbreaks On Peri-Urban Orchards, Andrew Broadley, Rieks Van Klinken, Dean R. Paini, Matthew Hill, Elliot T. Howse

Horticulture Research Articles

Urban areas are well-known sources of fruit fly introduction and unmanaged populations pose a high risk of dispersal to surrounding agricultural areas. Although management of urban fruit fly populations is recognised as being important for area-wide control programmes, its relative importance is rarely quantified. Identifying possible sources of fruit fly populations is important to the success of area-wide programs, as well as to on-farm management. We developed a modelling approach to analyse the spatio-temporal connectivity of fruit fly across urban-agriculture boundaries. For a case study, we examine Mediterranean fruit fly, Ceratitis capitata, outbreaks in two fruit growing …

Burial And Subsequent Growth Of Rigid Ryegrass (Lolium Rigidum) And Ripgut Brome (Bromus Diandrus) Following Strategic Deep Tillage, Catherine Borger, George Mwenda, Sarah Collins, Stephen Davies, Arslan Peerzada Dr, Andrew Van Burgel

Biosecurity Research Articles

Soil amelioration via strategic deep tillage is occasionally utilised within the conservation tillage systems to alleviate soil constraints, but its impact on weed seed burial and subsequent growth within the agronomic system is poorly understood. This study assessed the effects of different strategic deep tillage practices, including soil loosening (deep ripping), soil mixing (rotary spading), or soil inversion (mouldboard plough), on weed seed burial and subsequent weed growth, compared to a no-till control. The tillage practices were applied in 2019 at Yerecoin and Darkan, Western Australia, and data on weed seed burial and growth was collected during the following three-year …

Australian Cool-Season Pulse Seed-Borne Virus Research: 1. Alfalfa And Cucumber Mosaic Viruses And Less Important Viruses, Roger A C Jones, Benjamin S. Congdon

Biosecurity Research Articles

Here, we review the research undertaken since the 1950s in Australia’s grain cropping regions on seed-borne virus diseases of cool-season pulses caused by alfalfa mosaic virus (AMV) and cucumber mosaic virus (CMV). We present brief background information about the continent’s pulse industry, virus epidemiology, management principles and future threats to virus disease management. We then take a historical approach towards all past investigations with these two seed-borne pulse viruses in the principal cool-season pulse crops grown: chickpea, faba bean, field pea, lentil, narrow-leafed lupin and white lupin. With each pathosystem, the main focus is on its biology, epidemiology and management, …

Pest Slugs And Snails And Their Management In Broadacre Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Slugs and snails cause damage to all broadacre crops. Numbers of slugs and snails have increased in broadacre cropping in Western Australia (WA) with the use of minimum tillage and stubble-retention practices. These systems increase the organic content of paddocks and soil moisture content, leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly in the Mediterranean region. They have similar lifecycles, which means similar management techniques can be employed to control them in broadacre crops.

Effective management requires application of controls that coincide with different phases of the …

Powdery Mildew And Its Management In Wheat, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Powdery mildew is a fungal leaf disease that reduces yield and grain quality in susceptible wheat varieties. Disease is both stubble-borne and carried over on green bridge (secondary spread by wind borne spores). It has multiple, fast life cycles in a growing season and can be difficult to control once established. The best approach is an integrated disease management strategy.

With wheat area in Western Australia dominated by susceptible varieties, such as Scepter, powdery mildew remains a concern for growers statewide and has been particularly persistent and damaging in the Esperance Port Zone.
