Stream Restoration Effectiveness In Mullins Creek In Fayetteville, Arkansas, Amadeo Scott, Shannon Speir

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

Evaluating Efficiency And Accuracy Of Three Texture Analysis Methods For Blackberry Fruit, Rhys M. Brock, Carmen Johns, Katelyn Lust-Moore, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A major objective of the University of Arkansas System Division of Agriculture (UADA) Fruit Breeding program is to improve the texture of blackberry (Rubus subgenus Rubus Watson). Blackberry varieties with improved fruit firmness transport and store well and may maintain superior quality under challenging postharvest conditions than softer varieties. Increased firmness may also make cultivars less susceptible to red drupelet reversion (RDR), a postharvest disorder of blackberries in which fully black drupelets revert to red after harvest. This research project aims to assess the efficiency and accuracy of three methods applied in evaluating blackberry firmness. The study compares instrumental analysis …

Wa Insecticide Guide 2024 - Winter Spring, Svetlana Micic, Alan Lord

PestFacts WA

The insecticides listed in the tables within this guide can be used on any crop appearing on the chemical label, if the rate used does not exceed the highest rate that is registered for use on that crop.

There are many products with different trade names that contain the same active ingredient. This list is not exhaustive and does not imply any specific recommendations of brand names.

Evaluation Of Water Hardness And Ph On Soybean And Cotton Insecticide Efficacy, Taylor Davis

Graduate Theses and Dissertations

Insecticide efficacy often varies by location and year. Many factors can influence an insecticide’s efficacy, but an often-overlooked factor is the quality of water in a carrier solution. Water quality includes many parameters, but two important ones are water hardness and pH. Research has shown that water hardness and pH can affect some pesticides. Multiple experiments were conducted to evaluate the impact of water hardness and pH on insecticide efficacy. Experiments were conducted to evaluate the impact of water hardness and pH on the efficacy and residual control of chlorantraniliprole for the control of corn earworm, Helicoverpa zea (Boddie). Leaf …

Efficacy Of Biocontrol Against Chrysomelid Pests In Lab Vs Field Studies: Potential Biases Of Setting And Phylogenetic Subgroups, Blake Hudson

2023 Midwest Ecology & Evolution Conference

The beetle family Chrysomelidae is a speciose group of voracious herbivores with a wide number of ecological implications. While some Chrysomelid species have been introduced or augmented as biological control agents of invasive plants, many other species have found success as economically important pests of field crops and stored grains, leading to severe yield losses in cucurbits, legumes, and other systems. Controlling such pests, especially in the field, is particularly difficult due to the timing of their complex life cycles, the fossorial nature of many species’ larvae, and ability to produce multiple generations in a single growing season. This study …
