“…Additional research on hemp is needed if hemp production is to expand, particularly in the United States. Globally, potential yield losses are greater from weeds than other pests in major crops (Oerke, ) with estimates of economic losses in the United States of $27 billion per year just for maize (if weeds remain uncontrolled) (Soltani et al ., ). Minor crops, such as hemp, may be particularly affected by weeds, due to a lack of registered herbicides.…”

Summary Industrial hemp (Cannabis sativa L.) is grown in more than 30 countries for fibre, seed and flowers, and acreage of cultivation is increasing globally. Hemp has long been promoted as a crop that competes well with weeds and requires little intervention to prevent yield losses. We conducted a literature review and found little peer‐reviewed research to support this claim. We identified only three articles that specifically addressed weed management under field conditions and none provided information on hemp yield losses from weeds. These findings highlight a clear need for research‐based information on interactions between weeds and hemp to address potential yield losses under various production conditions and provide a research‐based framework for weed management in industrial hemp.

“…Recent evaluations for potential corn yield losses from weeds (in the absence of weed management) in North America put the figure at ca. 50% [86]. Overall, pest management per se, is a crucial aspect of maintaining production in agriculture and other managed systems.…”

Climate Change, Carbon Dioxide, and Pest Biology, Managing the Future: Coffee as a Case Study

The challenge of maintaining sufficient food, feed, fiber, and forests, for a projected end of century population of between 9-10 billion in the context of a climate averaging 2-4 • C warmer, is a global imperative. However, climate change is likely to alter the geographic ranges and impacts for a variety of insect pests, plant pathogens, and weeds, and the consequences for managed systems, particularly agriculture, remain uncertain. That uncertainty is related, in part, to whether pest management practices (e.g., biological, chemical, cultural, etc.) can adapt to climate/CO 2 induced changes in pest biology to minimize potential loss. The ongoing and projected changes in CO 2 , environment, managed plant systems, and pest interactions, necessitates an assessment of current management practices and, if warranted, development of viable alternative strategies to counter damage from invasive alien species and evolving native pest populations. We provide an overview of the interactions regarding pest biology and climate/CO 2 ; assess these interactions currently using coffee as a case study; identify the potential vulnerabilities regarding future pest impacts; and discuss possible adaptive strategies, including early detection and rapid response via EDDMapS (Early Detection & Distribution Mapping System), and integrated pest management (IPM), as adaptive means to improve monitoring pest movements and minimizing biotic losses while improving the efficacy of pest control.can encompass simple to sophisticated strategies (e.g., from hoeing to modifying the environment to utilize ecosystem services) to manage pest populations and ensuing damage.Recent and projected increases in atmospheric carbon dioxide (CO 2 ) concentration are expected to continue with a potential 2× increase over current CO 2 levels, and subsequent, concomitant increases in average temperature between 0.15 and 0.3 • C, per decade, by 2100 [3,4]. Such projections, as well as recent potential changes in extreme events, increase the degree of uncertainty of how these environmental changes could impact pest biology (insects, plant pathogens, weeds), and the consequences for future biotic losses from managed plant systems.Recent and projected increases in atmospheric CO 2 could change pest biology in two essential ways. The first is related to physical changes in the environment incurred as CO 2 increases. Such increases, along with other radiation trapping gases (e.g., CH 4 , N 2 O), will increase surface temperatures [5], cause changes in precipitation frequency [6], and alter the diurnal temperature range (DTR) [7], as well as the magnitude and distribution of extreme weather events [8]. A second essential consequence is the "fertilization" effect of rising CO 2 on plant photosynthesis; approximately 95% of plant species, those that rely solely on the C 3 photosynthetic pathway, could increase growth and reproduction as CO 2 increases, including agronomic and invasive weeds. There are hundreds of studies and several meta-analyses showing that both recen...

“…Since plants were first domesticated ∼10,000 years ago, crop plants have been exposed to recurrent infestations by weed plants (Frenkel et al, 2017). To date, weeds are the most important biotic factor affecting agriculture production and causing yield losses in various crops worldwide [e.g., Corylus avellana (Kaya-Altop et al, 2016), Zea mays (Soltani et al, 2016) and Oryza sativa (Chauhan and Johnson, 2011; Chauhan and Opena, 2012)]. Strategies for weed control are based primarily on chemical control, since the last decades the use of synthetic chemical products has been dramatically increased (Sandín-España, 2011).…”

The use of herbicides has become a potential tool in modern agriculture to get rid of weeds menace, but unknowingly the indiscriminate application of herbicides has resulted in adverse effects on the morphological, physiological and biochemical characteristics of crop plants. Herbicide effect of triazine herbicide (solo applied, or in combinations with regulators of polyamine biosynthesis: γ-aminobutyric acid, propylenediamine and salicyl acid) and quantitative parameters of spring barley (variety Kompakt) was evaluated under simulative conditions of hydroponic experiments under light platform. The experiment was carried out in hydroponics under light platform with linear fluorescent lamp at Department of chemistry SUA Nitra, where 9 pots was used with 24 barley grains/per pot of variety Kompakt and 5.5 litres of mineral solution, which were prepared from stock solutions containing optimal content of macro-elements (K, P, N, Ca, Mg) and micro-elements (B, Mn, Cl, Zn, S, Cu, Mo, Fe) for plants. At hydroponic experiment short-time negative effect of triazine herbicide at formation of biomass and root system and more significant negative influence at the amount of formed fresh biomass and root system were observed. Our experiments after foliar treatment of barley plants with herbicide confirm minimal short-time negative effect of mentioned herbicide. It indicates lowering of the amount of retained water in roots. Regulators of polyamine biosynthesis in hydroponics reduced inhibitory effect of tested pesticide on formation of organic matter, while their influence was manifested on amount of produced fresh biomass and root matter than on amount of dry matter. The most suitable doses of 100 g.ha-1 degradation product putrescine - GABA (γ-amino-butyric acid) and 59.2 g.ha-1 degradation product spermidine and spermine - DAP (1,3- propylendiamine) were used on elimination of negative effects of triazine herbicide in barley.
