Industrial Hemp

Hemp (Cannabis sativa) or industrial hemp is a rapidly growing industry in the United States. However, the crop has been poorly studied in the US since its production declined in the late 1950s, and information on the biological and agricultural factors affecting hemp is limited. With the passage of the 2014 Farm Bill, hemp is no longer considered an illegal plant and is now a legal agricultural crop in the US. Within the bill, Section 7606 (Legitimacy of Industrial Hemp Research) provided a formal definition of the crop as "the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9-tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis". In addition, the 2018 Farm Bill addressed many issues that had previously impeded development of the crop. Currently, 46 US states have enacted laws removing barriers to its production. In 2019, hemp production was 206, 965 hectares with 16,877 grower licenses across 34 states, according to "US Hemp Report" (www.votehemp.com). This is a greater than 455% increase over 2018 licensed acreage. Colorado, the leading state in hemp production increased production from 4,873 licensed hectares (346 growers) in 2017 to 12,525 licensed hectares (835 growers) in 2018. The US retail sales of hemp products was reported at $1.2 billion in 2018. The most profitable market for North American hemp is oilseed production and cannabidiol (CBD), a nonintoxicant cannabinoid with promising therapeutic use as a pharmaceutical product. Current CBD sales are estimated at $190 million and are projected to reach $2.5 billion by 2022. As we enter this new era of hemp production, plant diseases associated with the crop in the US and associated disease management needs are essentially undescribed. The emergence of phytopathogens and their spread is a rising concern as hemp production increases. Therefore, there is an urgent need to identify emerging and established hemp viruses and viroids, elucidate their diversity and distribution, develop early pathogen detection tools, and provide hemp growers, industry and other stakeholders information and resources to make timely management decision and minimize crop loss.

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 been investigating production strategies. Diseases and disorders of industrial hemp in the United States are largely unknowns because record-keeping and taxonomy have improved dramatically in the last several decades. In 2016, North Carolina launched a pilot program to investigate industrial hemp, and diseases and abiotic disorders were surveyed in 2017 and 2018. Producers, consultants, and agricultural extension agents submitted samples to the North Carolina Department of Agriculture and Consumer Services Agronomic Services Division (n = 572) and the North Carolina Plant Disease and Insect Clinic (n = 117). Common field diseases found included Fusarium foliar and flower blights (Fusarium graminearum), Fusarium wilt (Fusarium oxysporum), and Helminthosporium leaf spot (Exserohilum rostratum). Greenhouse diseases were primarily caused by Pythium spp. and Botrytis cinerea. Common environmental disorders were attributed to excessive rainfall flooding roots and poor root development of transplanted clones.

Abstract Background In 2018, the Farm Bill mandated the United States Department of Agriculture to develop regulations governing the cultivation, processing, and marketing of industrial hemp. Industrial hemp is defined as Cannabis sativa L. with a total Δ-9-tetrahydrocannabinol (Δ-9-THC) content ≤0.3%. Therefore, for hemp to become an agricultural commodity, it is important to regulate production by developing standard methods for sampling and testing of the plant material. Methods An ultra-performance liquid chromatography-tandem mass spectrometry analytical method for the quantification of twelve cannabinoids was developed. The method was applied to a regulatory sampling trial of three hemp varieties cultivated for cannabidiol (CBD) production. Two samples were taken from 28 plants with one sample being flower only while the other was a composite sample that included flowers, leaves, and stems. Results The assay method was validated for specificity, range, repeatability, reproducibility, and recovery in accordance with all applicable standards for analytical methods. The results of the regulatory study indicated a significant decrease in the concentration of total Δ-9-THC and total CBD of 0.09% and 1.32%, respectively, between a flower only and a composite sample. Conclusions There are many factors that may influence reported total Δ-9-THC content in industrial hemp. A robust analytical method was developed to analyze hemp samples in a trial regulatory study. The results indicate that the way hemp is sampled and analyzed may influence the legality of a crop, which could have negative economic and legal consequences.

This review paper gives an overview of Cannabis Sativa, also known as hemp, which has been cultivated and used century's B.C. due to its medical, hallucinogenic and agricultural properties. Cannabis has been described in 1938 as the billion-dollar plant but has lost its value in the U.S. due to regulatory and legislative issues. Hemp has seen as new push In the U.S. with the introduction of the 2018 Farm Bill which allows on a federal level to grow hemp, pending on individual state regulations. Currently, industrial hemp production is allowed in at least 38 U.S. States under strict regulations. Today hemp is used in counties that do not have as strict regulations as the U.S. in a variety of applications such as beauty products, carpets, cooking oil, personal care products and textiles. Hemp can be considered as an alternative feedstock due to its low lignin and high cellulose level for biofuel application as an alternative to replace petroleum-based fuels and gases. In the U.S. hemp research in these areas has stalled due to the complexity of the law. Beside industrial application such as ropes, textiles, shoes, etc., hemp today is used in pharmaceutical and medical applications, by extracting Δ9-tetrahydrocannabinol and cannabinoids from the leaves and fluorescence of the hemp plant that contain no more than of up to 0.3% of these compounds. The use of hemp plants with higher levels are strictly forbidden in most countries. Several extraction processes of cannabinoids from hemp are used They all use a solvent for extraction but differ in terms of efficiency, usage range and other factors influencing the extraction. Nonetheless, overconsumption of cannabis products can be associated with several side effects, that can cause serious physiological and psychological damage in the human body may cause serious damage.

AbstractAccurate understanding of the global spread of emerging viruses is critically important for public health response and for anticipating and preventing future outbreaks. Here, we elucidate when, where and how the earliest sustained SARS-CoV-2 transmission networks became established in Europe and the United States (US). Our results refute prior findings erroneously linking cases in January 2020 with outbreaks that occurred weeks later. Instead, rapid interventions successfully prevented onward transmission of those early cases in Germany and Washington State. Other, later introductions of the virus from China to both Italy and Washington State founded the earliest sustained European and US transmission networks. Our analyses reveal an extended period of missed opportunity when intensive testing and contact tracing could have prevented SARS-CoV-2 from becoming established in the US and Europe.

Industrial hemp (Cannabis sativa), has been proposed as a new crop that might be of interest to organic farmers in the North Carolina and other states in the United States. However, little is known about how organic farmers view this crop. We conducted a survey among North Carolina certified organic growers to ascertain their knowledge of, and willingness to adopt, industrial hemp. Contact information was obtained from a database of certified organic farmers in North Carolina and the growers were contacted by email and directed to complete an online questionnaire. Growers were asked a wide range of questions about farm characteristics, technology adoption, interest toward industrial hemp, and policy issues regarding hemp adoption. A total of 245 farmers were contacted; 64 started the survey and 35 responded to all questions. Our results indicate that 85% of North Carolina organic growers are interested in growing hemp on their farms and the majority wanted to learn more about the crop production practices, adapted cultivars, and legality of growing it. Seventy-five percent expressed interest in being certified growers while 52% wanted to grow industrial hemp primarily for cannabidiol (CBD) oil. Most (65%) respondents indicate they aspired to be among the first farmers in their area to grow and sell hemp. Growers who have tried new crops or new farming technology in the last three years were more likely to adopt industrial hemp production. These findings will help decision-makers understand the critical concerns of growers who are willing to adopt industrial hemp as an alternative income-generating enterprise.

Abstract In 2014, Congress removed industrial hemp with a concentration of ≥0.3% tetrahydrocannabinol (THC) dry weight from the definition of marijuana in the federal Controlled Substances Act (CSA). Hemp production was authorized in a limited pilot program until 2018, when Congress passed the Agricultural Improvement Act (Farm Bill) that expanded the program to anyone licensed to produce hemp by the U.S. Department of Agriculture (USDA) or by a USDA-approved State or Indian tribe. Hemp’s greatest value is in two of its 80-plus molecules: cannabidiol (CBD) and THC. These molecules, present in all forms of Cannabis sativa L. (cannabis), including hemp, have medicinal and recreational uses. By removing hemp from the CSA, the Farm Bill altered the legal status of hemp’s extracts, including CBD and THC. In 2018, Epidiolex®, the world’s first and only CBD-based medicine, was approved in the U.S. The drug was placed in Schedule V of the CSA to comply with an international drug treaty requiring control of cannabis and all its extracts. In April 2020, Epidiolex was removed from the CSA schedules. This occurred, according to the Drug Enforcement Administration (DEA), because with a THC content below 0.3%, Epidiolex no longer met the Farm Bill’s criteria as a controlled substance. This review discusses the Farm Bill’s hemp provisions and how they have affected the legal status of hemp derivatives CBD and THC. The review also discusses a loophole in the Farm Bill that decriminalizes the production of marijuana by negligent hemp farmers. In passing, we discuss how lobbying by the hemp/CBD industry influenced passage of the Farm Bill.

There has been a resurgence in the cultivation of industrial hemp, Cannabis sativa L., in the United States since its recent legalization. This may facilitate increased populations of arthropods associated with the plant. Hemp pests target highly marketable parts of the plant, such as flowers, stalks, and leaves, which ultimately results in a decline in the quality. Industrial hemp can be used for several purposes including production of fiber, grain, and cannabidiol. Thus, proper management of pests is essential to achieve a substantial yield of hemp in the face of climate change. In this review, we provide updates on various arthropods associated with industrial hemp in the United States and examine the potential impact of climate change on corn earworm (CEW) Helicoverpa zea Boddie, a major hemp pest. For example, temperature and photoperiod affect the development and diapause process in CEW. Additionally, drought can lead to a reduction in hemp growth. Host plant diversity of CEW may prevent populations of the pest from reaching outbreak levels. It is suggested that hemp varieties resistant to drought, high soil salinity, cold, heat, humidity, and common pests and diseases should be selected. Ongoing research on effective management of CEW in hemp is critical.

Summary: In the United States' normative population for the WAIS-R, differences (Ds) between persons' verbal and performance IQs (VIQs and PIQs) tend to increase with an increase in full scale IQs (FSIQs). This suggests that norm-referenced interpretations of Ds should take FSIQs into account. Two new graphs are presented to facilitate this type of interpretation. One of these graphs estimates the mean of absolute values of D (called typical D) at each FSIQ level of the US normative population. The other graph estimates the absolute value of D that is exceeded only 5% of the time (called abnormal D) at each FSIQ level of this population. A graph for the identification of conventional “statistically significant Ds” (also called “reliable Ds”) is also presented. A reliable D is defined in the context of classical true score theory as an absolute D that is unlikely (p < .05) to be exceeded by a person whose true VIQ and PIQ are equal. As conventionally defined reliable Ds do not depend on the FSIQ. The graphs of typical and abnormal Ds are based on quadratic models of the relation of sizes of Ds to FSIQs. These models are generalizations of models described in Hsu (1996) . The new graphical method of identifying Abnormal Ds is compared to the conventional Payne-Jones method of identifying these Ds. Implications of the three juxtaposed graphs for the interpretation of VIQ-PIQ differences are discussed.

This essay argues that in spite of their obvious Biblically-based subject matter, clear Christian content, and undeniable evangelical perspective, the Left Behind novels for kids are not simply religious books; they are also political ones. Co-authors Tim LaHaye and Jerry B. Jenkins may claim that their narratives are interested in sharing the good news about Jesus for the sake of the future, but they are equally concerned with offering commentary on contentious US cultural issues in the present. Given the books’ adolescent readership, they are especially preoccupied with the ongoing conservative crusade concerning school prayer. As advocates for this issue, LaHaye and Jenkins make use of a potent blend of current socio-political arguments and of past events in evangelical church history: namely, the American Sunday School Movement (ASSM). These free, open-access Sabbath schools became the model for the public education system in the United States. In drawing on this history, the Left Behind series suggests that the ASSM provides an important precedent for the presence not simply of Christianity in the nation's public school system, but of evangelical faith in particular.
