Monks, Stephen L. Meyers, David L. Jordan, Jonathan R. Schultheis, David H. Suchoff, Levi D. Moore, Stephen J. Ippolito

Department of Horticulture & Landscape Architecture Faculty Publications

Flumioxazin and S-metolachlor are widely used in conventional sweetpotato production in North Carolina and other states; however, some growers have recently expressed concerns about potential effects of these herbicides on sweetpotato yield and quality. Previous research indicates that activated charcoal has the potential to reduce herbicide injury. Field studies were conducted in 2021 and 2022 to determine whether flumioxazin applied preplant and S-metolachlor applied before and after transplanting negatively affect sweetpotato yield and quality when activated charcoal is applied with transplant water. The studies evaluated five herbicide treatments and two activated charcoal treatments. Herbicide treatments included two flumioxazin rates, one …

Horticulture Faculty Publications and Presentations

Spring dead spot (Ophiosphaerella spp.; SDS) is one of the most detrimental diseases to warm-season turfgrasses, particularly bermudagrass (Cynodon spp.), growing in climates where cold temperatures induce dormancy. The pathogen can infect the crowns, stolons, rhizomes, and roots of bermudagrass most of the year, but infection in the fall predisposes the turf to winter injury and plant death. Symptoms typically appear the following spring, making management of SDS challenging. Moreover, the biology, epidemiology, and management of SDS are not fully understood. Ample research has been conducted on SDS which was thoroughly summarized before 2009 by Tredway et al. …

Buzzworthy Messaging: Assessing Residents’ Perceptions Of Labels To Better Promote Pollinator Gardening, Colby J. Silvert, Laura A. Warner, Cody Gusto, John M. Diaz, Rachel E. Mallinger

Journal of Extension

Consumers appear more likely to purchase plants with labeling indicating pollinator-friendly production or high pollinator resource value. No standardized label for pollinator-supporting plants or landscape practices exists in the United States, which has proliferated the variety of labels used by the industry. This mixed-methods study aims to provide insight into residents’ preferred pollinator-related labelling for plants and landscape practices in order to help Extension professionals and green industry stakeholders improve outreach, marketing, and communications efforts. Findings suggest a butterfly-friendly label would be most effective for marketing while residents would accept and favorably perceive labels emphasizing either pollinator-friendly or bee-friendly attributes.

Abstract

Bermudagrass (Cynodon spp. Rich) is a warm-season grass that is widely planted throughout tropical, sub-tropical, and even temperate climates, and it generally requires fewer inputs than most cool-season turfgrasses. In recent years, the area of adaptation for bermudagrass has progressively expanded to cooler climates due to the development of more cold-tolerant cultivars. The expanded area of adaptation as well as the reduced inputs required to maintain healthy turfgrass have made bermudagrass a popular choice in areas of marginal adaptation. In these areas, the greatest threat to bermudagrass health and survivability is winterkill. This management guide seeks to describe …

Association Mapping Of Important Agronomic Traits In Mucuna Pruriens (L.) Dc., Patrush Lepcha, Mahesh Shekhar, Leelambika Murugesan, Mahammad Jaheer, Ratan Chopra, Vikas Belamkar, Narayana Sathyanarayana

Department of Agronomy and Horticulture: Faculty Publications

Background The tropical legume Mucuna pruriens (L.) DC. can meet three agricultural needs: low-cost protein, highvalue medicines, and green manure or cover crops. But like other underutilized crops, it needs more modern breeding resources. Identifying marker-trait associations (MTAs) can facilitate marker-assisted breeding and crop improvement. Recent studies have demonstrated the feasibility of identifying MTAs using a small number of accessions (< 100). We have characterized a panel of 70 M. pruriens accessions across two consecutive years and performed association analysis for 16 phenotypic traits related to seed (seed length, seed width, seed thickness, seed yield per plant, hundred seed weight); pod (pod length, pod width, number of pods …

Key Stages In The Growth And Maturity Of Field Pea, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Many farm operations rely on a clear understanding of the stage of crop development. This factsheet describes key growth stages of field pea, which will aid growers and their advisers in determining the appropriate timing for the application of herbicides, crop-topping, swathing, and harvest.

There is likely to be considerable variability in a crop, particularly at maturity and harvest. Therefore, it is often necessary to estimate the average or majority development stage of a crop. At first, this is best done numerically, but with experience it can be done by eye.
