Living Heritage, Resilience And Ethically Informed Infrastructures In Malawi, Martha B. Lerski, Frank Puluputu Mwale

Publications and Research

Rooted in a rural community’s needs, this paper explores how historically, and ethically informed infrastructures can support community engagement towards identification, documentation, and dissemination of local, traditional, and indigenous knowledge relating to climate change. The paper examines climate adaptation and sustainability issues through the lenses of community organizing and Library & Information Science best practices. It draws on a growing body of literature identifying a role for expanded epistemological and subject discipline perspectives. While the impacts of climate on material culture are increasingly recognized, intangible, and biocultural heritage have not received as much attention. Living heritage traditions and knowledge systems …

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

Capeweed And Its Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Capeweed (Arctotheca calendula) is a prostrate, stemless, sprawling annual herb that germinates during autumn and winter. In Western Australia (WA), competition from 7 to 90 capeweed plants per square metre in a wheat crop can reduce crop yield by 28 to 44% and net return by 25 to 76%.

Diamondback Moth And Its Management In Canola And Crop Weeds, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Diamondback moth larvae are a serious pest of canola, brassicas, and forage crops, and are difficult to control. The pest breeds up on summer weeds and volunteer canola plants. If there are abundant early rains and mild winters, diamondback moth larvae pose a risk to canola crops.

Are You Planting Resistant Weeds With Your Crop Seed?, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Key messages

• West Australian (WA) grain growers have significant weed seed contamination in their crop seed.

• WA growers are sowing herbicide resistant weed seed into their cropping paddocks.

• Crop hygiene (harvest, seeding, transporting) is important to minimise spread of weeds.

Harvest is well underway throughout the WA grainbelt, and growers will be harvesting grain and collecting seed for next year’s crop.

However, this crop seed can be contaminated with weed seeds and, if seed cleaning operations are only partially effective, this weed seed may be sown into paddocks with crop seed in the following season.

Button Grass And Its Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Button grass (Dactyloctenium radulans) is a native species found throughout Australia. It is a common summer weed species that depletes soil moisture and nutrients, reducing the yield potential of the subsequent crop. It also acts as a green bridge for crop pests and disease.

The rapid emergence and growth of button grass after rainfall makes it important for the Australian plague locust.

It can be a valuable pasture species in arid areas, although overgrazing of button grass can result in toxicity for sheep and cattle.

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

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.

Use Of Acetolactate Synthase-Inhibiting Herbicides In Inzen Grain Sorghum (Sorghum Bicolor L. Moench Ssp. Bicolor), Hunter Bowman

Graduate Theses and Dissertations

Grain sorghum is typically grown as a rotational crop in Arkansas because of its many benefits, one being the effective control of Palmer amaranth through the use of atrazine. However, limited options exist for postemergence (POST) control of weedy grasses within the crop. Inzen™ grain sorghum is the result of a nicosulfuron resistant weedy sorghum biotype cross-bred with a commercial line of grain sorghum. Inzen™ allows for safe use of over-the-top applications of nicosulfuron within the crop. Nicosulfuron is an acetolactate synthase (ALS)-inhibiting herbicide, which has historically been used in corn for control of weedy grasses. Experiments were conducted in …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer

Journal of Applied Farm Economics

This study evaluated the feasibility of reintroducing mechanical weed control as an alternative for herbicide-resistance weed infestations. The production practice tested included row cultivation with a separate banded spray application using high-accuracy automated guidance systems. A range of ground speeds were tested for the row cultivation operation, each with a different per acre cost and timeliness penalty. A typical eastern Corn Belt farm with a rotation of corn and soybean served as the base for the linear programming model. It was found that if the farmer was willing to reintroduce tillage, row cultivation conducted at higher operating speeds in conjunction …
