Field studies were conducted in North Carolina to determine the critical period of weed control (CPWC) for Italian ryegrass winter wheat. Soft red wheat was planted late fall 2017 and 2018 no-till fields near Salisbury, NC. Treatments consisted allowing weeds grow from crop emergence different intervals until removal (“weedy”), maintaining “weed-free” conditions same intervals, then letting emerge compete with duration season. In 2017, occurred two-week up 18 weeks after (WAE) three-week WAE...
Abstract Root-knot nematodes (RKN; Meloidogyne spp.) are among the most damaging plant-parasitic nematodes. They parasitize almost every species of higher plant and induce formation galls along roots, which detrimental to growth. North Carolina’s leading field crops sweetpotato ( Ipomoea batatas (L.) Lam.), soybean Glycine max L. Merr), cotton Gossypium hirsutum L.), tobacco Nicotiana tabacum all hosts several root-knot nematode species. This pathogen represents a major threat farmers,...
Industrial hemp (Cannabis sativa L.) has recently been reintroduced as an agricultural commodity in the United States, and, through state-led pilot programs, growers and researchers have investigating production strategies. Diseases disorders of industrial States are largely unknowns because record-keeping taxonomy improved dramatically last several decades. In 2016, North Carolina launched a program to investigate hemp, diseases abiotic were surveyed 2017 2018. Producers, consultants,...
Abstract Lesser celandine ( Ranunculus ficaria ) is an ephemeral perennial introduced to North America from Europe for ornamental use. This species becoming widespread in shady, moist woodlands and lawns the northern United States southern Canada. Despite its invasive attributes, lesser continues be marketed by nursery sector. A hardy easy plant grow, has a dense compact growth form that makes it ideal border plantings showy flowers make desirable garden early spring color. The easily...
Bittercress (Brassicaceae) is one of the most prolific and costly weeds container nursery industry. accessions from nurseries throughout major production zones in United States were examined compared with herbarium specimens. The identity these weedy bittercress species further explored using sequences nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) region nrDNA for COP1-interacting protein 7 ( CIP7 ). Four detected industry States, including New Zealand bittercress, hairy...
Carinata (Brassica carinata A. Braun) is an emerging oilseed crop with potential as a dual use winter cover/cash in the southeastern US region. Although historically cultivated spring northern latitudes, incorporating into cropping systems can provide winter/cover ecosystem services and bio-feedstock for high value, renewable aviation fuel without displacing feed food crops. In this study, our major objective was to quantify agronomic performance stability of selected genotypes across...
Abstract Planting date can affect crop yield and is an important management decision for practitioners. Although wheat ( Triticum aestivum L.) soybean [ Glycine max (L.) Merr.] be effectively double‐cropped in North Carolina, if commodity prices projected economic returns are higher crops other than soybean, growers might consider a nontraditional, double‐crop system. Direct comparisons of major agronomic with different planting dates or system limited Carolina. Therefore, research was...
Abstract Field experiments were conducted from 2017 to 2019 determine the tolerance of carinata several preemergence and postemergence herbicides. Preliminary screenings identified herbicides that caused large variation on injury, indicating potential for selectivity. Dose-response field studies quantify select Diuron applied at rates 280 g ai ha −1 or higher reduced population density 54% 84% compared nontreated control. In certain locations, clomazone minor injury with an acceptable level...
Many abiotic factors impact the yield and growth of Brassica carinata (commonly referred to as or Ethiopian mustard). Very little is known about how mineral nutrients its growth, more specifically, sufficiency values for fertility over plant’s cycle life stages. This study explored impacts that plant nutrients, specifically micronutrients, can have on development distinct stages (rosette, bolting, flowering, pod set). Plants were grown under varying micronutrient concentrations (0, 25, 50,...
ABSTRACT Field studies were conducted in 2016 and 2017 at two locations North Carolina to evaluate common ragweed (Ambrosia artemiisifolia L.) (Lewiston-Woodville) Palmer amaranth (Amanthus palmeri S. Wats) control (Rocky Mount), peanut (Arachis hypogaea yield, estimated economic return when herbicides applied postemergence (POST) 2 or 6 weeks after planting (WAP); 4 WAP; 2, 4, WAP. During the following growing season, cotton (Gossypium hirsutum was planted directly into same plots determine...
Silvery threadmoss naturally reproduces through spore and bulbil production, both of which have potential to be controlled prior establishment. Studies not evaluated effects turf protection products on moss protonema or gametophyte growth from spores bulbils; consequently, most is POST putting greens. Initial studies were performed determine the optimal temperature for bulbils in sterile culture. Protonemata grew optimally at 29.5 C gametophytes 22.5 C. Three subsequent vitro conducted...
Field experiments were conducted at two locations in North Carolina (Clayton and Rocky Mount) to determine the influence of row spacing planting date on critical period weed control (CPWC) grass weeds ALS-tolerant grain. Grain sorghum was planted May June 2019, with either a 38 or 91 cm using an variety. Treatments consisted “weedy” “weed-free” plots up 2, 3, 5, 7 weeks after crop (WAP) treatments weedy weed-free all season. Selection species achieved by controlling broadleaf premix...
Core Ideas Different wheat residue management strategies were evaluated for winter canola survival and yield. Plant stand declined during the course of growing season all treatments. crown height data showed significant differences among treatments; however, inconsistent. This study that conservation tillage did not significantly impact yield canola. suggests analysis is indicative final data. The integration in southern Great Plains has allowed producers to diversify their cropping systems...
Abstract Adequate weed control is important in protecting crop yield and allowing efficient harvest North Carolina. Data the literature are limited with respect to direct comparisons of across multiple crops. Research also terms documenting impact one on populations planted following season. Experiments were conducted Carolina determine corn ( Zea mays L.), cotton Gossypium hirsutum soybean [ Glycine max (L.) Merr.] same experiment when herbicides applied postemergence at different timings...
New Zealand bittercress is reported as new to the United States. While collecting specimens determine what Cardamine species occur in nursery trade, was discovered a container Wilkes County, North Carolina. The tracked shipment of contaminated plants wholesale Washington Oregon. It subsequently confirmed that also occurs Clackamas Oregon, and has likely been distributed throughout States contaminant grown ornamental plants. Thus far there have no reports naturalized populations outside crop...
Abstract As a recently introduced crop in the United States, there are limited data regarding temporal nutrient accumulation and partitioning dynamics of Brassica carinata (carinata). A four site‐year study was conducted Jay, FL Salisbury, NC during 2018–2019 2019–2020 growing seasons. Three genotypes (DH‐157.715, M‐01, Avanza 641) proposed by industry to represent early‐, mid‐, full‐season genotypes, respectively, were sampled at multiple growth stages partitioned into leaves, stems,...
